An image compensation circuit for an image sensor includes a gain amplifier, a compensation control circuit, a memory and a digital-to-analog converter (DAC). The gain amplifier is used for receiving a plurality of image signals from the image sensor and amplifying the plurality of image signals. The compensation control circuit is used for generating a plurality of compensation values for the plurality of image signals. The memory, coupled to the compensation control circuit, is used for storing the plurality of compensation values. The DAC, coupled to the memory and the gain amplifier, is used for converting the plurality of compensation values into a plurality of compensation voltages, respectively, to compensate the plurality of image signals with the plurality of compensation voltages.

Image compensation circuit and method

In some embodiments, an input device includes a housing having a top surface, a touch sensor disposed on the top surface of the housing, and a processor disposed in the housing. The touch sensor can be configured to detect a contact by a hand on the top surface of the housing and generate touch data corresponding to the detected contact by the hand. The processor can be configured to control operation of the touch sensor and receive the touch data, determine an orientation of the hand with respect to the housing based on the touch data, and calibrate a detected movement of the input device based on the determined orientation of the hand with respect to the housing. An image sensor and/or one or more IMUs can be used to detect 2D and/or 3D movement of the input device.

Input device

A finger stability detecting method for a fingerprint sensing device includes triggering a pressure sensing function, receiving a pressure sensing value which is generated in response to triggering the pressure sensing function, and determining whether a finger touch is stable according to at least the pressure sensing value.
