Abstract
A method and user interface for direct setting of black and white points. Black point is set using a slider and matching of gray shades. White point setting is performed by having a setting object move within a defined region, such as a square or circle, with the area where the setting object moves being adjusted dynamically based on the location of the setting object with respect to the defined region. When the area is the desired white, the setting is complete. Preferably the defined region has a varying color border to allow a reference for the user in moving the setting object. A more detailed setting of gray levels can be accomplished by providing a gray scale with reference points. Each reference point has an associated white point setting area, so that settings are developed for each reference point. Settings at other locations are determined by interpolation or extrapolation.
