Abstract
In certain low-light or other poor image capture conditions, the camera capture settings may create noise fitting a known profile, including certain specific color ranges and signal frequencies, in the captured image. A pre-processor may identify frequency bands and DC offsets that may indicate noise in an image captured with known settings. Then the areas of the image containing the identified frequencies and offsets may be analyzed spatially and temporally to confirm that the identified regions are noise and not part of the scene and an appropriate filter defined.
