  • Patent number: 9989777
    Abstract: A display system that is particularly well-suited for use in providing or displaying a live cinematic performance to an audience. The system includes a first space that is directly viewable by the audience and that is illuminated with a stage lighting assembly. Human, robotic, or other physical performers are positioned in the first space and selectively illuminated by light from the stage lighting. The system includes a Pepper's ghost assembly configured to provide enhanced brightness of the projected image as background items in the Pepper's ghost assembly's space are hidden from view by the audience. The Pepper's ghost assembly may include one or more high speed projectors or other light sources, a high speed vision system, and black retroreflective material, and these components function in combination to allow the assembly to be operated to selectively light objects and people in the hidden space without projecting the background to the audience.

  • Patent number: 9936174
    Abstract: In a case where an image forming panel is disposed to be shifted with respect to an optical axis of a projection lens having a lens barrel holding the lens, in the lens barrel, the increase in temperature in a first part on a side to which the image forming panel is shifted is larger than that in a second part on an opposite side. A temperature adjustment section includes a cooling duct, a heating duct, a connecting duct, and blowers 27 and. Air, which is suctioned from an inlet of the cooling duct, is passed through the first part, a light source, and the second part, sequentially by the blowers. The air cools down the first part, and heats the second part. Thereby, the temperature distribution in the circumferential direction of the lens barrel becomes uniform, and deterioration of the projected image is suppressed.
