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.
