• abstract: The development of the CMOS active pixel sensor (APS) has, for the first time, permitted large scale integration of supporting circuitry and smart camera-functions on the same chip as a high-performance image sensor. This paper reports on the demonstration of a new 128/spl times/128 CMOS APS with programmable multiresolution readout capability. By placing signal processing circuitry on the imaging focal plane, the image sensor can output data at varying resolutions which can decrease the computational load of downstream image processing. For instance, software intensive image pyramid reconstruction can be eliminated. The circuit uses a passive switched capacitor network to average arbitrarily large neighborhoods of pixels which can then be read out at any user-defined resolution by configuring a set of digital shift registers. The full resolution frame rate is 30 Hz with higher rates for all other image resolutions. The sensor achieved 80 dB of dynamic range while dissipating only 5 mW of power. Circuit error was less than -34 dB and introduced no objectionable fixed pattern noise or other artifacts into the image.
