ABSTRACT:
A method and apparatus for generating a pattern for making rugs corresponding to a predefined image. The predefined image is scanned by a video camera to generate a video image corresponding to the predefined image. A frame grabber captures one frame of the video image. The captured image is isolated and compressed by a CPU into a compressed image corrresponding to the video image and having a limited number of subareas, each subarea having a color. The CPU compares the color of each subarea to the colors in a look-up table to define a 48-color image. A printer creates from the 48-color image the pattern corresponding to the predefined image and an inventory identifying the numbers and colors of yarns needs to make a rug from the pattern.
