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.
