    Abstract: In one implementation, a method of warping an image is performed by a device including an image sensor, a display, one or more processors, and non-transitory memory. The method includes predicting a capture pose of the device in a physical environment at a capture time and a display pose of the device in the physical environment at a display time. The method includes capturing, using the image sensor, an image of the physical environment during a capture time period including the capture time. The method includes generating a warp definition based on the predicted capture pose and the predicted display pose. The method includes warping, using the one or more processors, the image of the physical environment based on the warp definition. The method includes displaying, on the display, the warped image of the physical environment during a display time period including the display time.

    Abstract: 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.

    Abstract: In some implementations, a method of reducing latency associated with an image read-out operation is performed at a device including one or more processors, non-transitory memory, an image processing architecture, and an image capture device. The method includes: obtaining first image data corresponding to a physical environment; reading a first slice of the first image data into an input buffer; performing processing operations on the first slice of the first image data to obtain a first portion of second image data; reading a second slice of the first image data into the input buffer; performing the image processing operations on the second slice of the first image data to obtain a second portion of the second image data; and generating an image frame of the physical environment based at least in part on the first and second portions of the second image data.
