Abstract: The display device has a sensor system with at least one sensor for detecting the intensity or colour of light emitted from at least one display area of the display device into the viewing angle of the display device. The sensor system further has in one embodiment an at least partially transparent sensor. The sensor system has in another embodiment at least one optical coupling device including a light guide member and a incoupling member for guiding or directing, e.g. deflecting, reflecting, bending, scattering, diffracting, at least one part of the light emitted from the display area to the corresponding sensor, where the sensor is located outside or at least partially outside the viewing angle of the display device.

Abstract: An image processing method and system are described for processing medical images. The method comprises using a new coordinate system for representing combined image data of said plurality of medical images based on correlation information between image data of a plurality of medical images. The method further may comprise extracting such correlation information, and after said representing, mapping obtained image data to an antagonist colour space, thus resulting in visualisation with a fused image with high contrast and luminance and with particular human vision parameters relating to equalities and differences in the plurality of medical images studied.
