CMOS image sensors for network security cameras

A high sensitivity, high resolution 8.48Mpixel CMOS image sensor that supports 4K video cameras has been announced by Renesas Electronics.

Suitable for network security cameras in financial institutions, transportation systems and commercial establishments, the CMOS image sensor is said to provide functions appropriate for imaging under the varied environmental conditions required by high end devices and to contribute to increased system performance.

According to the company, the RAA462113FYL achieves clear, high visibility full colour imaging even in a moonlit environment and can capture clear images using digital zoom whilst supporting high reliability 4K video at 60frame/s.

The sensor supports a line-by-line high dynamic range mode in which long exposure data and short exposure data are output separately for each line. This is said to allow video capture, even for high contrast scenes.

The company also provides a reference board that was developed together with a camera module manufacturer to allow users to evaluate the performance of the CMOS image sensor.
