Abstract
A system and method for increasing perceived contrast in a medical display is provided. The method involves temporarily increasing luminance output of at least part of a display in response to a received request for improved visualization. To compensate for the change in luminance especially while the viewer's eyes adapt to the change in luminance, the method includes continuously modifying the display parameters especially during an adaptation period to match an adaptation of the viewer's eyes. The modified parameters at any given may correlate to the degree of adaptation by the viewer's eyes to the change. After a period of time, the display may be returned to its normal operating luminance and corresponding settings, which may be selected to maximize the lifetime of the display.
