![]() Sony Pregius Sensors are a manifestation of technology wonders in order to meet customer’s needs. Sony incorporated a global shutter function into CMOS image sensors and labelled it as Pregius Sensors. Until the discovery of Sony global shutter sensors, CMOS image sensors have been using a rolling shutter as the electronic shutter mechanism which led to inevitable intrinsic image distortion. This global shutter pixel technology utilizes low noise CCD structure for realizing high image quality. It is developed for active pixel-type CMOS image sensors and has superiority than other CMOS sensors in terms of better dynamic range, higher saturation capacity, low noise and higher Quantum Efficiency percentage. Sony Pregius Sensors represent the latest pregius technology that is developed for CMOS image sensors to provide excellent image quality. They are the first global shutter CMOS sensors combined in a new analog pixel architecture providing the benefits of both CMOS and CCD sensors. Similar to CCD sensors, this technology aids in providing high saturation capacity, high dynamic range and low temporal dark noise to deliver world class imaging results. Moreover, Pregius sensors also enfold digital advantages of CMOS sensors in terms of high speed, image correction and analogue to digital conversion(ADC) methods. Pregius sensors affords twice as much sensitivity than normal front illuminated sensors by utilizing back illuminated technology. While adhering to correlated double sampling technique(CDS), these sensors overcome temporal dark noise by using dual analogue to digital conversion methods (ADC). Sony pregius CMOS sensors, outperform than any other sensors in the market by providing high dynamic range to increase the visibility of dark and bright areas without causing image saturation. They also offer higher Quantum efficiency implying better conversion of photons into electrons. Moreover, they also deliver low temporal dark noise allowing for more signal gain to generate noise-free image. The Sony Pregius sensors family of sensors are offered in various resolutions ranging from 1.5 MP to 12MP, in order to realize high image quality for different applications.
