Abstract
Abstract A camera apparatus for reproducing a color picture on monochromatic film with stripe patterns of a filter wherein the filter is placed in the light path of the camera and the stripe patterns correspond to the primary color components of the object. The filter comprises a single filter element which includes strip filter elements of different types with a first filter element being capable of transmitting visible light of all colors, a second filter element capable of transmitting light of only one color, a third filter element capable of transmitting light of a single color different from the first color and a fourth filter element capable of transmitting light of a color different from the other two colors.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
235 words
Apparatus for producing monochromatic film from color images which can be utilized in a television system having means for scanning a beam in a particular direction to reproduce electrical signals containing color information comprising, an optical system through which said color images are passed, an unexposed monochromatic film for recording the focused real image of an object produced by said optical system, an optical filter in said optical system between said monochromatic film and color images and said filter formed of a first plurality of strips capable of passing visible light of all wavelengths, a second plurality of strips spaced between said first plurality of strips capable of transmitting visible light of one color, a third plurality of strips interspaced between said first and second plurality of strips capable of transmitting visible light of a second color, and a fourth plurality of strips interspaced between said first, second and third plurality of strips and capable of transmitting visible light of substantially a third color, said first, second, third and fourth plurality of strips extending in the same direction, and the orientation of said scanning beam, said filter and said monochromatic film being such that when said monochromatic film has been exposed and developed said scanning beam traverses on each scanning pass across the portions of said film which were exposed through each of said first, second, third and fourth plurality of strips of said filter.
