Patent ID: 7742110

Claim:
A system comprising: a Y/C separator operable to separate an image field into luminance and chrominance components; a comb filter operable to temporally process the separated luminance and chrominance components from the image field responsive to image data from at least one other image field, where the comb filter comprises: a cross-chroma detector operable to detect luminance information within the chrominance components from the image field responsive to the image data from the at least one other image field, where the cross-chroma detector is further operable to reduce the chrominance components from the image field responsive to the detected luminance information; a cross-luma detector operable to detect chrominance information within the luminance components from the image field based on the image data from the at least one other image field; and a cross-luma demodulator operable to demodulate the chrominance information and to combine the demodulated chrominance information with the reduced chrominance components; and a non-volatile memory operable to store the image field and the at least one other image field.
