Methods to improve the perceptual quality of foveated rendered images

A method of generating foveated rendering for a display, the method comprising:

• generating a first spatial profile for a field of view (FOV) of the display by dividing the FOV into a first foveated zone and a first peripheral zone, the first foveated zone including first pixels rendered at a first pixel resolution, and the first peripheral zone including second pixels rendered at a second pixel resolution lower than the first pixel resolution, wherein the first foveated zone includes a first region including a subset of the first pixels and a second region including a remainder of the first pixels;
• generating a second spatial profile for the FOV of the display by dividing the FOV into a second foveated zone and a second peripheral zone, the second foveated zone being spatially offset from the first foveated zone, the second foveated zone including third pixels rendered at the first pixel resolution, and the second peripheral zone including fourth pixels rendered at the second pixel resolution, wherein the second foveated zone includes a third region including a subset of the third pixels and a fourth region including a remainder of the third pixels;
• and
• multiplexing the first spatial profile and the second spatial profile for a left eye and a right eye of a viewer viewing the display, respectively, so that the viewer perceives images rendered in the first region of the first foveated zone that does not overlap with the second foveated zone and/or in the third region of the second foveated zone that does not overlap with the first foveated zone.
