ABSTRACT:
A flicker reduction system for display of computer graphics on an interlaced display is provided. Under the control of a computer or game system, horizontal lines are analyzed to determine if flicker conditions are present. If flicker conditions exist, a horizontal line may be constrained to occupy a certain field depending on the location of the graphical object relative to other graphical objects. Analyzing flicker conditions allows a flicker-free display to be created without unnecessarily reducing resolution of the display. The flicker conditions may be analyzed whenever a new graphical object is created or when an existing graphical object is moved. Additionally, all horizontal edges may be constrained to being displayed in the same field to reduce flicker.
