Abstract: A head-mounted device may include a camera that captures a live video feed of an environment. A display in the head-mounted device may display passthrough display content that includes the live video feed. Control circuitry may dynamically adjust a maximum allowable brightness for the passthrough display content during operation of the head-mounted device. Upon an initial donning of the head-mounted device, the passthrough display content may be permitted to use most or all of the achievable brightness range of the display. After a given time period, the user may be adapted to the brightness range of the display and the maximum allowable brightness for the passthrough display content may be reduced to allow additional headroom for rendered display content. The control circuitry may continue to adjust tone mappings for passthrough display content and rendered display content based on whether the display content favors real-world content or virtual content.

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.

Abstract: Various implementations disclosed herein include devices, systems, and methods that adjust a brightness characteristic of virtual content (e.g., virtual objects) and/or real content (e.g., passthrough video) in views of an XR environment provided by a head mounted device (HMD). The brightness characteristic may be adjusted based on determining a viewing state (e.g., a user's eye perception/adaptation state). A viewing state, such as a user's eye perception/adaptation state while viewing a view of an XR environment via an HMD, may respond to a brightness characteristic of the XR environment that the user is seeing, which is not necessarily the brightness characteristic of the physical environment upon which the view is wholly or partially based.

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.
