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.
