Abstract: According to the perceptions of the human visual system, optimization of the temporal sampling aperture is required to best convey motion blur during HDTV image capturing. Filtering temporal aliasing artifacts becomes possible with the latest technologies in picture acquisition, and is applicable for advanced tape-based or tapeless recording. This paper presents an analysis of video capturing and recording in HDTV, for the case of variable frame rate (varispeed) acquisition. It proposes an optimization of the exposure duration, so that the duration becomes dependent on the frame rate of the master format. This approach restrains the strobe effect and utilizes motion blur for better rendering of dynamic scenes. The improved overall image quality also benefits the processes of editing, compositing, conversion, and compression. Finally, the research results are integrated into an embedded algorithm to suggest how to implement this strategy.

bio
Emil Borissoff is chief engineer of Toybox Toronto, a division of Command Post & Transfer Corp., which he joined 13 years ago. He has been working in the area of digital video systems and motion imaging. His research interests include 3-D sampling and conversion, compression optimization, dynamic scene artifacts, and HDTV standard limitations. Borissoff received an M.S. and a Ph.D. degree in electronic engineering and image processing from the Polytechnic University of Sofia, Bulgaria, in 1977 and 1987, respectively. He started his career as a broadcast engineer with a TV station in this city, engaged from the beginning with R&D. He moved to Canada in 1991 as a senior post-production engineer. Borissoff has four international patents in the field of video algorithms and has been a member of SMPTE since 1994.
