摘要： A black level compensation (BLC) circuit is disclosed. The BLC circuit includes a switched-capacitor (SC) integrator configured to compensate a readout amplifier of an image sensor. An output of the readout amplifier is clamped to a reference voltage at which a black level of the image sensor is defined. According to one aspect, a bad pixel detector is used to detect a bad pixel or pixels and disconnect the BLC loop when the bad pixel or pixels are detected.

摘要： A binning circuit and method for an image sensor is disclosed. A column amplifier (CA) is first reset, and thus generates a CA reset signal. A capacitor and a switch network are coupled between an output of the image sensor and an input of the column amplifier. A correlated double sampling (CDS) circuit controllably receives the output of the column amplifier. The switch network is controlled in a way such that an image signal of a first group of the image sensor is transmitted and stored in the CDS circuit, and an image signal of a second group is then added to the stored image signal of the first group.
