It is assumed that the images for the frames are simultaneously displayed on one screen of the display device 5.

FIG. 3 shows an example of the display screen of the display device 5 when the proof display is set. Proof display is performed by generating a reduced image of 9 frames and displaying the reduced image of 9 frames on the display screen of the display device 5. Therefore, first, a method of creating a reduced image will be described. In this embodiment, it is assumed that each reduced image shown in FIG. 3 is generated by setting the size in the vertical direction and the size in the horizontal direction to 1/8 of the size of the original image. Image reduction processing is performed by, for example, thinning processing. As shown in FIG. 6, by thinning out image data for 7 pixels out of 8 pixels in the horizontal and vertical directions, reduced image data representing a reduced image with a reduction rate of 1/8 in the vertical and horizontal directions can be obtained. In addition to this, there is averaging processing as reduction processing. This is to calculate an average value of image data of adjacent 8 pixels × 8 pixels in the original image, and use this average value as image data of 1 pixel in the reduced image (when the reduction ratio is 1/8). In any case, transfer of image data from the RGB data memory 54 to the display memory 55 and image reduction processing are executed by the GSP 57.

When the proof display shown in FIG. 3 is performed,
The reduced images displayed on the display device 5 are all in the horizontal direction (the horizontal direction of the reduced image is longer than the vertical direction).
Therefore, even when the subject is photographed with the digital electronic still camera held vertically, the reduced images displayed on the display device 5 are arranged horizontally (frame numbers "002" and "005"). This makes the proof display image difficult to see. Therefore, in the image processing device 7 shown in FIG. 1, a desired reduced image of the proof display image can be changed in its display direction from the horizontal direction to the vertical direction as shown by a chain line in FIG. The proof display image after changing the desired reduced image from the horizontal direction to the vertical direction is shown in FIG.
Is shown in In FIG. 4, each reduced image is displayed in the same state as that of the subject at the time of shooting, so that the proof display is easy to see.

Further, the image processing apparatus 7 shown in FIG. 1 can cause the high-definition printer 4 to print the proof-displayed image. A proof printed print is shown in FIG. When performing proof printing, the image processing apparatus 7 can select and print only a desired image and omit unnecessary unnecessary images. FIG. 5 is a proof-printed print containing only the required reduced image.

7 and 8 are flow charts showing the procedure of such proof display and proof printing.

When the proof display setting key 96 is pressed, the process of proof display and proof printing is started. When this process starts, the RAM (RAM 59 and 63 and memories 54 and 5 included in the image processing apparatus 7
5) is cleared and the display screen of the display device 5 is cleared (step 101). Subsequently, the media selection key 72 is set by the user as to which of the recording mediums of the memory card 2 and the optical disk 3 the image data recorded on is read out and whether the image represented by the image data is proof-displayed or proof-printed. Is determined based on the command (step 102). Media selection key 72
When the memory card 2 is selected by, the compressed image data stored in the memory card 2 is read out, and Y / C
It is given to the frame memory 52 and temporarily stored (step 103). When the optical disk 3 is selected by the media selection key 72, the compressed image data stored in the optical disk 3 is read out, given to the Y / C frame memory 52 and temporarily stored (step 104).

In any case, the compressed image data read from the memory card 2 or the optical disk 3 is given to the Y / C frame memory 52 and temporarily stored therein. The compressed image data is read out from the Y / C frame memory 52 and given to the compression / expansion processing circuit 51 to be subjected to data expansion (step 105). Image data that has undergone data expansion is Y / C
The RGB data is supplied to the RGB conversion circuit 53, and the luminance data Y and the color difference data C are converted into the three primary color data RGB. The three primary color data RGB are temporarily stored in the RGB data memory 54 and given to the work RAM 59 for storage.

The image reduction processing is performed on the one-frame image data RGB of three primary colors stored in the work RAM 59 under the control of the GSP 57 (step 106). The reduced image data representing the reduced image is given to the display memory 55 and stored in a predetermined area (step 107). When the compression image data expansion processing and the image data reduction processing are performed on the image for 9 frames, the reduced image for 9 frames is proof-displayed as shown in FIG. 3 together with the identification number of the reduced image (step 108). ).

As a result of the proof display as shown in FIG. 3, when the proof display image includes a reduced image to be displayed in the vertical direction, the rotary key 94 included in the operation panel 70 is pressed (YES in step 109). ). When the rotation key 94 is pressed, the reduced image to be rotated is specified by specifying the identification number using the ten keys 71 (step 11).
0). As a result, the image data is rotated so that the designated reduced image is rotated 90 ° to the right (step 111). This rotation processing can be realized by performing an addressing operation such that each pixel of the reduced image is rotated 90 ° with the center of the reduced image as the origin. Depending on how the digital electronic still camera is held at the time of shooting, rotating the image may cause the reduced image to rotate upside down. In such a case, the rotation process should be further 2
By repeating this, the reduced image is displayed in the same direction as the direction of the subject at the time of shooting. In any case, by rotating a desired reduced image, it is displayed in a direction that matches the direction of the subject at the time of shooting, as shown in FIG. An easy-to-see proof display can be realized.

Subsequently, it is determined whether or not to print the proof-displayed screen (step 112). If the print key 89 is pressed within the fixed time, it is determined that the proof printing is performed (YES in step 112). The image processing apparatus 7 shown in FIG. 1 can proof-print an image composed of a desired reduced image among a plurality of reduced images displayed in the proof display.

When the composition does not change much like the reduced images indicated by the identification numbers “003” and “004” in FIG. 4, or when the images are reduced like the reduced images indicated by the identification numbers “005” and “006”. Memory card 2 if you can see only one of them in almost the same case
Alternatively, the confirmation of the image represented by the image data recorded on the optical disc 3 can be achieved. Therefore, an identification number representing an unnecessary image is designated by the ten keys 71 and the delete key 77 is pressed. As a result, the image data representing the reduced image having the identification number designated by the ten keys 71 is erased from the display memory 55 and erased from the proof display screen (step 113). When the print key 89 is pressed again, the proof display screen displayed on the display device 5 is printed, and as shown in FIG. 5, it is possible to obtain a print in which only the desired image is displayed in the easy-to-see direction.
