Method for determining the start of relaxation after a burn-in process at optical display devices controllable pixel by pixel

The invention relates to a method for determining a start of relaxation (t.sub.R) when switching over an optical display device (1) controllable pixel by pixel from a burn-in image (EB′) to a relaxation image (RB), wherein. A trigger image area (TB) having at least one image pixel is set to pixel values such that a parameter determined based on the at least one pixel value across the trigger image area (TB) differs between the burn-in image (EB′) and the relaxation image (RB). The local distribution of a greyscale value is continuously recorded by means of a camera (3, 13). A trigger subfield (20) comprising at least one sensor pixel (15) is defined matching the trigger image area (TB). A trigger parameter (T) is continuously determined from the pixel values of the at least one sensor pixel (15) in the trigger subfield (20) with a trigger clock rate and the start of relaxation (t.sub.R) is determined as the point in time at which the continuously determined trigger parameter (T) crosses the trigger threshold value (T.sub.S). The invention furthermore relates to a device and a method for determining the burn-in behavior of a display device (1) as well as the use of such a method for a display (1) determined for application in a vehicle.

Systems and methods for superimposing virtual image on real-time image

Disclosed are systems and methods for superimposing a virtual image on a real-time image. A system for superimposing a virtual image on a real-time image comprises a real-time image module and a virtual image module. The real-time image module comprises a magnification assembly to generate a real-time image of an object at a first location and a first depth, with a predetermined magnification. The virtual image module generates a virtual image by respectively projecting a right light signal to a viewer's right eye and a corresponding left light signal to a viewer's left eye. The right light signal and the corresponding left light signal are perceived by the viewer to display the virtual image at a second location and a second depth. The second depth is related to an angle between the right light signal and the corresponding left light signal projected to the viewer's eyes. The second depth may be approximately the same as the first depth.
