Abstract:
1. A method of detecting image movement, comprising the following steps: (A) accessing a reference frame, and capturing a reference window from the reference frame; (B) accessing a sampling frame, and searching a sampling window matching the reference window from the sampling frame; (C) when the reference window moves and has not reached a margin of the reference frame, and the sampling window stops moving in the sample frame and has not reached a margin of the sampling frame, capturing a new window from the reference frame to replace the reference window; (D) calculating a moving vector based on relative locations of the reference window and the sampling window; (E) when the sampling window has reached the margin of the sampling frame, replacing the reference frame with the sampling frame, and capturing the reference window from the reference frame; and (F) repeating the step (B).
