Abstract
PURPOSE: To separate colors of image at high precision and high speed, by simple processing, by writing hue and saturation at each image point into two-dimensional decision table and lightness into one-dimensional decision table, and retrieving the tables.
CONSTITUTION: An image input device 1 consists of color drum scanner and color flying spot scanner, and data of three primary colors of red, blue and green are input from the image to be processed. From the inputted color data, a data converting device 2 computes the two-dimensional quantity corresponding to the hue and saturation and the one-dimensional quantity corresponding to the lightness. A color decision device 3 determines two-dimensional and one-dimensional decision tables, writes into the memory, and retrieves the tables for the quantity calculated from the color data on the decision tables. By using the device which decides the color on each image spot, the colors of the image to be processed may be separated at high precision and high speed by simple processing.
