The present invention is related to motion detection and motion estimation apparatus and method thereof. In the prior art, motion detection by horizontal/vertical changes is incorrect since only frame difference signals are used. In the present invention, motion detection becomes correct with talking horizontal/vertical changes of image into account. And also, motion detection and motion magnitude are detected and motion estimation can be made. That is, the present invention uses horizontal/vertical difference signals as certain critical values for motion detection judgement, detects left/right motion in the horizontal direction and up/down motion in the vertical direction by performing exclusive OR of horizontal/vertical difference signals frame difference signals, and make horizontal/vertical motion estimation possible by using a ratio of horizontal/vertical signal sums and frame difference signal sums with respect to a K x 3 window. <IMAGE> |
