1. A method for reducing a subjective binocular rivalry artefact when displaying binocular overlapping images to a user of a binocular display system, the method comprising:
generating, by an image display unit comprising a plurality of pixels elements relating to a plurality of different information layers, right and left eye source images;
projecting the right and left-eye source images via corresponding left and right viewing optics to its user such that the user perceives partially overlapping left and right-hand observation images;
reducing a perception of binocular rivalry artefact in a subjective artefact region in the perceived right and/or left-hand observation images by modifying one or more pixel parameter values of one or more pixels and/or by modifying one or more image parameters values of one or more display regions relating to the left and/or right-hand source images,
wherein the modifying of one or more pixel parameter values is performed based on an association of a displayed object with at least two of the plurality of different image information layers,
wherein at least one first information layer pertains to a scene and at least one second information layer pertains to symbology overlaying the scene, and
wherein binocular rivalry artefact correction is performed to a greater extent for the least one first information layer pertaining to the scene than for the at least one second information layer pertaining to the symbology.
