DESCRIPTION:
BRIEF SUMMARY
The present invention concerns a method for creating and storing a design adapted, when placed in the light beam of a projector, to produce an illuminated area creating a decorative lighting effect on a stage, for example.
Opaque plates incorporating transparent areas allowing a light beam to pass only through these areas are usually employed. In the theatre the decorative lighting effect is obtained on the stage according to the shape and the illumination of these transparent areas which are of predefined shape.
The present invention enables the user to produce for himself plates with designs required for a show in relation to what is happening on stage.
The method for creating and storing a theatrical design adapted to produce scenic effects consists in persons thereon, adapted to produce first scenic effects, producing scenic effects complementary and/or supplementary to the image of the stage, scenic effects and comprising data respective to the stored drawn image.
However these drawings are obtained, their contours are transferred to the glass plate to be projected and initially covered with an opaque coating adapted to be cut away to expose areas through which the light is to pass.
According to the invention there is also provided apparatus for creating and storing a theatrical design adapted to produce scenic effects comprising: props and persons thereon adapted to produce first scenic effects, producing on the display screen scenic effects complementary and/or supplementary to the image of the stage, supplementary scenic effects on the basis of data respective to the stored drawn image.
Preferably: (18) constituting image capture apparatus, third system (17), one computer (13-14) associated with the computer-assisted drawing device.
Advantageously: cutting out an opaque material coating film on glass and a station for exposing the cut out areas.
The scope and the benefit of the invention will be better understood from the following description with reference to the appended drawings in which: with the invention used to store a required scenic design; project said scenic designs producing the required scenic effects; FIG. 1; and production system.
The components of apparatus in accordance with the invention will emerge from the following description of its use to store a required scenic design.
A projector 12 illuminates a stage 11 complete with scenery and props and on which persons may be present, each of these entities being denoted by the same reference number 10.
The apparatus in accordance with the invention is adapted to form a complete image of the entire stage on a frosted glass plate 4 through the lens 1 of the first optical system. The image is focused by a known type control device 9 and by a total internal reflection mirror 2 preferably disposed at 45.degree., said mirror being hinged at 25 and controlled to enable use of the apparatus for projection as will be explained hereinafter.
The image formed at 4 is "read" by a video camera 6 and represents exactly what will be projected by the apparatus 18 onto the stage 11 and objects and persons 10 thereon.
This image is fed in a way that is known in itself into a first computer 13 or onto a video screen of the storage system to be stored digitally and visually on the screen 8 whilst being inventoried (again in a manner that is known in itself) using the keyboard 15.
Note that the image appearing on the screen 8 is a faithful representation of the stage 11 and objects, props and persons thereon as they would appear to an observer located at the window 3 of the projection apparatus (FIG. 2). This image is introduced into a computer 14 running conventional computer-aided drafting software with its graphical input keyboard which draws lines representing complementary or supplementary effects which may be visible on the screen. By superimposing the image from the camera 6 and the image produced by the computer-aided drafting system and transmitted by the computer 14 it is possible to preview the effect that would be achieved by projecting the im
