Abstract
For reduced processing time involved in an image recognition process, correctorsandcorrects two source images, acquired by two cameras during the imaging of an object, so that when the two source images are arranged side by side in a lateral direction, the imaged object has the same height in both images. A parallax calculation sectioncalculates, by block matching process, a parallax on the basis of the two corrected source images. A parallax image generation sectiongenerates a parallax image on the basis of the parallax calculated by the parallax calculation section. If a block that has been used during block matching has a rectangular shape including an 'm' number of pixels in a longitudinal direction and an 'n' number of pixels in a lateral direction, a first reduced-image generation sectiongenerates a first reduced image from one of the two corrected source images so that the number of pixels in the longitudinal direction is 1/m and so that the number of pixels in the lateral direction is 1/n. Thus, resolution of the first reduced image equals that of the parallax image. An image recognition sectionperforms image recognition of the object, on the basis of the parallax image and the first reduced image.
