Image processing method and image processing device

Abstract

An image processing method is provided. The method includes a first MCNR stage and a second MCNR stage. The first MCNR stage includes blending the current frame with either a cached image or a long-term reference image to obtain a fused image. The cached image is loaded from the buffer unit, and the long-term reference image is derived from the static region of each input frame in a sequence of input frames. The second MCNR stage includes blending the fused image with the other of the cached image or the long-term reference image to obtain an output image.
