Global Shutter Pixels
Global shutter CMOS image sensors are used to capture and freeze a scene containing fast moving objects. All pixels are sampled at the same moment in time, producing an image free of distortion. By contrast, rolling shutter image sensors produce motion artefacts when capturing fast moving objects: this distortion is caused by the difference in the time of sampling for pixels at different locations in the sensor.
ams owns IP for fabricating global shutter CMOS pixels that combine true correlated double sampling for low noise with excellent shutter efficiency. The IP is also compatible with backside illumination technology.
