Abstract
For a region of an image, a portion of a semi-reflective surface of an optical combiner from which light rays of the given region are reflected towards eyes of a user during display via a display unit is determined. For this portion of the semi-reflective surface, a secondary reflection intensity of light rays of another region of the image that undergo secondary reflection from a portion of another surface of the optical combiner is determined. A minimum intensity level of pixels in the image is increased. Intensity values of pixels in said region of the image are adjusted based on the secondary reflection intensity. The image is displayed via the display unit, thereby producing a synthetic light field. The optical combiner reflects the synthetic light field towards the eyes, whilst optically combining the synthetic light field with a real-world light field.
