Abstract

The available contrast of common display devices is much lower than image data often demand. Usually a variant of an average of the field of view is used to normalize the image. In this paper an alternative approach will be taken to define the mapping of rendered values to the displayable intensity range. The luminance range is chosen such that a minimum amount of information is lost, thereby preserving the contrast ratio of all correctly displayed parts. The loss of information can be regulated by different error functions. The introduced method can be applied on the color and gray scale images
