SYSTEM AND A METHOD FOR PERFORMING OPTICAL NAVIGATION USING ENHANCED FRAMES OF IMAGE DATA, PARTICULARLY FOR REMARKABLY IMPROVING TRACKING PERFORMANCE OF AN OPTICAL NAVIGATION SYSTEM

摘要

PURPOSE: A system and a method for performing optical navigation using enhanced frames of image data are provided to properly perform a tracking operation for the relative movement of an optical mouse for a target surface by removing a space noise pattern in a frame of image data on a target surface.;CONSTITUTION: A spatial noise pattern estimation module(220) generates a spatial noise pattern estimation value of a spatial noise pattern in a frame through at least some of a frame of image data, and the spatial noise pattern is generated resulting from the contamination of components of an optical navigation system(100). A normalization module(222) normalize the frame of the certain image data based on the spatial noise pattern estimation value, and a navigation engine(226) generates a displacement value.;COPYRIGHT KIPO 2010
