Abstract

(57) [Summary] The present invention relates to a method and an apparatus for forming a high-resolution large image on the front 1 of a building. For this purpose, the light passage 3 is illuminated by the projector 5.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a high-resolution large image on a surface, and more particularly to a device for forming it on the front of a building, and to a technique for illuminating a large number of light passage openings by a video projector.

[0002]

[Problems to be Solved by the Invention]

It is an object of the present invention to propose a method and apparatus for forming a high-resolution large image on the front of a building, and to make good use of the surface of such a building for advertising and other purposes. It is an object of the present invention to be able to project a high resolution large image on any face of a building, in particular on the front of the building, with a high quality image.

[0003]

[Means for Solving the Problems]

This problem is substantially solved by forming a part of the image (partial image), preferably by illuminating each light passage opening with one projector.

By using this method, it is possible to form an aesthetically high-resolution large image in all manner.

In a further development of the invention, it is proposed that the light passage opening is the front window. In addition, the light passage opening is conveniently illuminated from the rear side, which is located opposite the front side of the surface, that is, onto the window that is illuminated from the inside to the outside of the room, so that the projector is It is preferably arranged in the rear area or the ceiling area located on the opposite side.

Since achieving good quality images requires a good distribution of light through the entire surface of each illuminated window, it is preferable that the window be substantially opposite the plane. It is proposed to illuminate all windows on the front side of the front by a method of forming partial images. For this reason, in particular, the window is illuminated with a light source using a coating, an adhesive film or a blind.

The device according to the present invention is characterized by comprising a plurality of light passage openings and a plurality of projectors that illuminate the light passage openings, and produces a high-resolution whole image on the front surface of the front surface.

[0008]

DETAILED DESCRIPTION OF THE INVENTION

Further, a control device may be provided to assign partial images to each individual projector. This makes it possible to produce a high-resolution whole image. Embodiments of the invention are illustrated in the drawings.

In particular, it is possible to illuminate buildings with facades consisting largely of glass, for example buildings of industrial and commercial enterprises, in a special way at night so as to produce large images with high resolution. I can. To this end, each light passage opening (eg window) in front of it is provided with an image part (partial image).
Is used as a high-resolution large image, for example, a promotional movie or a stock exchange quote is displayed on the entire surface.

FIG. 1 is a schematic diagram showing a front surface 1 of a building 2. This front surface 1 shows a plurality of light passage openings (windows) 3. Each window 3 is illuminated by a projector 5 shown in detail in FIG. As shown, the windows 3 are illuminated so that a high resolution image of the fish is produced.

FIG. 2 shows in detail how to set up this device to illuminate a window. This figure is a sectional view of the building 2 showing details of the floor and the building portion 4. The window 3 is illuminated from the opposite side of the front face 1 by a projector 5 forming a partial image.

In order to illuminate the entire surface of the window 3, it is proposed to use a membrane or rear projection screen 6 on the window glass. The material is transparent and ensures the light from the projector 5 that is captured and distributed across the entire window. Preferably, a plastic membrane or rear projection screen is used for this purpose.
