Image enhancement method utilizing pixels of an input image in a YUV color space

摘要

Disclosed are an image enhancement method and an image enhancement apparatus which can realize the edge enhancement for an image generated after a demosaicing process according to local characteristics of an input image (i.e. the image sharpening) and can realize the brightness noise suppression and the chroma noise suppression for the image. Thus, by using the image enhancement method and the image enhancement apparatus provided by the present disclosure, clear images can be generated.
