Abstract: A first stereo camera has a first image pick-up portion and a second image pick-up portion arranged on the right side of the first image pick-up portion in a lateral direction of a vehicular main body. A second stereo camera has a third image pick-up portion and a fourth image pick-up portion arranged on the right side of the third image pick-up portion in the lateral direction of the vehicular main body. The first image pick-up portion and the third image pick-up portion constitute a left image pick-up portion group. The second image pick-up portion and the fourth image pick-up portion constitute a right image pick-up portion group. The left image pick-up portion group and the right image pick-up portion group are arranged at a distance from each other in the lateral direction of the vehicular main body.
