CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority to and incorporates by reference the entire contents of Japanese priority document 2007-065694 filed in Japan on March 14, 2007.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an image processing apparatus, a computer program product, and a preview image displaying method.

2. Description of the Related Art

A multi-function product, which is a so-called multi-function peripheral (MFP), has recently become widely used. An MFP includes a scanning unit that scans an image of an original, a copying unit that prints out an image read by the scanning unit, a printing unit or a facsimile unit that prints out image data that has been input externally, or provided with functions of the foregoing units.

With such an MFP, a user can enter settings for various functions. These functions include: settings relating to conditions of an original, such as a type or density thereof; settings relating to various imaging processes, such as an enlargement/reduction ratio, one-sided or double-sided printing, or margin sizes; and settings relating to finishing processes, such as stamping, stapling, or punching.

However, even if the user specifies settings for these finishing functions, known MFPs do not allow the user to check how a resultant printout will be until the resultant printout is actually output. For example, if the user attempts to punch holes on the printout, the holes may end up being punched on an output image. However, because the user cannot check such an end result before executing the actual printing, the operation may result in a misprint, and the paper may be wasted.

Japanese Patent Application Laid-open No. 2001-67347 discloses an image processing apparatus developed in an attempt to solve this problem. The image processing apparatus displays a preview image of end results of various functions (such as a printing paper size, a printed side(s) thereof, punching, or stapling) provided using a pre-scanned image of an original before executing actual printing. This preview feature allows the user to check how the output result will be, and to change the settings if necessary.

The applicant of the present application has developed an intuitive and convenient user interface in Japanese Patent Application Laid-open No. 2006-003568. This interface enables the user to touch a specific area of the preview image of an original to cause a menu related to that area to be displayed, and to select functions related thereto (such as a printing paper, a printed side(s), punching, stapling, output color, output density, enlargement/reduction ratio, printing multiple pages per sheet, and sorting/stacking), and the selected settings are immediately reflected onto the preview image.

Upon printing images onto a plurality of printing paper sheets, the front side and the back side of the paper need to be distinguished because images printed thereon are interrelated to each other. However, it is difficult for the user to determine if the image displayed on a screen is a front side image or a back side image. In addition, upon binding a plurality of sheets, such as by stapling, the user needs to be able to check if each of the sheets is oriented correctly, and if a given page is in a correct position with respect to the page prior to or the page next to that page in question.

In addition, upon scanning and processing originals with images printed thereon, pages of the originals could be arranged out of order, unlike image data that is created on a computer and is arranged in order. For example, the front side images and the back side images may be mixed up; some pages may be oriented incorrectly; or some pages may be placed in an incorrect position with respect to the page prior to or next to the page in question. Therefore, it is important for the user to be able to check how an end result will be.

DETAILED DESCRIPTION

OF THE PREFERRED EMBODIMENTS

Exemplary embodiments of the present invention are explained in detail below with reference to the accompanying drawings.

A first embodiment of the present invention is explained with reference to FIGS. 1 to 6. In the first embodiment, a multifunction peripheral (MFP), including functions such as coping, facsimile, printing, scanning, and distributing, is used as the image processing apparatus. The distributing function is a function that distributes an input image (such as an image of an original scanned by the scanning function, or an image input via the printing or the facsimile function).

FIG. 1 is a functional block diagram of an MFP 10 according to the first embodiment. The MFP 10 includes a scanner 11, an auto document feeder (ADF) 111, a scanner controller 112, an image storage unit 12, an image processing unit 13, a printer 14, a printer controller 142, a finishing processor 141, an operation displaying unit 15, an operation displaying unit controller 151, a system controlling unit 16, and a communication controlling unit 17. The MFP 10 is connected to a network 18 via the communication controlling unit 17. The MFP 10 scans an image of an original 19, performs imaging processes thereto, and outputs the image as a printout 20.

The system controlling unit 16 is connected to each of the above-described components, and controls the entire MFP 10. One example of the controls performed by the system controlling unit 16 is to provide the scanner 11 with information indicative of a scanning area suitable for a selected paper size. The system controlling unit 16 includes a central processing unit (CPU), a read-only memory (ROM), and a random access memory (RAM), each of which is not shown. The CPU operates according to computer programs that are stored in the ROM, using a working area in the RAM, to execute various functions.

The computer programs executed in the MFP 10 can be stored in a computer-readable storage medium, such as a compact disc-read only memory (CD-ROM), a flexible disk (FD), a compact disc-recordable (CD-R), or a digital versatile disk (DVD) as files in an installable or an executable format. If the computer programs are stored in such a storage medium, the CPU in the system controlling unit 16 reads and loads the computer programs from the storage medium onto a main storage device (not shown), to realize the various functions of the MFP 10. The computer programs can be stored in another computer connected to the network 18, such as an Internet, and downloaded over the network 18. Alternatively, the computer programs can be provided or distributed via a network, such as the Internet.

The communication controlling unit 17 is connected to the network 18, such as a local area network (LAN) or the Internet, and exchanges image data and control data with other apparatus connected to the network, following communication protocols.

The scanner controller 112 receives instructions from the system controlling unit 16 to control the scanner 11. The scanner 11 is controlled by the scanner controller 112 to convert an image of the original 19 to digital image data. The ADF 111 can feed a plurality of originals to a scanning position of the scanner 11 one by one, so that the scanner 11 can automatically scan the originals continuously. The ADF 111 can reverse both an original with an image printed on one side and an original with images printed on both sides, and send them to the scanner 11. Therefore, the scanner 11 can scan images printed on both sides of an original.

The image storage unit 12 is a buffer memory that receives an instruction from the system controlling unit 16 to temporarily store therein image data scanned by the scanner 11, image data externally input via the network 18, or the like. The MFP 10 is capable of processing and providing an image forming process to either the image data scanned by the scanner 11, or the image data that is externally input, for example, via the network 18.

The image processing unit 13 receives an instruction from the system controlling unit 16 to provide a y correction, a modulation transfer function (MTF) correction, or the like, and then to provide gradation processes, such as slicing or dithering to binarize (or multi-value) multi-valued data sent from the scanner 11 and stored temporarily in the image storage unit 12. In addition to the above, the image processing unit 13 performs various image processes (such as enlargement/reduction of an image, adjustment of density/colors of an image) for the functions set by a user. Furthermore, the image processing unit 13 performs an image area editing process (such as removing, moving, and reversing an image area), a layout process (such as double-sided/single-sided printing, multiple-pages-per-sheet printing, and margin adjustment), and an end-result information generating process for generating a preview image of the resultant printout.

The image processing unit 13 includes an end-result information generator 131, an input-screen information generator 132, and a setting unit 133. The end-result information generator 131 basically functions to generate the end result information (preview images) to be displayed on a display panel 15b. The end result information is generated by providing various processes and settings to the image data of a pre-scanned original, based on the various settings input for that image data. The end-result information generator 131 uses the multi-valued data temporarily stored in the image storage unit 12. The input-screen information generator 132 generates information about an input screen to be displayed on the display panel 15b. The information includes setting items for receiving therethrough various settings relating to the end result information generated by the end-result information generator 131.

If a user enters settings via an input screen 400 that is displayed on the display panel 15b, using a touch panel 15a, the setting unit 133 not only receives the input signals, but also obtains coordinate information in the input image stored in the image storage unit 12.

When the setting unit 133 receives the input setting signals, the end-result information generator 131 generates updated end result information again based on the input setting signals received by the setting unit 133, and an expected end result image, updated by the updated end result information, is displayed on the display panel 15b.

The input-screen information generator 132 generates input screen information for generating a screen for receiving settings input by the user, again, based on the input setting signals received by the setting unit 133. The input screen 400 is then updated based on the input screen information generated by the input-screen information generator 132, and displayed on the display panel 15b.

The printer controller 142 receives an instruction from the system controlling unit 16 to control the printer 14. The printer 14 includes the finishing processor 141. The finishing processor 141 receives automatic settings or settings by the user to perform finishing processes such as sorting, stamping, stapling, or punching. Sorting is a process to sort the printouts 20 into sets or units of pages after printing is completed. Stamping is a process to provide a given stamp to a printed medium. Stapling is a process to align a plurality of printed media and to staple together. Punching is a process to punch holes so that the printed media can be filed in a binder or a file.

The operation displaying unit controller 151 functions as a displaying unit, and controls inputs and outputs to/from the operation displaying unit 15 in response to the instructions received from the system controlling unit 16. For example, the operation displaying unit controller 151 controls to output data processed in the image processing unit 13 therefrom to the touch panel 15a and the display panel 15b that are provided to the operation displaying unit 15. More specifically, the operation displaying unit controller 151 causes the generated end result information (preview image) to be displayed on the display panel 15b, and controls inputs entered by the user via the touch panel 15a. The display panel 15b and the touch panel 15a are shown to be separate units in FIG. 1. However, they are integrated in the first embodiment.

The touch panel 15a electrically or magnetically detects a position of a pointer in contact therewith. A human finger, a stylus pen, and other contact-type input instruments (hereinafter, “pointer”) can be used as a pointing unit (not shown) for the touch panel 15a. The user enters various settings, including those for the printing, by touching the touch panel 15a using one of these pointers.

In the first embodiment, the settings are explained to be input by the user touching the touch panel 15a, however, it is not limited to such an inputting method. For example, in addition to the touch panel 15a, the operation displaying unit 15 can include hardware keys to allow the user to input the settings by pushing the physical keys to provide instructions, such as a print instruction. Moreover, the MFP 10 can include the display panel 15b as a dedicated displaying unit.

Under the control of the operation displaying unit controller 151, the operation displaying unit 15 receives the settings input by the user via the touch panel 15a, and displays the end result information (preview image) or menu items in a setting area for setting finishing processes on the display panel 15b as a displaying unit.

The operation displaying unit 15 displays functions that the user wishes to execute with the MFP 10 as menu items in the setting screen. The user can enter settings through these menu items, and the operation displaying unit 15 receives the settings entered by the user. When the user touches the touch panel 15a with a pointer in a section where a menu item can be selected, the operation displaying unit controller 151 detects coordinates of the touched point. If the operation displaying unit controller 151 detects that the touched point is within an area where a given menu item can be selected, then the operation displaying unit controller 151 assumes that the menu item has been selected, and accepts the input for the menu item. The operation displaying unit 15 receives settings, such as: condition settings for scanning a specific original with the scanner 11; settings for the image processing unit 13 for performing processes such as image quality adjustment of the scanned image data; printing condition settings for the printer 14; or settings for the finishing processor 141 for performing finishing processes such as sorting, stapling, or punching, to the printouts after printing is completed.

The system controlling unit 16 receives various settings such as those described above via the operation displaying unit controller 151, and causes the image processing unit 13 to process the original image data that is stored in the image storage unit 12 based on the specified settings, and to generate end result information (preview image). The end result information (preview image) is sent to the operation displaying unit 15, and displayed on the display panel 15b.

FIG. 2 is a schematic diagram of an example of end result information (preview image) generated when image data is input to the MFP 10. FIG. 2 is an example of displayed end result information obtained by continuously scanning both sides of the originals by the scanner 11. End result information (preview image) 401 and setting menu items 402 are displayed on the display panel 15b in the operation displaying unit 15. Page-forward and page-back buttons 600 enable the user to scroll the pages in a back and forward direction.

In this example, as mentioned above, both sides of the originals are scanned by the scanner 11. Therefore, the input screen 400, displayed on the display panel 15b, includes a plurality of end result information (preview images) 401, and the images are arranged in the order scanned by the scanner 11. The user can input various settings to end result information (preview image) 401a among the end result information (preview images) 401. The end result information (preview image) 401a is enlarged in size and is called a “detailed image”. Other secondary end result information (preview images) 401, except for the end result information (preview image) 401a, are called “summary images”. In FIG. 2, the end result information (preview image) 401a shows an image of the front side of a first sheet (the first page); the end result information (preview image) 401b shows an image of the back side of the first sheet (the second page); the end result information (preview image) 401c shows an image of the front side of a second sheet (the third page); and the end result information (preview image) 401d shows an image of the back side of the second sheet (the fourth page). In this manner, a preview displaying unit is realized.

According to the first embodiment, the detailed image is positioned adjacent to one of the summary images to form a pair, at an approximate center of the input screen 400. Nearby this pair, the remaining pair of the summary images is arranged. In FIG. 2, which is showing an initial state of the input screen 400, a pair of summary images is shown only at the right side at the center. However, the pair of summary images can be also displayed at the left upon the user scrolling the pages.

The setting menu items 402 include those for a menu 402a and a menu 402b. The menu 402a is displayed on the right side of the screen, and includes position-dependent setting menu items that are dependent on positions in the end result information (preview image) 401. Examples of the position-dependent setting menu items include finishing processes, such as stapling, punching, adjusting binding margins, erasing a frame, stamping, or assigning page numbers. The menu 402b is displayed on the left side of the display, and includes setting menu items that are not dependent on content, such as output color, output density, paper size, enlargement/reduction ratio, double-sided/single-sided printing, multiple-pages-per-sheet printing, sorting/stacking, or background.

The user touches the touch panel 15a with the pointer while looking at the end result information (preview image) 401 displayed on the display panel 15b. The touch panel 15a accepts the touch made by the pointer as an input of position information, which is a spatial position of the resultant printout on the end result information (preview image) 401. The setting unit 133 analyzes the position information accepted by the touch panel 15a, and obtains coordinate information of the position that the pointer touched on the image.

With such structure, the MFP 10 can display the end result information (preview image) 401 on the display panel 15b provided to the operation displaying unit 15 of the MFP 10 before actually printing a copy. Therefore, the user can visually check the end result information (preview image) and change the settings, if necessary, before executing the actual printing.

As shown in FIG. 3, it is assumed that the user selects a punching operation 403 from the setting menu items 402 (402a), displayed on the operation displaying unit 15, by touching it.

The operation displaying unit 15 detects the input for the punching operation 403, and the system controlling unit 16 accepts the setting of the punching operation 403 via the operation displaying unit controller 151. The input-screen information generator 132 in the image processing unit 13 obtains settable areas 404 and 405, corresponding to the “punching”, from a table shown in FIG. 4 in which each of the setting menu items 402 and its settable positions are associated with each other, and displays the settable areas 404 and 405 on the operation displaying unit 15. The settable areas 404 and 405, where the holes can be punched, can be displayed in the end result information (preview image) 401 in any manner. For example, the settable areas 404 and 405 can be displayed so that they are superposed on the end result information 401 or they are overwritten on the end result information 401. Alternatively, the settable areas 404 and 405 can be provided with a color different from that of the end result information 401, blinked, or the area except the settable areas 404 and 405 can be darkened. The settable positions in the table shown in FIG. 4 are defined as two coordinate points defining a diagonal. The diagonal connecting these two coordinate points defines a rectangle having one side parallel to a main scanning direction and the other side parallel to a sub-scanning direction. For example, the settable areas for the “stapling” operation are defined by coordinates (0, 0) and (40, 40), and (120, 0) and (160, 40).

The user selects and touches the settable area 404 as shown in FIG. 3 with the pointer. When the operation displaying unit 15 accepts the input by way of the pointer touching the settable area 404 for the punching operation 403, the end-result information generator 131 in the image processing unit 13 generates end result information (preview image) with holes punched in the accepted area, and sends the information to the operation displaying unit 15. In response, the information is displayed on the operation displaying unit 15. FIG. 5 is a schematic diagram of the end result information (preview image) 401 with holes 406 punched. The end result information (preview image) 401, displayed in the process described above, can accept further inputs for settings, for example, to make corrections. The accepted settings are reflected to the end result information (preview image) 401 again, and displayed on the operation displaying unit 15. If no further setting inputs are accepted, a print instruction is accepted.

In FIG. 5, the end result information (preview images) 401 are shown to be punched with the holes 406. The end result information (preview image) 401 of the first page has the holes on the left side, and the end result information (preview image) 401 of the second page has the holes on the right side. In other words, according to the first embodiment, a processed position or area, or a position where a given process is affected, can be displayed on both pages of front and back sides of an original, or of a two-page spread, at areas associated with that given process. In addition, as shown in FIG. 5, if the processes are those whose processed position changes depending on whether the page is a front side or a back side of an original, or a right page or a left page of a two-page spread, the processed position can be changed depending on whether the page selected for operation is on the front side or the back side. Example of such a process, for which the processed position changes depending on whether the page is on the front side or the back side, include settings for binding (stapling or punching), margins, and those for moving or deleting an image. In this manner, a process setting position changing unit is realized.

When a user selects a function that leads to different results depending on which side of an original the process is provided to, a message can be provided in a pop-up window, a dialogue, or a description section, prompting the user to distinguish the sides of the page or to check the settings for the selected function. Furthermore, not only prompting the user, but the settable information can be also displayed for the function whose processed position changes depending on which side of an original the process is provided to. For example, it is assumed herein that the user touched the upper end of the end result information (preview image) 401 (401a) when a back side is being displayed. It is acceptable to provide staples to the specified position if the displayed page were a front side. However, it is not acceptable to provide staples to the specified position on a back side. Therefore, other functions that are acceptable to provide at the upper end of the back side can be displayed, as well as a dialogue saying “the current image is a back side”. In addition, the stapling menu can be provided at the bottom end of the end result information (preview image) 401 (401a). It is also effective to prompt the user, for example using a dialogue, for a function, such as margin settings, whose settings affect the settings of the other side. In this manner, a notifying unit is realized.

The configuration can be such that when the user touches a specific area (not shown) in the preview image, menu items relating to the area is displayed. When the user selects one of the menu items, the selection can be immediately reflected to the preview image.

A preview image scrolling process, which is a characterizing process performed by the CPU in the system controlling unit 16 executing the computer programs stored in the ROM is explained.

As shown in FIG. 2, at an initial state, a detailed image is positioned adjacent to a summary image to form a pair, at the approximate center of the input screen 400. Nearby this pair, another pair of the summary images is arranged.

At this initial state, if the user operates any of the page-forward and page-back buttons 600, the operation displaying unit 15 detects the input to the page-forward and page-back buttons 600 by way of the user touching thereto. Via the operation displaying unit controller 151, the system controlling unit 16 receives the operation of the page-forward and page-back buttons 600. Upon receiving the operation performed by the page-forward and page-back buttons 600, the system controlling unit 16 controls the input-screen information generator 132 in the image processing unit 13, and causes the input-screen information generator 132 to generate the input screen 400 having the end result information (preview images) 401 with a page scrolled in a forward or backward direction. The resultant input screen 400 is then displayed on the operation displaying unit 15 via the operation displaying unit controller 151.

One example of a method for generating the input screen 400 in the input-screen information generator 132 is explained. The input screen 400 includes the end result information (preview images) 401 with a page scrolled in a forward or backward direction. FIGS. 6A to 6C are schematic diagrams for explaining an exemplary preview image scrolling method. When the user operates the page-forward and page-back buttons 600 and the system controlling unit 16 accepts a page-forward operation for scrolling one page at a time, the input-screen information generator 132 generates the input screen 400 having end result information (preview images) 401 with one page scrolled forward at a time in the detailed image 401a, as shown in FIGS. 6A to 6C. In other words, every time the user scrolls one page at a time while the double-sided printing is selected in the manner described in the first embodiment, images of front and back side of an original (FIGS. 6A and 6C) and those of a two-page spread (FIG. 6B) are alternately displayed as a pair of a detailed image and a summary image. In this manner, a page scrolling unit is realized.

As described above, according to the first embodiment, upon performing a double-sided printing, images of the front and the back sides of an original, or images on the two-page spread can be paired as a detailed image and a summary image, and at least one of the paired images to be processed can be displayed. Therefore, the user can easily imagine how the end result will be, including pages of the front and back sides of an original and pages on the two-page spread. In addition, because only one page is enlarged as a detailed image within a limited space in the display, the detailed image helps the user to understand the page layout easily. Therefore, the user can easily check how the end result will be with the double-sided printing within a limited space in the display, as well as which side of the original is to be bounded together.

As to which side of the original image is to be used as an axis of two-page spread, the user makes a decision whether the shorter side or the longer side thereof should be used. According to the first embodiment, it is explained that the user specifies the longer side of the original image as the axis. If the user selects the shorter side of the original image as the axis of the two-page spread while the display panel 15b of the operation displaying unit 15 is long in the horizontal direction, it is difficult to display such end result information (preview images) 401 within the display panel 15b in the same direction as shown in FIG. 2. More specifically, if the end result information (preview images) 401 are to be arranged in the vertical direction (the two pages are to be spread out vertically) on the display panel 15b in the same direction as shown in FIG. 2, it is necessary to reduce the size of the end result information (preview images) 401 greatly. Therefore, according to the first embodiment, as shown in FIGS. 7A and 7B, if the user specifies the shorter side of the original image as the axis of the two-page spread, the end result information (preview images) 401 are rotated, upon being displayed, by 90 degrees with respect to the image having the axis of the two-page spread on the longer side thereof. In FIG. 7A, the display panel 15b of the operation displaying unit 15 is used as a horizontally-long panel. In FIG. 7B, the display panel 15b of the operation displaying unit 15 is used as a vertically-long panel. Therefore, the display panel 15b can easily display a two-page spread image having an axis on the shorter side of the original image. In this manner, a rotation unit is realized. If the user selects the shorter side of the preview image to be the axis of the two-page spread, the rotation unit rotates the preview image by 90 degrees with respect to a two-page spread image having its axis on the longer side of the preview image.

According to the first embodiment, the summary image paired with the detailed image is displayed reduced in size. However, a displaying method of the summary image is not limited to the above, and the summary image can also be displayed as a symbol or an icon (hereinafter, “symbol image”). If the summary image is displayed as a symbol image, it is possible to omit the process for reducing the image size, making a processing time faster. In addition, by providing a plurality of symbol images, the user can easily scroll to a page away from a currently-selected page. The symbol image representing the page prior to or next to the current page can also be shown in different colors, each color corresponding to the front side and the back side, respectively, facilitating the user to scroll through pages of the same side.

According to the first embodiment, a detailed image and a summary image that are pages of the front side and the back side of an original or pages of a two-page spread, are displayed adjacently as a pair. However, a displaying method of these images is not limited to the above. For example, alternatives below are also possible.

To begin with, if a pair of the pages is the front side and the back side of an original, or makes up a two-page spread, a zoom-in images of the detailed image and the summary image can be provided, as shown in FIG. 8. At this time, the detailed image is shown in its entirety, and the summary image shown only partly. Then, if a pair of the pages is the front side and the back side of an original, the summary image can be displayed transparently with respect to the detailed image, as shown in FIG. 9. Then, if a pair of the pages is the front side and the back side of an original, the summary image can be displayed as a mirrored image with respect to the detailed image, as shown in FIG. 10. Then, if a pair of the pages is the front side and the back side of an original, or makes up a two-page spread, the summary image can be arranged adjacent to the detailed image in a shape like a folding screen, as shown in FIG. 11.

A second embodiment of the present invention is explained with reference to FIGS. 12A to 12C. The same components as in the first embodiment are provided with the same reference numbers, and the explanations thereof are omitted herein. In the second embodiment, another preview image scrolling method is proposed, in addition to that in the first embodiment.

FIGS. 12A to 12C are schematic diagrams for explaining an exemplary preview image scrolling method according to the second embodiment. When the user operates the page-forward and page-back buttons 600 and the system controlling unit 16 accepts the page-forward operation to scroll one page at a time, the input-screen information generator 132 generates the input screen 400 having end result information (preview image) 401 with one page scrolled forward at a time in the detailed image 401a, as shown in FIGS. 12A to 12C. The second embodiment is different from the first different in that the pairs of summary images, representing the front side and the back side of an original, are always scrolled together in pairs near the detailed image 401a. In other words, if one page is scrolled at a time according to the second embodiment while a double-sided printing is selected, the pages are scrolled in pairs, each representing the front side and the back side of an original. More specifically, to begin with, the front side of the first sheet (the first page) is displayed as a detailed image, and the back side of the first sheet (the second page) is displayed as a summary image, as shown in FIG. 12A. When the page is scrolled, the front side of the first sheet (the first page) is displayed as a summary image, and the back side of the first sheet (the second page) is displayed as a detailed image, as shown in FIG. 12B. When the page is scrolled further, the front side of the second sheet (the third page) is displayed as a detailed image, and the back side of the second sheet (the forth page) is displayed as a summary image, as shown in FIG. 12C.

As described above, according to the second embodiment, when a double-sided printing is specified, the pairs of pages, each corresponding to the front side and the back side of an original, are displayed as pairs of the detailed image and the summary image within a limited space on the display screen. This displaying method does not only facilitate the user to imagine how the end result will be, but also enables the user to check contents of an enlarged page more easily, because each page in the page pair is enlarged as the detailed image. In this manner, the user can check how the end result will be with double-sided printing.

A third embodiment of the present invention is explained with reference to FIGS. 13A to 13C. The same components as in the first embodiment are provided with the same reference numbers, and the explanations thereof are omitted herein. In the third embodiment, another preview image scrolling method is proposed for the preview image, in addition to that in the first embodiment.

FIGS. 13A to 13C are schematic diagrams for explaining an exemplary preview image scrolling method according to the third embodiment. When the user operates the page-forward and page-back buttons 600 and the system controlling unit 16 accepts the page scrolling operation to scroll one page at a time, the input-screen information generator 132 generates the input screen 400 having the end result information (preview images) 401 with one page scrolled forward at a time in the detailed image 401a, as shown in FIGS. 13A to 13C. The third embodiment is different from the first embodiment in that pairs of summary images, representing a two-page spread of the original, are always scrolled together in pairs near the detailed image 401a. In other words, if the pages are scrolled one page at a time according to the third embodiment while double-sided printing is selected, the pages are scrolled in pairs, each representing a two-page spread. More specifically, to begin with, the front side of the first sheet (the first page) is displayed as a summary image, the back side of the first sheet (the second page) is displayed as a detailed image, and the front side of the second sheet is displayed as a summary image, as shown in FIG. 13A. When the page is scrolled, the back side of the first sheet (the second page) is displayed as a summary image, and the front side of the second sheet (the third page) is displayed as a detailed image, as shown in FIG. 13B. When the page is scrolled further, the back side of the second sheet (the fourth page) is displayed as a detailed image, and the front side of the third sheet (the fifth page) is displayed as a summary image, as shown in FIG. 13C.

According to the third embodiment, when the double-printing is selected, a two-page spread is displayed as a pair of a detailed image and a summary image within a limited space of the display screen, facilitating the user to imagine how the end result will be. Furthermore, each of the pages is enlarged as a detailed image, so that the user can easily check the contents thereof. In this manner, the user can easily check which side of the original is to be bounded, within the limited space on the display screen.

A fourth embodiment of the present invention is explained with reference to FIGS. 14A to 14C. The same components as in the first embodiment are provided with the same reference numbers, and the explanations thereof are omitted herein. In the first embodiment, only one page is scrolled at a time. On the contrary, in the forth embodiment, two pages are scrolled at a time when the user operates the page-forward and page-back buttons 600.

FIGS. 14A to 14C are schematic diagrams for explaining an exemplary preview image scrolling method according to the fourth embodiment. When the user operates the page-forward and page-back buttons 600 and the system controlling unit 16 accepts the page scrolling operation to scroll two pages at a time, then the page displayed in the detailed image 401a is scrolled by a two-page unit, as shown in FIGS. 14A and 14B. In addition, according to the fourth embodiment, a “turn over” button 601 is provided as one of the functions of the page-forward and page-back buttons 600. The “turn over” button 601 allows the user to switch between the detailed image and the summary image paired with the detailed image. When the system controlling unit 16 accepts the operation performed by the “turn over” button 601, the detailed image and the summary image are switched as shown in FIG. 14C. In this manner, a switching unit is realized. The switching unit switches a detailed image to be processed and a summary image paired with the detailed image.

A fifth embodiment of the present invention is explained with reference to FIGS. 15A and 15B. The same components as in the first embodiment are provided with the same reference numbers, and the explanations thereof are omitted herein. In the first embodiment, only one page is scrolled at a time. On the contrary, in the fifth embodiment, two pages are scrolled at a time when the user operates the page-forward and page-back buttons 600.

FIGS. 15A and 15B are schematic diagrams for explaining an exemplary preview image scrolling method according to the fifth embodiment. To begin with, only pages of front side images on originals are displayed as the end result information (preview images) 401, including the detailed image 401a, as shown in FIG. 15A. When the user operates the page-forward and page-back buttons 600 and the system controlling unit 16 accepts the page scrolling operation to scroll two pages at a time, the images displayed as the end result information (preview images) 401, including the detailed image 401a, are scrolled for two pages. In addition, according to the fifth embodiment, the “turn over” button 601 is provided as one of the functions of the page-forward and page-back buttons 600. The “turn over” button 601 allows the user to switch between the detailed image and the summary image paired with the detailed image. When the system controlling unit 16 accepts the operation performed by the “turn over” button 601, only pages of back side images on originals are displayed as the end result information (preview images) 401, including the detailed image 401a, as shown in FIG. 15B. In this manner, a replacing unit is realized. The replacing unit replaces a displayed primary preview image to be processed with a secondary preview image paired with the primary image.
