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: Generally, this disclosure provides methods and systems for real-time video communication with three dimensional perception image rendering through generated parallax effects based on identification, segmentation and tracking of foreground and background layers of an image. The system may include an image segmentation module configured to segment a current local video frame into a local foreground layer and a local background layer and to generate a local foreground mask based on an estimated boundary between the local foreground layer and the local background layer; a face tracking module configured to track a position of a local user's face; a background layer estimation module configured to estimate a remote background layer; and an image rendering module configured to render a 3D perception image based on the estimated remote background layer, the current remote video frame and the remote foreground mask.
