Sharp sets benchmark for sensitivity of CCDs for security cameras

With 3,200 mV the new CCD sensors RJ2311CAOPB and RJ2321CAOPB feature the highest sensitivity currently available on the market enabling security cameras to render clear images even under poor ambient light conditions.

Introducing the two new CCD sensors Sharp again raises the benchmark for high performance imaging devices. Both CCD sensors - type RJ2311 CAOPB and RJ2321 CAOPB - feature a sensitive of 3,200 mV which is the highest currently available on the market for security camera CCDs. Thanks to Sharp's proprietary micro-finishing technology which derives from experience of higher resolution compact digital cameras, the collecting incident light ratio and photoelectric conversion efficiency has been significantly improved, resulting in approximately 1.6 times higher sensitivity compared to previous models. In addition, these CCDs are able to obtain higher quality images by reducing the smear ratio to a level of -130db, minimizing smear effects which occur through intense light, such as headlights at night. Furthermore, the increased level of the saturation voltage to 1,200 mV ensures high image dynamics also enhancing the light/dark contrast. Thanks to their industry leading characteristics the new CCDs sensors are predestined für security camera systems to render clear images even under poor light conditions as they occur at night. This is essential for 24h surveillance e.g. of traffic, public spaces and the outside of building requiring special protection.

Both sensors have an optical format of 1/3 whereas the RJ2311 CAOPB has aresolution of 270,000 pixel providing a NTSC signal while the RJ2321 CAOPB delivers a PAL signal with a resolutions of 320,000 pixel.

Availability

Samples of the new RJ2311 CAOPB and RJ2321 CAOPB are available. In addition Sharp provides also high¬performance CCD peripherallCs and system LSls for signal processing, and has actively pro¬moted the development of a wide variety of system solutions for higher-quality cameras.
