Image Sensor Circuit |
摘要 |
An image sensor circuit includes a CMOS image sensor with light sensitive pixels arranged in rows and columns and a readout circuitry. The readout circuitry includes storage means with a CDS stage for storing signals read out from the pixels at two different time instants between two subsequent reset phases and an analogue-to-digital converter, wherein the CDS stage comprises a subtracting means for subtracting the stored signals from each other and wherein the result of the subtraction is fed to the analogue-to-digital converter as a differential signal.
