Abstract:
A stereoscopic TV apparatus comprising:a parallax calculation section for calculating binocular parallax from left-eye and right-eye images, and for calculating a maximum or minimum value of said binocular parallax;a viewing distance measuring section for measuring a viewing distance of a viewer;a resolution discrimination section for discriminating the kind of an input image signal by detecting a synchronization frequency of said input image signal;an optimum parallax determining section for calculating the magnitude of binocular parallax of a displayed image from the output of said parallax calculation section, the output of said viewing distance measuring section, the output of said resolution discrimination section, and the size of a display screen, and for computing an amount of parallax change necessary to bring said binocular parallax within a binocular fusional range of said viewer; anda parallax control section for, in accordance with the output of said optimum parallax determining section, translating the left-eye and right-eye images in horizontal directions so that stereoscopic images will be displayed within the binocular fusional range of said viewer even if the synchronization frequency of the input image frequency changes.
