Abstract
A method and apparatus for analysis of an image original to be reproduced by evaluating image values (R, G, B) acquired by the point-by-point and line-by-line, trichromatic scanning. The image values of a first color space allocated to the input apparatus are transformed into image values of a second color space that is independent of the first color space. The analysis of the image original for calculating setting values for image processing is implemented on the basis of the transformed image values of the second color space. The master analysis on the basis of the image values is implemented in view of image scope, image gradation and/or color cast.
