Abstract
A motion detection method for detecting the difference in colors and an object position between a current frame and a previous frame through processing a composite video signal corresponding to both frames. The method includes: calculating a plurality of composite signal values included in the composite video signal to generate a calculation result; determining whether the calculation result conforms to a requirement to obtain a detecting result; and determining whether the colors and the object position are changed in two frames corresponding to the composite video signal according to the detecting result.
