*This abstract for appeared for patent application  number 18209643 Titled 'METHOD AND DEVICE FOR LATENCY REDUCTION OF AN IMAGE PROCESSING PIPELINE'

==Simplified Explanation==

The abstract describes a method for determining the complexity of an image of a physical environment and estimating the time it would take to combine virtual content with the image. If the estimated time exceeds a certain threshold, the method suggests not rendering the virtual content from the camera's perspective during that time period. Instead, it proposes using a previously rendered version of the virtual content and combining it with the image to create a graphical environment.


==Original Abstract Submitted==

In some implementations, a method includes: determining a complexity value for first image data associated with of a physical environment that corresponds to a first time period; determining an estimated composite setup time based on the complexity value for the first image data and virtual content for compositing with the first image data; in accordance with a determination that the estimated composite setup time exceeds the threshold time: forgoing rendering the virtual content from the perspective that corresponds to the camera pose of the device relative to the physical environment during the first time period; and compositing a previous render of the virtual content for a previous time period with the first image data to generate the graphical environment for the first time period.
