This paper presents a framework for developing a live vision-correcting
display (VCD) to address refractive visual aberrations without the need for
traditional vision correction devices like glasses or contact lenses,
particularly in scenarios where wearing them may be inconvenient. We achieve
this correction through deconvolution of the displayed image using a point
spread function (PSF) associated with the viewer's eye. We address ringing
artefacts using a masking technique applied to the prefiltered image. We also
enhance the display's contrast and reduce color distortion by operating in the
YUV/YCbCr color space, where deconvolution is performed solely on the luma
(brightness) channel. Finally, we introduce a technique to calculate a
real-time PSF that adapts based on the viewer's spherical coordinates relative
to the screen. This ensures that the PSF remains accurate and undistorted even
when the viewer observes the display from an angle relative to the screen
normal, thereby providing consistent visual correction regardless of the
viewing angle. The results of our display demonstrate significant improvements
in visual clarity, achieving a structural similarity index (SSIM) of 83.04%,
highlighting the effectiveness of our approach.
