Abstract
An image sensor and signal processing circuit therefor include a readout circuit, calibration circuitry that calculates a correction coefficient for an effective pixel circuit based on a calibration signal, adjustment circuitry that updates the correction coefficient based on an optical black pixel signal, and correction circuitry that applies the updated correction coefficient to the effective pixel signal and generates an output signal.
