Patent ID: 8681148

Claim:
A method for correcting stereoscopic images in which a stereoscopic image displayed based on a left image and a right image is corrected, the method comprising: (a) inputting said left image and said right image and detecting a range of crosstalk and a crosstalk amount occurring on said left image or on said right image of black-side correction data for crosstalk causing bright display based on crosstalk characteristic data obtained based on gradation of said left image and gradation of said right image, and detecting the range of crosstalk and the crosstalk amount of white-side correction data for crosstalk causing dark display based on crosstalk characteristic data obtained based on gradation of said left image and gradation of said right image; (b) inputting said black-side correction data into a black-side smoothing filter after said step (a), the black-side smoothing filter allowing said black-side correction data to have a smooth slope from an inside of the range where said crosstalk occurs to an outside of the range where said crosstalk occurs and making said black-side correction data into lower-limit data, and inputting said white-side correction data into a white-side smoothing filter after said step (a), the white-side smoothing filter allowing said white-side correction data to have a smooth slope from an inside of the range where said crosstalk occurs to an outside of the range where said crosstalk occurs, and making said white-side correction data into upper-limit data; and (c) gamma-converting said left image or said right image based on at least one of said lower-limit data and said upper-limit data after said step (b), and generating a corrected left image or a corrected right image.
