1. Area image sensor apparatus comprising:

  • (a) an array of photosites arranged in rows thereof, each of said photosites being responsive to the same wavelength of radiation; and

    (b) means for reading out said photosite array in blocks of photosites wherein a plurality of said blocks are each comprised of a respective plurality of photosite rows that collectively represent two or more effective lines of resolution of a scene imaged upon said array of photosites, and wherein said reading means is effective to cause parallel readout of the photosite rows within each block to produce an output signal comprised of blocks of information in a serial format with each block of information being comprised of a plurality of row signals in a parallel format,thereby reducing the time required for sensor apparatus readout to a fraction of the time required were the sensor apparatus read out one row at a time.
