Abstract:
A CT processing unit as an example of a video signal processing apparatus includes: a CT canceling unit which calculates, for each of a first color component and a second color component of each of pixels, a crosstalk component that is produced by a first image and subtracts the crosstalk component from the corresponding one of the signal levels of the pixels of a second image, to generate a modified second image represented as a combination of a signal level of a modified first color component and a signal level of a modified second color component; and a saturation modifying unit which updates the negative signal level of the modified first color component to a value of 0 or larger from among a modified first color component and a modified second color component, and modifies the signal level of the modified second color component according to this update.
