Abstract
A 320/spl times/240 color imaging CMOS sensor with a current-copier cell array and comparators for column-parallel processing accomplishes video rate depth acquisition. The sensor dissipates 82 mW for 3.3kframe/s 3-D sensing with 2.5 mm depth resolution, and 36 mW for 30frames/s imaging with a single CDS circuit for FPN reduction at 3.3 V.
