Abstract
A method for the transformation of image signals that have been obtained by color filtering and have been logarithmically compressed is proposed. The color saturation of the recorded images is increased thereby. According to one aspect of the invention, the transformed image signals are determined as a function of the logarithmically compressed image signals and the logarithmically compressed brightness signals for a spectral color.
