1. An active pixel image sensor comprising an array of active pixels for producing electrical signals in response to incident radiation and readout circuitry for scanning and processing the pixel outputs into signals corresponding to an image wherein:

  • each active pixel comprises a photodetector and a circuit for amplifying the output of the photodetector;

    the array of pixels comprises a first plurality of pixels whose photodetectors are responsive to a first spectral range and a second plurality of pixels whose photodetectors are responsive to a second spectral range different from the first spectral range;

    the first plurality of pixels and the second plurality of pixels each comprise photodetectors that are monolithically integrated into the same single crystal semiconductor substrate; and

    the pixels of the array are spatially arranged and connected to form a plurality of sub-arrays disposed and arranged to capture essentially the same image.
