Methods, devices, controllers and systems for color calibration of displays, non-volatile (non-transient) memory, controllers, display devices or display systems including a color calibration transform, operation of such controllers, display devices or systems and software for color calibration of a display are described are described that make use of a color transform having a distribution of color points across a full display gamut (hence optionally preserving full contrast and color saturation in the calibrated display) in an at least substantially perceptually uniform manner suitable for use as a color display calibration adapted for medical applications. A perceptually uniform spread of color points can be in terms of a distance metric such as deltaE2000 for color or JND for gray.

Perceptually optimised color calibration method and system

A system and method provide enhanced perceived contrast within a region of interest () 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 () outside of the ROI () 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 (). In addition, enhanced perceived contrast may also be achieved through a solution utilizing both hardware and software.
