1. A display driver, comprising:
interface circuitry configured to receive a full frame image and a foveal image from a source external to the display driver;
image processing circuitry configured to:
upscale the full frame image;
render a foveated image from the upscaled full frame image and the foveal image, wherein the foveated image comprises:
a foveal area based on the foveal image;
a peripheral area based on the upscaled full frame image; and
a border area based on the foveal image and the upscaled full frame image, the border area being located between the foveal area and the peripheral area; and
drive circuitry configured to drive a display panel using the foveated image.
