Definitions

  • the invention relates to a method for image storage and image projection and devices for performing the method.
  • Magnetic tape recording requires a high tape speed to resolve the electronic signals, which is why in addition to the tape feed - to a cheaper one. Frequency range to come - must still have the scanning heads rotated diagonally or transversely to the tape feed in order to achieve a sufficient demonstration time. Magnetic plates up to a diameter of 30 cm currently bring only relatively short demonstration times and cannot be used for 1 1/2 hour demonstration times.
  • the currently known methods of magnetic tape / disk and color-Schmaifila sampling are technically satisfactory, but cannot reach a wide range of buyers due to the high cost of the equipment.
  • the invention is therefore based on the object of specifying a method for image storage and image projection as well as devices for carrying out this method, which is considerably less expensive than the known methods or devices.
  • a 16 mm wide plastic film strip is used, which consists of crystal-clear and / or coated material, the method itself retaining the advantages of photoelectronic reproduction.
  • the image carrier however, a path has not yet been realized due to the lack of technical feasibility.
  • the plastic film tape used in the method proposed here carries next to each other: a) 2 synchronous tracks S-1 and S-2, which are located on the outside of the film tape edges and are, for example, about 0.5 mm wide and for controlling the film transport and Serve image switching. b) 4 wide image content tracks, one is reserved for the red, the green, the blue and the black and white image content. c) In the middle of the tape there are 2 more narrow tracks T-1 and T-2 for stereo playback.
  • FIG. 1 Devices suitable for film scanning are shown in FIG. 1
  • FIG. 2 shows a device for carrying out the method, in which a crystal-clear plastic film strip is used
  • FIG. 3 shows a device according to FIG. 2 with a switching device for delaying first sampled color signals
  • It has the picture content tracks RS, GS, BS as well as the synchronous tracks S-1, S-2 and the sound tracks T-1, T-2.
  • Light spot scanning tube LIAR through which a cell-shaped light line LISI is passed over the film strip F3, if a crystal-clear film strip F3 is used, as shown in FIG. 2, the scanning light of the tube LIAR passes through the film strip FB, is from a cylindrical lens ZYL taken over and imaged by a prism PRS or mirror on a row-shaped photodiode array circuit CCD, consisting of a row of about 1728 photodiodes.
  • the evaluation of the converted light signals into electrical signals takes place in an evaluation circuit AWS.
  • the line-shaped scanning of the scanning tube LIAR which is controlled by a horizontal deflection system, takes place synchronously with the read line reading of the array circuit CCD.
  • the 16 na wide, crystal-clear (and / or coated) foil tape FS contains the color image contents for the 3 color colors and a black and white Image and the two synchronized and sound tracks printed.

  • the four colors are not superimposed, but in separate columns, either only side by side or printed on the front or back of the foil tape FB.
  • a clear film strip FB is used, a light line is projected as a line through the film strip FB through the light spot scanning tube LIAR (FIG. 2).
  • the image contents are on the film tape F3 as halftone color separations, in separate tracks.
  • the red-colored picture contents RS are printed in red, the green-colored picture contents GS in their associated track in green color, the blue-colored picture contents in the associated track BS in blue color and the black-and-white picture content in the last wide track SWS in black- white shades of gray.
  • the signals produced at the output of the scanning tube LIAR correspond to the RGB matrix signals of a conventional color video tube circuit, in a row.
  • the first sampled blue and green signals BS and GS must be delayed to such an extent that they are fed to the picture tube or the screen at the same time as the red signal RS. This is done by the evaluation circuit AWS (Fig. 3 and 4).
  • the light spot scanning tube only has to travel the path designated COLA in FIG. 1. If only black and white images are to be reproduced, the light spot scanning tube only scans the line path labeled SWA.
  • An associated magnetic deflection circuit SORA generates the line-shaped, horizontal deflection of the scanning tube LIAR, the signals of which are applied by the horizontal oscillator OS.
  • the image contents are printed side by side in four different color columns on the film strip FB.
  • the 4 picture contents in and of themselves in one, as high-contrast as possible Color, eg in black-white or in gray-tinted eal tones, can be printed on the foil tape FB, since the photodiodes of the array circuit CCD are only able to register gray tones anyway.
  • the image content can therefore be in a row in succession transversely to the transport direction or also along the transport direction of the belt FB in analog form, e.g. as rungs or serrated letters, or also in digitized form, are printed on the foil tape FB side by side and in rows.
  • the image and traffic lane contents on the film strip FB can be deflected into a common optical channel by appropriate devices.
  • the width of the image tracks is only 4 mm and is therefore somewhat narrower than with the Super 8 narrow film. This would deteriorate the image quality compared to the Super 8 narrow film.
  • an opaque film bath has the advantage that it has a high-contrast coating provided with an optimal, improved APCO standard coating, so that it can be printed in fine and reprint. Since the foil tape FB is 16 mm wide and then only 2 image and 2 control or syuchron tracks are arranged on each side, the image width is now approx. 6 mm, which is a lot wider than with the Super-8- Narrow film.
  • FIG. 4 shows an exemplary embodiment for the light paths of this scanning form.
  • the light spot scanning tube LIAR generates a cell-shaped scanning beam, which is deflected on one half (in FIG. 4 above) from a full mirror VSP to a waist-permeable mirror HSP and is projected onto the rear (redo-drying) of the film hand FB.

  • foil tape FB is to be used without perforation, although a perforated version can also be used, and since it is possible to dispense with jerky transportation of the foil tape by Maltese cross or gripper system, a continuous foil tape feed is provided.

This is an improvement over the ratio of the Super 8 narrow film, in which the existing image quality, which is determined by the skill of the photographer, is given and is unchangeable. By weakening or intensifying the color application on the film strip FB, the image quality in the present invention can also be subsequently corrected and improved, which is practically impossible with the Super 8 narrow film.
  • the resulting longer strap length is so important in terms of the material price. If necessary, it would even be possible to double the image length so that the length of the line is double. Although the total tape length is doubled and the tape cassette becomes larger, the doubling is still reasonable in terms of price. finally, the light-optical projection paths are shown, which make it possible to work from a single light source, e.g. Using an xenon spot light blitx tube to illuminate all 3 color paths plus the fourth black and white image path by mirroring.
