Patent ID: 7443454

Claim:
A method for treating inter-frame motion in a series of consecutive signal frames of a composite video signal; the method comprising the steps of, for an evaluation pixel position in each frame of a test frame-set, said test frame-set including three successive signal frames of said series of consecutive signal frames: (a) determining whether there is at least a predetermined difference in chroma component signals or a predetermined difference in luma component signals at said evaluation pixel in said test frame-set; (b) if in step (a) there is not a predetermined difference in chroma component signals or a predetermined difference in luma component signals at said evaluation pixel in said test frame-set, determining whether a first signal frame of said test frame-set is substantially identical with a third signal frame of said test frame-set; (c) determining whether at least a first predetermined number of said luma component signals in said test frame-set present at least one false color; and (d) determining whether at least a second predetermined number of high frequency luma component signals exist in said test frame-set.
