The reduced image display area 502 is composed of a plurality of reduced images. The actual image data is reduced at a predetermined magnification, and the reduced image is viewed to determine which file is the image data file. Is instantaneously recognized. The file name of the image data file of the reduced image is also displayed below the reduced image.

Instead of specifying a file name in the file name display area 501, a desired image can be selected by moving a cursor to the reduced image itself and clicking a button such as a mouse 212. In this case, the operator can quickly and easily select a desired image data file based on the reduced image even if the file name is not accurately stored.

If a predetermined keyword, for example, a keyword such as "person", "landscape" or "business" or "personal" is added to each image data file and registered, the keyword is based on the keyword. The display order of the reduced images can be changed and displayed. As a result, even if the number of registered image data files increases, it is possible to search for a desired image data file at high speed by rearranging by keyword.

In the display example of FIG. 5, the number of reduced images to be displayed is set to be 24 in 8 × 3 rows. However, depending on the resolution of the display device, the content of the displayed image, or the search method, it is different. It is possible to change the display arrangement and the number of displayed reduced images.

The selected image display area 503 is an area for displaying the image of the image data file selected from the file name in the file name display area 501 or the image data file selected from the thumbnail in the reduced image display area 502. As the display format, a standard display in which the image is displayed in a standard size, an entire display in which the image is enlarged or reduced in order to display the entire image, and a magnification display in which the operator displays the image at a desired magnification can be considered. The magnification is designated by inputting the percentage of the magnification, and the magnification becomes equal at 100%. When a numerical value smaller than that is input, the magnification is reduced, and when a larger numerical value is input, the magnification is enlarged.

In the selected image display area 503, by specifying a command from a predetermined menu or by double-clicking the image itself, a file name display area 501 and a reduced image display area 502 are displayed on the entire display screen. The currently displayed image can be displayed so as to be hidden. As a result, the editing work can be performed more efficiently. This is particularly effective for large images. When the editing processing is completed, it is possible to return to the original image area by specifying a command from a predetermined menu or by double-clicking the image itself again. At this time, the file name display area 501
And the reduced image display area 502 is displayed again.
