ABSTRACT:
Disclosed herein is a method of processing data of an optical mouse. The method includes the steps of calculating a motion vector of the optical mouse through processing of digitally converted image pixel data in an Image Signal Processor (ISP) by sequentially overlapping a reference image of an n−1 th frame to a present image of an nth frame and determining a moving direction of the optical mouse using approximately equal parts in the reference and present images; and transmitting the calculated motion vector to a personal computer through an interface; wherein the ISP includes an X axis navigation engine for processing data on a reference image for the motion of an X axis direction among the processed image pixel data and a Y axis navigation engine for processing data on a reference image for the motion of a Y axis direction among the processed image pixel data.
