Abstract
A CMOS image sensor with capabilities of real-time 3-D sensing, motion detection and digital image output is developed. It has 192 x 124 pixels, and each pixel consists of 4 current copier cells as frame memories and a chopper comparator for signal processing. The sensor focuses on a temporal response of illumination during exposure. The maximum data rate is 6.25MHz at 48kframes/s operation. The depth resolution of 500um is achieved at 24kframes/s, and 12b maximum image resolution is realized at 48kframes/s. This sensor is fabricated with 0.35μm standard CMOS technology.
