Abstract :
A CMOS PWM imager which realizes block summation and 2D projection of a thresholded image, in addition to row-parallel PWM readout with gray scale, is reported. An imager including 56/spl times/56 pixels, an address signal generator, and a signal processing circuit is fabricated in a 6 mm/spl times/6 mm chip with a 0.8 /spl mu/m CMOS technology.
