Abstract
Provided is an image generation technology capable of suppressing unpleasantness associated with fluctuation in image quality caused by the viewer's viewpoint movement. A synthesis ratio determination unit of an image generation apparatus includes: an image quality evaluation index calculation unit that generates a synthesis image Jfrom an observation viewpoint image Iand an intermediate viewpoint image I, and a synthesis image Jfrom an observation viewpoint image Iand an intermediate viewpoint image I, for a plurality of synthesis ratios, calculates an image quality evaluation index in an observation viewpoint V, an image quality evaluation index in an intermediate viewpoint V, and an image quality evaluation index in an observation viewpoint Vby using the synthesis images Jand J, and calculates a variation v of an image quality evaluation index by using the image quality evaluation index in the observation viewpoint V, the image quality evaluation index in the intermediate viewpoint V, and the image quality evaluation index in the observation viewpoint V; and an image quality evaluation index comparison unit that determines a synthesis ratio A based on the variation v of the image quality evaluation index.
