  • Patent number: 4418390
    Abstract: A method and apparatus are disclosed for making a coded chart of a color subject for use in creating a likeness of the subject by needleworking. An image of the subject is formed on a screen. The image is scanned, point by point, with a fiber optic probe and the light received by the probe is measured for color content using a set of phototubes and color filters. The analog output signals from the phototubes are converted into digital signals and fed into a computer where they are processed to determine the proper color needlecraft material to use for each picture element in the subject. Using this information, an image of the subject is produced on the display screen of a computer terminal, with each picture element in the image appearing as a symbol identifying its particular color. In addition, a color reproduction of the subject based on the color signals is generated on a color monitor.
