An optical pointing device is provided. The optical pointing device includes an image sensor including a photocell array including a plurality of photocells for sensing light and generating an analog signal corresponding to the light, the image sensor sequentially outputting analog signals from the plurality of photocells, a comparator for comparing the signals output from the image sensor to generate a relative comparative signal, and comparing at least one signal output from the image sensor with a comparative signal to generate an absolute comparative signal, and a controller for outputting motion data using the relative comparative signal and outputting a shutter control signal using the absolute comparative signal. The optical pointing device does not include an A/D converter or a pre-filter circuit, thus reducing a chip size of a semiconductor integrated circuit, unlike a conventional optical pointing device. Furthermore, the optical pointing device can obtain high-quality image data and accordingly accurate motion data of an object, by using the comparator having the offset removal and the offset correction circuit external to the image sensor. Also, the use of the second photocell separate from the image sensor can reduce data computational complexity of the shutter control signal controller in the image processor, thus reducing current consumption in the image processor.
