METHOD FOR DISCRIMINATING COLOR AND DEVICE FOR DISCRIMINATING COLOR

摘要

PURPOSE:To accurately discriminate color of an article to be detected having uneven surface such as woven and knit fabric by outputting detected signals when difference of level of each comparative signal operated based on the detection signals exhibiting RGB mixing amount of detected color is determined to be within a prescribed range. CONSTITUTION:Signals which detected RGB mixing amount of a color article to be discriminated is output to a detecting, comparing and setting part in RGB detection part of three original color of red, green and blue having plural color sensor elements. In the above-mentioned setting part, percentage of reciprocal number of ratio of the above-mentioned RGB mixing amount is multiplied by voltage output by the above-mentioned each color sensor and the result is sent as comparison signals to comparing and detecting part and difference of level of each comparison signal of R to G, B to G and R to B is controlled. When the difference of the level is judged to be within a prescribed range in a comparator, a desired color is regarded as to be discriminated by a detection signal output part and detection signals are output.
