Abstract
In one example, an apparatus comprises: a photodiode configured to generate a charge in response to light within an exposure period, a charge sensing unit configured to accumulate at least a part of the charge as an overflow charge, a quantizer, and a controller configured to: within a first time within the exposure period, control the quantizer to perform a first quantization operation to quantize the overflow charge accumulated at the charge sensing unit to generate a first measurement output; within a second time after the first time, and within the exposure period, control the quantizer to perform a second quantization operation to quantize the overflow charge accumulated at the charge sensing unit to generate a second measurement output; and generate a digital output to represent an intensity of the light based on at least one of the first measurement output or the second measurement output.
