US 7,443,454 B2 · Method for treating inter-frame motion in a composite video signal

Abstract

A method for treating inter-frame motion in a series of consecutive signal frames of a composite video signal includes the steps of, for an evaluation pixel position in each frame of a test frame-set including three successive signal frames: (a) determining whether there is at least a predetermined difference in chroma component or in luma component signals at the evaluation pixel; (b) if in step (a) there is not a predetermined difference in chroma component signals or in luma component signals, determining whether a first and third frame of the test frame-set are substantially identical; (c) determining whether at least a first predetermined number of the luma or chroma component signals in the 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 the test frame-set.

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.
