Nintendo hit with 3DS patent suit over glasses-free 3D

7.11.2011

[Philip Lelyveld comment: This patent (below and linked) could impact many 3D camera mftrs and metadata discussions]

[By: Blake Ellison]

Japanese firm Tomita Technologies has filed a patent infringement suit against Nintendo in the United States over glasses-free 3D as used in the Nintendo 3DS handheld.

The suit, filed in U.S. District Court, alleges that the 3DS infringes on U.S. Patent No. 7,417,664(also known as the ‘664 patent) titled “Stereoscopic Image Picking Up and Display System Based Upon Optical Axes Cross-Point Information.” This patent deals with “technology relating to displaying stereoscopic images on-screen for viewing with the naked eye” which is exactly what the 3DS hardware achieves. The patent was applied for in 2003 and granted in 2008, whereas the 3DS launched in March of this year.

Based on the figure below from the ’664 patent, the claim seems plausible:

However, all the details of the suit have not yet been made clear. The patent appears to cover a complete system of acquiring 3D images using a pair of cameras, a device to determine the proper offset between the two images, and a stereoscopic screen that can display the two images side-by-side. According to Patent Arcade, which spotted the suit, the complaint cites the Sony website to establish that the 3DS achieves its glasses-free 3D by use of two cameras on the device used to take 3D photos. The website adds that the complaint does not establish how the 3DS infringes upon the patent.

Tomita Technologies belongs to Seijiro Tomita, a long-time Sony engineer who retired to found his own R&D firm. If he wins this patent case it could be quite a lucrative licensing deal Nintendo will be forced to create with him.

Nintendo is not one to shy away from a patent lawsuit. Last year, the company won an appeal to overturn a verdict against the Gamecube, Wavebird, and Classic controllers in the notorious Eastern Texas District Court.

Stereoscopic image picking up and display system based upon optical axes cross-point information

Abstract

A stereoscopic video image pick-up and display system having a stereoscopic video image pick-up device including two video image pick-ups for outputting video information from the pick-ups; a stereoscopic video image display device for displaying different video images; and a medium for transmitting the video image information from the stereoscopic video image pick-up device to the stereoscopic video image display device. The stereoscopic video image pick-up device includes a cross-point measuring devi

Specification for Naming VFX Image Sequences Released

ETC’s VFX Working Group has published a specification for best practices naming image sequences such as plates and comps. File naming is an essential tool for organizing the multitude of frames that are inputs and outputs from the VFX process. Prior to the publication of this specification, each organization had its own naming scheme, requiring custom processes for each partner, which often resulted in confusion and miscommunication.

The new ETC@USC specification focuses primarily on sequences of individual images. The initial use case was VFX plates, typically delivered as OpenEXR or DPX files. However, the team soon realized that the same naming conventions can apply to virtually any image sequence. Consequently, the specification was written to handle a wide array of assets and use cases.

To ensure all requirements are represented, the working group included over 2 dozen participants representing studios, VFX houses, tool creators, creatives and others.  The ETC@USC also worked closely with MovieLabs to ensure that the specification could be integrated as part of their 2030 Vision.

A key design criteria for this specification is compatibility with existing practices.  Chair of the VFX working group, Horst Sarubin of Universal Pictures, said: “Our studio is committed to being at the forefront of designing best industry practices to modernize and simplify workflows, and we believe this white paper succeeded in building a new foundation for tools to transfer files in the most efficient manner.”

This specification is compatible with other initiatives such as the Visual Effects Society (VES) Transfer Specifications. “We wanted to make it as seamless as possible for everyone to adopt this specification,” said working group co-chair and ETC@USC’s Erik Weaver. “To ensure all perspectives were represented we created a team of industry experts familiar with the handling of these materials and collaborated with a number of industry groups.”

“Collaboration between MovieLabs and important industry groups like the ETC is critical to implementing the 2030 Vision,” said Craig Seidel, SVP of MovieLabs. “This specification is a key step in defining the foundations for better software-defined workflows. We look forward to continued partnership with the ETC on implementing other critical elements of the 2030 Vision.”

The specification is available online for anyone to use.
