ABSTRACT:
Disclosed herein is a single integrated circuit for an optical mouse. The circuit includes an image pixel array for recognizing light and shadow of a surface under the optical mouse, an analog-to-digital converter for receiving analog signal from the image pixel array and converting analog data into digital data, a motion vector calculation unit for converting the digital data into one-bit data and calculating a motion vector, a motion vector process unit for accumulating motion vectors, correcting errors of the motion vectors, and accumulating moving distances of the optical mouse, a timing signal generator for generating control signals to control an overall operation of the circuit and operation signals pursuant to operation states of the circuit, an interface designed to transmit values processed by the process unit into a personal computer, and a transceiver for enabling one of a universal serial bus or an IBM personal system/2 in the interface.
