ABSTRACT:
A method for selective color correction of a color image that is deposited in a store and is displayed on a monitor. Color samples of the colors that are to be corrected are taken from the image with a coordinate input means. The color samples are deposited in a color sample memory and form a cloud in a CIELAB color space. This cloud usually has gaps and singular dots. In order to avoid discontinuities, the cloud is filtered and the gaps and singular dots are thus removed. The arrangement of the color samples in the color space can be displayed in a dialogue window in that color correction values are also input. A color computer uses the color samples and the color correction values for the selective color correction of the image. The image corrected in this way can be stored in the store and can be used for the production of color separations.
