STARVIS / STARVIS 2 technology, dedicatedly developed for CMOS image sensors for security cameras, has made it possible to simultaneously demonstrate sensitivity beyond the human eye as well as outstanding low noise characteristics. These sensors can accurately reproduce colors and textures of targets which are difficult to distinguish in dark locations, drastically improving their performance in low-illuminance environments where security cameras are used.
Two type of HDR functions are prepared to assist the security cameras to shoot under complex lighting comditions. DOL HDR is best suited for slow-moving objects and Clear HDR for high-moving objects. The installed HDR varies depending on the model. Please check the product lineup.
This series of image sensors are capable of capturing images under the near-infrared light in addition to the visible light. By emitting near-infrared light as auxiliary light, they can clearly capture the shapes and the gradation of the objects even in "jet-black" darkness.
SSS is introducing SNR1s [lx] as an index used to quantitatively evaluate picture quality at low illumination.
SNR1s [lx] is a proprietary index advocated by Sony, and is limited to image sensors for security camera applications. A smaller value indicates better picture quality at low illumination. SNR1s [lx] is an acronym consisting of "SNR" (Signal-to-Noise Ratio), "1" (represents that the signal level when noise = 1 is 1), and "s" (for Security).
