Next, the operation of dividing and displaying the thumbnail images of the digital camera (operation example 1 and operation example 2) will be described. <Operation Example 1> An operation example 1 will be described with reference to a flowchart shown in FIG. 6 and a display example shown in FIG. FIG. 6 is a flowchart showing a processing procedure of the first operation example, and FIG. 7 shows a display example of a divided screen of the first operation example.

First, when the division display of thumbnail images is instructed by the “division display instruction” key of the operation unit 14 (step S 1), the total number of image files stored in the memory card 9 (step S 1). The total number of image data and the total number of thumbnail images) N are checked (step S).
2). Specifically, the CPU 13 searches for an entry in the directory entry area 94 of the memory card 9 and performs the search. If "NO" in the step S1, the process returns to the start.

Then, the CPU 13 stores the total number N of the obtained image files in the total image number register R1 (step S3). Then, the CPU 13 sets the number of divisions D of the thumbnail image designated by the “specify the number of divisions” key of the operation unit.
Is stored in the division number register R2 (step S4).
Subsequently, the CPU 13 determines the total number N of image data files.
The total page number L obtained by calculating the / division number D is stored in the total page number register R3 (step S5). However, if there is a remainder in the calculation of the total number N of image files / the number D of divisions, a value obtained by adding +1 to the quotient is set as the total number L of pages.
For example, if the total number N of image files is 50 and the number of divisions D is 4
In this case, the total number of pages L is 13 (quotient 12 + 1).

Then, the CPU 13 stores the page number P designated by the "page number designation" key of the operation unit 14 in the current page number register R4 (step S6). On the other hand, to obtain the data of the current page number register R4,
The number of pages on which the thumbnail images are displayed can be calculated by the same calculation as the above. Using the above example, if the 30th thumbnail image is selected, and the number of divisions D is 4, the quotient is 7 and the remainder is 2 when 30/4, the quotient is +1 and the current page is 8. The number, and the 30th thumbnail image is displayed on page 8.

Next, the CPU 13 reads out the thumbnail images of the designated page number P from the memory card 9 by the number of divisions D and displays them on the LCD 10 via the digital signal processing circuit 6 by the number of divisions (step). S7).
Then, the CPU 13 displays the “page display ON” of the operation unit 14.
If page display ON is designated by the "/ OFF" key (step S8), "currently displayed page number P / total number of pages L" is displayed at the lower right of the screen (step S9). Note that the CPU 13 thins out some of the pixels of the thumbnail images stored in the memory card 9 at certain intervals in order to display thumbnail images of a size corresponding to the number of divisions. In the above step S8, "page display ON"
Is not specified, that is, if “NO”, the process skips step S9 and shifts to step S10.

When the "page feed" key of the operation unit 14 is operated (step S).
10) The current page number P of the current page number register R4 is incremented by "1" (step S1).
1) Display the split screen of the subsequent page and increment the displayed current page number P by "1" (step S12). In the above step S10, "page feed"
If no operation has been performed, that is, if “NO”, steps S11 and S12 are skipped and the process proceeds to step S13.

When the "page return" key of the operation unit 14 is operated (step S1).
3) The current page number P of the current page number register R4 is decremented by "1" (step S14).
The divided screen of the previous page is displayed, and the displayed current page number P is decremented by "1" (step S1).
5). If the "page return" operation is not performed in step S13, that is, if "NO", steps S14 and S15 are skipped and step S16 is performed.
Move to

When the last page is displayed and the page feed is designated by the "page feed" key, the first page is displayed. When the first page is displayed and the page return is designated by the “page return” key, the last page is displayed. That is, the first page and the last page are displayed as subsequent pages.

When the end of the split display is instructed by the "split display instruction" key of the operation unit 14 (step S16), the CPU 13 ends the process,
If the end of the split display has not been instructed, step S
Move to 10.

The display example shown in FIG. 7 shows the total number N of image data.
= 72, the case where the number of divisions D = 9 is designated by the “designation of number of divisions” key, and the total number of pages L = 8. In particular, FIG. 7A shows eight pages, and FIG. 7B shows one page. When the “page forward” key is operated while the eight pages (last page) shown in FIG. 7A are displayed, one page (first page) shown in FIG. 7B is displayed. . FIG. 7B
When the "page return" key is operated when one page (first page) shown in FIG. 7 is displayed, eight pages (final page) shown in FIG. 7A are displayed.

In FIGS. 7A and 7B, a display example in which “the number of pages currently displayed / the total number of pages” is displayed using numerals at the lower right of the screen is shown. The invention is not limited to this. As another page display method, for example, it may be displayed at another position on the screen using an indicator. More specifically, a display method of arranging a number of boxes corresponding to the total number of pages L continuously on the screen and making a box corresponding to the currently displayed page stand out (for example, by adding a shadow) is used. You may.

As described above, according to the first operation example,
When displaying thumbnail images of the number of divisions D designated by the “designation of the number of divisions” key, the total number N of image data files (image data, thumbnail images) recorded on the memory card 9 is determined by the designated number of divisions D. The divided number is defined as a total page L, and the total page number L and the page number P of the currently displayed screen are displayed. Therefore, when a plurality of thumbnail images are displayed on one screen, The operator can easily determine what page the displayed screen is.

<Operation Example 2> First, an operation example 2 will be described with reference to a flowchart shown in FIG. 8 and a display example shown in FIG. FIG. 8 is a flowchart showing a processing procedure of the operation example 2, and FIG. 9 shows a display example of a divided screen of the operation example 2. In the display example shown in FIG. 9, a file number and a display position number are added to each thumbnail image. In the operation example 2, by operating the cursor keys of the operation unit 14, one of the divided thumbnail images can be displayed as a cursor (identification display).

First, when the division display of a thumbnail image is instructed by the “division display instruction” key of the operation unit 14 (step S 21), the CPU 13
The total number of image files (total number of image data, total number of thumbnail images) N stored in the file is checked (step S2).
2). Specifically, the CPU 13 searches for an entry in the directory entry area 94 of the memory card 9 and performs the search. If "NO" in the step S21, the process returns to the start.

Then, the CPU 13 stores the total number N of the obtained image data files in the total image number register R1 (step S23). Then, the CPU 13 stores the division number D of the thumbnail image specified by the “division number” key of the operation unit in the division number register R2 (Step S).
24). Subsequently, the CPU 13 stores the total number of pages L obtained by calculating the total number of image files N / the number of divisions D in the total page number register R3 (step S25).
However, if there is a surplus in the calculation of the total number N of image data files / the number D of divisions, a value obtained by adding +1 to the quotient is set as the total page number L.

Then, the CPU 13 stores the page number P designated by the "page number designation" key of the operation unit 14 in the current page number register R4 (step S26). Then, the CPU 13 reads out the thumbnail images of the designated page number P from the memory card 9 by the number of divisions D and transmits the thumbnail images by the digital signal processing circuit 6 by the number of divisions.
It is displayed on the CD 10 (step S27). And CP
If page display ON is designated by the “page display ON / OFF” key of the operation unit 14 (step S28), U13 displays “the currently displayed page number P / the total number of pages L” on the right side of the screen. It is displayed below (step 29). Note that the CPU 13 thins out some of the pixels of the thumbnail images stored in the memory card 9 at certain intervals in order to display thumbnail images of a size corresponding to the number of divisions. On the other hand, if the page display ON is not designated by the “page display ON / OFF” key, the process skips step S29 and shifts to step S30.

When the number of divisions D is changed by the "division number designation" key of the operation unit 14 (step S30), the CPU 13 sets the number of divisions instructed to change.
In addition to displaying the divided screen of the page including the thumbnail image currently displayed by the cursor (step S3
1) The "currently displayed page number P / total number of pages L" is changed and displayed (step S32). On the other hand, if it is determined in step S30 that the number D of divided displays has not been changed, steps S31 and S32 are performed.
And skips to step S33.

When the end of the divided display is instructed by the "divided display instruction" key of the operation unit 14 (step S33), the CPU 13 terminates the process and instructs the end of the divided display. If not, the process moves to step S30.

The display example shown in FIG. 9 shows a case where a change instruction is made between the four-split display and the nine-split display by the "division number designation" key. In the 4-split screen (currently displayed page number 3, total page number 8) shown in FIG.
When the cursor is displayed on the upper left thumbnail image (image of the personal computer), "Specify the number of divisions"
When the number of divisions is changed to “9” by the key, as shown in FIG. 9B, a nine-split screen of the page including the thumbnail image currently displayed by the cursor is displayed, and the cursor is displayed. The thumbnail image is located at the lower right of the screen (display position number 9 on the divided screen). Then, in the lower right of the screen, the changed “currently displayed page number 1 /
A total page number of 4 "is displayed. In this operation example, it is possible to display the file number and the display position number of the thumbnail image, or any one of them.

In the second operation example, the CPU 13
First, the file number C of the thumbnail image (image of the personal computer, file number 9) designated by the cursor is stored in the directory entry area 94 of the memory card 9.
From the file name data (see FIG. 4). The file number C of each image data file is a subsequent file number for storing image data in the memory card 9.

Next, the CPU 13 obtains the new “file number C−1 / changed divided display number D” to obtain the page number currently displayed and the display position number of the thumbnail image.
Is calculated. As a result of the calculation, “quotient + 1” is set to “currently displayed page number”, and “remainder + 1” is set to the display position number of the thumbnail image displayed by the cursor on the divided screen.

The above calculation will be described in detail with reference to a screen change display example from FIG. 9A to FIG. 9B. When the number of divided thumbnail images is changed from 4 to 9, the file number 9 of the thumbnail image (image of the personal computer) displayed by the cursor is subtracted from 1 (9-1 = 1).
8).

Then, when 8 is divided by the changed divided display number, that is, 9 ((9-1) / 9), the quotient is 0 and the remainder 8 is obtained. As a result of the calculation, “quotient + 1”, that is, “0 + 1 = 1” becomes the currently displayed page number, and “remainder + 1”, ie, “8 + 1 = 9”, of the thumbnail image (image of the personal computer) displayed by the cursor. This is the display position number on the split screen. Further, the total number of pages is 4 by the above-described calculation.

Further, the above operation is performed by comparing FIG.
A description will be given using an embodiment in which the screen is changed to (A). When the number of divided thumbnail images is changed from 4 to 9, the file number 9 of the thumbnail image (image of the personal computer) displayed by the cursor is subtracted from 1 (9-1 = 1).
8). When 8 is divided by the change division display number, that is, 4 ((9-
1) / 4), the quotient is 2, and the remainder is 0.
