Method in which a component image associated with a primary color of green hue is processed in a suitable manner to reduce the spatial frequencies corresponding to the transition zones in this component image and in which a plurality of component images including the processed component image are successively displayed. Thanks to the invention, the color break-up defects are noticeably reduced. The invention applies especially to anti-piracy image display methods.
