Abstract :
Linear current mode CMOS image sensor that performs spatial convolution during pixel readout using low power analog circuitry is presented. The image sensor has 128 by 109 pixel array, digital scanning registers, pixel selection circuitry, and digitally programmable analog processing unit. An intensity image in parallel with two convolved images is provided outside the chip at 60 frames per second. The image sensor was fabricated in 0.5 micron 3M2P process. The sensor operation and performance measurements are presented.
