1. An optical pointing device, comprising:
a light emitting unit, for emitting light to a surface; a pixel array, for sensing the light reflected from a surface to generate at least one sense resultant signal; a gain controlling circuit, coupled to the pixel array, for controlling a gain value for the at least one sense resultant signal, to avoid signal saturation; and a processing circuit, coupled to the gain controlling circuit, for performing image capturing for a navigation of the optical pointing device; wherein the gain controlling circuit and the processing circuit concurrently control the gain value and perform the image capturing for the navigation of the optical pointing device. |
