Abstract: Viewers of stereoscopic three-dimensional (3D) imagery can perceive the absolute size of objects within a scene. On larger screens, the perceptual size of objects commonly appears bigger than reality, which matches viewers’ expectations for big-screen, larger-than-life theatrical experiences. In contrast, the geometry involved in stereoscopic imaging can cause the perceptual size of objects to appear smaller than reality (miniaturization). Miniaturization can be distracting for viewers and is more extreme on smaller screens like 3D television and handheld 3D devices. A common misconception is that miniaturization occurs only when the stereo camera separation (interaxial) is larger than the human eye separation (interocular), or larger than 2.5 in. In this paper, counter examples of this misconception are provided, as well as an analytical framework that allows stereo camera operators to accurately predict what the miniaturization effect will be on any screen size. Example stereoscopic 3D images are shown to illustrate control of perceptual size.

bio
Michael D. Smith is a consultant working in the areas of digital imaging, signal processing and intellectual property, with recent work for organizations including Warner Bros., Sony Pictures Entertainment, other Hollywood studios and National Oceanic and Atmospheric Administration (NOAA). In addition to his technical work, Smith also performs intellectual property consulting related to infringement and validity analysis of patents. From 2008–2013, he worked on several patent cases for TiVo that resulted in verdicts, judgments and settlements totaling $1.6 billion. He has also worked on matters for other clients including Research in Motion, DivX Networks, Thomson, Polycom, MTV Networks, Citrix Systems and SportVision. His intellectual property consulting often involves computer software source-code analysis and the search and analysis of prior art. Smith was editor of the book “3D Cinema and Television Technology: The First 100 Years” published by SMPTE in 2011. He received the B.S. and M.S. degrees in electrical engineering from UCLA in 2001 and 2004 respectively. Smith can be contacted at miksmith@miksmith.com.
