Wide Dynamic Range Low Light Level Cmos Image Sensor

The system works as follows.

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. Cameras with wdr technology have advanced sensors that can produce a wider range of lighting allowing them to record in a higher light depth. Wide dynamic range cmos image sensor.

Spi is dedicated to provide high definition hd ultra low light sensors for a wide variety of medical and military applications. The ongoing development of low light level lll cmos image sensor cis technology is rapidly advancing and evolving. 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. Cameras have problems with underexposed and overexposed images because they can only accurately record the middle area of light between very dark and very bright.

A unit sends out a short laser pulse that illuminates. The new design also offers a wide dynamic range and is equally effective in responding to very bright light. Current attempts to reduce the leakage current rely on costly process modifications.
