Abstract: A disclosed image display apparatus for displaying multiple images on a single screen includes a magnification unit configured to, in response to a zooming operation on the screen, magnify distances between centroids of first group images included in the multiple images and magnify the first group images; and a display control unit configured to display in a space of the magnified distances one or more images different from the multiple images. A magnification rate of the distances between the centroids has a nonlinear relationship to a magnification rate of the first group images, and within an extent of the nonlinear relationship, the magnification rate of the distances between the centroids has a predetermined range in which the magnification rate of the first group images is larger than the magnification rate of the distances between the centroids.

Abstract: An attribute determining unit determines an attribute of image data of an image.

The acquired coded data used for the display is decoded/extended, and the image is displayed on a display unit. A user inputs a direction for saving the image displayed on the display unit via a user interface unit. Coded data for the saving of the image directed by the user is acquired from the image data source, such as by additionally acquiring coded data equivalent to a difference between the coded data for the saving and the coded data used for the display from the image data source, and synthesizing the coded data for the saving from the additionally acquired coded data and the coded data used for the display. The acquired coded data for the saving is saved in a storage unit.
