Abstract :
This vision sensor outputs luminance, contrast magnitude and contrast orientation of image features for surveillance and automotive applications. The sensor produces a contrast representation with a dynamic range of 120 dB and a sensitivity of 2%. The chip is fabricated in a 0.5 /spl mu/m 3M 2P process and dissipates 300 mW at 3.3 V.
