Methods to improve the perceptual quality of foveated rendered images

A method comprising:

• rendering a foveated image that includes a foveated zone and a peripheral zone, wherein the foveated zone has a first set of image data and is rendered at a first pixel resolution and the peripheral zone has a second set of image data and is rendered at a second pixel resolution lower than the first pixel resolution;
• generating a control packet that includes rendering information associated with the foveated image;
• time warping the foveated image for movement in a viewer's position to form a time warped image;
• transmitting the time warped image and the control packet to a video processor;
• remapping the time warped image into a foveated region packed data block and a low resolution region packed data block;
• concatenating the control packet with the foveated region packed data block and the low resolution region packed data block to form a frame;
• transmitting the frame to a display unit;
• parsing the control packet from the frame;
• decoding the control packet to obtain the rendering information;
• and
• projecting a display image rendered according to the rendering information.
