Abstract:
In a system for simultaneously displaying a plurality of stereoscopic images in a windowing environment, a stereoscopic TV apparatus comprising:a resolution discrimination section for discriminating the kind of an input image signal by detecting a synchronization frequency of said input image signal; a window information management section for detecting the size of each individual window where a stereoscopic image is displayed; a viewing distance measuring section for measuring a viewing distance of a viewer; 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; an optimum parallax determining section for calculating the actual size of each individual window from the output of said resolution discrimination section, the output of said window information management section, and the size of a display screen, calculating the magnitude of binocular parallax of an image calculated from the size of said window, the output of said parallax calculation section, and the output of said viewing distance measuring section, and for computing an amount of parallax change necessary to bring said binocular parallax within a binocular fusional range of said viewer; and a 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 the stereoscopic image displayed in each individual window will be brought within the binocular fusional range of said viewer even if the size of each individual window or the synchronization frequency of the input image frequency changes due to an operation by said viewer.
