Definitions
- the invention relates to a method and a device for lighting objects such as monuments (churches, castles, constructions, etc.), scenes or natural sites for example.
- monuments churches, castles, constructions, etc.
- the invention aims to meet this need.
- the projection of the processed image on the building makes it possible to illuminate it while decorating it, for example by coloring colonnades in blue, statues in white for the characters and in color for the clothing or accessories, frames in red, windows in yellow, etc. with such precision that, for the viewer, the impression is identical to that which a painting of these parts of the building would produce.
- this method consists in taking at least one photographic or cinematographic image of the object, in digitizing this image, in processing it digitally, in printing a photographic or cinematographic film with the processed image, develop this film to obtain the processed image on transparent film and project it onto the object.
- this method consists in taking at least one video image of the object, in digitizing it, in processing it digitally and in projecting the processed image onto the object by means of a video projector or a laser beam lighting device.
- the invention also provides a device for lighting an object, in particular by carrying out the method described in the above, this device being characterized in that it comprises means for taking an image of the object , means for processing this image and means for projecting the processed image onto the object.
- the image taking means can be of the video output type, such as for example a CCD camera, the projection means then being of the video input type, such as for example a video projector or a lighting device. laser.
- the image taking means may be a camera or cinematographic, the processing means then comprising means for digitizing the image, digital processing of this image and exposure of a photographic or cinematographic film, the projection means then consisting of one or more optical projectors classics.
- FIG. 1 schematically shows the taking of images and the projection of images on an object such as a building
- FIG. 2 is a flow diagram of the main steps of the method according to the invention.
- FIG. 1 There is shown schematically in FIG. 1 a building 10 which it is desired to illuminate in a particular way on the occasion of any event, for example a commemoration, a party, a sound and light festival, etc.
- the invention provides for taking at least one image of a part of the building to be lit, using a photographic camera 12 or a video camera of the CCD type for example, placed in relation to the building 10 at a location P such that the image of the building 10 captured by the objective 14 of the camera or of the camera 12 occupies as much as possible of the sensitive surface on which this image is formed (a photographic film or a CCD sensor array).
- this projector can be a conventional projector (of slides), or a video projector or a laser lighting device depending on the type of image to be projected.
- step 18 include a first step 18 of taking an image of the building 10, followed by a step 20 of development when the image has been taken by means of a camera of a conventional type which prints a black and white or color photographic film, after which the photographic image is digitized as indicated in 22 by means of a scanning reader ("scanner") and loaded into memory in the information processing system 16 such as a microcomputer or a microcomputer equipped with appropriate graphics processing software.
- a scanning reader scanner
- the image of the building 10 is taken by means of a CCD video camera or the like, the image obtained is digitized and then loaded into the information processing system for processing therein as desired, as indicated in 24 in figure 2.
- the processing carried out on the image of the building 10 may include, for example, chromatic balancing, modifications of the color and the luminance of certain parts or of certain architectural patterns of the image, inclusions of picture elements, blurring effects, retouching, etc.
- window frames can be colored in yellow, columns in blue, statues in white, balconies in red, green roofs, etc. We can also add moiré, marbled or similar effects on certain parts of the image.
- image processing could also be done by hand (painting, retouching, etc.)
- the image resulting from the processing 16 can be applied, by means of an appropriate interface, to the input of a video projector or of a laser beam lighting device as indicated in 28, to be projected onto the building. 10 from the aforementioned location P, or else if a conventional projector of the slide projector type is used, the information processing system can be connected to a photographic imager making it possible to print a photographic film with the image treated as indicated in 30, this film then being developed to provide a positive image on transparent film which will then be projected on the building 10 from location P, preferably by using the objective 14 which was used for shooting or an identical goal.
- the surface to be lit of an object when the surface to be lit of an object is large, it is divided into adjacent zones of determined maximum surface (for example of approximately 400 m) and an image is projected onto each zone of this surface, in using as many projectors as there are areas to be lit, which makes it possible to obtain both good color rendering, high brightness and high contrast.
- the distance between the projectors and the object to be lit and the dimensions of the aforementioned areas of the surface of the object are generally compromises between the characteristics of the optics used, the terrain and the projection lamps. Typically, the distance can be a few tens of meters, for example 30-40 m.
- this decorative lighting of the building 10 can be variable over time, by modification of the colors, their saturation, the light intensity, etc.
- a cinema projector to project a cinematographic film treated as mentioned above, for example impressed by processed images of the object and / or by computer-generated images, and then developed.
- the initial images can be photographic, cinematographic or video images.
- the projection of an image or of the processed images reproduced on film can be carried out by means of a commercial projector using a high-power lamp (from a few hundred to several thousand watts).
- the invention allows polychromatic decorative lighting of buildings, constructions, monuments, sculptures, scenes, etc. or of natural elements such as rocks, cliffs, etc., as well as the reconstruction of paintings, frescoes or animated scenes on ruins, walls of buildings, rocks, etc ...
