In the article the process of automated image preparation for multimedia reproduction is discussed. In general, the original and the copy have different dynamic ranges due to the technical properties of the particular visualization system. The problem of reproduction of contours with contrast close to the threshold of distinction is investigated. It is noted that there may appear two types of distortion of information, when reproducing with a change in the dynamic range of the image: in the copy the contours may appear, which are missing in the original and, conversely, the contours present in the original may disappear in the copy. The concept of contour contrast is introduced, on the basis of which the algorithm of automated image processing is proposed. The algorithm ensures contrast preservation of contours close to the threshold of perception, which allows accurate reproduction of contour information. The program implementation of the proposed algorithm is performed.
