Abstract
In one example, an apparatus comprises: multiple distinct sets of photodiodes, wherein each set of photodiodes includes one or more photodiodes, one or more charge sensing units, and a controller. The controller is configured to: transfer charge generated by the one or more photodiodes in response to a different component of incident light to the one or more charge sensing units in order to convert the charge to voltages; perform one or more quantization processes of a plurality of quantization processes corresponding to a plurality of intensity ranges, wherein the one or more quantization processes quantizes 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 at least some of the digital values.
