Abstract: The present invention discloses an electronic system and a pointing device thereof. The pointing device includes an image sensor and a processor. The image sensor sequentially generates a first image frame and a second image frame, wherein the first image frame has two images related to a sensed target, and the second image frame has one image related to the sensed target. The processor determines one image position representing the sensed target using the first image frame, and subsequently determines one image displacement using the first image frame and the second image frame.

Abstract: An electronic system includes an image-sensing device and a processor coupled with the image-sensing device, The image-sensing device includes an image-sensing area configured to generate a picture. The picture includes a noisy region. The processor is configured to select a tracking region from the portion of the picture outside of the noisy region. The tracking region corresponds to an operative region of the image sensing area.
