What's Sony Starvis?
Starvis = Star + visibility, it's the latest low light CMOS imaging technology from Sony Corporation. Based on this technology, Sony released STARVIS CMOS image sensors product portfolio. The Starvis technology can increase the sensitivity of existing Exmor-R CMOS image sensors for night vision security cameras. When utilizing the Starvis CMOS image sensor, the security camera can see objects clearly at night although doesn't need to use artificial lighting (infrared illuminators), therefore can greatly reduce the power consumption, brings you super-low power consumption security cameras.
According to Sony's whitepaper, the Starvis technology can use light more efficiently over a wide range of wavelengths, to enhance sensitivity not only in the visible light region, but also the near infrared light region that is often used by security cameras. The sensitivity of Starvis CMOS image sensors can achieve 2,000 mV or more per 1μ㎡ pixel size,which is two times higher than the sensitivity of the existing Exview HAD CCD image sensor.
From June 2015, Sony commenced mass production Starvis CMOS image sensors including IMX290 (2 megapixel), IMX123 (3 megapixel), IMX224 (1.3 megapixel) models. As network security cameras are usually installed for day&night video surveillance, so they are used with the lens aperture fully open in many cases. Intending to improve the light sensitivity, the Exmor-R structure adopted by Starvis doesn't have a wiring layer that blocks incident light above the light above the photo-diode, dramatically increasing the light utilization efficiency.
