Abstract:
Methods and corresponding apparatus are presented that perform dynamic range compensation (DRC) and noise reduction (NR) together on a pixel-by-pixel basis, adjusting the noise reduction parameters in response to the dynamic range compensation decisions. By such a modification of image noise reduction parameters based on the dynamic range compensation gain or, more generally, other such factors, these techniques make it possible to perform DRC on noisy images, achieving an image with low and uniform noise levels.
