Abstract
A computing system may determine, for a current frame, a viewer's current eye position with respect to a waveguide of a display, identify eye positions that collectively form a grid of eye positions surrounding the current eye position, obtain, from a memory on the display, compressed arrays of scaling factors for correcting non-uniformities of the waveguide at the identified eye positions, perform interpolation based on the compressed arrays to generate an array of scaling factors for the current eye position, adjust pixel values of the current frame based on the customized array, and output the current frame with the adjusted pixel values to the display. The compression operation may include dithering or converting pixel values to a different color space. The interpolation may be performed on the compressed arrays or on results of a decompression operation. The customized array may be up-sampled prior to adjusting the pixel values.
