BEST MODE FOR CARRYING OUT THE INVENTION

-First Embodiment of the Invention- FIG. 1 shows a first example of displaying an image of a developed photographic film.
1 shows the configuration of the embodiment. The loaded developed film 21 is fed by a film feed control circuit 23 and a film feed mechanism 22, and an image of each frame is picked up by a CCD image pickup circuit 24. The captured image is processed by the image processing circuit 25, converted into digital image data, and transferred to the CPU 26. The film 21
Has a magnetic recording section for magnetically recording information, and can record various information for each frame.

[0007] The CPU 26 stores the image transferred from the image processing circuit 25 in the image memory 27. This image memory 27 is a so-called video RAM. The CPU 26 also stores the image stored in the image memory 27 into the large-capacity memory 2.
Transfer to 8. The large-capacity memory 28 is a memory having a large storage capacity such as a hard disk, a floppy disk, an MD, and an MO. As described above, the film 21 is fed to the imaging position one frame at a time, and the image of each frame is input. The input image is temporarily stored in the image memory 27, and is sequentially transferred and stored in the large-capacity memory 28.

[0008] The CPU 26 also generates a thumbnail image for each input image, and displays the thumbnail image on the image display circuit 29 and the display device 30. Here, the thumbnail image is an image in which a plurality of images are displayed in a list on one screen, and is also called an index image or a table of contents image. On the other hand, when there is a request to display an image of a specific frame by an operation input device (not shown), the CPU 26 stores the image of the requested frame from the large-capacity memory 28 to the image memory 27, and displays one screen on the display device 30 by the image display circuit 29. .

The operation of the first embodiment will be described with reference to FIGS. FIG. 2 is a flowchart showing an image storing operation. In step 301, the film 2 is controlled by the film feed control circuit 23 and the film feed mechanism 22.
1 is started, and in the next step 302, the first frame is CC
A predetermined imaging position of the D imaging circuit 24 is set. In step 303, an image is picked up by the CCD image pickup circuit 24, processed by the image processing circuit 25, and converted into digital image data. In step 304, the image transferred from the image processing circuit 25 is temporarily stored in the image memory 27.

In step 305, a thumbnail image is generated from the image stored in the image memory 27. In the following step 306, the image stored in the image memory 27 is transferred to the large capacity memory 28 and stored. Step 307
Sends the thumbnail image data to the image display circuit 29,
The thumbnail image is displayed on the display device 30. Step 3
In step 08, it is checked whether the image storage processing and the thumbnail image display processing have been completed up to the last frame. If the processing has not been completed, the process returns to step 303, and the above-described processing is performed on the next frame. . In the present embodiment, although there is no particular reference to compression / expansion of an image, compression can be applied for the purpose of saving memory.

When the storage processing and the thumbnail image display processing are completed up to the last frame, the feeding of the film 21 is stopped at step 309, and the thumbnail images of all the frames of the film 21 are stored in the large capacity memory 28 at the next step 310. At step 311, reproduction of information magnetically recorded on the film 21 is started by a reproducing device (not shown). At step 312, the film feed control circuit 23 and the film feed mechanism 22 are started.
Starts the rewinding of the film 21. Step 3
In step 13, the magnetic information for each frame is reproduced, and the subsequent step 31
The magnetic information of each frame reproduced in step 4 is added to the image information of each frame stored in the large capacity memory 28.

In step 313, it is confirmed whether or not the reproduction process of the magnetic information has been completed and the film 21 has been rewound to the cartridge.
Returning to step 13, the magnetic information of the next frame is reproduced. When the reproduction of the magnetic information of all the frames is completed and the film 21 is rewound into the cartridge, the image storing operation is completed.

FIG. 3 is a flowchart showing the image display processing of a specific frame. In step 411, it is confirmed whether or not there is an instruction to display an image of a specific frame by an operation input device (not shown). When there is an instruction to display an image of a specific frame, the process proceeds to step 412, where the image number of the frame to be displayed is specified.
At step 413, an image of a specific frame is read from the large-capacity memory 28, and then stored at the image memory 27 at step 414. In step 415, the image of the specific frame is sent from the image memory 27 to the image display circuit 29, and is displayed on the display device 30 on one screen.

As described above, an image is taken from a film, stored in an image memory functioning as a video RAM, and transferred from the image memory to a large-capacity memory and stored. Therefore, a simple configuration is possible without using a personal computer. Thus, a large amount of image information can be captured, stored, and displayed.

Second Embodiment of the Invention A second embodiment in which a loaded film cartridge is identified and a thumbnail image is immediately displayed for a film cartridge in which an image is already stored in a large-capacity memory. A second embodiment will be described.

FIG. 4 shows the configuration of the second embodiment. Note that the same reference numerals are given to the same devices as the devices of the first embodiment shown in FIG. 1, and the description will focus on the differences.
The second embodiment is obtained by adding a photo interrupter 31 as a film cartridge identification unit to the first embodiment. Film identification information is optically recorded on the film 21, and the photo interrupter 31 detects the film identification information. The method of identifying a film cartridge is not limited to this embodiment. For example, identification information recorded in a cartridge by a barcode may be detected by a photo reflector.

FIG. 5 is a flowchart showing an image storing operation according to the second embodiment. In step 701, the feeding of the film 21 is started by the film feeding control circuit 23 and the film feeding mechanism 22, and in the following step 702, the photo interrupter 31 detects the identification information of the film cartridge. In step 703, the image of the loaded film cartridge is stored in the large-capacity memory 28.
Check if it is stored in. If the image of the loaded film has already been stored in the mass memory 28, the process proceeds to step 704;
Proceed to 7.

If the image of the loaded film cartridge is already stored in the large-capacity memory 28, the thumbnail image of this film is read from the large-capacity memory 28 in step 704 and stored in the image memory 27 in step 705. . Then, in step 706, the thumbnail image is sent from the image memory 27 to the image display circuit 29, and the thumbnail image is displayed on the display device 30.

If the image information of the loaded film cartridge is not stored in the large-capacity memory 28, in steps 707 to 720, step 302 of FIG.
