Claim One:
1. An image processing device comprising: a parallax calculator for calculating a parallax by using a block matching on the basis of two source images of an object that are acquired with two cameras; a parallax image generator for generating a parallax image on the basis of the parallax calculated by the parallax calculator; a first reduced-image generator for generating a first reduced image by reducing at least one of the two source images so that the source image matches with the parallax image; and an image recognizer for performing image recognition of the object, based upon the parallax image and the first reduced image; wherein the first reduced-image generator reduces at least one of the two source images according to a shape of a block used in the block matching, the shape of the block is square or rectangular, and where the number of pixels contained in the block is m in a longitudinal direction and n in a lateral direction, the first reduced-image generator generates the first reduced image by using a predetermined number k greater than or equal to 1 in terms of natural number so that the number of pixels in a longitudinal direction of the first reduced image is the number of pixels obtained by dividing the number of pixels in longitudinal directions of the two source images by (m×k), and so that the number of pixels in a lateral direction of the first reduced image is the number of pixels obtained by dividing the number of pixels in lateral directions of the two source images by (n×k).
