Definitions

  • the invention relates to a method of manufacturing a die for a picture carrier intended for creating the impression of a movement when the picture is projected or illuminated on at least certain parts of the picture or projection, by making use of a polarizer or an analyzer and a picture carrier treated accordingly.
  • US patent No. 3,437,401 describes a light box for animating selected parts of a picture, whereby use is made of a rotating polarizing disc and a light-interrupting foil, which is provided with several picture line patterns impressed on those parts of the foil that constitute the part to be animated. Said picture lines have been impressed on the light-interrupting foil by means of a die or a punch.
  • For the projection use is made in principle of one or more light sources, a polarizing disc rotating in front of said light sources and a picture carrier located in front of said polarizing disc, whereby the picture carrier is locally provided with parts acting as an analyzer.
  • Said parts acting as an analyzer made be made by providing certain tension lines according to a certain pattern, yet oriented in varying directions in the various locations.
  • a suitable selection of the material of the picture carrier or the foil will make it possible, by impressing tension lines, to obtain a polarizing effect, on the basis of the properties of the foil material itself. Furthermore it is possible to provide unevennesses, oriented in certain directions, on a foil of a suitable material and to provide an ink layer containing polarizing crystals on said foil. The orientation of said polarizing crystals will then adapt itself to the orientation of the unevennesses. With such a pre-treated foil it is also possible to provide a, possibly colourless, layer containing polarizing crystals before or after providing the coloured printing inks.
  • This known method is in particular suitable for producing a large number of identical light-interrupting foils.
  • a large number of intermediate steps are necessary, however, in order to provide the parts, oriented in various directions, of the picture in which a certain polarizing effect is to be effected.
  • a separate mask such as e.g. known from lithography, is to be used.
  • 3,437,401 can be realised in a very simple manner and with great accuracy, whereby it is no longer necessary to use a die and it is also possible to provide one or only a few picture carriers with a picture with the desired polarizing effect at very short notice. As a result of this separate polarizing pictures can be realised much faster and at much lower cost than before.
  • a light source in front of which a rotating polarizer is located, use may also be made of light sources of polarized light, whereby care must be taken that the orientation of the polarized light is changed after all, e.g. by means of an analyzer disc. It is possible to irradiate the picture or the picture carrier itself with light, so that the picture itself is directly observed by the observer, in the shape of a light box or a neon sign in a shop window. In the latter case the light source may be placed at some distance. For projection systems, however, the light shining through or being reflected, as is e.g. the case with an overhead projector, will be projected on a viewing screen.
  • Patent Abstracts of Japan, vol.11, No. 68 (P-553), February 28, 1987, and JP-A-61 231531, October 15, 1986 describe a method for manipulating a video film, for example, with the aid of mirrors.
  • a picture of a film is provided with another background, for example, and this manipulation is recorded on film or videotape.
