ENCODING IMAGE DATA AT A HEAD MOUNTED DISPLAY DEVICE BASED ON POSE INFORMATION

摘要

An HMD device encodes different portions of an image for display with different encoding characteristics based on a user's predicted area of focus as indicated by one or more of a pose of the HMD device and a gaze direction of the user's eye(s) identified at the HMD device. By employing different encoding characteristics, the HMD device supports relatively high-quality encoding while maintaining a relatively small size of the encoded image to allow for transfer of the image to a display panel at a high frame rate. Thus, the HMD device can encode a portion of the image that is expected to be in the user's area of focus at a high resolution, and encode the portion of the image that is expected to be in the user's peripheral vision at a lower resolution.
