US 11,887,550 B2 · Viewing-angle-dependent color/brightness correction for display system

Abstract

A display system including a tracking subsystem configured to track one of a pose of a head of a viewer or a pose of an eye of the viewer. The display system further includes an image correction module configured to, for each pixel of at least a subset of pixels of an input image, determine a pixel view angle for the pixel based on the pose of the head or the pose of the eye, determine a corrected pixel value based on an input pixel value of the pixel in the input image and based on the pixel view angle; and provide the corrected pixel value for the pixel in an angle-corrected image corresponding to the input image. The display system further includes a display panel to display the angle-corrected image.

Dependent claims

A display system comprising:

a tracking subsystem configured to track at least one of a pose of a head or a pose of an eye of a viewer;
an image correction module configured to:
for each pixel of at least a subset of pixels of an input image:
determine a pixel view angle for the pixel based on the pose of the head or the pose of the eye;
determine a corrected pixel value based on an input pixel value of the pixel in the input image and based on the pixel view angle;
and
provide the corrected pixel value for the pixel in an angle-corrected image corresponding to the input image;
and
apply at least one of a spatial dithering pattern or a temporal dithering pattern to corrected pixel values of the angle-corrected image;
and
a display panel to display the angle-corrected image.
