STEREOSCOPIC IMAGE DISPLAY SYSTEM, DISPARITY CONVERSION DEVICE, DISPARITY CONVERSION METHOD, AND PROGRAM

摘要

To reduce burden of a viewer at the time of performing stereoscopic display by a stereoscopic display device and to show a stereoscopic image in a natural and comfortable manner.;A disparity estimating unit 210 estimates disparity from the left and right images of an input image to generate a disparity map. A disparity analyzing unit 230 analyzes the disparity map to generate a disparity control parameter for performing suitable disparity control. A disparity control unit 240 controls the content of processing at an image conversion unit 250 in accordance with the disparity control parameter. The image conversion unit 250 performs image conversion on the input image based on the control by the disparity control unit 240 to output an output image. The image conversion unit 250 performs image conversion of two steps. The image conversion unit 250 performs shift processing for shifting the relative positions of the left and right images of the input image in the horizontal direction as first step image conversion, for example. The image conversion unit 250 performs scaling processing for performing enlargement/reduction of the entire screen with each center of the left and right images as a reference, as second step image conversion, for example.

1. A disparity conversion device comprising:
a first image conversion unit configured to subject each of the left image and right image of an input image to first step image conversion; a second image conversion unit configured to subject each of the left image and right image subjected to said first step image conversion to second step image conversion to generate an output image; a disparity estimating unit configured to estimate disparity from the left image and right image of said input image to generate a disparity map that holds disparity for each pixel or each pixel group; a disparity analyzing unit configured to analyze said disparity map to generate a disparity control parameter so that the distribution of said disparity in said input image is included in a predetermined range; and a disparity control unit configured to control image conversion at said first and second image conversion units based on said disparity control parameter.
