1. An image pickup device comprising:
- plural image pickup systems;
a search unit adapted to search paired corresponding points between plural images obtained from said plural image pickup systems in a search area set in the plural images; and
a search range control unit adapted to detect an overlapping area between the plural images according to phototaking parameters of the plural images and to determine the range of the search area set in the overlapping area of the plural images to be searched by said search unit.

Abstract
For facilitating the search of corresponding points in plural images obtained from plural image pickup systems, in obtaining left and right images from left and right image pickup systems and searching two corresponding points in the two images by a corresponding point extraction unit, the search range thereof is determined according to the phototaking parameters of the image pickup systems. The paired corresponding points, thus extracted, are synthesized, in a synthesis/conversion unit, into a panoramic image or a high definition image. Thus achieved are a reduction in the search time and an improvement in the precision of search.
