Abstract: Various implementations disclosed herein include devices, systems, and methods that present content items (e.g., movies, TV shows, home-made videos, etc.) on electronic devices such as HMDs. Some implementations adjust what is being displayed by the electronic devices to mitigate optical module-based artifacts (e.g., ghosting). For example, in an HMD with a catadioptric lens, a mirror layer may leak some light to produce ghosting artifacts that may be mitigated by adjusting brightness, dynamic range, contrast, light-spill, color, etc. Some implementations utilize adjustments that are based on content item awareness (e.g., adjustments based on the peak brightness of the scene in a movie that is being displayed within an extended reality (XR) environment, etc.). Some implementations provide adjustments based on environment awareness (e.g., how dark is the surroundings or pass-through environment) and/or optical module modeling. The adjustments may change a particular content item and/or an environment in which it is presented.

Abstract: Various implementations disclosed herein include devices, systems, and methods that adjust a tone map used to display virtual content in an extended reality (XR) environment based a tone map of pass-through video. For example, a process may obtain virtual content associated with a virtual content tone map relating pixel luminance values to display space luminance values. The process further obtains pass-through video depicting a physical environment. The pass-through video is associated with an image signal processing (ISP) tone map relating pixel luminance values of the pass-through video signal to display space luminance values. The process further determines an adjustment adjusting the virtual content tone map based on the ISP tone map. The process further displays a view of an XR environment. The view includes the pass-through video displayed using the ISP tone map and the virtual content displayed using the virtual content tone map with the adjustment.
