Conceptual Diagram of the System

The demand for sophisticated imaging system technology for ever-larger displays at ever-higher resolutions never ceases. Mitsubishi Electric has therefore developed a Multi-Projector Large-Screen Display System that creates high-quality images by utilizing consumer PCs, projectors and other equipment. Conventional large-screen systems simply enlarge an image from a single output device and project it onto a large screen, which results in the deterioration of image quality. Mitsubishi Electric's new system makes possible a large-screen display that doesn't sacrifice resolution, by splitting the projected images and processing multiple PCs in parallel. Our exclusive technology allows for automatic positioning, brightness control and other adjustments, thus enabling a single seamless image display. What's more, the number of projectors can be scaled up to 100 or more.

One may refer to the Dome-shaped Seamless Multi-projector Display System as an evolutionary model of the Multi-Projector Large-Screen Display System. When projected onto a dome-shaped screen with curved surface, images become severely distorted. Mitsubishi Electric's technology not only ensures a high resolution by splitting the images and projecting them using multiple projectors, but also corrects, in real time, any distortion caused by the use of a curved-surface screen. Thanks to the algorithmic correction function, the burdensome adjustments once required by traditional systems are no longer needed. In addition, high-precision technology for seam correction provides a seamless display of the images that are split and projected. The Dome-shaped Seamless Multi-projector Display System literally is a revolutionary technology that uses consumer PCs and projectors to make 3D graphics more substantial, such as flight simulations with highly realistic sensations.

*The Dome-shape Seamless Multi-projector Display System was jointly developed by Mitsubishi Electric Corporation and Mitsubishi Precision Co., Ltd.

With an objective of thrilling viewers with spectacular images, our development efforts are guided by our policy of placing emphasis on "every single pixel and every single frame." The larger the screen, the more noticeable issues such as minimal delays in movements or distortions of images become. In a multi-screen configuration, even the slightest gap between screens can adversely affect image quality. The development of display systems using larger screens and more numerous projectors is in fact the pursuit of higher display precision. The Multi-Projector Large-Screen Display System is a future-generation technology capable of contributing to the realization of higher-precision displays.

The Multi-Projector Large-Screen Display System enables a free layout of such existing contents as still and moving images, crawls, rolls and animations, realizing original and creative expressions. Also, the Dome-shaped Seamless Multi-projector Display System requires no additional burden of creating the 3D contents especially for dome-shaped displays, as the System accommodates those already in place for flat-surface screens. Additionally, the OpenGL® -compatible CG contents can be shown as is, and real-time imaging display is also available. Contents previously valid for only a single purpose can now be applied to multiple purposes. The Multi-Projector Large-Screen Display System ensures innovative image presentation and visual communication while utilizing already-existing contents.
