<p>The method enables transparent image encrustation on the screens of visual display consoles (7) controlled by graphics processors, these processors being connected to several memory planes of a graphics memory (9) to store the luminance and chrominance attributes of the image points. It consists in reserving, in the memory (9), an additional memory plane to store transparency attributes which can be assigned to each image point to enable the modification of the totality of attribute values stored in the graphics memory and relating to each point of the image to be encrusted as a function of the value of its transparency attribute stored in the additional memory plane. Application: encrustation of television images. <IMAGE></p> |
