Patent ID: 7327405

Claim:
A method for separating a digitized composite video signal into a luminance component and a chrominance component, comprising: generating a plurality of delayed signals from the digitized composite video signal; selecting one of the delayed signals as a reference signal; selecting a second one of the delayed signals as a first comparison signal; comparing the reference signal with the first comparison signal to obtain first comparison results, wherein the first comparison results include a first degree of motion that characterizes any motion of an object associated with an image corresponding to the reference signal and an image corresponding to the first comparison signal; comparing the comparison results to a threshold, wherein the threshold is adaptive based on at least one measured parameter of the digitized composite video signal; selecting a third one of the delayed signals as a second comparison signal; comparing the reference signal with the second comparison signal to obtain second comparison results, wherein the second comparison results include a second degree of motion that characterizes any motion of the object associated with the image corresponding to the reference signal and an image corresponding to the second comparison signal; comparing the second comparison results to the threshold; and if the first and second comparison results satisfy the threshold, then combing the reference signal to obtain the luminance component and the chrominance component by combining at least a portion of one of the delayed signals with the reference signal, wherein the portion of the one of the delayed signals is determined by the comparison results.
