Synchronization circuitry for reducing latency associated with image passthrough

A method comprising:

• at a computing system including non-transitory memory and one or more processors, synchronization circuitry, and a content generation and delivery architecture including an image capture device, an image signal processing (ISP) pipeline, a partial frame buffer, a display pipeline, and a display device:
• 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 the synchronization circuitry, a synchronization signal for the content generation and delivery architecture based at least in part on the first reference rate, including generating a different synchronization signal for each portion of the content generation and delivery architecture based at least in part on the first reference rate and adjustable timing-related parameters associated with each portion of the content generation and delivery architecture;
• and
• operating the content generation and delivery architecture according to the synchronization signal and the temporal offset.

A non-transitory memory storing one or more programs, which, when executed by one or more processors of a computing system with synchronization circuitry and a content generation and delivery architecture including an image capture device, an image signal processing (ISP) pipeline, a partial frame buffer, a display pipeline, and a display device, cause the computing system to:

• determine 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, wherein the temporal offset includes one or more of a jitter delay and deterministic or non-deterministic temporal padding;
• obtain a first reference rate associated with a portion of the content generation and delivery architecture;
• generate, via the synchronization circuitry, a synchronization signal for the content generation and delivery architecture based at least in part on the first reference rate;
• and operate the content generation and delivery architecture according to the synchronization signal and the temporal offset.
