Abstract
An image display unit has a display region with a higher resolution than a number of pixels of an image. A base information storage unit stores viewing position information of a viewer and size information of the display region. A wide-angle transformation unit calculates a central area including a viewing center of the viewer of the display region using the viewing position information and the size information, divides the image into a first pixel area corresponding to the central area and a second pixel area corresponding to a peripheral area other than the central area, and transforms the first pixel area and the second pixel area by magnifying. A magnification ratio of the first pixel area is less than a magnification ratio of the second pixel area. The image display unit displays an image including the transformed first pixel area and the transformed second pixel area.
