摘要

A method of processing an image comprises, if the part of the image has been determined to represent human skin applying a first noise reduction process to the part of the image, or, if the part of the image has been determined not to represent human skin, applying a second noise reduction process to the part of the image, the first noise reduction process giving an image with a higher noise and/or texture content than the second noise reduction process. The additional noise/texture present, after processing, in a part of the image that is determined to represent human skin effectively acts as a substitute for natural skin texture which may have been lost during the image capture and transmission process. The method may be applied to a still image, or to a sequence of images such as a video image.
