1. A method comprising:
at an electronic device including one or more processors, a non-transitory memory, and a see-through display:
determining first and second light superposition values that are associated with ambient light from a physical environment, wherein the first light superposition value quantifies the ambient light incident on a first region of the see-through display, and wherein the second light superposition value quantifies the ambient light incident on a second region of the see-through display, wherein the first region is adjacent to the second region;
modifying a first pixel value of image data, via a color correction function, in order to generate a corresponding first pixel value of display data, wherein the color correction function is based on a combination of the first and second light superposition values; and
displaying the corresponding first pixel value of the display data on the see-through display.
