摘要： The present invention makes it possible to rapidly obtain a two-dimensional image which is not discontinuous and does not include distortion from three-dimensional image display data. When a two-dimensional image is displayed, a viewing point within a viewing zone is assumed, and a parallax image displayed on pixels positioned at a position where a line connecting the viewing point and an exit pupil, and the display unit cross each other or positioned in the vicinity thereof in a state that a three-dimensional image is displayed is developed and displayed within a corresponding elemental image including the pixels.
