摘要： 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.

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.

摘要： A method of processing data of a defect sector in a DVD-RAM (Digital Video Disk-Random Access Memory) system and the DVD-RAM system. In the method, a defect list is read from a lead-in area of a DVD-RAM disk during playback of the disk and stored in a predetermined area of a memory of a signal processing portion in the system. A sector having the title of a user-input file is searched, a physical sector address for the searched sector is designated, the defect list is read, and it is determined whether the physical sector address is in the defect list. Then, sector data corresponding to the physical sector address is stored in the memory of the signal processing portion if the physical sector address is not in the defect list, and otherwise, no sector data corresponding to the physical sector address is stored in the memory.
