Abstract :
A binary image sensor with motion vector detection has been developed and successfully tested. The sensor acquires binary images and detects motion vectors using block matching method. The size of matching blocks and the search area of motion vectors are variable. The block matching is realized by a 2-D shift-register, XOR circuits and block current-sum circuits. The sensor integrates 32/spl times/32 pixels on a 7.3 mm/spl times/7.3 mm die in a 1.2 /spl mu/m CMOS 2-Metal 2-poly-Si process.
