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: There is provided a structure to improve BSI global shutter efficiency. In a sensor pixel circuit, at least one strong electric field is formed at the position of a floating diffusion region to accordingly have the effect of shielding the floating diffusion region. Or, the semiconductor material from the floating diffusion node toward a light incident direction is removed in the manufacturing process such that a depletion region cannot be formed in this direction. Or, a reflection layer or a photoresist layer is formed in the light incident direction to block the light. In these ways, charges generated by the undesired noises are reduced, and noise charges are difficult to reach the floating diffusion region thereby improving the shutter efficiency.

Abstract: The present disclosure is related to an optical encoder which is configured to provide precise coding reference data by feature recognition technology. To apply the present disclosure, it is not necessary to provide particular dense patterns on a working surface. The precise coding reference data can be generated by detecting surface features of the working surface.
