A DISPLAY SYSTEM AND METHOD FOR CONTROLLING A DISPLAY

摘要

A processing unit (24) is configured to receive a polychromic image input (16) and determine at least one primary range of intensities for representing the primary image and at least one secondary range of intensities for representing symbology. The primary range(s) do not overlap with the secondary range(s) so that a viewer can view the primary image in the primary range and the symbology in the secondary range. The processing unit (24) outputs to the display (12) a monochromatic image output (26) in which the primary image is represented by intensities in said at least one primary range and the symbology is represented by intensities in said at least one secondary range.
