Abstract
A display assembly includes a display console displaying at least one image on an image plane. The image is divided into a plurality of pixels. A controller is operatively connected to the display console and includes a processor and tangible, non-transitory memory on which is recorded instructions for executing a method for dynamically adjusting the image in real-time for off-axis viewing. The controller is programmed to generate a compensation-over-viewing-angle map which includes respective compensation factors for each of the plurality of pixels for multiple viewing positions. In one embodiment, the controller is programmed to apply separate respective compensation factors for the instantaneous viewing positions of a first user at a time j and a second user at a time k. In another embodiment, the controller is programmed to apply first and second compensation factors simultaneously at a time m, for a first image and a second image, respectively.
