FIG. 2 shows an image being exposed on the film 2. 31 indicates the entire area of the image exposed on the film 2, and 32 indicates the area printed in the lab. As is clear from the figure, the print range 32 is a range slightly smaller than the entire range 31. On the other hand, reference numeral 33 denotes a print range when the panorama size is designated. The panorama size designation information is recorded as the above-described magnetic information of the film or is recorded as optical information of the film.

FIG. 3 shows a print example of a film image.
(A) is a normal size print of the twelfth frame shown in FIG.
That is, a print in a normal print range is shown, and (b)
Indicates a panoramic size print of the thirteenth frame shown in FIG.

FIG. 4 shows a video example of a film image in the panoramic range of FIG. 2 by a conventional film image viewing apparatus.
(A) shows an image when an image is displayed at a standard position,
(B) shows an image when an image is displayed at a position shifted in the vertical direction, and (c) shows an image when an image is displayed at a position shifted in the horizontal direction. When the imaging camera is shifted in the Y direction as shown in (b), since the upper and lower masks do not move regardless of the movement of the imaging camera, the upper part of the film image that was not seen before the movement is newly visible. However, the lower part of the film image that was visible before the movement is hidden by the mask and becomes invisible. Also, since the width of the film image is displayed to fill the width of the television screen, if the imaging camera is shifted in the X direction as shown in FIG. When the moving amount is large, a portion other than the film image is projected.

FIG. 5 shows a video example of a film image in the panoramic range of FIG. 2 according to this embodiment. (A) shows an image when the image is displayed at the standard position, (b) shows an image when the image is displayed at a position shifted in the vertical direction,
(C) shows an image when an image is displayed at a position shifted in the horizontal direction. When the imaging camera is shifted in the Y-direction as shown in (b), the image of the film image moves downward on the display screen. At this time, the mask at the top of the screen displayed on the opposite side to the moving direction of the image does not change regardless of the movement of the image, and the mask at the bottom of the screen displayed on the side of the moving direction of the image depends on the moving amount of the image. The amount of the mask, that is, the width of the mask is reduced. Therefore, the upper part (the part above the broken line in the figure) of the film image that was not seen before the movement of the video is newly visible. In addition, the width of the mask at the lower portion of the film image that was seen before the movement of the image is reduced in accordance with the amount of movement of the image in the downward direction of the screen, so that the image is not hidden by the mask. As a result, the display range of the film image is widened as compared with the standard time (a).

Further, as shown in FIG.
When the image is shifted in the + direction, the image of the film image moves rightward on the display screen. However, since the width of the film image is displayed to fill the width of the TV screen,
When the imaging camera is shifted in the X + direction, the left part of the film image (the part to the left of the broken line in the drawing) that was not visible before moving the image is newly visible, but the film that was visible before moving the image is newly visible. The right part of the image disappears at the right edge of the screen.
When the moving amount is large, a portion other than the film image is displayed on the left end of the display screen. In other words, in this case, as the image moves, the image becomes invisible on the right side of the display screen, and only becomes newly visible on the left side.
The display range of the film image does not change. In addition, when the moving amount of the video is increased, the display range of the film image is reduced.

In the example of FIG. 5 described above, a video image of a film image taken with the camera held at the normal position (horizontal position) has been described as an example. However, when projecting a film image shot in a vertical position, the horizontal width of the film image is displayed to fill the entire vertical width of the display screen unless the image of the film image is rotated, and the mask is displayed on the left and right sides of the display screen. In this case, when the imaging camera is moved in the Y direction, the image of the film image moves right and left on the display screen, and the width of the mask in the image moving direction becomes narrower as the image moves, and the image becomes The display range is widened without being hidden behind the mask. However, when the imaging camera is moved in the X direction, the mask is not displayed because the horizontal width of the film image is displayed to fill the vertical width of the display screen.

FIG. 6 is a flow chart showing the processing when loading a film. When the film cartridge 1 is loaded into the film image viewing apparatus, first, the film is fed and the magnetic data is read. This magnetic data contains information on the print format. Mask display is performed according to the print format information. When the film cartridge is loaded, the XY movement position of the imaging camera is set to the default.

When the cartridge 1 is loaded in step 1001, the flow advances to step 1002 to feed the film 2 in the winding direction. At step 1003, information magnetically recorded on the film 2 during film feeding is read and stored in the memory 24. The magnetic information is read while the film 2 is wound up to the last frame, and when the reading of the magnetic information of the last frame is completed, the film feeding is stopped in step 1005. Next, in steps 1006 to 1008, the film 2 is rewound, and the first frame is set in the image area 26.

If it is not the last frame, the film 2 is wound up by one frame in step 1203, and the mask information of the next frame is read from the memory 24 in step 1204. In step 1205, it is checked whether or not the position (lateral position) of the imaging camera in the X direction is the reference position (X = 0). In step 1206, the process shown in FIG. 10 is executed to set the X position as the reference position.

Similarly, in step 1207, it is confirmed whether the position (vertical position) of the imaging camera in the Y direction (vertical position) is a reference position (Y = 0). If not the reference position, step 1
In step 208, the processing shown in FIG. 11 is executed to set the Y position as the reference position. In step 1209, a film image of the frame set in the image area 26 is captured, a video signal is output, and the video signal is displayed on a display device such as a television. In step 1210, a mask is displayed on the display screen according to the mask information of the frame.

FIG. 9 is a flowchart showing the one-frame rewinding process. When one frame rewind operation is performed, one frame is returned, and then the image of the next frame is displayed on the display device. At this time, the mask is displayed according to the mask information magnetically recorded on the film. When one frame has been rewound, the X and Y positions of the imaging camera are set to default positions. When the rewind switch of the operation switch 23 is operated in step 1301, the flow advances to step 1302 to check whether the frame currently set in the image area 26 is the first frame. In the case of the first frame, no rewinding is performed, and step 130
Go to 9.

If it is not the first frame, the film 2 is rewound by one frame at step 1303, and the mask information of the next frame is read from the memory 24 at step 1304. In step 1305, it is checked whether the position (lateral position) of the imaging camera in the X direction is the reference position (X = 0). If it is the reference position, there is no need for adjustment, so the process proceeds to step 1307. In step 1306, the process shown in FIG. 10 is executed to set the X position as the reference position.

Similarly, in step 1307, it is confirmed whether the position (vertical position) of the imaging camera in the Y direction (vertical position) is a reference position (Y = 0). If not the reference position, step 1
At 308, the process shown in FIG. 11 is executed to set the Y position as the reference position. In step 1309, a film image of the frame set in the image area 26 is captured, a video signal is output, and the video signal is displayed on a display device such as a television. In step 1310, a mask is displayed on the display screen according to the mask information of the frame.
