Abstract
A method of selectively assigning to a picture element to be imaged with a color reproduction system a pertinent (permanent) indication relating to the distinguishing of color with respect to picture element, wherein, on the basis of the associated parameter values related to color saturation and intensity, a choice is first made for that picture element from a permanent indication of colorlessness a permanent indication of color behavior, and a provisional indication concerning an undefined color behavior. In the case of a picture element having a provisional indication, this indication is then converted to a permanent indication on the basis of the results of an analysis of the distribution of parameter values in the color space with respect to picture elements occurring within an environment of the associated picture element. According to this method, pastel hues can be reproduced in a logical and perceptually acceptable manner despite the presence of scanner noise.
