DETAILED DESCRIPTION OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a method for controlling the display of a screen displayed on a display device of a computer, for example and, more particularly, to a method for verifying a read image on a screen by recognizing a character. [0003] 2. Background Art [0004] One of the methods for reading a character or figure is an optical character recognition (hereinafter referred to as OCR). An OCR apparatus or a computer having the OCR function recognizes (specifies) a character or figure as a predetermined pattern by reading optically an image of the character or figure, and comparing it with the reference pattern. The OCR apparatus or computer of this type handles a large amount of different kinds of patterns, and may make an error recognition result. Therefore, the recognition result is checked through the visual inspection of the operator, and if mis-recognized, the recognition result must be corrected. [0005] A typical user interface for use in comparing the character image and the recognition result character involves a combination of a display area of read character image and a display area of recognition result character (standard pattern). [0006] FIG. 19 is a view showing an example of a verification screen for verifying the character image and the recognition result. As shown in FIG. 19, the verification screen is designed by arranging various display areas in a predetermined form. The character image read (hereinafter referred to as scanned) in accordance with a format of document and the recognition result of this character image are output to a predetermined area of this verification screen. In the illustrated example, a character image display area 2110 and a recognition result display area 2120 for displaying the recognition result of this character image are arranged in two rows in the verification screen. Problems to be Solved by the Invention [0007] In employing a business application for recognizing a character, outputting the recognition result and verifying the output result, the arrangement of GUI parts on the verification screen as the user interface greatly affects the efficiency of operator's verification operation. In the conventional verification screen, the operator had to compare the character image read from each field of the document and the recognition result for each character for verification. For each document, the user needed to read the character image and the recognition result and repeat the verification operation for each character. In this manner, a complex operation was required for verifying the recognition result. Namely, the verification operation by the operator was bad in the operation efficiency, and not expected to have high throughput. [0008] To verify the character images arranged for each field and the recognition result, the operator must always move the line of sight up or down and left or right, so that the operator's eyes are very tired by repeating this movement for a long time. [0009] A user interface may be provided in which a plurality of character images having the same recognition result can be arranged and compared with the recognition result character for verification. In this case, when the operator makes visual inspection, it is unnecessary to move the line of sight to the recognition result character for each character, whereby the burden is relieved. However, in the case of employing such a method, it is a burden for the operator to move the line of sight to all the character images, and there is a risk of the column skip or line skip during verification, resulting in a check error (missing check). [0010] Thus, it is an object of the present invention to design a screen with the user interface in which the scanned character can be verified at higher productivity and with less burden and fatigue of the operator. [0011] Also, it is another object of the invention to provide a method for controlling the display of a screen in which a difference between a scanned image and the recognition result can be discriminated intuitively and easily. SUMMARY OF THE INVENTION [0012] In order to accomplish the above objects, the present invention is implemented as a method for controlling the display of a screen which allows the user to verify the recognition result of a symbol, employing a computer. That is, this display control method comprises a step of reading a plurality of symbol images recognized as a specific symbol stored in a memory upon an operation of the user, and a step of displaying sequentially the plurality of read symbol images on the verification screen of a display device. This display method further comprises a step of reading the standard pattern of the specific symbol stored in the memory upon an operation of the user, as well as displaying the standard pattern on the verification screen of the display device. [0013] This display method comprises displaying a newly displayed symbol image and the already displayed symbol images in a list format in displaying the plurality of symbol images. Also, this display method comprises displaying the newly displayed symbol image at a predetermined position sequentially, and displaying the already displayed symbol images at the positions shifted each one column from the predetermined position, in displaying the plurality of symbol images. [0014] Also, this invention is implemented as a program for executing a process for each step of the display control method on a computer. This program is provided by being stored in a magnetic disk, an optical disk, a semiconductor memory or other recording medium, or distributed via the network. [0015] Through these processes, the display control can be suitably made to allow the user to verify the recognition result of the symbol, whereby the user can find the mis-recognized symbol image intuitively and easily. [0016] Also, this invention to accomplish another object is implemented as an information processing apparatus that is configured in the following way. That is, an information processing apparatus for displaying the recognition result of figure on a predetermined screen comprises graphics image display means for displaying sequentially a recognized graphic image on the screen, and graphics image list display means for displaying the sequentially displayed graphics images in a list format on the screen. This information processing apparatus further comprises recognition result image display means for displaying the standard pattern indicating the recognized image at a predetermined position on the screen. [0017] The display means can display the information at predetermined positions on the verification screen of the recognition result which is suitable for discriminating the mis-recognized graphics image. [0018] Moreover, this invention is implemented as an information processing apparatus that is configured in the following way. That is, this information processing apparatus comprises a display unit for displaying a predetermined screen, a display control section for generating the screen for verifying the recognition result of a symbol and displaying the screen on the display unit, and an operation accepting section for accepting an operation made on the screen. And the display control section controls the display contents that are displayed in a symbol image display area for displaying a recognized symbol image sequentially and in a symbol image list display area for displaying the symbol image displayed in the symbol image display area and the symbol images already displayed in the symbol image display area. Also, this display control section controls the display contents that are displayed in a recognition result symbol display area for displaying the standard pattern indicating the recognized symbol. And the display control section shifts by one character the already displayed symbol images, every time a new symbol image is displayed at a predetermined position in the symbol image list display area. [0019] This information processing apparatus further comprises a recognition result correcting section for correcting the recognition result of the symbol image displayed on the display unit, a symbol data storage section for storing and managing the symbol images grouped for every symbol code of the recognition result, and a document data storage section for storing and managing a document image from which the symbol image stored in the symbol data storage section is read. [0020] Moreover, this invention is implemented as an optical character recognizer that is configured in the following way. This optical character recognizer comprises character recognition means for recognizing a character image as a character, display means for displaying a predetermined screen providing a user interface, and display control means for controlling the display of the screen to be displayed on the display means. Herein, the display means displays a pair of display portions arranged at predetermined positions within the screen and a list display portion, and the display control means displays the standard pattern indicating the recognized character on one of the pair of display portions, and displays sequentially a recognized character image in the other of the pair of display portions and at a predetermined position of the list display portion. [0021] In this optical character recognizer, the pair of display portions are arranged adjacent to each other, and the list display portion is arranged near the pair of display portions. And this display control means displays sequentially a character image at a position of the list display portion divided into a matrix that is closest to the pair of display portions, and displays the already displayed character images in the list display portion at the positions becoming more distant from the pair of display portions as more character images are displayed sequentially. Also, this display control means may display a plurality of pairs of display portions. Continue reading...
