Adaptive parameters in image regions based on eye tracking information

A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving eye tracking information comprising at least one image of an eye of a user viewing a screen of a display device;
• determining, based on the eye tracking information, a first screen region corresponding to a region of the screen, the first screen region containing a point of regard of the user, the point of regard representing a point on the screen at which the user is looking at the time the eye tracking information was captured;
• determining, based on the eye tracking information, a second screen region corresponding to a region of the screen that is separate from the first screen region;
• determining, based on the eye tracking information, a user's depth of focus,
• encoding an image for display on the screen, the image comprising an object with at least a portion of the object to be displayed within the first screen region, the encoding comprising:
• encoding a first image region of the image based on a first set of encoding parameters, the first image region comprising a portion of the image to be displayed in the first screen region,
• encoding a second image region of the image based on a second set of encoding parameters, the second image region separate from the first image region and to be displayed in the second screen region, the second set of encoding parameters resulting in a lower quality than the first set of encoding parameters, and
• responsive to a difference between a depth of the object in the image and the user's depth of focus exceeding a threshold value, encoding the object, including the portion to be displayed within the first screen region, with the second set of encoding parameters;
• and
• transmitting the encoded image to the display device to be displayed on the screen.
