A prototype of 34x34 pixels vision sensor with on focal plane image processing is presented. The sensor perform a wide range of image filtering over a 3x3 pixel kernel, based on two operations: Absolute Value of the Difference (AVD) between two signals and Signal Accumulation (SA). These two functions are implemented at pixel-level thanks to a high pixel connectivity, allowing both pixel parallel comp utation with large flexibility in coefficients assignment. The pixel occupies 35x35 um2 of chip area with a fill factor of 20%. The total dynamic range of the sensor is 98 dB. The array was fabricated in 0.35 um CMOS technology and consumes 6 mW @ 3.3 V.
