Apparatus, method, and program for image display
Backup of image data sets is carried out with ease. For this purpose, the image data sets are stored in image storage means. The image storage means may comprise a plurality of recording media or an external apparatus. When the image data sets stored in the image storage means are displayed, a degree of security is calculated for the image data sets according to reliability of backup locations of the image data sets and the number of the backup locations, for example. The degree of security is displayed in a visually perceptible manner. For example, in the case where the degree is low for one of the image data sets, a red or yellow frame is added to the corresponding image according to the degree of security thereof.
