Ultra Wide Dynamic Range

To understand the meaning of the UWDR, you need to understand the relevance of 'Dynamic Range' as such. The dynamic range (also known as exposure range or light sensitivity range) defines the ratio of the luminosity of the brightest colour (white) to that of the darkest colour (black) that a system is capable of producing.

With Digital Image Capturing the Dynamic Range is one of many evaluation standards for the qualification of Image Sensors. The Wide Dynamic Range describes the ration of a maximal, not saturated signal compared to the standard deviation of the noise at darker lighting conditions. Or, in general, the dynamic range is the ratio between the brightest and the darkest image a camera could capture.

An Image sensor with a higher Dynamic Range is able to capture a higher bandwidth of ambient light than a sensor with a low Dynamic Range. The wider the range, the more detail can be captured and the better is the contrast ratio in shadowed and highlighted areas of an image.

'Ultra Wide Dynamic Range' (UWDR) means a considerably expanded Dynamic Range and so implies a potential extensively higher picture quality. With UWDR the Cam_inPIX^® technology with its CMOS sensors can implement a great differentiation of colour and a much better signal-noise-ratio. The whole colour spectrum is displayed in a lifelike manner. So no coloured edges appear, meaning no colour space shift occours. This applies to very bright areas as well as to shadows.
