STARVIS sensor¶
Sony STARVIS sensor is a back-illuminated pixel technology use in CMOS image sensors for security camera applications providing high picture quality in the visible-light and near-infrared light regions.
There are two versions STARVIS and STARVIS 2. STARVIS 2 is similar to STARVIS but it also has a wide dynamic range (AD12bit) of more than 8dB compared to STARVIS for the same pixel size in a single exposure and achieves high picture quality in the visible-light and near-infrared light regions.
What is a back-illuminated CMOS sensor?¶
With a back-illuminated sensor, the light is collected by the backside where the obstacle like wires are minimum all the photo-diode receive a wider range of light which translate in high sensitivity

What is DOL-HDR?¶
The DOL-HDR or Digital Overlap High Dynamic Range is a technology for image processing of subjects with high contrast. It synthesizes different exposure conditions into a single image so that both dark and bright data can be seen at the same time.
