Fog, mist and glare significantly reduce image contrast and can make recognition (or even detection) nearly impossible. The advanced processing power of 15-bit DSPs provides significant improvement in contrast by increasing the scope of the camera's dynamic range.
Using XF-Dynamic's Auto Black function, Bosch's DinionXF camera dynamically stretches the illumination levels in scenes to reduce the darkest areas to (near) black. This function enhances contrast in pictures obscured by veiling glare or in which contrast is reduced by fog or mist. The Auto Black function is the most effective in indoor situations, such as a nightclub with low light and cigarette smoke.
