ELECTRONIC SYSTEM WITH POINTING DEVICE AND METHOD THEREOF
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.
