Method for reducing subjective visual artefact in binocular display
A recently granted patent (Publication Number: US11989856B2) outlines a method and system for reducing subjective binocular rivalry artifacts when displaying binocular overlapping images to users of a binocular display system. The method involves generating right and left-eye source images with multiple information layers, projecting these images to users, and modifying pixel and image parameters to reduce the perception of rivalry artifacts. The system includes an image display unit, binocular viewing optics, and a display unit control engine that adjusts parameters based on the association of objects with different information layers, prioritizing correction for background scenes over symbology layers.
Furthermore, the patent details the determination of border area locations between overlapping and non-overlapping regions of observed images to identify artifact boundaries. The system's display unit control engine can modify pixel and image parameters to reduce rivalry artifacts in monocular viewing regions, ensuring adjustments do not exceed Just Noticeable Differences. The system's performance characteristics influence the correction process, with a focus on reducing artifacts in specific regions. The system's components include a processor, memory, and circuitry for implementing the display unit control engine, enabling efficient artifact correction for improved user experience.
