Recent developments in CMOS image sensors are reviewed. High-speed, wide-dynamic-range, and range or 3D cameras are typical examples of recent success of CMOS image sensors. The fastest CMOS image with 100 M pixels reaches 2000 frames/s. Many techniques for achieving wide dynamic range have been proposed. CMOS image sensors employing wide dynamic range pixels with logarithmic response are applied for imaging of arc-welding process. CMOS sensors for real-time range imaging based on light stripe scanning, TOF (time of flight), and stereoscopic measurement methods are developed. The image quality of CMOS image sensor is being improved by the process technology and signal processing techniques.
