    Abstract: The present invention discloses a hybrid pointing device including an optical navigation module and a pointing module. The optical navigation module is configured to replace the conventional buttons of a convention pointing device, such as an optical mouse or a trackball mouse. The optical navigation module is configured to sense gestures of at least one object operated by a user to activate commands associated with particular programs running on the host. Since the optical navigation module is only configured to sense gestures of the object but not the movement of the hybrid pointing device relative to a surface, the resolution thereof is aimed to be sufficiently high enough for sensing gestures and no need to be relatively high.

    Abstract: A light source transmits detecting light toward an object. The object reflects the detecting light and forms a reflected light. A sensor is used for sensing the reflected light. Then, an exposure control unit coupled to the sensor performs luminance convergence on the reflected light according to luminance of the reflected light sensed by the sensor. And a distance measurement device coupled to the sensor detects a distance between the object and the light source and/or the sensor according to an image position of the reflected light on the sensor.

    Abstract: An optical sensor, comprising: a sensor array, comprising a bright region with at least one bright pixel and comprising a dark region with at least one dark pixel, wherein the dark pixel generates a sensing signal that is non-relevant to light emitted to the sensor array; a power noise detection circuit, configured to compute a power noise level of the sensing signal from the dark pixel; and a power noise compensation circuit, configured to control the optical sensor to perform a power noise compensation operation according to the power noise level. A related power noise reduction method is also disclosed. Based on the present invention, the power noise of the optical sensor can be reduced without increasing the power consumption, and the power noise for a low switch frequency can also be improved.
