Abstract

A two-dimensional image can be displayed in a desired position, a desired aspect ratio of the display image can be maintained, and such an elemental image array as to maximize an interpolating effect can be produced. A producing method of an elemental image array for three-dimensional image display includes: converting the resolution of the two-dimensional image into substantially the same resolution of a three-dimensional image display device; obtaining multipoint images by shifting the position to sample the two-dimensional image after the resolution conversion at regular intervals in the horizontal direction; and rearranging the multipoint images according to the positional relationship between exit pupils and projecting directions.

Description

technical field [0001] The present invention relates to methods and apparatus for generating elemental image arrays for three-dimensional image display. Background technique [0002] Disparity information recognizable by an observer who moves in the horizontal direction and observes a two-dimensional image facing the observer relates only to the horizontal movement of the two-dimensional image. If the two-dimensional image is positioned in front of the viewpoint, the two-dimensional image moves in the opposite direction to the observer. If the two-dimensional image is located behind the viewpoint, the two-dimensional image moves in the same direction as the observer. Therefore, in the case where a two-dimensional image is to be displayed on a horizontal parallax type three-dimensional image display device, an image obtained by moving the two-dimensional image (hereinafter referred to as an original image) can be used as a viewpoint image (for example, Japanese Patent Laid-O...
