Abstract
A method for imaging an area of investigation is based on a source half-tone picture of the area of investigation. The source half-tone picture is composed of individual picture elements to which are allocated the source gray scale values corresponding to the morphology of the area of investigation. A framing mask operation produces modified gray scale values from the source gray scale values as a function of a preassigned brightness value and a preassigned contrast value which are fed to a display device. The preassigned contrast value is controlled as a function of the preassigned brightness value or the preassigned brightness value as a function of the preassigned contrast value.
Claims23
A method for displaying an image in a viewing area having viewing conditions, comprising the steps of:
- producing a source half-tone image composed of a plurality of individual picture elements;
- allocating respective source grayscale values to all of said picture elements for obtaining source grayscale values for an entirety of said source half-tone image;
- predetermining a plurality of combinations of brightness values and contrast values which produce an artifact free image and storing said combinations, as stored combinations;
- setting a brightness value dependent on said viewing conditions, as a set brightness value, and conducting a framing mask operation on each of said source grayscale values for producing modified grayscale values from each of said source grayscale values using only said set brightness value and said stored combinations;
- and
- feeding said modified grayscale values to a display device for displaying an artifact-free modified grayscale value image corresponding to said source half-tone image.
