Patent ID: 8582868

Claim:
An image signal processing device that cancels crosstalk in three-dimensional (3D) image signals, said image signal processing device comprising: an image adaptation control unit configured to (i) receive a first image signal and a second image signal, the first image signal being one of a left-eye image signal and a right-eye image signal which correspond to each other in the inputted 3D image signals, and the second image signal being an other one of the left-eye image signal and the right-eye image signal, and (ii) determine a first coefficient and a second coefficient such that the larger a signal level of the second image signal relative to a signal level of the first image signal, the larger the first coefficient and the second coefficient become in at least a predetermined range, when the signal level of the first image signal is compared to the signal level of the second image signal; a first conversion unit configured to convert the second image signal based on the first coefficient determined by said image adaptation control unit; a second conversion unit configured to convert the first image signal based on the second coefficient determined by said image adaptation control unit; and a corrected signal generation unit configured to correct the first image signal by subtracting the second image signal converted by said first conversion unit from the first image signal converted by second conversion unit.
