Abstract

Abstract An optical scanner generates facsimile signals. Each pixel of a scanned image is observed by separate fiber optic elements at different times. Each fiber optic collector directs the light through a color filter and the thus filtered light is detected. Separate color signals are then correlated to associate respective colors with each pixel of the scanned image.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 150 words
An optical scanner for scanning an image and providing separate color outputs comprising: a plurality of optical fiber light collectors, there being a separate optical fiber collector associated with each of said color outputs, each light collector collecting light from a discrete area of the image which is distinct from areas associated with other light collectors at each instant of scan; a lens for imaging the image onto the end faces of the optical fiber collectors; means for detecting and providing an electrical output of the amount of light of a respective color collected by each optical fiber light collector; means for causing relative movement between the optical fiber light collectors and the image; and means for correlating the electrical outputs as a function of the speed of relative movement between the optical fiber light collectors and the image to associate respective colors with each discrete area of the image.
Claim 2
Dependent Claim 150 words
An optical scanner for scanning an image and providing separate color outputs comprising: a plurality of optical fiber light collectors, there being a separate optical fiber collector associated with each of said color outputs, each light collector collecting light from a discrete area of the image which is distinct from areas associated with other light collectors at each instant of scan; a lens for imaging the image onto the end faces of the optical fiber collectors; means for detecting and providing an electrical output of the amount of light of a respective color collected by each optical fiber light collector; means for causing relative movement between the optical fiber light collectors and the image; and means for correlating the electrical outputs as a function of the speed of relative movement between the optical fiber light collectors and the image to associate respective colors with each discrete area of the image.
Claim 3
Dependent Claim 16 words
An optical scanner as claimed in claim 1 wherein the image is carried by a drum.
Claim 4
Dependent Claim 48 words
An optical scanner as claimed in claim 2 wherein optical fiber light collectors associated with respective colors are positioned in line parallel to the direction of movement of the image on the drum, and the means for correlating the electrical outputs responds to the speed of the drum.
Claim 5
Dependent Claim 37 words
An optical scanner as claimed in claim 1 wherein the optical fiber light collectors are in line parallel to the direction of image movement, and the means for correlating responds to the speed of the image movement.
Claim 6
Dependent Claim 26 words
An optical scanner as claimed in claim 1, 3 or 4 wherein the means for correlating comprises means for delaying certain of the electrical output signals.
Claim 7
Dependent Claim 27 words
An optical scanner as claimed in claim 1 or 2 in which the means for detecting includes a color filter between the image and a photoelectric detector.
Claim 8
Dependent Claim 43 words
An optical scanner as claimed in claim 1 or 2 wherein the collecting end of each optical fiber collector is mounted for movement on a scanning head and the other end of each optical fiber is stationary adjacent to a stationary photoelectric detector.
Claim 9
Dependent Claim 17 words
An optical scanner as claimed in claim 1 or 2 further comprising an ink jet printer assembly.
