  • Method for imaging an area of investigation
    Patent number: 6151418
    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.
