摘要： An optical navigation sensor device and an image processing method using a 2-dimensional sequential image process are disclosed. A pre-processor stores digital voltage values of respective pixels of an image received from a pre-processor in a memory, performs a pre-process for the digital voltage values of respective pixels sequentially received from the memory, thereby producing a pre-processed current image, and extracts a pre-processed current central image from the pre-processed current image. A motion coordinate calculator stores the pre-processed current central image as X/Y-axis reference image candidates, determines replacement of X/Y-axis reference images for calculation of motion coordinate values of a next pre-processed image in accordance with X/Y-axis motions of the pre-processed current image, and compares the pre-processed current image with the X/Y-axis reference images, thereby calculating X/Y-axis motion coordinate values of the pre-processed current image.

摘要： Disclosed herein is a method for processing image data of an optical mouse. In the method for processing image data of an optical mouse, direction and size values of motion vectors which are image data consecutively inputted from an image pixel array are filtered with respect to X and Y axes by a filter. A predetermined number of motion vectors converted by and outputted from the filter are accumulated, and the accumulated values are mapped to conversion values to attenuate noise components and amplify directionality of the motion vectors depending on a speed of the optical mouse by a mapper. The values mapped by the mapper in a plurality of pipes are stored, and a value obtained by adding the plural stored values to each other and dividing the added result value by a conversion factor is transmitted to a personal computer (PC) interface such as a Universal Serial Bus (USB) or PS/2. Accordingly, the present invention is advantageous in that it minimizes noise components of the optical mouse, and consequently ensures the unnatural movement of a cursor on a PC screen.
