Classification: CPC H | IPC H

Claim 4:
5. The apparatus of claim 1, wherein:
the photodiode is a first photodiode;
the charge is a first charge;
the digital output is a first digital output;
the voltage is a first voltage;
each pixel cell of the array of pixel cells further comprises a second photodiode configured to generate a second charge in response to incident light;
the charge sensing unit of the pixel cell is configured to, after outputting the first voltage, output a second voltage based on the second charge;
the pixel cell is configured to, after the first digital output is transferred from the in-pixel memory to the frame memory, use the quantizer to quantize the second voltage to generate a second digital output; and
the in-pixel memory is configured to overwrite the first digital output with the second digital output.
