摘要

A viewing direction image data generator which generates n (n is an integer of 2 or more) pieces of viewing direction image data corresponding to n viewing direction images that generates a directional display image. Each of the viewing direction images is composed of a plurality of pixels arranged in a matrix. The directional display image is configured by arranging the plurality of pixel elements in a matrix in a row direction and a column direction. The directional display image is divided into a plurality of pixel blocks, and, if each of the pixel blocks is composed of (3·n) pixel elements which are set such that a set of three-color pixel elements of each of the viewing direction images is included, image data of which the data amount is reduced to 1/n is generated as the n pieces of viewing direction image data.
