SONY CMOS Image Sensor Technology Guide
The STARVIS™ is back-illuminated pixel technology used in CMOS image sensors for surveillance camera applications. It features a sensitivity of 2000 mV or more per 1 µm2 (color product, when imaging with a 706 cd/m2 light source, F5.6 in 1 s accumulation equivalent), and realizes high picture quality in the visible-light and near infrared light regions.

The Pregius™ is global shutter pixel technology for active pixel-type CMOS image sensors that use Sony’s low-noise CCD structure, and realizes high picture quality. 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. Sony has incorporated Pregius, a global shutter function, into the CMOS image sensor to meet customer needs.

Polarsens is a CMOS Image Sensor pixel technology that has several different angle polarizer formed on chip during the semiconductor process allowing highly accurate alignment with pixel.

Sony’s Image Sensor Exmor R is the back-illuminated CMOS image sensor with improved sensitivity and noise reduction - the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. It has retained the advantages of CMOS image sensors such as low power consumption and high-speed operation.
The key to increased speed of Sony’s CMOS Image Sensor Exmor can be found in parallel signal processing. CMOS image sensors have analog-digital (A/D) conversion circuits that convert analog pixel signals into digital signals. Speed is increased by arranging thousands of these circuits in a horizontal array and allowing them to operate simultaneously.
