Security Camera Image Sensor

Security camera image sensors equipped with STARVIS™ / STARVIS 2 technology, to capture clear images regardless of brightness

Overview

Cameras are in great demand in various applications today to make society safe and secure, ranging from facility/street surveillance and detection of irregular activities to traffic monitoring, home security, and drive recorder systems. Sony Semiconductor Solutions Corporation(SSS) offers a rich lineup of image sensors supported by low-luminosity imaging technology (low noise/high sensitivity), capability to capture images under various lighting conditions (high dynamic range), etc., making contributions to the security area.

Features

CMOS image sensors with outstanding levels of low noise and high sensitivity performance

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.

HDR technology that can accurately capture images regardless of brightness

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.

High-quality imaging characteristics in the near infrared (NIR) region

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.

*1: SNR1s is a proprietary index tailored to quantitatively evaluate image quality at low illuminance, which Sony has developed specifically for CMOS image sensors for security applications. See What’s SNR1s? for more details.

*2: HDR (High Dynamic Range) is a feature that uses finer chromatic gradation for image rendering to depict more details in the over- and under-exposed regions that occur in the same image. See “High Dynamic Range (HDR) Feature” to learn about the difference between DOL HDR and Clear HDR.

*3: NIR stands for the capacity to capture images in the near infrared spectrum. This feature realizes image capturing even in a pitch-dark location by the use of near-infrared light. Sony offers NIR imaging in all of the models below, meeting the needs in diverse applications. Furthermore, NIR technology has recently seen remarkable improvement. The identifier “NIR Enhanced (Yes)” indicates that the product is mounted with the enhanced version of NIR functionality. For more descriptions about NIR, see “Imaging Performance in the Near-infrared (NIR) Spectrum”.

What's SNR1s ?

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).

SNR1s [lx] Prescribed Conditions
Application Security Camera
Light Source 3200 [K]
Target Object 18% Grey
F number 1.4
Exposure time 1/60 [s]
Linear Matrix without
Signal G [e-] (Sensor Raw Output)
Noise Noise
Signal : Noise 1:1

Schematic of SNR1s Measurement Method

Two 3200 [K] light sources illuminate an 18% gray chart from different directions, and dimming is performed to 100 [lx]. A camera is placed so that the distance from the gray chart to the imaging surface of the image sensor is 1 m, the sensitivity [e-] and dark noise [e-] are measured, and SNR1s [lx] is calculated using the relational equation (1). The luminance when equation (1) equals 1 is SNR1s [lx].
For further details, contact your local Sony's sales company.

The SNR1s value (SNR1s [lx]) of CMOS image sensors for security applications indicates better image quality at low illuminance the lower its value. For SNR1s values of individual product types, refer to our Product Lineup.

*) SNR1s is a new index proposed by SSS for picture quality at low illumination, and is limited to CMOS image sensors for security applications.
SSS reserves the right to change SNR1s values without prior notice.
SSS cannot assume responsibility for any phenomena occurring as a result of using released SNR1s values.
