Abstract

See full text

In one example, an apparatus comprises: a photodiode configured to generate charge in response to incident light within an exposure period; and a quantizer configured to perform at least one of a first quantization operation to generate a first digital output or a second quantization to generate a second digital output, and output, based on a range of an intensity of the incident light, one of the first digital output or the second digital output to represent the intensity of the incident light. The first quantization operation comprises quantizing at least a first part of the charge during the exposure period to generate the first digital output. The second quantization operation comprises quantizing at least a second part of the charge after the exposure period to generate the second digital output.
