(High dynamic rank CMOS) is a new technology within the range of CMOS image sensors. - Sensors are particularly efficient when the used under extreme light conditions (over and Unterbelichtung) as also with strong back light. Contrary to conventional CMOS sensors and CCD sensors the output voltage of HDRC sensors is not a linear function of the light intensity, but a logarithmic function of the intensity. This behavior resembles the sensitivity of the human eye (weber Fechner law).

In HDRC cameras for each pixel (pixel) the photo-sensitive element (a photodiode) with a CMOS field-effect transistor is combined, in order to receive the light intensity a proportional signal. Since the characteristic of the Logarithmierung from pixel varies to pixel (offset voltage), must a correction picture of an evenly bright surface from the actual picture is subtracted. This procedure is similarly the white picture correction with conventional image sensors, because of the logarithmic connection with the HDCR sensor however subtracted instead of is divided.

HDRC sensors are for example for black-and-white monitoring cameras and suitable for applications in the traffic very well (insensitively to glare by headlights).
