FR2489009A1 - Multiple image photographic display - has flat surface photogravure using parallel strips of image with spaces between - Google Patents

Abstract

The display makes several images or photographs from a single image. This image, over all its flat surfaces, is divided by straight lines into parallel strips. This solitting up can have 2 to 20 strips per mm. The more the lines, the greater the resulting detail. The final result is one made of strios and parallel spaces. The space width is always equal to or greater than that of the strip. This allows hollows to be formed by photogravure on a defined support and two reflecting surfaces for light, using acid etching. The strips can be selectively replaced by those from another photograph or image.

Description

 Several existing devices show images that undergo changes loraquSon changes the angle of view.The images exist under the name of "image with changing views" these images can give the illusion of relief, displacement.

All these devices have in common the same process of optical deflection of the device. The whole of this device includes, 1st a printed support of one or more images, decomposed and
located. 2e a transparent layer having a lenticular optical network in relief.The transparent layer is applied, glued on the printed image.Oe lenticular network is in agreement with the printed fractional image network, the assembly thus forms a restituting support of images that can not work one without the other printed image + transparent lenticular support.

 Changing images exist under the known name of "Hologram" is a sensitive transparent multilayer photo, containing microscopic visual information corresponding to several images photographed from different angles.

 Images with changing effects can be made directly on a light reflecting medium, these effects are obtained mechanically, polishing, sanding, milling etc ... or manually with different tools, scraper, chisel, sandpaper etc ... There is also an embossing technique which makes it possible manually to execute on a malleable aluminum sheet, drawings showing play of lights. The drawings are obtained by rubbing the front of a transparent plastic sheet, having on the backside a network of lines that are invisible to the eye of an observer placed under normal viewing conditions. The drawings etched on the aluminum sheet can be molded and reproduced, the reproduction being reusable as the main support for the execution of a second one. drawing by the same technique of embossing.The realization of this kind of drawing is always done by embossing or pressing, a first support grav on a second support more malleable than the first.

The use of the word "waffle" will be used to designate and mention this particular action of reproduction of etchings on aluminum foil.
With this method we can obtain some effects of lights and movements, on a reflective or transparent support with rotational movement airplane seat, bottom of saucepans movement of a mechanism or machine walking movement of a human being or The animation is good when it is a question of visually restoring a single embossed image on the same corresponding surface. In the same format it can be carried several images having contours. and modified dimensions, each image being embossed in a different sense, an observer creates an illusion of motions, appearance and disappearance of an image.

The quality and the rendering of the movements are better when the embossed engraving gratings receive light rays in an established order.

 This embossing process gives mediocre effects when it comes to restoring the simultaneous appearance of images, when they are placed on the same plane with identical dimensions.

 This method does not allow the faithful transformation of a given image, black and white or in color, into a reflecting image or deviating light. The techniques employed do not allow the selectivity of differently oriented local zones that can be used to render several images of same dimension on the same surface having good light definitions.The realization of a surface with changing images with conventional embossing techniques, results in a poor definition of each image and the total set of the reflective surface, it creates overlaps, crosses.

These superimpositions which have the effect of dispersing the light rays where exactly these same rays should be reflected in a single direction in order to restore a maximum fraction of an image, all of these fractions representing the image.

 The aim of the invention is not only to eliminate these drawbacks, but also to make it possible to produce a selective device for orienting light-deviating zones, the field of application of which is much larger than that of the drawings made on aluminum foil having networks of engravings invisible to the eye of an observer placed under normal observation conditions.

 The invention allows the realization of movements of lights or shadows on different reflective or non-transparent or opaque surfaces. # The concerns the establishment of éléméntssde plans, indications, mentions, a process of fabrication resulting in the creation of a surface deviating light according to a well-defined order, a law.This surface is composed of one or more images.Each image has been divided entirely of a regular sequence of points of various shapes. or delineates (Fig.6 in X, Y having been advised in a given direction, in a series of parallel straight lines forming furrows composed of lines and spacings of determinate dimensions.

 According to the use of application of the invention, fafr # cation of postcards, posters, lines and spacings will have widths (Fig.5 in C1, C2, and e) of the order of mmwdu I / IO of millimeter or I / 30 da mm, the dimentions of the points or lines of the order of some ##, mm or I / IO of millimeter.For the surfaces of bigger dimensions, decoration of architecture, the gaps may be of greater definition, mm, cm, several cm.A surface thus formed, may be made reflective or deflect the light by several methods. The lines and spacings can be made in relief, recessed, constituting walls that can reflect or deflect the light or create a shadow. Each relief or hollow being oriented in the corresponding directions, with lines and spacings of various orientation.

 This surface being a negative or positive photographic document, this film can be used directly for the production of a relief surface that can reflect, or deflect the light by photoetching of this surface. This surface may be formed of various materials.

This engraved surface can be used as a cliché to reproduce by various embossing techniques, the engraved images, on a more malleable support than the snapshot. This engraved surface can be reproduced by electroplating, by molding. This reproduction, can ## be used like cliché or matrix to reproduce its own images engraved on another more malleable support. This relief surface can be the representation of an image having lost these colors. The colors being rendered by projection of light of colors different, each color being restored on specific areas for this purpose, corresponding to the lost colors. The whole of the color image thus formed can be seen by a single observerOverall the same surface can be fractionated regularly in 2 , in 3 zones, of various shapes, of points or lines, having positions and regular surfaces determined, avoiding the creation of interstices (Fig.6 a and b) .This constituted surface can be used as
TV screen, cinema, slide projection etc ... Its characteristic is to be able to restore in different orientations visible under observation angles, corresponding to the angles of projection, defection and orientation of the grooves.

 The lines and points arranged next to each other, having definite defection orientations, corresponding to the divisions of the surface deviating the light # Ai-nsi if one wants to divide the screen so as to obtain 2 surfaces deviating the light in 2 different directions, the deflection points or lines constituting this surface will have a deflection power corresponding to 2 different orientations (FIG. 6 a and b), a point or a deflection line in a given direction will be set apart from a second point or line of deflection in a different direction than the first and so on alternately and regularly over the entire surface defined on the screen. For the screen to reflect 3 images projected in 3 different directions we will proceed a way identical to that described for the restitution of 2 images, but by dividing the screen into 3 zones of points or deflector lines oriented in different directions, the points and the different deflexiorl lines are always placed next to each other alternately # The shape and the surface of the points and lines can be variablea # The luminous power of restitution of an image corresponds to the division of the 6oran.The screen being divided into 2 different orientation zones, the image thus projected in one of the deflection zones will be restored to 5Q <0, the remaining 5 # of surface being used for the projection of a second identical or different image. having 3 zones of different deflection orientations, the image restored to the observer will correspond to one of the 3 zones of deflections. The image thus restored is divided to I / 3.

 A panel being split into 4 different deflection zones, the projected image having its area divided by 4 and so on.

As many times the screen will be divided into different deflection zones, in as many times the visual rendering power of an image will be divided.

This technique of division is identical and gives the same powers of restitution in percentage of definition, that when the surface is itself-support image. One can decrease or increase the surface of a zone with respect to the others in order to degage or to diminish its reflective power.

 The constituent elements points, lines and deflection spacings may be visible or invisible to the eye of an observer. This surface may be of varied size, of the order of a microfilm, a postcard, an advertising poster, an architectural surface, "Solar Panel".

 The implementation of the invention is possible thanks to a process also forming the invention which determines the orientation elements, the direction of deflection in the form of planes, frames, grids drawings, positive or negative films obtained directly. from an original image avoiding the technique of "embossing" to form a surface having the power to create movements of lights, movements of changing images. To transform a normal ordinary image or photography into a deflector image.

The light is deflected by encountering obstacles placed on its possessions by reflection or by transparency. The invention determines the positioning, the senses, the well-defined orientations to give to these obstacles so as to create selected sets of lights, to perform srfaces with n changing images H clearly defined light deflection patterns. The positioning, the direction and the orientations will be in the form of visual indications (as shown by the
Fig.I, 2,3,4,5,6,) can be executed on paper in white or black print, in color, on transparent or opaque support.The indications may be in the form of lines, arrows direction, of parallel lines of orientation angle with respect to a given point, the assembly constituting the splitting of a
An image on the angular orientation of elements that can cost an image or a movement of light. The interpretation, the reading of such a document giving rise easily to the creation of a well defined animated surface.

 Figures 1,2,3,4,5,6 give representation in black and white, indications that can be used for the realization of such a surface.

The establishment of these sets of lights can be obtained on different supports in relief or flat "polarization" on horizontal or vertical surface.

 The divisions mentioned in the various figures 1,2,3,4,6 may correspond to etched gratings of parallel straight lines, they may correspond to polarization angle indications Jzaglcr, they may correspond to the establishment of surfaces in relief reflective or not, in this case, the divisions indioations of the plane may correspond to the positioning of elements relative to the other recesses or relief eto ... The assembly undergoing the angular offset corresponding to the indications.

The assembly giving rise to the establishment of a surface having well defined deflection characters.

 Figures 1,2> 3 illustrate the embodiment of orien taticn surface giving rise to well defined sets of lights.The surface can be Astre for example a light reflecting aluminum ttle, the given orientations corresponding to parallel straight lines The sources of light may be the sun, the moon or electric lights.

In FIGS. 1 and 2, the etched support being placed horizontally, on one side of this support, a single source of illumination, in (F), on the other side an observer in (a), on the support, a zone illuminated in (e and FIG 1) / Creation of a single and unique diffraction movement moving in the same direction of march as the observer.A rectangular band is divided into 9 boxes, each box being divided into a series of lines and spacings, of determined orientation
The orientations will undergo an angle shift in the same direction of travel, that of clockwise, the set of shifts alternately effected from 0O to 1800, from box 1 to box 9.

The observer A placed in (a) sees the zone (e) corresponding to his diffraction angle with respect to the light, that is to say the box n050
The observer A moving towards Y the observed diffraction zone (e) will pass alternatively on the squares 6,7,8, 8 being the predominant zone of illumination for the observer Ai. In the same way the observer A going towards x will see the light moving in the maem sense, of the box n05, it will pass in 4 then in 3.2, the box n02 being the predominant zone of lighting for the placed observer in A2.

FIG. 2 / Creation of a single movement of light or diffraction pointing in the opposite direction of the walk of an observer.The observer
A goes to Y, the movement of light (e) going to X, the zone Z> diffracting the light on AI.From the observer A moving towards Xlthe diffractions will be done alternately on the zones 6,7,8, box 8 restoring the light to the observer placed in A2.

 FIG. 3 / Creation of 2 diffraction zones with inverse movement.

A band is divided into 17 boxes from 1 to 9, offset angle from 0 to 1800 against the direction of travel of a needle. shows, creating a 1st light zone in (eI) .From 9 to I7, shift from 0 to 1800 in the running direction of a watch hand, creating a second light zone in (e2).

The observer A perceives the 2 lights corresponding to the 2 diffraction zones, the first zone (e1) on the box n05,2th zone (e2) on the space n I3. The observer Ase directs towards Y, the second zone (e2) alternatively passes from I3 to 14,15,16, the first zone (el) passes over 4,3,2, the observer A1 distinguishes boxes 2 and 16.The light zones (e1 and e2) are separated by one of the other. The observer A moves towards X, the zone 1 of the box n05 passes on 6,7,8, the zone e2 of the box n013 passes on I2, II, IO.The observer A2 distinguishes the boxes 8 and IO.

The zones of light (e1 and e2) -se are brought closer to each other.

the whole of this network of offset of opposite angles gives rise to the creation of a very fast movement of 2 lights coming up or moving away according to the direction of march of the observer. As we note the least error in the Establishing the direction of orientation of the diffraction zones will result in a loss of light, a poor restitution of the image thus established, it will thus form a local scrambling of the image.The invention does not use the technique of "embossing ", but using techniques allowing a perfect control in locating points or lines and spacings, used for different printing processes," color selection "photography.

A photograph, an image having several shades of colors, have 1/2 tints. To reproduce this document by other processes than that of photography or photoopia, we establish a "typography" (the term typons in this This patent can be processed in several ways, in the form of imitation or negatives. Each treatment aims at decomposing the document into a multitude of points, of crossed lines having surfaces of different sizes corresponding to differences in color intensities.These conventional techniques of color selection, imitation or raster used for printing can be used only to reproduce the original image by different means of printing These same classic types, in imitation or raster, used for printing can not be used to reproduce an image for the purpose of transforming it into an image having the characteristics is to intercept the light correctly, to reflect it or to deviate it according to an established law. To arrive at this result we will
take a raster of parallel straight lines with the same definition of
finesse corresponding to the size of the image to be reproduced.
say more will be the parallel straight lines, more name
Many will be the details returned from the image at the photographic level
we will use a frame with 2 to 20 dashes for the establishment.

FIG.4 / To transform an image having 3 colors in applat,
we will establish 3 types corresponding to the 3 colors. Each color
being woven in a different sense.The direction of orientation will correspond

In this case, in FIG. 4, the red in (R) being framed at 430
compared to yellow (J) or blue (3). The yellow (J) being screened at 900
compared to blue.We thus get 3 types each having a
orientation of different determined lines, corresponding to the 3
colors (R, B, J). We will overlay the 3 types by positioning them
and we will make a single piece of lassensless 3 zones
being well separated from one another.This document
allows the execution of a photoengraving, the photoengraving transforming
frames (continuation of lines and d> spacings) in relief, the reliefs thus
determined will have the power to reflect light.In Fig.4
each color transformed into an engraved #one, whose features and spacings

zone by changing the colors of the corresponding lights.
a surface rendering 3 different images, occupying the same surface,
we will proceed in the same way as for the image having colors in flat. That is to say that we will have 3 types of lines of parallel lines.

Each artwork will represent an image with a different orientation
compared to the other 2 and this still on 900.The superposition of
3 screened figures in 3 different orientations of parallel straight lines will result in the establishment of a single final artwork used for the realization of a photogravure, this photogravure will give poor results of restitution of light. The engraved lines being entangled creating many interstices.The surface engraved with a scrambled luminous definition.To remedy these overlaps and these superimpositions, 8 these crossings, we will retrace each already framed artwork, with a dot pattern of various shapes, or lines (Fig.6 in X and Y). Each artwork will represent the 1/3 of the image support surface, that is to say that we will erase by 2/3 each artwork, therefore each image or color. The erasure will be done by superposition. of the first artwork on a second artwork used as cache.The division of the artwork will be done in a regular way with a cache frame, (Fig.6 in X and Y) of regular divisions- will then get 3 types representing more than 1 / 3 image cha one, which can be superimposed, without crossing lines, overlap or overlap, for the creation of a single artwork.To establish a surface with the characteristics to reflect, to deflect the light or to create shadows this surface being able to reproduce I, 2,3,4,5 images in different observation orientations, this surface being able to restore an image having 1,2,3,4,5 1/2 colors, we will divide each image or color (image and color having already been framed in parallel straight lines in a given direction3 into 1,2,3,4,5 zones of points or lines of regular layouts.

Each image or color having at its disposal and being able to occupy 1, 1/2, 1/3 1/4, 1/5 of the total surface. This division is done either with regular screened characters serving as cache, (Fig.6 in X and Y) this division can be carried out on a plane, or directly by different processes during the production of the image-forming surface or image-deflecting surface. This area is divided into as many once there will be images or colors to be replaced.An image or color may occupy a surface more or less important compared to another.Ces divisions can be established directly at the level of the shooting, a photographic camera or film, according to different methods. A single camera having several different angle-of-sighting objectives may, with a grid and cover system, obtain a photo or film which can be used for visual reproduction. in surface deflector reli # f, dtu n # or more images according to the invention.

There may be other ways to use typography
screened to obtain a photoengraving deflector of images or colors,
whose purpose is to divide an image into a multitude of features,
spacing, different orientations or straw all consistent
in the restitution of an image or color, by deflection of light
on the spacings engraved between the lines. We can draw thus from a succession of lines and spacings of different orientations
or not, one or more images or an image having multiple colors.

The entire pattern of lines and spacing may be subject to
photographic reduction, to obtain features and spacings
tighter for better optical definition of the image or
color, once photographed. Photogravure made, directly
with the type (s), or positive or negative films determined by
the invention itself becomes the deflector relief surface, which can

These are the lines and spacings of the parallel lines (Fig.5
o, d # e) which once etched by the acid, constitute surfaces in
relief with walls (Fig.5 B and A) that can reflect
light or deflect it in one direction, in a certain direction
by: 1st, the inclination of the engraved walls, (Fig.5 FI, G2 and HI, J2)
2nd, the orientation direction of the parallel lines (Fig.5 FG and HI).

 Images, fractions of images, various movements of light effects and shadows may have been photoengraved with good definitions.These deflector photogravures thus formed can be reproduced by different existing techniques, they can be used as clichés by embossing, they can be reproduced on a flexible or rigid transparent plastic sheet which can itself become a reproduction snapshot. The snapshot thus formed allows the realization of a new game similar to the transfer of images or of decals, "relief", with a great advantage, that of being able to preserve the drawings, the fractions of drawings or the letters, constituted and treated, transformed by the invention. These engravings thus constituted will be reproduced on a support of malleable aluminum, exercising with the help of various instruments: spatulas, burnishers, local pressure on the smooth side (front side) of the foil This transparent technique will be used to transpose the engravings, on the side (verso) in relief, on the malleable aluminum sheet.Lton can thus reproduce and draw characters and and various illustrations, as well as the reproduction of certain effects of particular light. interesting.
