    摘要: An apparatus and a method for the recognition of colors on a colored image illuminated with a light source of a known spectrum composition, wherein the intensities of three primary colors are measured opto-electronically as color components, which represent the spatial co-ordinates of the color locations in a color space. Prior to color recognition the color components of at least one characteristic test point in each color or color region, which is to be recognized, are measured and noted. The test color components represent the corresponding test color locations in the color space. An identification symbol is assigned to each color component triplet of the test points and noted too. The plurality of color locations in the color space are associated automatically with identification symbols in dependence their respective positions with respect to a spatially close-by test color location, whereby all color locations associated with the same identification symbol appertains to one color recognition region within the color space. Then the colored image is scanned opto-electronically for actual color recognition and the color components thereby obtained are compared with the color components noted, and in case of correspondence, the corrresponding assigned identification symbol is read out, whereby the color components of the colors are verified regarding their correspondence to one of the defined color recognition regions of the color space.

    摘要: A method and an apparatus are provided for contrast intensification in the reproduction of masters in the field of electronic image processing by engraving devices and scanners. In the image-point-wise, opto-electronic master scanning, two outer field signals are obtained in addition to the image signal by scanning a first outer field and a larger, second outer field. A first differential signal and a second differential signal are generated from the image signal and the outer field signals and a third differential signal is generated from the two outer field signals. The first differential signal is combined with at least one of the other two differential signals to form an auxiliary signal which is added to the first differential signal in order to obtain a correction signal. The correction signal is then superimposed on the image signal for the purpose of contrast intensification. By employing a second outer field signal, it is particularly the disturbing edges around hard master contours which are avoided.
