Black Level Compensation Circuit |
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.
