A binocular CMOS range image sensor with bit-serial block-parallel interface using cyclic pipelined ADC's

摘要

A binocular CMOS image sensor used with a pair of aligned-in-parallel optical systems for range imaging is presented. Therty-two compact cyclic pipelined analog-to-digital converters are integrated. The image sensor produces a 16 × 16 range image from a pair of 256 × 256 images, together with the dedicated pipelined FFT processor, at 300 frames/s.
