Abstract
Embodiments of the present invention blend frames over a specified temporal window to produce a smooth appearance at a reduced frame rate. As the window moves further or closer to the viewer, motion blur may be accomplished by temporal averaging. In particular, the temporal average is used to blend image information for a predefined/brief interval before and after the time of the output frame, retaining all of the image information, but in a slightly blurred form. After the relevant image information is retained, frames may be displayed at a reduced output rate while retaining sufficient information to reproduce a smoothly moving animation sequence.
