Abstract
A CMOS image sensor with 192/spl times/124 pixels realizes video-rate range sensing with 500 /spl mu/m depth resolution, motion detection, and 12 b digital image output. Each pixel consists of four current copier cells as a frame memory block and a chopper comparator. The imager operates at 48 kframes/s maximum rate and dissipates 1.6 W for range sensing and 2 W for digital imaging at 3.3 V in a 0.35 /spl mu/m process.Keywords
