  • Patent number: 5051928
    Abstract: A color correction method for a video graphics system defines a region of color space within which target objects to be corrected lie. The region is defined automatically by positioning a target box within a representative portion of a target object within a video picture and computing from the pixels within the target box a range of color parameters which include the target object. A desired color for the target object is selected, and all pixels which are both within the video picture or a selected portion thereof and also within the defined region of color space are changed accordingly. Anti-aliasing is provided by scanning an area surrounding each pixel to determine the number pixels within the area which are within the defined region, and changing the color of each pixel according to the ratio of the number of pixels which lie within the defined region and the total number of pixels within the area.
