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.

Claim (Index 4):
The signal processing circuit according to  claim 3 , further comprising a first switch and a second switch, wherein\n the first switch is configured to connect the digital to analog converter to an input of the readout circuit and to connect the calculation circuitry to an output of the readout circuit during a first time period in which the calculation circuitry calculates the correction coefficient, and the second switch is configured to connect the pixel circuit to the input of the readout circuit and to connect the adjustment circuitry to the output of the readout circuit during a second time period in which the adjustment circuitry updates the correction coefficient.
