Method and apparatus for recording color picture information on photographic material
Abstract
Abstract A method of recording color picture information from an original scene on a film having a single layer of photosensitive emulsion containing a mixture of silver halide grains of different spectral sensibilities. The film is exposed in an optical camera to record a first series of monochrome images of the luminance content in the original color picture scene and a second series of monochrome images which are to represent the color content of the scene. The film is thereupon treated in a laboratory, and such treatment involves a reversal process including the exposure of a color raster onto the film portion which is provided with the second series of images. The spatial frequency of the color raster corresponds to the desired scanning frequency for the purpose of reproducing the images by color television scanning techniques.
