Abstract
The present invention uses a single television camera (40), an optical system, and a plurality of optical paths comprising a plurality of mirrors (22), (23), and (26), and shutters (24) and (27) for blocking light. Object images from the optical paths are alternately selected in synchronization with the field scanning operation of the television camera (40) to be projected into the television camera (40) so that a final image is picked up in three dimensions. The imaging device (FIG. 2) used in the television camera (40) has two-dimensionally arranged photoelectric converting elements (42) and corresponding vertical transfer stages (43), and is designed so that signal charges accumulated in the two-dimensionally arranged photoelectric converting elements (42) are transferred simultaneously to the corresponding vertical transfer stages (43). The timing of selecting the object images for projection into the television camera (40) is approximately in synchronization with the timing of transferring the signal charges from the photoelectric converting elements (42) to the corresponding vertical transfer stages (43).
