Wide Dynamic Range Low Light Level Cmos Image Sensor

Spi is dedicated to provide high definition hd ultra low light sensors for a wide variety of medical and military applications.

Wide dynamic range low light level cmos image sensor.

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. Cameras with wdr technology have advanced sensors that can produce a wider range of lighting allowing them to record in a higher light depth. Khana new wide dynamic range cmos pulse frequency modulation digital image sensor with in pixel variable reference voltage proceedings of 51st midwest symposium on circuits and systems knoxville usa 10 13 august 2008 pp. The system works as follows.

Wide dynamic range cmos image sensor. How wide dynamic range works. The ongoing development of low light level lll cmos image sensor cis technology is rapidly advancing and evolving. Current attempts to reduce the leakage current rely on costly process modifications.

A unit sends out a short laser pulse that illuminates. Oxford researchers have developed a new circuit design to allow cmos image sensing at very low light intensities. The new design also offers a wide dynamic range and is equally effective in responding to very bright light.
