DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment

FIG. 1 schematically illustrates the display device employed to display image data files, which is provided with the data file management apparatus achieved in the first embodiment of the present invention. In FIG. 1, the image data file display device is achieved by connecting an electronic still camera 1 and a personal computer (PC) 2 through an IEEE-1394 cable 3. The electronic still camera 1 comprises an MPU 11, a CF card 12, an interface circuit 13 and an image capturing element 14. The electronic still camera 1 records image data obtained through an image capturing operation performed at the image capturing element 14 into the CF card 12 in a specific format. In addition, the electronic still camera 1 transfers the image data obtained through a photographing operation to the personal computer 2 via the interface circuit 13 and the IEEE-1394 cable 3. A transfer buffer memory 131 is provided at the interface circuit 13. The operation of the electronic still camera 1 is controlled by the MPU 11.

The personal computer 2 comprises an MPU 21, a recording device 22, an interface circuit 23, a display circuit 24 and a display device 25. The image data transferred from the electronic still camera 1 are taken into the personal computer 2 via the IEEE-1394 cable 3 and the interface circuit 23. The interface circuit 23 is provided with a transfer buffer memory 231. The image data taken into the personal computer 2 are recorded in a specific recording area in the recording device 22. The image data recorded in the recording device 22 are read out from the recording device 22 and converted to an image signal at the display circuit 24 and the resulting image signal is displayed at the display device 25 connected to the personal computer 2 via an image signal cable 26. The operation of the personal computer 2 is controlled by the MPU 21.

The image data having been taken into the personal computer 2 from the electronic still camera 1 are displayed at the display device 25 and, in addition, they are printed out at an output device (not shown) connected to the personal computer 2 or transmitted to another computer apparatus (not shown) which is capable of data exchange with the personal computer 2.

—Image Data File Names—

The recording areas in the recording device 22 are each made to correspond to the file name assigned to a given set of image data, and image data assigned with individual file names are recorded in the corresponding recording areas in the recording device 22.

The format in which the image data obtained by performing a photographing operation in the electronic still camera 1 and recorded in the CF card 12 is predetermined to match the format of the data managed in the personal computer so that the image data can be processed in the personal computer 2 and recorded images can be output to a display device or an output device (not shown). FIG. 2 is provided to facilitate an explanation of a data name assigned to image data obtained through a photographing operation performed in the electronic still camera 1 when they are recorded in the recording medium such as the CF card 12. In FIG. 2, a directory 110 “DCIM” is assigned under a root directory 100 in image data names in conformance to the DCF (Design Rules For Camera File Systems).

The so-called directory tree presented in FIG. 2 shows the structure of data files which are managed by, for instance, the personal computer 2. An explanation is given with regard to an image data name 120 provided under the directory 110. As shown in FIG. 2, the image data name 120 is constituted of a sub-directory 130 to which a plurality of names may be assigned and a file name 140 to which a plurality of names may be assigned provided under each sub-directory 130. This structure matches the DOS structure used in a system such as the personal computer 2 that handles the recording device. It is to be noted that in some personal computer basic programs (OS), directories are referred to as folders.

FIG. 3 is provided to facilitate an explanation of a sub-directory 130. The sub-directory 130 may be constituted of a numerical value portion 131 and a name portion 132. The numerical value portion 131 is constituted of a three-digit integer, whereas the name portion 132 is constituted of up to five alphanumeric characters or symbols. Different name portions 132 may be provided in the individual sub-directories 130, or a single name portion 130 may be used in different sub-directories 130. Even when the same name portion 132 is used, the sub-directories 130 can be distinguished from each other by assigning different integers in the numerical value portions 131 of the sub-directories 130.

FIG. 4 is provided to facilitate an explanation of a file name 140. The file name 140 may be constituted of, for instance, a header portion 141, a numerical value portion 142 and an extension 143. Four alphabetic characters are assigned in the header portion 141. “DSCN” in FIG. 4 indicates that the data assigned with a file name 140 are image data having been recorded in the electronic still camera 1. A four-digit integer is assigned in the numerical value portion 142. The extension 143, i.e., “JPG”, indicates that the image data assigned with the file name 140 are image data having been compressed in the JPG format. As explained above, by assigning a name constituted of the sub-directory 130 and the file name 140 to a set of image data having been recorded in the electronic still camera 1, the image data are readied to undergo processing in the personal computer 2.

—Prevention of Duplicate File Intake—

Next, an in-taken data management table is explained. The in-taken data management table is a management table provided to record in the recording device 22 four management items together, i.e., the folder name, the file name, the date on which the image data were obtained through a photographing operation and the file size of the image data with regard to each of the image data files recorded in the recording device 22. This management table is used to ensure that when electronic image data are transmitted from the electronic still camera to the personal computer 2 connected as shown in FIG. 1, image data which have already been recorded in the recording device 22 are not transmitted again. FIG. 5A shows image data files 600 recorded in the CF card 12 and FIG. 5B illustrates the in-taken data management table 601.

In FIG. 5A, sets of image data obtained by performing a photographing operation in the electronic still camera 1 are recorded in the CF card 12 with individual file names attached thereto as explained earlier. Three files having file names 140, i.e., “DSCN0001.JPG”-“DSCN0003.JPG” are recorded in a folder with its sub-directory 130 assigned as “100NIKON”. In addition, four files having file names 140, i.e., “DSCN0001.JPG”-“DSCN0004.JPG”, are recorded in a folder with its sub-directory 130 assigned as “101NIKON”. Let us now assume that the “DSCN0004.JPG” file in the “101NIKON” folder is to be provided to the personal computer 2 as a new file.

In FIG. 5B, the four management items explained above are recorded in correspondence to each file in the in-taken data management table 601. The management items managed by the in-taken data management table 601 are defined by an in-taken data management defining table 602. Namely, the data in the attribute data of each image data file recorded in the recording device 22, which correspond to the management items defined in the in-taken data management defining table 602, are prepared as table data and are recorded in the recording device 22 as the in-taken data management table 601. The attribute data include a plurality of types of information recorded in the CF card 12 as information indicating the intrinsic attributes of an image data file when image data are recorded as the image data file in the CF card 12 in the electronic still camera 1. They include photographing information such as the photographer\'s ID and the photographing conditions and a protector for preventing the file from being erased by mistake as well as the data corresponding to the four management items explained earlier.

The in-taken data management table 601 is updated each time a new image data file is recorded in the recording device 22. For instance, when the image data file with the file name “DSCN0004.JPG” in the folder having its sub-directory 130 assigned as “101NIKON”” is recorded in the recording device 22, the data indicating the management items with regard to this image data file are added to the in-taken data management table 601.

The management items are selected as appropriate so as to enable identification of the individual data files from the plurality of types of attribute data mentioned above. Thus, simply by checking the management item data recorded in the in-taken data management table 601 that are part of the attribute data of an image data file, a decision can be made as to whether or not the corresponding image data should be recorded in the recording device 22 without having to check the entire contents of the image data file. In other words, a decision can be made simply by checking the management item data alone as to whether or not the image data file in question represents image data that have already been recorded in the recording device 22.

The processing implemented to take an image data file into the personal computer 2 in the image data file display apparatus described above is now explained in reference to the flowchart of the processing procedure in FIG. 6. In FIG. 6, the processing starts when the electronic still camera 1 and the personal computer 2 become connected with each other via the IEEE-1394 cable 3 after a specific image data file intake program is started up on the personal computer 2. In step S61, the MPU 21 of the personal computer 2 issues a request to the electronic still camera 1 to transmit the attribute data alone to the personal computer 2. In response to the request for the attribute data, the MPU 11 of the electronic still camera 1 transmits the attribute data of the target file in the CF card 12 to the personal computer 2. When step S61 is implemented for the first time after starting the processing in FIG. 6, only the attribute data of the first image data file in the CF card 12, i.e., the image data file assigned with the file name “DSCN0001.JPG”, in the folder assigned with the folder name “100NIKON” are transmitted to the personal computer 2. In step S62, the MPU 21 of the personal computer 2 reads out data in the in-taken data management table 601 from the recording device 22 and then the operation proceeds to step S63.
