1. A method for controlling dynamic image capturing rate of an optical mouse, the optical mouse having a light source and an image sensor, the light source being lighted at a lighting frequency such that the image sensor can capture external images, the method comprising the steps of:

  • (A) capturing a first image;

    (B) capturing a second image for comparing the first image with the second image and thus finding match parts to determine displacement and moving speed of the optical mouse; and

    (C) proportionally adjusting the lighting frequency of the light source and an image capturing rate based on the moving speed, and then executing step (B).
