A three-dimensional image pickup apparatus for capturing right and left images with a first imaging unit and a second imaging unit to generate a stereoscopic image is provided. In this three-dimensional image pickup apparatus, each of the first imaging unit and the second imaging unit includes a lens group including a zooming lens and a focusing lens, and a imaging device for converting an optical image from the lens group into an electrical signal, and the three-dimensional image pickup apparatus includes a driving controller operable to drive the zooming lens and the focusing lens of the first imaging unit and the second imaging unit, along a tracking curve showing a relationship of a position of the zooming lens and a position of the focusing lens, and the driving controller limits a range of moving the zooming lens and the focusing lens in either one of a first range and a second range, the first range ranges from a wide-angle end in the tracking curve to a inflection point at which the moving direction of the focusing lens is inverted, and the second range ranges from a telephoto end to the inflection point.
