摘要： 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.

摘要： A method of estimating image displacement by block matching for a pointing device used in a computer system. The method provided in the present invention comprises capturing digital images sequentially using a photo capture device, obtaining a template frame and a current frame, estimating a predicted velocity vector, and computing the displacement of the image. The efficiency and reliability of block match searching are improved by reducing the search range according to the calculated displacement. The template block can be defined anywhere on the template frame according to the predicted velocity to extend the lifetime of the template frame, and the displacement vector between the template block and the center of the template frame is proportional to the predicted velocity.
