STEREOSCOPIC TELEVISION DEVICE

摘要

PROBLEM TO BE SOLVED: To automatically adjust parallax quantity between both eyes in accordance with the size of a screen and to attain more natural stereoscopic viewing to be easily observed by controlling right and left pictures so that a displayed stereoscopic picture is included within an observer's inter-eye merging area. SOLUTION: The resolution of an input picture is discriminated by detecting the horizontal-vertical frequency of an input picture signal by a resolution discriminating part 9. A parallax calculating part 8 calculates depth information (a parallax map) on each point of the input picture, based upon right and left picture signals and outputs the largest value (the inter-eye parallax of the farthest subject). Then a suitable parallax determining part 10 determines the parallel moving distances of the right and left pictures for enabling an observer of a stereoscopic TV to execute the inter-eye merging of the displayed stereoscopic picture.
