MULTI-EYE IMAGE PICKUP DEVICE, ADJUSTING METHOD AND DEVICE THEREFOR, AND IMAGE-AREA ADJUSTING SYSTEM AND METHOD

A multi-eye image pickup device includes a left-side optical unit and a right-side optical unit. At a time of adjustment, an adjustment target mark is located so as to be slightly shifted in a faraway direction relative to a subject position where a subject is shot. The adjustment target mark is taken by the respective optical units, and images taken thereby are analyzed to find a clip area of each optical unit. The clip area has a predetermined size and the center thereof is positioned at the image of the adjustment target mark. The respective clip areas are stored in a correction memory of the multi-eye image pickup device. At a time of subject shooting, an image of the stored clip area is clipped from a shooting image taken by each optical unit.
