US Patent 9904056 Display

A display method using a display operable to display an image to a viewer is provided. The method includes detecting an initial position and/or orientation of an image view. Foreground portions of an image are rendered according to the detected initial position and/or orientation. Background portions of the image are rendered according to the detected initial position and/or orientation, at an image rendering rate. The following are performed at an image display rate higher than the image rendering rate: (i) detecting a current position and/or orientation of the image view; (ii) re-projecting the background portions of a most recent image according to any differences between the initial position and/or orientation and the current position and/or orientation of the image view; and (iii) combining the foreground portions and the re-projected background portions to generate an image for display.
