1. A method comprising, by a computing system:
determining an estimated distance of an eye of a user to a display plane of a display;
accessing, from a memory storage, a plurality of transmission maps characterizing non-uniform transmission characters of the display as measured from a plurality of pre-determined view positions within a measurement plane, the measurement plane being separated from the display plane by a known distance;
generating a custom transmission map for the estimated distance of the eye based on the plurality of transmission maps using light field rendering;
determining a custom correction map based on the custom transmission map;
adjusting an image to be displayed on the display using the custom correction map; and
displaying the image adjusted using the custom correction map on the display.
