Abstract: Systems and techniques are provided for synchronizing a frame rate of pass-through content from a camera and a display refresh rate. An example method can include obtaining first and second frames captured by an image capture device (which may be part of a device, such as an extended reality (XR) device). A display refresh rate of a display is greater than a camera frame rate of the image capture device. The method may determine motion between the first frame and the second frame. The method can include predicting, based on the second frame and the determined motion, a third frame corresponding to a time after the second frame. The method can include displaying content (e.g., mixed reality content) including the predicted third frame and virtual content rendered for the XR device.

Abstract: Example techniques are described for generating graphics content by obtaining a rendering command for a first frame of the graphics content, rendering a full frame based on the rendering command for the first frame, storing the full frame in a buffer, obtaining a rendering command for a second frame of the graphics content, obtaining an eye position of a user, rendering a partial frame based on the rendering command for the second frame and the eye position of the user, obtaining the full frame from the buffer, and outputting the second frame, wherein the second frame is based on the full frame and the partial frame.

Abstract: This disclosure proposes utilizing user movement and virtual object movements to correct a displayed frame in a field-sequential display in a display system. Temporal delay of each color channel is corrected by re-sampling rendered frames before display so each color channel is offset appropriately based on the motion of the rendered content and/or the motion of the user. The correction can be applied during a timewarp rendering pass. A user's physical movement can be corrected using the user's change in pose/position to apply a color channel correction to the entire rendered frame. In-frame content movement can be corrected using the motion of the rendered content to apply focused color channel correction to targeted regions of the rendered frame.
