Abstract
In one example, an apparatus comprises: a plurality of photodiodes, one or more charge sensing units, one or more analog-to-digital converters (ADCs), and a controller. The controller is configured to: enable the each photodiode to generate charge in response to a different component of the incident light; transfer the charge from the plurality of photodiodes to the one or more charge sensing units to convert to voltages; receive a selection of one or more quantization processes of a plurality of quantization processes corresponding to a plurality of intensity ranges; based on the selection, control the one or more ADCs to perform the selected one or more quantization processes to quantize the voltages from the one or more charge sensing units to digital values representing components of a pixel of different wavelength ranges; and generate a pixel value based on the digital values.
