Definitions
- the invention relates to a device for storing image information displayed on a partial area of a monitor, in particular a television screen, with a storage medium which can be fastened to the monitor surface by means of an adhesive layer effective on the monitor side.
- Such a device is known from document US-A-4 613 904.
- a device is disclosed there by means of which optical signals can be detected via a photocell and then stored as electrical signals. This device can be attached to a monitor using two adhesive strips.
- a disadvantage of these known methods is that the attraction for the viewer is often not great enough due to the constantly recurring same broadcasting scheme, and that viewer puzzles and viewer surveys cannot be integrated into every type of television program.
- the invention has for its object to provide a simple and economically producible device with which any type of program can be made more interesting, with which the viewer is encouraged to participate and through which the television stations can receive information about the broadcast participation.
- the storage medium is made of photosensitive material in a device of the type mentioned.
- Such a device can be used as follows:
- the television transmitter emits a symbol, in particular on a black background, at a specific time or permanently at a defined point on the screen.
- the viewer attaches the device according to the invention to the screen by means of the adhesive layer in such a way that the symbol shown on the screen is covered.
- the symbol displayed on the screen thereby exposes the photosensitive material integrated in the device according to the invention, whereby the image information of the symbol shown is stored in the device according to the invention.
- the storage device according to the invention can then be detached from the television screen and sent, for example, to the television transmitter with the stored image information.
- the storage device In order to be able to manufacture the storage device according to the invention as quickly and economically as possible, it is advisable to build the storage device essentially flat from different layers. For example, in a simple embodiment only an adhesive layer is applied to a photosensitive film. Due to this flat construction, the storage device can also be packed in a space-saving manner and thus transported and sold in a cost-effective manner.
- the storage medium can be designed as a particularly flexible circular disk, but any number of other contours can also be envisaged. For example, it is possible to give the storage device the shape of a transmitter logo.
- Photochromic substances are preferably used for the photosensitive material. Photochromic substances are characterized by the fact that they assume a certain color when irradiated with UV light and become transparent when irradiated with visible light.
- the photochromic material Before the storage process, the photochromic material is irradiated with UV light in order to enable subsequent storage of images or symbols that reflect or emit visible light. Between the irradiation with UV light and the storage process, care must be taken that the photosensitive material is not irradiated with visible light or only for a negligible time.
- the storage medium can be provided with an opaque layer on the side facing away from the adhesive layer and releasably attached to an opaque carrier material, such as a postcard, with the adhesive layer.
- the exposure time within which an image is stored on a photochromic layer is preferably approximately 30 minutes.
- the photosensitive layer consists of several photochromic substances, each of which responds to visible light of different wavelengths, colored images can also be stored in the storage device according to the invention.
- An advantage of using photochromic materials is that the photosensitive material can be made reusable in a simple manner by exposure to UV light after exposure.
- a particular advantage when using photochromic substances is that extremely high resolution can be achieved, since only the molecular size of the photochromic substances is decisive for the resolution.
- the photosensitive layer on its side facing away from the adhesive layer is provided with a silver or gold reflective layer, in particular, which reflects rays that pass through the photosensitive layer back onto the latter. This measure leads to a more intensive exposure of the photosensitive material and thus to shorter exposure times.
- the photochromic layer When using photochromic substances, it makes sense to design the layer which is attached to the side of the photosensitive layer facing away from the adhesive layer in such a way that it is UV light-transmissive and only absorbs visible light. In this case, the photochromic layer can be brought into a state by irradiation with UV light from the side facing away from the adhesive layer, in which a further storage process may be possible.
- the adhesive layer is preferably formed as a self-adhesive layer, which is covered in particular by a removable protective film before use of the device.
- the storage device can be sold without difficulty, and the handling by the viewer is also easy to accomplish.
- the adhesive layer does not have to be designed as a self-adhesive layer, it is also conceivable, for example, that the memory device adheres to the screen only by means of electrostatic forces.
- the storage device is at least substantially transparent.
- a storage device can be used particularly effectively in a method according to point e), since in this case - provided the storage device is designed in such a way that the stored image information is developed immediately - the information displayed by means of partial symbols or a moving point of light is visible to the viewer the side of the storage device facing away from the screen arises. In this case, however, it is necessary to use a material as the storage medium which only has a photosensitive layer on the side facing the screen, since otherwise the extraneous light not coming from the television screen would cause incorrect exposure of the storage device.
- a photosensitive material which is photosensitive from both sides can be used for the sake of simplicity, since the storage device can then be provided with an opaque layer on the side facing away from the screen, for example. Any text or symbol can then be printed on this layer so that it is visible to the viewer and is then visible to the viewer during the entire time in which the storage device is attached to the screen.
- the transmitter logo can be displayed, or it would also be conceivable to use this side of the storage device facing away from the monitor as advertising space, which is particularly useful in the case of a method according to c), since the company emblem of that company is attached to the storage device, for example in whose commercial the symbol to be saved is sent.
- the storage medium is frequency-selective, so that it only reacts to defined light wavelengths, for example to light wavelengths of a certain color.
- This has the advantage that the symbol to be stored does not necessarily have to be broadcast on a black background, but can appear directly on the broadcast television picture, since the colors of the symbol can be chosen so that they do not or only to a small extent the actual television picture occur, so that the television picture forming the background of the symbol does not cause the storage device to be incorrectly exposed.
- At least one plastic lens which is preferably designed as a Fresnel lens, can be arranged between the screen and the storage medium. Such a lens can be integrated into the layered structure of the storage device according to the invention without difficulty.
- the lens can be used, for example, to focus the symbol blurred on the screen so that it is sharply imaged on the storage medium.
- a lens which is designed as a decoding lens and which decodes a symbol that is shown in coded form on the screen on the storage medium.
- Such a lens could also preferably be used in a method according to point e), since it is then possible to dispense with representing the symbol to be stored in the form of partial symbols or in the form of a moving light point.
- the storage device according to the invention can be designed in such a way that the developer making the stored image information visible is integrated in the storage device, or that the stored image information can subsequently be developed by means of a developer layer or developer liquid which can be connected to the storage device.
- the storage device according to the invention is mounted on a carrier material made of paper, cardboard or laminated cardboard at the time of acquisition by the viewer, which in particular has a postcard format.
- the storage device can be sold in a particularly handy manner, and at the same time, after exposing the storage device, the viewer has a, in particular postcard-like carrier material on which he can reattach the exposed storage device and by means of which it can be sent back to the television station.
- the storage device is releasably attached to the postcard-shaped carrier material by means of its adhesive layer.
- the provision of a protective film covering the adhesive layer can be dispensed with. After the storage device has been exposed, the adhesive layer can also be used again to attach the storage medium to the postcard-shaped carrier material.
- the carrier material preferably has at least one development area in which a chemical substance for developing the image stored on a storage medium is integrated and on which the storage medium can be attached, in particular by means of an adhesive layer, after exposure.
- the development of the stored image information takes place immediately after the exposed storage device has been reattached to the postcard-shaped carrier material, as a result of which a separate development of the image information to be carried out by the viewer or by the television station is avoided.
- the carrier material can be formed in particular from foldable paper or cardboard, which makes it possible to cover the storage device on both sides by a corresponding folding of the carrier material by the carrier material and thus to make it impossible to expose both the front and rear sides thereof. This is particularly advantageous if photochromic materials are used as the photosensitive material which are not protected on the side facing away from the adhesive layer by a layer that is impermeable to visible light.
- Decoding lens can be made visible to the viewer.
- Such a decoding lens can be either attach it to the screen using an adhesive layer or hold it in front of the screen in a magnifying glass-like frame, the last alternative being particularly suitable for children.
- the viewer can then dial a specific telephone number again, for example, or send a specific solution word to the television station.
- FIG. 1 shows a highly schematic front view of a monitor or a television screen 1.
- a circular disk-shaped storage device according to the invention is mounted directly on the screen, which covers a partial area of a television image that can be displayed on the screen.
- FIG. 2 shows a greatly enlarged section A - A through a memory device 2 according to FIG. 1 before it is attached to the screen.
- the storage device 2 is built up in layers, the adhesive layer 4 on the screen side being covered by a protective film 5 before use of the storage device 2, which protective film 5 can be removed from the adhesive layer 4 in the direction of the arrow by the user of the storage device. With the adhesive layer 4 exposed after the protective film 5 has been removed, the storage device 2 can then be attached to a screen.
- a focusing lens 7 adjoins the adhesive layer 4, by means of which the television image blurred on the focusing screen is focused in such a way that it is sharply imaged on the photosensitive layer 3.
- the photosensitive layer 3 and the focusing lens layer 7 there is a layer which acts as a decoding lens and by means of which information displayed on the screen in encrypted form can be decryptedly reproduced on the photosensitive layer 3.
- the photosensitive layer 3 is followed by a developer layer 6, by means of which the photosensitive layer 3 is developed immediately after its exposure.
- All layers are preferably made of flexible material, which in particular makes it easier to detach or remove the storage device from a screen.
- the carrier material 8 can for example be made of cardboard and have the format of a postcard.
- the storage device according to the invention can be sold in a particularly advantageous manner, since it can be used on the one hand as a carrier material for the sale and on the other hand also as a carrier material for returning the exposed storage devices.
- the storage devices 2a and 2b are detachably arranged on a specific area of the carrier material 8. Adjacent to this area is a further area 9a and 9b, in which a developer material is integrated, by means of which the storage devices 2a and 2b can be developed after their exposure. After their development, the storage devices 2a and 2b can remain on the areas 9a and 9b and, together with the carrier material 8, can be sent to the television transmitter as a postcard. A single or also a plurality of storage devices can be sold with the carrier material 8. Corresponding to the number of storage devices arranged on the carrier material 8, the same number of development areas 9a and 9b must then also be provided on the carrier material 8.
- the development areas 9a and 9b on the carrier material 8 can be dispensed with.
- the address of the television transmitter is preferably printed on the back of the carrier material 8, not shown.
- the device according to the invention can also be used in connection with a computer monitor.
