sony pregius & pregius S
Pregius is a global shutter pixel technology based on Sony's low noise CCD structure. Active pixel CMOS image sensors used in these products produce high quality images.
This technology was named Pregius to represent the combination of the low noise performance of CCD with the high speed and high precision performance (Precision GS) of global shutter (GS) required by FA applications.
In industrial applications there is often a demand to recognize the accurate form of fast moving objects. Until now, a rolling shutter has been used as the electronic shutter mechanism in CMOS image sensors; therefore, unavoidable intrinsic distortion of the focal plane occurs.
The existing CMOS image sensors have a rolling shutter as the electronic shutter function; therefore, flash band phenomenon was inevasible in principle.
One major benefit of Pregius is high quality imaging at high speeds. This enables high speed, high precision, machine vision based image scanning of the production line, which significantly improves productivity. This technology also increases the efficiency of image scanning by specifying and recording a partial area of the screen to further improve production efficiency.
Sony offers an extensive lineup to cover various meeds such as industry, public infrastructure, and video recording.
The newly developed Pregius S includes a back-illuminated structure to reduce the size of image sensors and improve frame rates while still maintaining the high imaging performance of Pregius. This new technology improves production line efficiency even further.
The back-illuminated structure and Pregius global shutter pixel technology enables miniaturization of image sensors and faster operation while maintaning high quality imaging. Utilization of lamination technology also enables expanded functionality.
