Provided are an optical pointing device and a data transmission method thereof. The optical pointing apparatus includes: an optical pointing sensing part for receiving an image of a subject to output digital image data and a motion value; an input signal analysis part for receiving a command from the host computer and analyzing the type of the command to output first and second operation control signals; a data input/output controller for outputting the motion value in response to the first operation control signal and outputting the digital image data in response to the second operation control signal; and a computer interface for receiving the motion value and the digital image data having different data transmission protocols to directly transmit the value and the data to the host computer. Therefore, it is possible to accurately analyze an optical state in the optical pointing device and detect defects in an image sensor and peripheral parts, and transmit image data to a host computer having different data protocol, without separating an optical pointing device chip from a printed circuit board in the optical pointing device and risking damage to the printed circuit board.
