This disclosure pertains to novel devices, methods, and computer readable media for performing color defringing on image data. In photography, particularly RAW images, different artifacts can affect the quality of the edges of objects in the image. This effect is generally more noticeable when the edge has high contrast. One motivation for the described techniques is the understanding that, typically, not all pixels of an image exhibit color fringing. Usually, fringing only occurs in high-contrast edges. Mere masking of the effects of the whole-image operations can improve the result, but further improvements are still possible. This disclosure also pertains to novel devices and computer readable media for performing red-blue color reconstruction on data from a variety of color filter arrays (CFAs).
