Abstract
The invention relates to computer graphics and computer imaging on a video display, and includes the dynamic detection of video windows and graphical images overlapping one another. A display processor identifies differences between typical video and graphics data sources to detect the edges of video windows. By detecting the edges of active video windows within a graphics image, a display processor may uniquely adjust image characteristics of an exposed video window. These characteristics include, for example, hue, brightness, intensity and contrast.
