A camera processor image-processes an image for left eye captured by a left-eye image capturing unit and an image for right eye captured by a right-eye image capturing unit to generate a parallax image of the left-eye image and the right-eye image. A vertical timing adjuster adjusts timings of driving a left-eye image sensor and a right-eye image sensor using a frame synchronizing drive controller to reduce as close to zero as possible an amount of vertical displacement between a framing position of a target object image in the left-eye image and a framing position of a target object image in the right-eye image.
