of the area of investigation, the source half-tone picture being
composed of individual picture elements, wherein the picture
elements are allocated source gray scale values corresponding to
the morphology of the area of investigation, and employing a
framing mask operation which produces modified gray scale values
from the source half-tone pictures as a function of a
preassigned brightness value and a preassigned contrast value,
which are fed to a display device. According to the invention,
the preassigned contrast value is controlled as a function of
the preassigned brightness value or the preassigned brightness
value is controlled as a function of the preassigned contrast
value. By this method, the source half-tone picture can be
presented automatically free from artifacts with optimum
brightness and/or maximum contrast following the frame mask
operation. The invention is further illustrated by the
following representative claim.
1. A method for imaging an area of investigation
comprising the steps of:
producing a source half-tone picture of an area of
investigation, said source half-tone picture
being composed of a plurality of individual picture
elements;
allocating respective source gray scale values to said
picture elements, said source gray scale values
corresponding to a morphology of said area of
