Method for generating smooth color corrections in a color space, particularly a CIELAB color space

摘要

Method for generating harmonic color corrections in a color image. The color image is deposited in an image store and is displayed on a monitor. Color samples of the colors that are to be subjected to a selective color correction are taken from the image with a coordinate input means. Color correction values that act on the colors defined by the color samples are input. In order to obtain harmonic transitions at the locations in the image where the selected colors meet non-selected, neighboring colors, the color correction decreases toward the edges of the color correction area. This is achieved by a filtering of the color samples or color correction values. A color computer calculates the corresponding color correction values.
