1. A heads mounted display (HMD) device, comprising:
a display, configured to display a pre-warp image;
an optical system, configured to receive the pre-warp image and output an undistorted image; and
a processor, configured to:
generate an original image, wherein the original image comprises a regular grid of regions of pixels;
perform a tolerance enhancement operation on the original image to generate an enhanced image; and
apply a software distortion on the enhanced image to generate the pre-warp image, wherein the software distortion is configured to compensate an optical distortion of the optical system.
