Description

DEVICE FOR IMAGE STORAGE OR CODE INFORMATION DISPLAYED ON A SCREEN DESCRIPTION OF THE INVENTION The invention relates to a device for storing image information, in particular a code displayed in a part of the monitor area, comprising a storage medium of photosensitive material, which can be secured on the surface of the monitor by means of an effective adhesion layer on the side of the monitor. A device of this kind is known from the German Patent Application P 43 12 185.3. The invention described in this patent application is based on the object of providing a device with any kind of television program that may be of more interest to the observer who is encouraged to participate and for which the television company can obtain information that It is related to the number of observers. Examples for the use of a device of the kind described are explained in the aforementioned German Patent Application. Technically, the problem occurs with this device that the information represented on the television screen is in the form of an image in a non-sharp form on the surface of the screen, due to the thickness of the glass tube, in such a way that the information represented it can not be stored in certain cases in an absolutely clear way on the photosensitive material. An object of the present invention is to design the apparatus described in German Patent Application P 43 12 185.3 for the storage of image information displayed in a part of the monitor area, in such a way that the information displayed on the screen it can be stored in the photosensitive material in the clearest way possible, or in a form which can be recognized as much as possible. According to the invention, this object is satisfied in that the photosensitive material is applied on an area carrier medium and is active on the monitor side only in specific regions separated from each other. This can be achieved particularly in that - a diaphragm or mask layer, in particular an aperture diaphragm layer, which carries approximately a focusing effect is provided on the side of the carrier medium adjacent to the monitor and becomes permeable to light in active and light-impermeable regions in the regions that are placed between the active regions and / or in which the photosensitive material is applied only to the active regions of the carrier medium.

By means of supplying the active and inactive regions according to the invention, it is ensured that the irradiated light of the monitor only activates a storage procedure in the active regions, with the corresponding regions of the photosensitive material which is delimited mutually by the regions inactive The feature of the invention, according to which the photosensitive material is applied on an area carrier medium and is active on the monitor side, includes all possible arrangements of the carrier medium and the photosensitive material in which the light that arrives from the monitor you can activate a storage process in photosensitive material. That is, the photosensitive material can be arranged on both the monitor side of the carrier medium and also, for example, when a transparent carrier medium is used - on the side of the carrier medium removed from the monitor. Since the individual active regions are divided among themselves, in each case by inactive regions and thus are separated, it is ensured that each region of the light-sensitive material destined for the storage of the information, really only receives light destined for this region, with the reception of information of light destined for the neighboring regions that are avoided by the supply of the inactive regions. In this way, it is possible to form a substantially clear image on all regions of the photosensitive material, which are in particular associated with the respective light-permeable regions of the mask or diaphragm layer. When a program is transmitted, a symbol is displayed on the screen, the geometry of which is selected in such a way that only very specific regions of the photosensitive material are exposed. By providing a specific number of active regions (for example six to twelve) the specific codes, in particular the codes that have two or three different stages of brightness, can be displayed on the screen and can be stored in the photosensitive material, with a code that corresponds respectively to a specific arrangement of bright and dark regions within the transmitted symbol. By means of intentionally disposing of bright regions on the screen only that correspond to the active regions oppositely placed from photosensitive material are exposed. By means of this method it is possible, for example during the evaluation of the storage device, to determine which type of program an observer is watching, which provides a specific symbol of the mentioned class that is associated with this program. In the manner described, a code which characterizes a program can consequently be stored in the photosensitive material and it is sufficiently possible to verify whether the storage device of the invention is secured to the screen during transmission of the program. In a possible embodiment of the device of the invention, a non-photosensitive carrier material, for example a thin sheet of metal, is used on which the photosensitive material is applied very intentionally only in those regions which are finally intended to be suitable for the storage of image information. These regions then represent the active regions of the invention, which are delimited from each other by inactive regions and to which therefore photosensitive material is not applied. In this case, it is advantageous that photosensitive material is comparatively little required, since this only applies to the active regions of the carrier medium. In this way, manufacturing costs can be reduced. When using the mask or diaphragm layer mentioned in the above, the light-permeable regions of the mask or diaphragm layer marks those active regions on the photosensitive material on which the image information can be stored. The light can therefore only reach the photosensitive material by means of the light-permeable regions and the eventually present regions of the photosensitive material, which are covered over the light impervious regions that can not be exposed. It is also of advantage when the mask or diaphragm layer is used to apply the photosensitive material very intentionally only in those regions, which are finally destined for the storage of the image information, since in this way a reduction of the costs of Manufacturing can also be achieved. The diaphragm mask or layer may consist of at least one material substantially impermeable to light, for example of paper, paperboard, cardboard or plastic, or may also be applied by means of a coating process on the carrier medium. The sharpness of the stored image can therefore be increased in that the mask or diaphragm layer is formed in such a way that a focusing effect is achieved by it. For this purpose, when using the described diaphragm mask or layer, which has a certain thickness, the light-permeable regions can each be formed, for example, by a removed cut, preferably a hole or by a slot diaphragm. In particular it is possible to use a plurality of such aperture or slot diaphragms, preferably with 3 and 500 substantially circular separate cuts which form individual aperture diaphragms which are provided. In a preferred embodiment, the separate cuts, or the active regions, are disposed substantially in a regular manner distributed around the center point of the mask or diaphragm layer. The thickness of the diaphragm layer will be selected depending on the sensitivity of the photosensitive material, on the size of the removed cuts, provided in the diaphragm layer and / or on the sharpness of an image, which will be stored and It is illustrated on the surface of a screen. In this regard, the diaphragm layer can be made thinner than the more sensitive photomaterial or the smaller separate cuts are provided in the diaphragm layer. In principle a problem that will be solved in the context of the invention, is based on the fact that the glass tube of a screen has a certain thickness, which leads to images generated on the inner side of the glass tube, which forms the image in a non-sharp way on the outer surface of the glass tube. To compensate for this lack of sharpness, the diaphragm layer is provided, for example, which carries approximately a focus of the image on the photosensitive material. In this arrangement, the focusing effect must be stronger than the thickness of the screen tube, which is why the thickness of the diaphragm layer can be made thinner so that the tubes become thinner. With a usual application the thickness of the diaphragm layer is taken into account for approximately 5 mm. In order to be able to carry out the manufacture of storage devices of the invention, as quickly and economically as possible, it is recommended that the storage device be constructed in a storage device in a substantially flat form of the different layers. In this way, for example in a simple embodiment, only one mask or diaphragm layer and one adhesion layer can be applied on a photosensitive film. By means of this flat construction, the storage device can be packaged in a space saving manner and thus can be transported and sold in a cost-favorable manner. The storage medium can be formed as a circular disk, however any of the other desired contours, for example substantially circular or also polygonal, in particular of rectangular, hexagonal or octagonal contours can be thought of. For example, it is also possible to give the storage device the form of a logo of a television company or another promotionally active form, according to a typical form for a specific business. It is advantageous from a technical manufacturing point of view, when the outer contour of the mask or diaphragm layer substantially corresponds to the outer contour of the carrier medium. For the photosensitive material use is made in particular of substances which change visibly, without the addition of a developer during the action of light, in such a way that the process of 'developing which usually could be carried out separately after the Exposure can be omitted. Photochromic substances are preferably used.

These are characterized in that they adopt a particular color by irradiation with ultraviolet light and become transparent when irradiated with visible light. Before the storage process the photochromic material is irradiated with ultraviolet light, to allow a subsequent storage of images or symbols, which reflect or transmit visible light. Between irradiation with ultraviolet light and the storage procedure, it must be ensured that the photosensitive material is not irradiated with visible light or is only irradiated with visible light for a negligible time. For this purpose, the storage material can be provided on the side remote from the adhesion layer with a light impervious layer and can be secured with the adhesion layer on a light-permeable carrier card, such as for example a cardboard Postal. The exposure time within which the storage of an image is carried out on a photochromic layer is preferably taken into account for approximately 30 minutes, however it is variable depending on the photochromic material used and on the brightness of the transmitted image. When the photosensitive layer consists of several photochromic substances, which respectively respond to visible light of different wavelength, then the color images can also be stored in the storage device of the invention. An advantage of the use of photochromic materials is based on the fact that the photosensitive material can be made reusable in a simple way, by irradiation with UV light after the exposure has been carried out. In a preferred embodiment, the carrier medium in which the photosensitive layer is introduced is provided on the far side of the monitor side with a reflective layer, in particular a bright white and / or metallic reflective layer, which reflects the rays which penetrate through the photosensitive layer, or the particular transparent carrier medium, back onto the latter. This measure leads to a more intense exposure of photosensitive material and thus shorter exposure times. An aluminum or silver layer is preferably deposited with steam on the side of the carrier medium or of the photosensitive material removed from the monitor side. The adhesion layer which is arranged in particular on the side of the mask or diaphragm layer removed from the carrier means, is preferably formed as a self-adhesive layer, which can in particular be covered by a removable protective film before the use of the device. In this way, the storage device can be sold without difficulties and in addition the observer can handle it without difficulty. The adhesion layer, however, does not need to be formed as a self-adhesive layer, for example it can also be conceived that the storage device only sticks to the screen by means of electrostatic forces. It is of advantage when a layer which absorbs visible light, in particular a black layer, is provided on the side facing the monitor. In this way to avoid disturbance reflections and exposition faults associated with it. For this purpose, the adhesion layer can, for example, also be made of a material which absorbs visible light. The storage device, for example, may be provided with an impermeable layer on the side removed from the screen. Any desired text or a desired symbol can be printed on this layer in a form visible to the observer and thus can be seen by the observer during the entire time in which the storage device is applied to this screen. In this way, the side of the storage device removed from the monitor can be used as an advertising surface. The photosensitive material can be designed for the storage of code elements of different degrees of brightness stages, in particular of two or three stages of different brilliance. In addition, it is possible to make the storage medium frequently selective, such that it only reacts for defined wavelengths of light, for example at wavelengths of light of a specific color. This has the advantage that color images can be stored. By the possibility of storing several brightness stages or a plurality of colors, the number of different codes, which can be stored can be significantly decreased.

To facilitate the placement of the storage medium on the monitor at least and in particular three or four reference marks distributed over the periphery of the carrier medium or the mask or diaphragm layer can be provided, which must be aligned with one or more masks shown on the monitor during a connection of the storage medium to the monitor. The reference mark, for example, can be formed by the outer contour line of the carrier medium, and / or of the diaphragm mask or layer, and then the symmetric line without dot, such that the storage medium can be attached to the screen with an unambiguous orientation. A further simplification of the joining procedure can be achieved when a separate central cut, in particular a separate circular cut, is provided at the center point of the diaphragm mask or layer. Since the size of the symbol to be registered with the storage medium depends on the size of the respective monitor, the size of the storage medium must be attachable, at least within certain limits to the size of the monitor. For this purpose, the laminate consisting of the diaphragm mask or layer and the photosensitive material or carrier medium, can be formed from a circular, substantially internal region and at least one ring region which concentrically surrounds the latter, with the circular region and the ring region that become separable from each other. In this form, a separate cut or active region in the ring region is associated with each separate cut or each active region in the circular region. Preferably, the associated separate cuts respectively or active regions are respectively disposed substantially on a straight line, which extends away from the center point of the diaphragm mask or layer. When a storage medium formed in this manner is used in a smaller screen, the circular region is separated from the ring region and is attached to the screen on itself, without the ring region. When a storage medium is used on a larger screen, either the complete storage medium consisting of the circular region and the ring region or only the ring region separated from the circular region is used. When a storage medium is to be used for screens of very different sizes, correspondingly more ring regions concentric with each other can be provided. When dividing the storage medium into a circular region and at least one ring region, it has the advantage that when both of the circular region and also the ring region are provided with the aforementioned reference marks, such so that the circular region alone can also be placed on the monitor without problems. At least one lens, in particular a plastic lens, which is preferably formed as the Fresnel lens, may be disposed between the screen and the storage medium or between the adhesion layer and the carrier medium. A lens of this type can be integrated without difficulty in the similar construction of a layer of the storage device of the invention. The lens, for example, can serve to further focus the symbol image in a non-sharp manner on the screen, in such a way that its image in a particularly sharp shape on the storage medium. An arrangement consisting of a plurality of lenses may, if necessary, also be used. The storage device of the invention can also be made in such a way that the developer which causes the visible stored image information to be integrated into the storage device, or in such a way that the stored image information can subsequently be revealed by a developer layer or a developer liquid, which can be carried along with the storage device. It is particularly advantageous when the storage device of the invention is mounted at the time of acquisition by the observer on a paper carrier card, cardboard, cardboard or cardboard or laminated paperboard, which in particular has the format of a postcard. In this way, the storage device can be sold in a particularly convenient manner and at the same time, the observer has a carrier card similar to a postcard available after exposure of the storage device, over which the storage device can gather. exposed and through which you can send back to the television company again. Therefore it is advantageous when the carrier card including the storage medium has a weight less than or equal to 50 g, since in this case only few postal charges are produced. Furthermore, it is advantageous when the storage device is releasably secured on the carrier card similar to a postal card by means of its adhesion layer. In this case, the supply of a protective film covering the adhesion layer can be omitted. The adhesion layer can also be reused again after exposure of the storage device to secure the storage medium on the carrier card similar to a postcard. It is possible to directly store more than one storage device on the carrier card. Preferably manipulation depressions are provided in the carrier card to simplify removal of the storage means. In the context of the invention, a method for the technical transmission of a code was developed, which can be displayed on a part of the area of the television screen, which consists of various code elements of different stages or colors of brightness and which can be stored in an optical storage medium of the described type attached to the television screen. In order to provide the possibility of storing codes, shown on television screens of different sizes in the unit size storage means, the code has according to the invention, at least one substantially symmetric point shape. Preferably, the code has a circular shape, with the code that is transmitted in code elements, which are substantially in the form of a circle sector and joined together. 38 In addition to the advantage when specific code elements of a code can be transmitted in one time in the form of one after another within a television program, since the television observer then never sees the complete code on the screen, which leads to increased security against counterfeiting. In addition, it is of advantage when the code is not necessarily transmitted with a specific television program but on the contrary, for example it is selectively mixed in the teletext means, such that only those television watchers cause a code to be displayed on the television. which uses the storage device of the invention. Other preferred embodiments of the method for transmitting the code of the invention are described in conjunction with Figure 4. In addition, other advantageous embodiments of the invention will be set forth in the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS A preferred embodiment of the invention will be described in the following with reference to the Figures in which are shown: Figure 1, a screen with a storage device according to the invention, Figure 2, a plan view schematic of a carrier card with storage devices according to the invention, Figure 3, a very enlarged section AA through the storage device according to the invention and according to Figure 2, and Figure 4, the illustration of a code transmitted with the method of the invention. Figure 1 shows a highly schematic form of the front view of a monitor or a television screen 1. In the upper left corner of the screen, a storage device 2 similar to a disk according to the invention, is directly joined to the screen and covers a part of the television image area, which can be displayed on the screen. Figure 2 shows a carrier card 3 for six storage devices 2 according to the invention. In the same way, more or less storage devices can also be arranged on a carrier card. The carrier card 3, for example, can be manufactured from cartonboard and have the format of a postal card. In this way, the storage devices 2 of the invention can be sold in a particularly advantageous manner, since the carrier card 3 can be used, on the one hand, since the packaging for the sale of the storage devices 2 and on the other hand side, also for the return of the storage devices 2 exposed. The storage devices 2, which preferably have a thickness of approximately 5 mm, in the same way as the carrier card 3 are inserted in the separate sections of the carrier card 3, which are coupled to the shape of the devices storage 2. An undesirable separation of the storage devices 2 from the carrier card 3 for example is prevented by the frictional coupling between the edge region 4 of the storage devices 2 and the respective separate cut. The storage devices 2, however, can also be secured by means of their adhesion layer to the carrier card 3. To facilitate the removal of the storage devices 2 from the carrier card 3, the holding or manipulation depressions 5 are provided. on the carrier card. The storage devices 2 consist of a substantially circular, inner region 6 and a ring region 7, which concentrically surrounds the latter with the circular region 6 and the ring region 7, preferably only being connected together by friction forces , in such a way that they can be separated from each other as desired. The ring region 7 has eight separate cuts 8 through which light passes over the photosensitive material contained in the storage devices 2. The eight separate cuts 8 are evenly distributed around the periphery of the ring region 7. separate cut 9 in the circular region is associated with each separate cut 8 of the ring region 7. In this arrangement, the respectively associated separate cuts 8, 9 are each arranged substantially in a straight line extending away from the central point 10 of the storage device 2. Four reference marks 11 which are evenly distributed over the periphery of the storage device 2 , is provided in the ring region 7 and serves for placement on the screen 1. Three of these reference marks 11 are formed as triangular notches and one of these reference marks 11 is formed as an outward projection similar to a formation triangular. The circular ring region 7 is provided with corresponding reference marks 12.

At the central point 10 of the storage devices 2, a separate, centered, circular cut 13 is provided, which can additionally serve for placement. To prevent the exposure process from being carried by the monitor 1 from being simulated directly with an intentionally used light source, or to make this more difficult, at least a separate cut 24, 25 which provides security against forgery, can be placed in the storage device 2 or in the diaphragm mask or layer in such a way that the active region formed by this separate cut 24, 25 provides security against counterfeiting which receives light from at least two of the code elements, which can be displayed on the monitor. If one of these two code elements is dark and the other is light, then a medium brightness value is placed between the exposure by a dark code element and the exposure by a light code element, will be stored on the photosensitive region associated with the separate cut 24, 25 providing security against counterfeiting. The simulation of this average value is significantly more difficult to take away since the simulation of only one stage of dark exposure and one stage of brilliant exposure, so that security against counterfeiting is increased as a consequence. In one embodiment of the invention, six separate cuts 24 providing security against counterfeiting, are provided in the ring region 7 and six separate cuts 25 providing security against counterfeiting are provided in the circular region 6. As already mentioned, the storage devices 2 can be disposed releasably on specific regions of the carrier card 3 before use. To effect the exposure, the storage devices 2 are removed from the carrier card 3. After their exposure, the storage devices 2 can be reinserted into the carrier card 3 and sent together with the carrier card 3 as a postcard to the television company. The address of the television company is preferably printed on the reverse side not illustrated of the carrier card 3. The carrier card 3 can also be provided with separate pass-through cuts, in which the storage devices can be inserted after the exposure or on which the storage devices can be inserted after their exposure, with the side of the storage devices provided with the adhesion layer, then be considered through the separate cuts on the back side of the carrier card. This facilitates the evaluation of the exposed storage devices, since for example, they can be investigated by an image processing system without having to be removed from the carrier card. To avoid, with a carrier card of this type, additional exposure of the storage devices after they have been applied to the carrier card, the latter is in this case provided on the back side with a cover element impervious to light , for example a thin sheet of removable metal or cartonboard material, which can be folded back. A thin sheet of transparent metal can preferably be provided between the light-impermeable cover material and the glue on the storage devices, at least in the regions of the separated cuts. In addition, the carrier card can also be provided on its front side, over which the storage devices are glued, with at least one other layer which, for example, protect the gluing on the storage devices against damage or cover over them . A large number of other modes of the carrier card are conceivable, for which it is that the storage devices exposed to no other incident light after the exposure has been carried out with a simple reading of the image information stored in the glue on the storage devices is never possible. Figure 3 shows a very enlarged section A-A through the ring region 7 of the storage device 2 according to Figure 2 before its application to the screen. The storage device 2 is constructed in the form of a layer, with the adhesion layer 14 light-permeable or transparent activates the side of the screen, which is covered before using the storage device 2, by a protective film 15 which can be pulled by the user of the storage device of the adhesion layer 14 in the direction of the arrow. The storage device 12 can then be secured to a screen with the adhesion layer 14, which is exposed after removal of the protective film 15.

The adhesion layer 14 is followed by a diaphragm layer 16, which is provided with separate through cuts 8 in the same shape as the adhesion layer 14. The diaphragm layer 16 is made of light-impermeable material, such that the light can only pass through the diaphragm layer 16 in the region of the separate cut 8. When the diaphragm layer 16 or the separate cuts 8 become adequately thick, then a focusing effect operates in accordance with The opening diaphragm principle can be achieved. Therefore, the thickness of the diaphragm layer 16 or the separate cuts 8 should be selected depending on the sensitivity of the photosensitive material and on the thickness of the glass tube of the screen. In this way, the very sharp image of the image displayed on a screen can be achieved on the photosensitive layer 17, which is connected to the diaphragm layer 16 on its remote side of the adhesion layer 14. The photosensitive layer 10 is followed on the remote side of the diaphragm layer 16 by a suitable reflective layer 18 for reflection of the light irradiated by the monitor. This reflective layer can, in particular, be of a metallic design that reflects the light irradiated by the monitor and which passes through the photosensitive material 16 back onto the photosensitive material 17. All layers are preferably made of flexible material, which in particular it facilitates the release or removal of the storage device from a screen. Figure 4 shows a code 19 which can be transmitted with the method of the invention and which is suitable for the exposure of the storage device 2 according to Figures 2 and 3. The code 19 is constructed in a pointed form symmetric in relation to its central point and has a substantially circular shape. The code 19 is divided into eight code elements 20, 21, which are in the form of a sector of a circle. In the example shown in Figure 4, the specific code elements 20 are shown with light while the remaining code elements are shown dark. Through different arrangements of the light and dark regions and also through a variation of the relationship between the numbers of light and dark regions a total of 256 different codes can be transmitted or represented, when eight code elements are used 20, 21 in the form of a sector of a circle. The storage device 2 is linked respectively to the code 19 shown on the screen 1, such that in each case a separate cut 8, 9 is located on each code element 20, 21 by which the information (light or dark) ) contained in the code element 20, 21 is transmitted on the photosensitive material 17 of the storage device 2. Since the code elements 20, 21 have the shape of a sector of a circle, a correct exposure of the storage devices 2 always ensures, when the separate cuts 8, 9 are located on the region similar to an associated circular sector, respectively of the code 19. A variable arrangement of the separate cuts 8, 9 in the entire region of a code element 20, 21 which has the shape of a sector of a circle in this way is possible, at least when the area extension of the separated cuts 8, 9 is substantially smaller than the extension of area of the code elements 20, 21. In this way it is ensured that for the storage of the codes 19 represented in different sizes in the television screens 1 and which then to itself have consequently variable sizes, a constant unit size it can be stored in a storage device 2. In this way, the unit storage devices 2 can be used within a certain range for different sizes of screens. If this range is exceeded then the storage devices 2 can be divided, as explained for the example in relation to Figure 2, in two regions 6, 7 of different size. A region 22 similar to a point is transmitted at the central point of the code 19 on which the central separated cut 13 of Figure 2 can, for example, be placed and which can change its color during the exposure time. A color change can therefore be carried out, for example after the exposure time has completely ended. At least at the beginning of the transmission of the regions 23 similar to an arrow of the code 19, they can be transmitted distributed over their periphery, for example in three positions. These regions 23 similar to an arrow serve for the placement of the storage device on the screen 1. The marks 11, 12 similar to a notch according to Figure 2 are in particular to be aligned with the regions 23 similar to an arrow.

The method of the invention is not restricted to the mode shown in Figure 4 for the transmission of a code 19. More or fewer code elements can also be contained directly in a code or a plurality of stages or brightness colors can be transmitted. per code element. In particular, when transmitting a code with three stages of "bright", "medium" and "dark" brightness, at least one specific code element of the "middle" stage can be transmitted in that it is transmitted in approximately half of the Total exposure time as a "bright" stage and during the rest of the exposure time as a "dark" stage. In this way the security against counterfeiting can be increased, because the television observer by considering the code which is shown once, can not judge which code element finally calls the "average" value in the device. storage.
