R67 projects, for example, image data of a screen frame of a general moving image that is reproduced by normal image software (or home-made image software) by fixing and moving the fixed video projector 40 and the movable video projectors 36 and 37.
It is synthesized with the projected image from the SP35 and displayed as an image in every part of the sky, in a double or triple layer, or as a large screen assembled. As a result, ordinary software can be used and the whole sky screen can be displayed in a stereoscopic effect, which is low cost, and the range of selection of video software is widened, giving a high degree of freedom in stereoscopic image production. Can be realized on the whole sky screen.

By the way, when synthesizing the projected images of the fixed video projector 40 and the movable video projects 36 and 37 on the background projected image from the SP 35, it is not preferable to visually recognize these screen frames, so that the video image The brightness and color gradation must be adjusted so that the screen frame does not appear. Therefore, it is possible to avoid visually recognizing the display of the moving picture frame by dropping the black on the projection screen and aligning the gradation with the black of the background.

Then, returning to FIG. 3, the main controller 51 appropriately displays SP2 according to the operating time.
