Classification: CPC H | IPC H

Claim 1:
2. The apparatus of claim 1, wherein the one or more photodiodes are configured to, within an integration period, accumulate at least a part of the charge as residual charge until the one or more photodiodes saturates, and to transfer the remaining charge as overflow charge to the one or more charge sensing units after the one or more photodiode saturates;
wherein the one or more charge sensing units comprises a charge storage device having a configurable capacitance;
wherein the plurality of quantization processes comprise:
a first quantization operation to generate a first digital value representing a quantity of the overflow charge received by the charge storage device configured at a maximum capacitance, the first quantization operating being associated with a first intensity range; and
a second quantization operation to, after the residual charge is transferred to the charge storage device configured at a minimum capacitance, generate a second digital value representing a quantity of the residual charge stored at the charge storage device, the second quantization operation being associated with a second intensity range lower than the first intensity range.
