In this particular CMOS image sensor chip, two image arrays and 32-channel parallel pipeline analog-to-digital converters are integrated. The parallax between two images is estimated by a phase-only correlation (POC). The developed 3-D imaging system can be used for PCB board inspection. As shown below, the CMOS image sensor developed can detect a tiny electronic components whose height is 0.5mm at 300 frames/s.
