[0006]

FIG. 1 shows the configuration of an embodiment for displaying an image of a developed photographic film. 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. C
The PU 26 sequentially stores the transferred images in the image memory 27.

On the film 21, a magnetic recording section for magnetically recording various information is formed, and image processing information described later for each frame is recorded. The recording medium for various information such as image processing information is not limited to the magnetic recording unit on the film, but may be a magnetic recording unit formed on a film cartridge, for example.

The CPU 26 sends the image of one frame transferred from the image processing circuit 25 to the image display circuit 28, and performs one-screen display on the display device 29 for displaying one frame of image on one screen. The CPU 26 also reads a plurality of images stored in the image memory 27, converts them into thumbnail images, transfers them to the image display circuit 28, and displays a list of images of a plurality of frames on the display device 29, that is, performs thumbnail image display. .
Here, in the thumbnail image display, an image of a plurality of frames is displayed in one screen, so that the image of each frame is smaller and coarser than the image displayed in the single screen.

When the image processing operation input device 30 performs processing such as zoom (enlargement / reduction), shift (movement), and rotation while viewing the image of a certain frame displayed on the display device 29 on one screen, the CPU 26 causes The image stored in the image memory 27 is updated to a processed image, and the information processing device 31 records the image processing information in the magnetic recording unit of the frame. Thereafter, when there is a request to display a thumbnail image again, the information reproducing device 32 reproduces the processing information magnetically recorded on each frame, processes the image according to the image processing information, and displays the thumbnail image.

Next, the operation of the embodiment will be described with reference to the flowcharts of FIGS. FIG. 2 is a flowchart showing a thumbnail image display process. Step 301
In step (2), film feeding is started by the film feeding control circuit 23 and the film feeding mechanism 22, and the first frame is set at a predetermined image pickup position of the CCD image pickup circuit 24 in the subsequent step 302. In step 303, the CCD imaging circuit 24
, And is processed by the image processing circuit 25 to be converted into digital image data. In step 304, the image transferred from the image processing circuit 25 is stored in the image memory 27.

In step 305, the image processing information of the first frame magnetically recorded on the film 21 is reproduced by the information reproducing device 32 and stored in the internal memory of the CPU 26. In the following step 306, while capturing and storing the image up to the last frame, it is confirmed whether or not the image processing information has been reproduced,
If not completed, the flow returns to step 303 to input the image of the next frame and reproduce the image processing information. If the input of the image and the reproduction of the image processing information have been completed up to the last frame, step 30 is executed.
7, the plurality of images stored in the image memory 27 are read and converted into thumbnail images, and the image display circuit 2
8 to display a thumbnail image on the display device 29.
At this time, for the frame on which the image processing information is recorded,
The image is processed according to the processing information, converted to a thumbnail image, and displayed.

FIG. 3 is a flowchart showing one-screen display processing of an image of each frame. In step 401, a frame feed switch (not shown) is operated to check whether or not a frame feed instruction has been issued.
Proceed to 2. In step 402, one frame of film is fed by the film feeding control circuit 23 and the film feeding mechanism 22, and the next frame is set at a predetermined imaging position. In the following step 403, the image of the frame set at the image capturing position is captured by the CCD image capturing circuit 24, processed by the image processing circuit 25, and converted into digital image data. In step 404, the image transferred from the image processing circuit 25 is sent to the image display circuit 28 and displayed on the display device 29 on one screen.

FIG. 4 is a flowchart showing the processing for processing an image displayed on one screen. In step 501,
It is determined whether or not the zoom switch of the image processing operation input device 30 has been operated.
Proceeding to step 02, the image is zoomed according to the operation input. In step 503, the image of the frame stored in the image memory 27 is updated to an image enlarged or reduced by the zoom processing.

In step 504, it is confirmed whether or not the screen rotation switch of the image processing operation input device 30 has been operated, and if it has been operated, the process proceeds to step 505.
The image is rotated according to the operation input. Step 5
In step 06, the image of the frame stored in the image memory 27 is updated to the image rotated by the rotation process.

In step 507, it is confirmed whether or not the screen shift switch of the image processing operation input device 30 has been operated. If the switch has been operated, the flow advances to step 508 to shift the image in accordance with the operation input. The shift processing is to shift the center of the image in the screen.
In step 509, the image of the frame stored in the image memory 27 is updated to the image moved by the shift processing.

In step 510, the processing information such as the zoom (enlargement / reduction), shift (movement), and rotation of the image performed by the image processing operation input device 30 is transmitted to the information recording device 31 by the magnetic recording unit To record.

As described above, when processing such as enlargement / reduction, rotation, and movement is performed on an image displayed on one screen on the display device, the image processing information is magnetically recorded on the film, and then the thumbnail of the film is displayed. When displaying an image, the image is processed according to the image processing information of each frame, and then a thumbnail image is displayed. Therefore, the processed contents of the image are reflected in the thumbnail image display, and the thumbnail image is displayed in an image form desired by the user for each frame.

In the configuration of the above embodiment of the present invention,
The CCD imaging circuit 24 and the image processing circuit 25 serve as image input means, the information reproducing device 32 serves as information reproducing means, and the CPU 2
6, an image conversion means, an image display circuit 26 and a display device 27 constitute an image display means, an image processing operation input device 30 constitutes an image processing operation means, and an information recording device 31 constitutes an information recording means.
