The optical system comprises a display module for providing a visual overlay to be overlaid over an object in an augmented reality or mixed reality environment. The optical system comprises at least one sensor for sensing at least one optical property of the object. The optical system comprises a processing module configured to determine the at least one optical property of the object using the at least one sensor. The processing module is configured to determine a visual contrast between the visual overlay to be overlaid over the object and the object, as perceived within a field of view of the augmented reality or mixed reality environment, based on the at least one optical property of the object. The processing module is configured to selectively adjust an illumination of one of more portions of the field of view, or an optical attenuation of the one of more portions of the field of view, based on the determined visual contrast between the visual overlay to be overlaid over the object and the object."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical system and corresponding apparatus, method and computer program","description":"Examples relate to an optical system and to a corresponding apparatus, method and computer program.
