Abstract:
1. A method for adjusting colors of an image, in particular of an X-ray image in which an object having sub-objects shown in different colors is depicted, comprising the steps of: determining an X-ray absorption attribute of a plurality of the sub-objects; assigning a specific color to each of the plurality of sub-objects on the basis of an average atomic number; adjusting a brightness level of one of the specific colors by adjusting each pixel thereof with a determined color proportion of at least one of red, green or blue, whereby the adjustment of the brightness level takes into consideration the sensitivity of the human eye; and displaying at least the plurality of sub-objects having the same X-ray absorption attributes on a monitor, whereby adjustment of the brightness level of one of the specific colors causes the human eye to view at least the plurality of sub-objects as having equal brightness levels, wherein the brightness level of at least one of the specific colors, which is assigned to a sub-object, is adjusted if the X-ray absorption attribute associated with the sub-object is substantially equal to the X-ray absorption attribute of another sub-object.
