1. An electronic device, comprising:
an ambient light sensor configured to measure an ambient light condition;
control circuitry configured to:
apply a tone mapping and color compensation to an input image to produce a compensated image; and
compare a perceived version of the input image in a reference ambient light condition to a perceived version of the compensated image in the measured ambient light condition; and
a display configured to display the compensated image when a difference between the perceived version of the compensated image in the measured ambient light condition and the perceived version of the input image in the reference ambient light condition is less than a threshold.
