Abstract
Systems for processing pixel signals generated by an image sensor to create improved images. More particularly, systems and methods are disclosed that adjust the gain on, inter alia, a pixel-by-pixel basis, to improve the dynamic range of the imaging system. The systems may include level detectors that measure the amplitude of a pixel signal and, based on that measurement, amplify that pixel signal by an amount that allows certain subsequent processing of the pixel signal to be more accurate. More accurately processed pixel signals can provide better overall images.
