1. A display driver, comprising:
image processing circuitry configured to:
receive a foveal image, a full frame image, and coordinate data that specifies a position of the foveal image in the full frame image; and
render, after receiving the foveal image, the full frame image, and the coordinate data, a resulting image based on the full frame image independently of the foveal image in response to detection of a data error within the coordinate data, wherein rendering the resulting image based on the full frame image independently of the foveal image is performed without referring to the foveal image; and
drive circuitry configured to drive a display panel based on the resulting image.
