Claim 7:
8. The apparatus of claim 1, wherein:
the photodiode is a first photodiode configured to detect a first frequency component of the light;
the charge sensing unit is a first charge sensing unit;
the charge is a first charge;
the overflow charge is a first overflow charge;
the residual charge is a first residual charge;
the exposure period is a first exposure period;
the digital output is a first digital output to represent the intensity of the first frequency component;
the apparatus further comprises:
a second photodiode configured to generate a second charge in response to a second frequency component of the light within a second exposure period and to accumulate at least a first part of the second charge as a second residual charge; and
a second charge sensing unit configured to accumulate at least a second part of the second charge as a second overflow charge within the second exposure period;

the controller is configured to:
within a third time within the second exposure period, control the quantizer to quantize the second overflow charge accumulated at the second charge sensing unit to generate a third measurement output;
within a fourth time after the third time within the second exposure period, control the quantizer to quantize the second overflow charge accumulated at the second charge sensing unit to generate a fourth measurement output; and
generate a second digital output based on at least one of the third measurement output or the fourth measurement output; and
a first start time of the second exposure period is delayed from a second start time of the second exposure period by a start offset, the start offset being based on a total duration of the first quantization operation and the second quantization operation.
