ABSTRACT:
A method to detect the movement of an image sensor. Movement is detected according to a first, second, third, and fourth frame, all captured by the image sensor. A first captured image region is captured from the first frame. Then, a first corresponding region matching the first captured image region is captured from the second frame, wherein the first corresponding region shifts in a predetermined direction relative to the first captured image region. Next, a second captured image region is captured from the third frame, wherein the second captured image region shifts in a direction opposite to the predetermined direction relative to the first captured image region. Then, a second corresponding region matching the second captured image region is captured from the fourth frame. Finally, the movement of the image sensor is determined according to the second captured image region and the second corresponding region.
