    Abstract: A method for detecting spot position is provided. The method includes the following steps. Firstly, a number of primary light sensing pixels are enabled, wherein each primary light sensing pixel includes a number of secondary light sensing pixels. Then, a region of the primary light sensing pixels in which a light the spot is located is determined according to a first sensing value received by each primary light sensing pixel. Then, the secondary light sensing pixels outside the region are disabled. Then, a position of the spot is obtained according to a second sensing value received by the secondary light sensing pixels that are not disabled.
