Abstract:
1. A stereo image processing apparatus comprising: a first camera; a second camera; a third camera placed between the first camera and the second camera; a first parallax detecting unit for performing matching between a first image picked up by the first camera and a second image picked up by the second camera to determine correspondence regions in which a difference between image signals is at a minimum for each predetermined unit region and for detecting a deviation between a position in the first image and a position in the second image in the correspondence regions as a first parallax; a second parallax detecting unit for performing matching between a first image picked up by the first camera and a third image picked up by the third camera to determine correspondence regions in which the difference between image signals is at a minimum for each predetermined unit region and for detecting a deviation between a position in the first image and a position in the third image in the correspondence regions as a second parallax; a parallax combining unit for combining the first parallax and the second parallax; and a distance calculating unit for calculating, for each predetermined unit region, a distance to a subject corresponding to the unit region based on the combined parallax.
