  • Adaptive sensitivity control, on a pixel-by-pixel basis, for a digital imager
    Publication number: 20020105581
    Abstract: A system and method adaptively control sensitivity, on a pixel-by-pixel basis, of a digital imager. An illumination intensity level mapping controller determines a number of pixels of image data having illumination intensity levels within a first defined range of illumination intensity levels and determines an illumination intensity level mapping function based upon the determined number of pixels within the first defined range of illumination intensity levels. An exposure controller determines a number of pixels having illumination intensity levels within a second defined range of illumination intensity levels and determines an integration time based upon the determined number of pixels having illumination intensity levels within the second defined range of illumination intensity levels.
