Method and apparatus for maximizing the visual quality of image presented in electric form

摘要

The present invention relates to a procedure and an apparatus for optimizing the visual quality of an image. In the procedure, the greyness balance of the image is adjusted by a statistical method and the color reproduction is adjusted to make it correspond to a standard observer's preference, which is a predetermined optimum value for color reproduction. The procedure can be used e.g. to improve the quality of images transmitted over information networks by providing the image transmission path with an apparatus which corrects images detected in the transmission path by applying the procedure of the present invention.
