In one embodiment, an element 106 transform, with a voltage, non-polarized light into plane polarized light with an arbitrary plane of polarization. A synchronizer 112 gives the plane of polarization control element 106 an instruction to rotate the plane of polarization, thereby getting the plane of polarization of the illumination rotated and casting that polarized light toward the object. At the same time, the synchronizer 112 sends a shooting start signal to an image sensor 110, thereby getting video. The synchronizer 112 performs these processing steps multiple times. A captured video signal is sent to an image processing processor 108, where LL, RR and CC images are separately generated as images of light rays that have passed through left and right polarizing areas and the central non-polarizing area and left and right parallax signals are generated and sent to a 3D display section 122.
