Abstract
Disclosure is a position tracking sensor of an optical mouse and method of controlling the same. The position tracking sensor comprises an image sensor for receiving light inputted from exterior of the optical mouse to detect an image and outputting image information on the detected image, and a controller for determining whether the optical mouse is spaced apart from a worktable using the image information and turning off a light source when it is determined that the optical mouse is spaced apart from the worktable. Thus, it is possible not only to prevent malfunction of the optical mouse resulting from the image detected by external light when the optical mouse is spaced apart from the worktable, but also to prevent the light source from being unnecessarily turned on and the resulting undesired consumption of electrical power.
