Wide Dynamic Range Low Light Level Cmos Image Sensor

How wide dynamic range works.

Wide dynamic range low light level cmos image sensor.

Tering gated cmos image sensor with linear wide dynamic range wdr implementation which is synchronized with an external active pulsed light source that is intended for a low light high responsivity night vision system. Oxford researchers have developed a new circuit design to allow cmos image sensing at very low light intensities. The ongoing development of low light level lll cmos image sensor cis technology is rapidly advancing and evolving. The new design also offers a wide dynamic range and is equally effective in responding to very bright light.

The system works as follows. Current attempts to reduce the leakage current rely on costly process modifications. A unit sends out a short laser pulse that illuminates. Spi is dedicated to provide high definition hd ultra low light sensors for a wide variety of medical and military applications.

A wide dynamic range cmos image sensor is proposed exhibiting a linear response at a low illumination level and a logarithmic response at a high illumination level. A wide dynamic range dr pixel level cmos image sensor with self reset technique has been fabricated using a 0 18 mum six metal cmos technology and tested to verify simultaneous increase of both. Cameras with wdr technology have advanced sensors that can produce a wider range of lighting allowing them to record in a higher light depth.
