A system and method provide enhanced perceived contrast within a region of interest (102) of an image being displayed in order to enable viewers to more easily perceive subtle features in images, such as during medical diagnostics. The enhanced perceived contrast may be implemented using software only, hardware only, or a combination of hardware and software. If the backlight of a display includes only one or few light sources, the enhanced perceived contrast can be achieved through a software only solution in which the area (104) outside of the ROI (102) is darkened. If the backlight of the display comprises, for example, an LED matrix, enhanced perceived contrast may be implemented through a hardware only solution in which the luminance of the display is increased in the ROI (102). In addition, enhanced perceived contrast may also be achieved through a solution utilizing both hardware and software.
