Disclosed is an optical pointing system, a signal transmission method of the same, and a signal processing method of a computer used in the optical pointing system. The optical pointing system comprises an image sensor for outputting an analog signal corresponding to a surface image, a signal conversion section for converting the analog signal of the image sensor into a digital image signal, a movement value calculation circuit for calculating a movement value using the digital image signal of the signal conversion section and outputting the calculated movement value, and a computer interface for receiving the digital image signal and the movement value and transmitting the digital image signal and the movement value to a computer. Thereby, an image signal of a worktable surface on which the optical pointing system is placed can be processed at not only the optical pointing system but also the computer, so that it is possible to calculate the accurate movement value of the optical pointing system. Further, the optical pointing system can provide the high accurate image signal to the computer, so that it is possible to function as a scanner.
