Abstract: A table type display device, in which a high resolution display with an unremarkable connection is realized at the time of large screen display by using a screen with a composition having few bending is described. In a table type display device comprising plural M of projectors 1L, 1R for projecting luminous flux to form an image, plural N of reflection mirrors 2L, 2R for bending optical paths of luminous fluxes projected from respective plural M of projectors 1L, 1R, screen 3 of horizontal installation type for projecting luminous fluxes for which optical path is bent, by the plurality N of reflection mirrors 2L,2R onto the predetermined region, respectively, the screen comprises a transparent base member 7 for reducing flexure of the screen, optical sheet 9 substantially for making luminous fluxes projected respectively from the plural M of projectors 1L,1R uniform, and a diffusing screen for imaging the image.

Abstract: A table type display device capable of selecting the best projector according to user's budget and mode is provided for with easy exchange of the projector. The table type display device comprises four projectors 1LU, 1LL, 1RU, and 1RL for projecting luminous flux to form image, reflection mirrors 2U and 2L for bending an optical path of luminance flux projected from each of these projectors, and a screen 3 of horizontal installation type for projecting luminous flux with its optical path being bent by reflection mirrors 2U and 2L, onto predetermined regions respectively. The screen housing portion 4b of the main body unit 4 accommodates the screen 3, the reflection mirrors 2U and 2L, and the light shading plates 6LU, 6LL, 6RU, and 6RL, and the projector unit housing portion 4a of the main body unit 4 accommodates projectors 1LU, 1LL, 1RU, and 1RL housed by the projector unit 5.

Abstract: A calibration camera device for geometrical correction or color correction, including a camera mechanism containing a lens, a near-infrared light cutting filter and an imaging element, an optical filter mechanism with three through eight optical filters which is provided in front of the lens, a filter switching mechanism to select any one from among the optical filters and dispose the selected one optical filter at a photometric point, an external cover having an opening formed in front of the lens and covering the optical filter mechanism, the filter switching mechanism and the camera mechanism, an dustproof transparent member to be attached to the opening of said external cover, and a controller which includes an image storing part to store an image captured by the imaging element and a correction information generating part to generate correction data on the image.
