摘要
The invention relates to method and device for processing colour information of a pattern having cluttered and useful information characters. According to said invention, the digital pattern picture comprising display points whose colour is defined by brightness, saturation and hue values is produced. At least one first type picture area is selected in such a way that it corresponds to the pattern area containing clutter characters without useful characters. The brightness value area, saturation value area and the hue value area are defined according to said first type picture area. The colours of the display points of the first type picture area whose brightness, saturation and hue values are arranged in the corresponding value areas are classified in the first colour class related to the clutter characters.
