High-sensitivity sensor for improved video surveillance
Available from specialist distributor Framos (Taufkirchen, Germany), the IMX327 reaches a frame rate of 60fps at 12 bits. With high sensitivity and very good low light performance, this sensor suits security and surveillance applications as well as factory automation and industrial designs.
The IMX327 uses Sony’s STARVIS technology with back-illuminated pixels in a CMOS sensor providing a sensitivity of 2376 mV/µm² which is combined with an SNR1s of 0.18 lux, making this sensor perfect for tracking and monitoring under low light conditions (SNR1s is a Sony proprietary index and is limited to their security sensors). The sensor delivers high image quality in the visible light and near infrared light spectra. High sensitivity, low dark current noise and no smear are characteristics of this sensor that provide excellent image reproduction and, when combined with improved RGB colour mosaic filters, excellent colour reproduction with little to no additional processing. These chips feature an electronic rolling shutter with variable charge-integration time that allows more flexibility in capturing precisely illuminated snapshots.
To further enhance the image quality provided by the IMX327, Sony includes a High Dynamic Range (HDR) feature, with multiple exposures and digital overlap HDR. An anti-reflective coating version is available to enhance light transmission through the sensor cover glass, achieving even higher performance with a sensitivity of 2519 mV µm² and SNR1s of 0.17 lux. The sensor has low power consumption, supports I/O switching and provides LVDS or MIPI CSI-2 output interfaces. Evaluation samples are now available, with mass production planned for Q1 2018.
