<p>PROBLEM TO BE SOLVED: To generate image data equivalent to light field data photographed by a light field camera by computer graphics.SOLUTION: A front clip surface 102, a lens array surface 103, and a rear clip surface 104 are sequentially set in the direction of a scene to be a drawing object from a view point 101. Then, the tracking direction of a light beam is changed in accordance with the arrangement of a plurality of small regions (lens surfaces) constituting the lens array surface 103 in the front clip surface 102. Data equivalent to light field data is obtained by tracking the light beam in the changed tracking direction to draw a scene between the lens array surface 103 and the rear clip surface 104.</p> |
