Device for recording and reproducing multicolor images. Patented in the German Empire on June 19, 192S.

According to the Union Treaty of June 2, 1911, priority is due to this application of the application in France of June 27, 1924.

The invention relates to a device for recording and reproducing multicolor

rere partial filters composed color disc in the lens. With the help of such filters

images on films with a ribbed surface j arise on the photosensitive layer or with a net-like base (French carriers by refraction of the rays of light behind Patent 399762) behind one of several! each lenticular diffuser

Broadening of the individual partial color images that overlap each other. Around To prevent this is according to the invention with that containing the three partial colors Light filter in the lens a disc with narrow, parallel or star-shaped attached dark stripes united, which separate the partial colors of the filter in the lens from each other separate.

The drawing gives an exemplary embodiment for this.

Fig. Ι shows a three-colored (red, green, blue) diaphragm (diaphragm) in the form of a ribbon, Fig. 2 a three-colored aperture in sector form.

Fig. 3 shows a filter in the form of a ribbon and

Fig. 4 shows a filter in the form of a sector. Fig. 5 is a section through the emulsion. Fig. 6 shows a view corresponding to Fig. 5 from the front.

The photosensitive layer 4 of the recording plate or film is spherical Elevations 3 provided. Each of these elevations gives an image of a three-color image on the photosensitive layer 4 in the objective attached filter 2. By scattering the light rays arises on the photosensitive layer after the development a zone on which two partial color filters acted at the same time.

The zone of dispersion A affects the color perception when reproducing the

Original film almost entirely. The scattering can be avoided by attaching a disk (Fig. 3 and 4), which is united with the filter. The disc has the same Diameter like the multicolor filter and is with dark stripes /? provided, their location that of the three-color filter, e.g. B. in a parallel arrangement (Fig. 3) accordingly the filter according to Fig. 1 or in a star-shaped (Fig. 4) according to the color filter Fig. 2.

These with stripes /? provided disc is with the three-color filter 2 at the time of recording of a multicolor film.

During the production of the original film, the strip disk B is attached to the lens. When reproducing Urfihnen, it is advisable to attach a lens with an opening of approximately ι: 2 in connection with the stripe disk.
