Abstract:
An image reproducing method, wherein an image signal represents an image of an object, a first visible image is reproduced by a first image reproducing means and from a first processed image signal which has been obtained from image processing carried out on the image signal, and a second visible image is reproduced by a second image reproducing means and from a second processed image signal which has been obtained from image processing carried out on the image signal, the second image reproducing means having gradation characteristics in image reproduction which are different from gradation characteristics in image reproduction of the first image reproducing means, the method comprising the steps of:i) preparing first reproduced image processing conditions which cause the first visible image to have a desired level of gradation when the first visible image is reproduced by the first image reproducing means, and corresponding second reproduced image processing conditions which cause the second visible image to have a desired level of gradation when the second visible image is reproduced by the second image reproducing means,ii) in the event the visible image is reproduced by the first image reproducing means in accordance with the first reproduced image processing conditions, carrying out image processing on the image signal under the second reproduced image processing conditions, which correspond to said first reproduced image processing conditions, so as to obtain said second processed image signals andiii) reproducing the second visible image by the second image reproducing means from said second processed image signal,wherein the first reproduced image processing conditions and the second reproduced image processing conditions are each prepared in accordance with a portion of the object to be imaged, the pattern of said portion being embedded in the image.
