Video camera optimizations based on environmental mapping

A head-mounted device (HMD) comprising:

• a motion sensor;
• a left-eye display;
• a right-eye display;
• one or more left-eye outward-facing cameras associated with a left-eye viewpoint;
• one or more right-eye outward-facing cameras associated with a right-eye viewpoint;
• a non-transitory computer-readable storage medium;
• and
• one or more processors coupled to the non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium comprises program instructions that, when executed on the one or more processors, cause the system to perform operations comprising:
• providing pass-through video via the HMD in which video captured via the one or more left-eye outward-facing cameras is presented on the left-eye display to provide an approximately live view of a physical environment from the left-eye viewpoint and video captured via the one or more right-eye outward-facing cameras is presented on the right-eye display to provide the approximately live view of the physical environment from the right-eye viewpoint;
• determining an environment characteristic corresponding to an appearance of flicker associated with one or more light sources of the physical environment;
• based on the environment characteristic, determining an exposure parameter of the pass-through video;
• and
• adjusting an exposure of the one or more left-eye outward-facing cameras and one or more right-eye outward-facing cameras based on the determined exposure parameter.

A non-transitory computer-readable storage medium, storing program instructions executable via one or more processors to perform operations comprising:

• providing pass-through video in which video captured via one or more left-eye outward-facing cameras is presented on the left-eye display to provide an approximately live view of a physical environment from the left-eye viewpoint and video captured via one or more right-eye outward-facing cameras is presented on the right-eye display to provide the approximately live view of the physical environment from the right-eye viewpoint;
• determining an environment characteristic corresponding to an appearance of flicker associated with one or more light sources of the physical environment;
• based on the environment characteristic, determining an exposure parameter of the pass-through video;
• and
• adjusting an exposure of the one or more left-eye outward-facing cameras and one or more right-eye outward-facing cameras based on the determined exposure parameter.
