Method and system for automatic detection and suppression of cross-luma and cross-color in a component video signal
A method for automatically detecting and suppressing cross-color and cross-luma present in a baseband component video signal includes receiving component pixel data of a current pixel, a first previous pixel and a second previous pixel. First, second and third differences are calculated based on the component pixel data of the current, first previous and second previous pixels, and the presence of cross-luma and/or cross-color is determined for the current pixel based on an absolute value of at least one of the first, the second and the third differences. A per pixel count associated with the component pixel data of the current pixel is determined based on the determined presence of at least one of cross-luma and cross-color, and the component pixel data of the current pixel is modified based on the per pixel count. The modified component pixel data of the current pixel is outputted as a corrected output color video signal, where the corrected output color video signal is substantially without visual artifacts caused by the at least one of cross-luma and cross-color.
