An apparatus and method for scaling-up a set of video data uses variations in the black-and-white components, of a graphic image to better generate "missing" color components in an image. The location of large variations in the black-and-white components of an image, or edges in the black-and-white portion of the image, may be used to generate the missing color components. The variations in the black-and-white components of an image, around a particular location in the image, provide additional information for interpolating between the more widely spaced color component information. The method and apparatus allow for the selection, and adjustment to, the weights given to edge locations. The method and apparatus may be used as part of a computer system to expand and display compressed graphic data.
