1. A digital camera comprising: a plurality of arrays of photo detectors, including: a first array of photo detectors to sample an intensity of light; and a second array of photo detectors to sample an intensity of light; a first channel processor coupled to the first array and configured to generate a first image using first array data which is representative of the intensity of light sampled by the first array; a second channel processor coupled to the second array and configured to generate a second image using second array data which is representative of the intensity of light sampled by the second array; and a semiconductor substrate, wherein the first array, the second array, the first channel processor and the second channel processor are integrated on or in the substrate.
