Emulating Continuously Varying Frame Rates: A Cinematographic Revolution

Ref-Nr: TA-WuT_2015/03


Kurzfassung

A novel filtering technique enables emulating the whole spectrum of presentation frame rates on a single-frame-rate display. The key component of the technique is a set of powerful filters giving an impression of continuously varying presentation frame rate both in the spatial and temporal dimension.


Hintergrund

The visual quality of a motion picture is significantly influenced by the choice of the presentation frame rate.

Problemstellung

Due to the inherently discrete nature of the acquisition and presentation process, distortions of the motion often become apparent. Increasing the frame rate improves the clarity of the image and helps to alleviate many artifacts, such as blur, strobing, flicker, or judder. These benefits, however, come at the price of losing the well-established film aesthetics, often referred to as “cinematic look”. Current technology leaves artists with a sparse set of choices, e.g., 24fps or 48fps, limiting the freedom in adjusting the frame rate to the artistic needs, content, and display technology.


Lösung

Our novel filtering technique enables emulating the whole spectrum of presentation frame rates on a single-frame-rate display. The key component of the technique is a set of powerful filters giving an impression of continuously varying presentation frame rate both in the spatial and temporal dimension. The inventive technology provides film makers with a fine-grained control of not only the overall but also the local film appearance, allowing the best balance between the aesthetics and the objective quality (motion smoothness) of motion pictures. The technique informed by cinematic guidelines can adapt to the content and achieve this balance automatically. From a consumer’s point of view, the technology implemented on a TV display device allows to adapt the reproduction of moving images according to his or her individual, customized preferences in terms of an optimal perception.


Vorteile

  • full variability of presentation frame rate in spatial and temporal dimension
  • no limitation by native frame rate of the displaying device
  • best balance between aesthetics and quality of motion picture
  • reduction of artifacts such as flickering or judder related to low frame rates

Anwendungsbereiche

post-production for the movie industry, film makers, editors, cinema projectors, home cinema
