The invention discloses motion detecting method and apparatus thereof. The method and apparatus are utilized to detect a motion condition of a target pixel. The motion detecting method comprises the following steps: receiving a composite signal including a target frame and a reference frame; selecting a first reference pixel from the target frame and selecting a second reference pixel and a third reference pixel from the reference frame; generating a first signal according to the pixel values of the target pixel and the first reference pixel; calculating a first difference between the target pixel and the first reference pixel and a second difference between the second reference pixel and the third reference pixel, and generating a second signal according to the first difference and the second difference; selecting a plurality of first pixels from the target frame and a plurality of second pixels from the reference flame, according to the target pixel, wherein the second pixels correspond to the first pixels; generating a third signal according to the averaged value of the first pixels and the averaged value of the second pixels; and determining a motion condition of the target pixel according to the first signal, the second signal, and the third signal.

Motion detecting method and apparatus thereof

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.
