Verfahren und Vorrichtung zum dekodieren von Bildern und Datenaufzeichnungsmedium

摘要

An image decoding method for decoding compressively coded data including coded data obtained by coding a luminance signal and a color difference signal to reproduce an image signal for image display, comprises the steps of: decoding the coded data of the luminance signal and the coded data of the color difference signal in the color display mode of color display of an image; and decoding the coded data of the luminance signal in the monochrome display mode of monochrome display of an image. <IMAGE>
