Abstract:
1. A power-saving sensing module for an optical mouse, the optical mouse having an upper surface and a lower surface, the power-saving sensing module comprising: a light source for providing a light ray; a first sensor for detecting a first image corresponding to a working plane in response to at least a part of the light ray to generate a first sensing signal, wherein the optical mouse operating on the working plane, and the lower surface of the optical mouse facing to the working plane; a first detection unit for generating a displacement signal in response to the first sensing signal; a second sensor for detecting a second image corresponding to an object in response to at least a part of the light ray to generate a second sensing signal; a second detection unit for generating a touch signal corresponding to the object in response to the second sensing signal; and a control unit for outputting a control signal in response to the touch signal of the second detection unit, so that the first detection unit operates at a dormant state or a sensing state in response to the control signal.
