Embodiment Construction
[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
[0024] exist figure 1 Among them, reference numeral 1 as a whole denotes a stereoscopic viewing device. A video signal for a left eye (hereinafter referred to as a left eye video signal) S2L and a video signal for a right eye (hereinafter referred to as a right eye video signal) S2R with parallax are generated from a single input television signal S1. An image based on each of the left-eye video signal S2L and the right-eye video signal S2R is displayed on the display device 2 .
[0025] In this case, the stereoscopic viewing apparatus 1 converts the received input television signal S1 into television data D1 at a sampling frequency of 13.5 MHz through an analog-to-digital conversion circuit (A / D) 3 . This television data D1 is directly supplied to the blocking circuit 4 for sorting, and is also supplied to the blocking circuit 4 for sorting throug...

A stereoscopic viewing device and a stereoscopic viewing method, and makes it possible to provide a satisfactory stereoscopic image without increasing of the quantity of recorded information and the quantity of transmitted information. According to the invention, the input television signal is classified respectively on the basis of the level distribution pattern for every pixel in the spatio-temporal region whose center is lying on each attentional pixel, and the input television signal is blocked separately so as to generate the pixel data for predictive calculation, and the predictive calculation of the predictive calculating pixel data is processed utilizing the predictive coefficient which is corresponding to the result of classification obtained from the classifying means out of the predictive coefficients of each set which have been previously prepared, so as to generate the video signal for left eye and the image signal for right eye respectively, and then the stereoscopic image is displayed on the basis of the video signal for left eye and the video signal for right eye; in this way a stereoscopic image can be projected on the displaying means such that a flicker is eliminated and a deterioration of the image quality is prevented.
Description
technical field [0001] The present invention relates to a stereoscopic viewing device and a stereoscopic viewing method, and more particularly relates to a stereoscopic viewing device using an input video signal to display a stereoscopic image. Background technique [0002] Previously, various stereoscopic viewing devices have been proposed, such as those disclosed in "The Report of The Television Institute Vol. 45, No. 4, PP. 446-452 (1991)". [0003] In these stereoscopic viewing devices, in which two images corresponding to the left eye and the right eye have parallax, they are displayed on a television monitor in such a manner that they are alternately switched every field, and the displayed images are viewed through liquid crystal shutter glasses , in which the left-eye shutter and right-eye shutter are opened and closed synchronously with the displayed image, thus achieving stereoscopic viewing. [0004] Thus, in the method of achieving stereoscopic viewing by alterna...
