ABSTRACT:
Systems and methods are provided for detecting motion within a composite video signal. A first chroma difference element compares an in-phase chroma component of the composite video signal to a delayed representation of the in-phase chroma component to produce a first chroma difference value for a given pixel. A second chroma difference element compares a quadrature chroma component of the composite video signal to a delayed representation of the quadrature chroma component to produce a second chroma difference value for the pixel. A parameter mapping component maps the first and second difference values to respective first and second motion parameters that indicates the degree of change in the chroma properties of the pixel. A parameter selector determines a composite motion parameter for the pixel from the first and second motion parameters.
