Abstract
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.
