Abstract
Embodiments of the present invention blend frames over a specified spatial and temporal extent to produce a smoothly animated appearance at a reduced frame rate. As the window moves further or closer to the viewer, motion blur may be accomplished by a combination of spatial and temporal averaging. Spatial averaging is used in conjunction with temporal averaging to reduce the rate at which images, including desktop images, are composed and to reduce the amount of graphics memory bandwidth needed for the composition.
