PCT No. PCT/DE81/00027 Sec. 371 Date Sep. 9, 1981 Sec. 102(e) Date Sep. 9, 1981 PCT Filed Jan. 24, 1981 PCT Pub. No. WO81/02205 PCT Pub. Date Aug. 6, 1981.The invention relates to a method and to a circuit arrangement for the partial recorrection of color recognition spaces in color recognition. Before the color recognition, the color coordinates (color locations) of characteristic sample points are determined in the colors to be recognized and sample color numbers are allocated to them, said sample color numbers being deposited in a color recognition memory. All color numbers of the remaining color locations of the color space are determined from the sample color numbers and are likewise stored. The respective color locations or, respectively, memory locations occupied with the same color numbers form a color recognition space within the color space. For subsequent boundary correction of a color recognition space, at least one auxiliary color sample is taken from a color to be recognized in the area of the desired change and the necessary sample color number is allocated to it. The color numbers within a spatial cancel area around the color location of the auxiliary color sample are cancelled and, upon incorporation of all sample color locations and sample color numbers, new color numbers are instead calculated and stored for the cancel area.
