Report Finds 3D Ghosting Has Many Causes

The Cinema Technology Community has published a report about the causes of 3D crosstalk. According to the not-for-profit independent cinema technology organization, while no single piece of equipment (port glass, projector, 3D system, 3D screen and eye wear) is necessarily responsible for the introduction of 3D ghosting, any and all elements in the light path can have a contributing effect inside of a closed ecosystem. 

The research also suggests that, although content itself does not inherently contain ghosting, the way in which it is created and mastered can, when shown in certain ecosystems introduce ghosting through crosstalk inherently in the light path of projection and 3D equipment.

According to the report, CTC believes that it is incumbent upon cinema exhibitors to ensure that they are operating regular maintenance programs to ensure that all equipment is in good working order and where necessary work with their integration partners or product manufacturers to identify faults where these occur. It is also essential that content creators have a strong understanding of real-world cinema conditions and are testing 3D content in a variety of environments prior to release to ensure that content seen during the post-production process is replicated inside of commercial cinema environments.

“By raising awareness of this issue, CTC believes it can provide a forum to bring the industry together and hopefully help to ensure that movie-goers throughout the world have the best possible 3D experience,” said CTC president Richard Mitchell. “Beyond this report, CTC aims to continue to investigate this topic with partners in exhibition and distribution with a view to continuing to provide knowledge-sharing for the wider industry.”

CTC’s report on the Causes of 3D Ghosting is available to CTC members via the exclusive members content area on the web site.
