Definitions

  • the invention relates to a device for storing image information, in particular a code, displayed on a partial area of a monitor, with a storage medium made of photosensitive material that can be attached to the monitor surface by means of an adhesive layer effective on the monitor side.
  • German patent application P 43 12 185.3 Such a device is known from German patent application P 43 12 185.3.
  • the object of the invention described in this patent application was to create a device with which any type of television program can be made more interesting, with which the viewer is encouraged to participate and about which the television transmitter provides information about can receive the broadcast participation.
  • this device presents the problem that the information displayed on the screen is blurred on the screen surface due to the thickness of the glass bulb of a screen, so that in certain cases the information displayed cannot be stored absolutely sharply on the photosensitive material.
  • this object is achieved in that the photosensitive material is applied to a flat carrier medium and is only effective there on the monitor side in certain, spaced apart areas.
  • a masking or diaphragm layer in particular a focusing effect, in particular a pinhole layer, which is translucent in the effective areas and opaque in the areas lying between the effective areas is, and / or
  • the provision of the effective and ineffective areas according to the invention ensures that light emitted by the monitor triggers a storage process only in the effective areas, the corresponding areas of the photosensitive material being delimited from one another by the ineffective areas .
  • the feature according to the invention comprises all possible arrangements of carrier medium and photosensitive material in which light coming from the monitor triggers a storage process in the photosensitive material, ie the photosensitive material Material can be on the monitor side of the carrier medium as well - e.g. B. when using a transparent carrier medium - be arranged on the side of the carrier medium facing away from the monitor.
  • a symbol is displayed on the screen, the geometry of which is selected such that only very specific effective areas of the photosensitive material are exposed. If a certain number of effective areas is provided (for example six to twelve), certain codes, in particular two or three different brightness levels, can thus be displayed on the screen and stored in the photosensitive material, one code each having a specific arrangement corresponds to light and dark areas within the emitted symbol. Due to the targeted arrangement of the bright areas on the screen, only corresponding, opposite effective areas of the photosensitive material are exposed.
  • This method can be used, for example, to determine during the evaluation of the storage device what type of program a viewer has seen, if this program a specific symbol of the type mentioned is assigned. In the manner described, a code identifying a program can therefore be stored in the photosensitive material, it then being possible to check whether the storage device according to the invention was attached to the screen while the program was being broadcast.
  • a non-photosensitive carrier material for example a film
  • photosensitive material is applied in a very targeted manner only in those areas which are ultimately intended to be suitable for storing image information.
  • These areas then represent the effective areas according to the invention, which are delimited from one another by ineffective areas, to which, accordingly, no photosensitive material has been applied.
  • the translucent areas of the mask or diaphragm layer on the photosensitive material mark those effective areas on which image information can be stored.
  • the light can only reach the photosensitive material through the translucent areas and the possibly existing areas of the photosensitive material covered by the opaque areas cannot be exposed.
  • the mask or diaphragm layer can consist of an at least largely opaque material, for example paper, cardboard or plastic, or can also be applied to the carrier medium by means of a coating process.
  • the sharpness of the stored image can be increased by forming the mask or diaphragm layer in such a way that a focusing effect is achieved by it.
  • the translucent areas can each be formed, for example, by a recess, preferably by a perforated or slit diaphragm.
  • a multiplicity of such perforated and slotted diaphragms preferably between 3 and 500 substantially circular recesses forming individual perforated diaphragms being provided.
  • the recesses or the effective areas are arranged substantially regularly distributed around the center of the mask or diaphragm layer.
  • the thickness of the diaphragm layer is to be selected depending on the sensitivity of the photosensitive material, the size of the recesses provided in the diaphragm layer and / or the sharpness of an image displayed and to be stored on the surface of a screen. It can the aperture layer becomes thinner the more sensitive the photosensitive material is or the smaller the recesses provided in the aperture layer are.
  • a problem to be solved within the scope of the invention stems from the fact that the glass bulb of a screen has a certain thickness, which means that the images produced on the inside of the glass bulb are imaged blurred on the outer surface of the glass bulb .
  • the aforementioned aperture layer is provided, for example, which brings the image into focus on the photosensitive material.
  • the focussing effect must be stronger the thicker the glass bulb of the screen, which is why the thickness of the diaphragm layer can also be made smaller as the glass bulb becomes thinner.
  • the thickness of the diaphragm layer is approximately 5 mm.
  • 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, a mask or diaphragm layer and an adhesive layer can only be 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 circular disk, but any other contours, for example essentially circular or polygonal, in particular quadrangular, hexagonal or octagonal, can also be envisaged. - for example, it is also possible to give the storage device the shape of a transmitter logo or some other advertising-effective shape, in particular a shape typical of a particular company.
  • the outer contour of the mask or diaphragm layer essentially corresponds to the outer contour of the carrier medium.

  • Photochromic substances are preferably used. These are characterized in 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 with the adhesive layer on an opaque carrier card, such as a postcard.
  • the exposure time within which an image is stored on a photochromic layer is preferably approximately 30 minutes, but is dependent on the one used photochromic material or variable depending on the brightness of the emitted image.
  • 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 substances is that the photosensitive material can be made reusable in a simple manner by irradiation with UV light after exposure.
