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: A head-mounted device (10) may include a camera (46) that captures a live video feed of an environment. A display (14) in the head-mounted device (10) may display passthrough display content that includes the live video feed. Control circuitry (20) may dynamically adjust a maximum allowable brightness for the passthrough display content during operation of the head-mounted device (10). Upon an initial donning of the head-mounted device (10), the passthrough display content may be permitted to use most or all of the achievable brightness range of the display (14). After a given time period, the user may be adapted to the brightness range of the display (14) and the maximum allowable brightness for the passthrough display content may be reduced to allow additional headroom for rendered display content. The control circuitry (20) 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.
