STEREO CAMERA AND STEREO CAMERA SYSTEM

The present invention provides a technique that is capable of improving the precision of a distance measurement made using a stereo camera, and is capable of reducing the size of a stereo camera device. The stereo camera is equipped with left and right imaging systems (1a, 1b) having left and right optical systems (2a, 2b) and left and right imaging elements (3a, 3b), and derives the distance to an imaging target on the basis of an image signal acquired by imaging the imaging target by means of the left and right imaging systems (1a, 1b). The light receiving surface of the left and right imaging elements (3a, 3b) in the left and right imaging systems (1a, 1b) is caused to bend in the direction of the optical axis so as to correct an aberration in the left and right optical systems (2a, 2b).
