A Binocular CMOS Range Image Sensor with Bit-Serial Block-Parallel Interface Using Cyclic Pipelined ADC's

Abstract

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 x 16 range image from a pair of 256 x 256 images, together with the dedicated pipelined FFT processor, at 300 frames/s.
