Olympus Announces Development of New Vision Plex High-Fidelity Display Technology
New technology provides seamless high-fidelity display of output from up to 68 SXGA projectors
* Information in this news release applies to the Japanese market only.
Olympus Optical Co., Ltd. (President: Tsuyoshi Kikukawa) is pleased to announce the development of a new Vision Plex High-Fidelity Display system for seamless, large-screen display of output from up to 68 SXGA*1 projectors.
The Vision Plex system is composed of a control unit and its controlling PC, and a calibration camera. Up to four XGA/SXGA projectors can be connected to a single control unit, and the projected images can be seamlessly combined to produce a single high-fidelity image. The new system has a wide range of potential applications in aviation and traffic control, various types of simulators, large-screen digital cinemas and planetariums.
Top Features
Utilizing exclusive Olympus digital camera technology, the Vision Plex system allows distortion, brightness and color to be quickly and easily corrected to produce a single, seamless, large-screen image.
By increasing the number of control units used, a total of up to 68 projectors can be linked together to achieve exceptionally large display sizes. Furthermore, by connecting the newly developed Olympus High-Fidelity Digital Movie Camera Prototype*2 to the system, digital motion video images with a resolution of 8 million pixels can be displayed.
The Vision Plex system can be used with flat, curved, and dome-shaped screens, allowing it to be adapted to meet a wide range of customer needs.
In the future, additional research will be conducted to assess how Vision Plex technology can be further refined to meet customer needs.
*1 A commonly used display format with an effective pixel count of 1.3 million.

Development Background
In December of 1999, Olympus developed a ultrahigh-resolution display system that used output from nine SVGA projectors to produce still and motion video images with a resolution of 4 million pixels. After further development, this technology was then applied to the HDPS100 Ultrahigh-resolution Rear Display System, a production model introduced in March 2001 that featured a 100-inch, rear-projection screen. For the next stage of evolution in Vision Plex technology, we sought to respond to customer demand for larger display sizes and even higher image quality by improving system expandability and adding SXGA support.
Main Features
Vision Plex automates all aspects of image calibration by performing the following tasks:
Projects a test pattern generated by the control unit onto the screen.
Photographs the on-screen test pattern with the dedicated calibration camera.
Analyzes test pattern data and performs calculations necessary to correct positioning, distortion, brightness, and hue.
Sends corrected data to the control unit.
Compensates instantly for individual projector characteristics and projects corrected image onto the screen.
The resulting screen image is completely seamless, and because all correction is handled by the control unit, there is never any need to adjust the projectors individually.
Up to 4 projectors can be connected to each control unit, and up to 17 control units can be linked to a single PC for a total of 68 projectors. In addition, the projectors can be freely configured to suit a variety of screen aspect ratios.
The Vision Plex system's calibration accuracy is unaffected by screen format, allowing it to be used with flat, curved, or dome-shaped screens with equal ease.
The Vision Plex system supports both LCD and DLP projectors in SXGA and XGA high-resolution formats. As a result, it is possible to create large-screen, high-fidelity displays with standard off-the-shelf projectors.
A wide range of image source material is supported.
Any still or motion video content that can be stored on the controlling PC (including audio)
Multiple still and motion video content files (different source material for each projector, overlaid on-screen)
External-source broadcast video signal or PC output
Standard broadcast video signals (NTSC, HDTV, etc.)
