GRID SIGNAL RECEIVER WITH INCREASED POINTING PERFORMANCE CAPABLE OF INCREASING MOTION VECTOR SENSITIVITY AND RESOLUTION, A WIRELESS POINTING SYSTEM WITH THE SAME, AND A GRADIENT CORRECTING METHOD IN THE WIRELESS POINTING SYSTEM

摘要

PURPOSE: A grid signal receiver with increased pointing performance, a wireless pointing system with the same, and a gradient correcting method in the wireless pointing system are provided to enable four sensors to recognize signals wherein the four sensors cross each other.;CONSTITUTION: A grid signal receiver(20) comprises first and second X detectors and first and second Y detectors. The first and second X detectors detect a vertical pattern signal of a grid. At least two sensors are horizontally arranged in the first and second X detectors. The first and second Y detectors detect a horizontal pattern signal of a grid. The first and second Y detectors are vertically arranged in at least two sensors.;COPYRIGHT KIPO 2012
