Abstract: In some implementations, a method of synchronizing a content generation and delivery architecture to reduce the latency associated with image passthrough. The method includes: determining a temporal offset associated with the content generation and delivery architecture to reduce a photon-to-photon latency across the content generation and delivery architecture; obtaining a first reference rate associated with a portion of the content generation and delivery architecture; generating, via synchronization circuitry, a synchronization signal for the content generation and delivery architecture based at least in part on the first reference rate; and operating the content generation and delivery architecture according to the synchronization signal and the temporal offset.

Abstract: Generating synthesized data includes capturing one or more frames of a scene at a first frame rate by one or more cameras of a wearable device, determining body position parameters for the frames, and obtaining geometry data for the scene in accordance with the one or more frames. The frames, body position parameters, and geometry data are applied to a trained network which predicts one or more additional frames. With respect to virtual data, generating a synthesized frame includes determining current body position parameters in accordance with the one or more frames, predicting a future gaze position based on the current body position parameters, and rendering, at a first resolution, a gaze region of a frame in accordance with the future gaze position. A peripheral region is predicted for the frame at a second resolution, and the combined regions form a frame that is used to drive a display.
