PURPOSE: To generate images for the right and left eyes which an observer can blend into a stereoscopic image without feeling a burden on his eyes by investigating region for fixing the range of the stereoscopic image within a three-dimensional field of view so as to fix a non-paratactic point and to fix a paratactic angle corresponding to the dimension of this region. CONSTITUTION: For example, the stereoscopic image is limited within the three- dimensional field of view to investigate the area for fixing the range of this image within this field of view. The non-parallactic point 52 is fixed within the area for fixing the range of the image and the parallactic angle Ad corresponding to the dimension of this area is fixed so that a both-eye visual model corresponds to this stereoscopic image. As the result of this, by means of the non-parallactic point 52 and the parallactic angle Ad, a stereoscopic image display is capable of displaying the stereoscopic image with an improved three- dimensional characteristic. Thereby images for the right and left eyes by which the observer can blend without feeding a burden on his eyes is generated.
