Abstract: This paper describes a new method of creating special effect images, emphasizing the subject of interest in video. These special effect images are created so that background regions are blurred while the resolution of the subject-of-interest region remains unchanged. The paper describes how the above images can be easily obtained by using motion vectors and temporal filters. This resolves some problems inherent in more conventional methods. Second, a method for blurring the subject of noninterest is proposed, using the same motions used for the subject of interest. When temporal filtering is applied to patterns where the difference in motion tends to change between the subject of interest and the background region, the resolution of the background region tends to fluctuate with variation in motion, and this could produce a disagreeable dizzy sensation in viewers. Finally, a method is proposed for mitigating these effects caused by variation in the resolution of the background, due to differences in motion between the subject of interest and the background region.
