In a method and apparatus for generating a combined parameter map from a number of individual, initial parameter maps that contain values of various parameters dependent on the position (x, y), for each of the initial parameter maps and for each position, the signal value of the parameter at the appertaining position is converted into a first color value according to a first transfer function specifically defined for the respective parameter. Subsequently, the first color values are respectively converted into color code intensity values on the basis of a second transfer function. The color code intensity values of the individual parameters are then operated to form a combined intensity value. Finally, the combined intensity value is converted with a third transfer function into a color value at the appertaining position in the parameter map.
