Adaptive exposure

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 HMD 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 a 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 live view of the physical environment from the right-eye viewpoint;
• detecting a current motion corresponding to a current rotation of the HMD during the capture of multiple frames by the one or more cameras in a physical environment, wherein the current rotation is detected using an inertial measurement unit or a gyroscope;
• predicting a continued rotation of the device for one or more next frames after the multiple frames based on the current rotation;
• determining an exposure parameter to limit the appearance of blur that would result from the continued rotation of the HMD, wherein the exposure parameter is a maximum exposure time resulting in a predetermined level of blur on an image sensor;
• adjusting an exposure of the one or more left-eye outward facing cameras and the one or more right-eye outward facing cameras to provide the pass-through video comprising the one or more next frames based on the determined exposure parameter;
• and
• presenting the video on the display of the HMD.

A non-transitory computer-readable storage medium, storing program instructions computer-executable on a computer to perform operations comprising:

• detecting a current motion corresponding to a current rotation of the HMD during the capture of multiple frames by the one or more cameras in a physical environment, wherein the current rotation is detected using an inertial measurement unit or a gyroscope;
• predicting a continued rotation of the device for one or more next frames after the multiple frames based on the current rotation;
• determining an exposure parameter to limit the appearance of blur that would result from the continued rotation of the HMD, wherein the exposure parameter is a maximum exposure time resulting in a predetermined level of blur on an image sensor;
• adjusting an exposure of one or more cameras based on the determined exposure parameter;
• capturing video comprising the one or more next frames of the physical environment via the one or more cameras of the HMD according to the adjusted exposure;
• and
• presenting a view on the one or more displays of the HMD based on the captured video, the view providing a viewpoint of the physical environment.
