Abstract
A stereoscopic image display apparatus displays a stereoscopic image using only a single projector. The apparatus includes a photography section for sensing a left image and a right image of an object and converting the left and right images into respective first and second television signals. The first and second television signals are received by a receiving section which then provides the signals to a double-scanning section. The double-scanning section scans the left and right image signals received from the receiving section at a doubled horizontal scan frequency to produce a left double-scanned image signal and a right double-scanned image signal. A multiplexing section then alternately selects the left and right double-scanned image signals at a switching speed of the doubled horizontal frequency to thereby produce a single, multiplexed double-scanned image signal. A projection type display section projects the multiplexed double-scanned image signal onto a single display screen.
