Color information on black and white film

Claim 5

Apparatus for reproducing a color image code on black and white film in a plurality of contiguous rectangular regions each having three and only three non-white portions in each region extending the length of said film and each including a red coded rectangular portion of a first width, a blue coded rectangular portion of a second width differing from said first width and a green coded rectangular portion of a width differing from said first and second widths comprising: means for scanning a source of light across the width of said film so each scan causes said source to sequentially encounter at least a part of each of said red, blue nd green coded portions of each of said regions, means for detecting at least a portion of said source of light after said light has encountered said film and for determining the width of each portion scanned so as to determine whether that portion is red, green or blue coded, means for producing a reproduction of said image on a viewing screen with first means for causing red color to appear on said screen, second means for causing a blue color to appear on said screen and third means for causing a green color to appear on said screen, and means connected to said detecting means for operating said first means when said detecting means determines that said part being scanned is coded red, operating said second means when said detecting means indicates said part being scanned is blue and operating said third part when said detecting means indicates said part being scanned is green.

Claim 6

Apparatus for reproducing a color image code on black and white film in a plurality of contiguous rectangular regions each having three and only three non-white portions in each region extending the length of said film and each including a red coded rectangular portion of a first width, a blue coded rectangular portion of a second width differing from said first width and a green coded rectangular portion of a width differing from said first and second widths comprising: means for scanning a source of light across the width of said film so each scan causes said source to sequentially encounter at least a part of each of said red, blue nd green coded portions of each of said regions, means for detecting at least a portion of said source of light after said light has encountered said film and for determining the width of each portion scanned so as to determine whether that portion is red, green or blue coded, means for producing a reproduction of said image on a viewing screen with first means for causing red color to appear on said screen, second means for causing a blue color to appear on said screen and third means for causing a green color to appear on said screen, and means connected to said detecting means for operating said first means when said detecting means determines that said part being scanned is coded red, operating said second means when said detecting means indicates said part being scanned is blue and operating said third part when said detecting means indicates said part being scanned is green.

Claim 7

Apparatus as in claim 2 wherein said first, second and third means include electron guns.

Claim 8

Apparatus as in claim 3 wherein said detecting and determining means includes a photomultiplier for generating an electrical signal having an amplitude which is a function of the light incident upon said photomultiplier which in turn is a function of the light transmissive characteristic of said part being scanned.

Claim 9

Apparatus as in claim 3 further including a photomultiplier for sequentially detecting the light transmitted through each said part and for generating an electrical signal having an amplitude which is a function of the light incident upon said photomultiplier and means for transmitting said electrical signal to said electron guns.

Claim 10

Apparatus as in claim 3 wherein said electron guns are in a color television.

Claim 11

Apparatus as in claim 2 wherein said light source includes laser means for producing a red, green and blue beam and wherein said first means causes said laser means to produce said red beam but not said green and blue beams, said second means causes said laser means to produce said blue beam but not said red and green beams and said third means causes said laser means to produce said green beam but not said red and blue beams.

Claim 12

ApparatuS as in claim 7 wherein said producing means includes means for projecting the light transmitted through said film onto said screen.

Claim 13

Apparatus as in claim 8 wherein said detecting and determining means includes a photomultiplier for generating an electrical signal having an amplitude which is a function of the light incident upon said photomultiplier and including means for applying a portion of the light transmitted through said part to said photomultiplier.

Claim 14

Apparatus for reproducing a color image coded on black and white film in a plurality of contiguous rectangular regions each extending the length of said film and each including a red coded rectangular portion of a first width, a blue coded rectangular portion of a second width differing from said first width and a green coded rectangular portion of a width differing from said first and second widths comprising: means for applying a source of light to said film so as to generate a first diffraction pattern for said red coded portions, a second diffraction pattern for said blue coded portions separated from said first pattern and a third diffraction pattern for said green coded portions separated from said first and second patterns, means for detecting at least one of the images of each of said first, second and third patterns, for producing a red image from the image detected from said first pattern, a blue image from the image detected from said second pattern and a green image from the image detected from said third pattern, and for combining said red, blue and green images to reproduce said color images.

Claim 15

Apparatus for reproducing a color image coded on black and white film in a plurality of contiguous rectangular regions each extending the length of said film and each including a red coded rectangular portion of a first width, a blue coded rectangular portion of a second width differing from said first width and a green coded rectangular portion of a width differing from said first and second widths comprising: means for applying a source of light to said film so as to generate a first diffraction pattern for said red coded portions, a second diffraction pattern for said blue coded portions separated from said first pattern and a third diffraction pattern for said green coded portions separated from said first and second patterns, means for detecting at least one of the images of each of said first, second and third patterns, for producing a red image from the image detected from said first pattern, a blue image from the image detected from said second pattern and a green image from the image detected from said third pattern, and for combining said red, blue and green images to reproduce said color images.

Claim 16

Apparatus as in claim 10 wherein said detecting, producing and combining means includes a first sensing means positioned for detecting an image of said first pattern, a second sensing means positioned for detecting an image of said second pattern, a third sensing means positioned for detecting an image of said third pattern, a first electron gun responsive to the output of said first sensing means for producing a blue image, and second electron gun responsive to the output of said second sensing means for producing a green image and a third electron gun responsive to the output of said third sensing means for producing a red image.

Claim 17

Apparatus as in claim 11 wherein each of said sensing means is a photomultiplier.
