Noise-reducing a color filter array image

摘要

A method of reducing noise in a color filter array encoded image, comprising using an image sensor having a color filter array to capture an image of a scene and using such capture image to provide a color filter array encoded image; low pass filtering the color filter array encoded image to provide a base image and using such base image and the color filter array encoded image to provide a residual image; processing the base image to provide a full color fully processed base image; converting the residual image using color filter array interpolation to provide a full color residual image; and combining the full color fully processed base image and the full color residual image to provide a noised reduced fully processed image.
