PROBLEM TO BE SOLVED: To provide an adjustment device for a stereo camera capable of shortening the time required for detection processing of a positional deviation of the camera. SOLUTION: A calculation part 21b uses an image acquired by imaging an image 50 for adjustment by a camera 12 as a reference image, and moves an object image acquired by imaging the image 50 for adjustment by a camera 13, relative to the reference image, while calculating the area of each outer shape of two overlapped patterns 51a, 52a for adjustment at each position of the reference image. A position detection part 21b detects the minimum position, where the area value becomes a minimum by comparing each area value at each position. A control part 21 moves the camera 13 to the minimum position, by controlling a driving device 23, and adjustment for positional deviation is carried out. COPYRIGHT: (C)2008,JPO&INPIT
