This paper describes a new method to create sequences with special video effects, emphasizing the primary impression of the images. These special effects are produced so that background areas are blurred while the resolution of the main image remains unchanged. We show how the above sequences can be easily obtained by using motion vectors and temporal filters. This resolves some problems inherent in more conventional methods. Secondly, we propose a method for blurring the background using the same motions used for the main image. When the motion differences between the main portion and background areas vary, the resolution fluctuations can make the viewers feel uncomfortable. Finally, we propose a method to reduce resolution fluctuations in the background areas.
