1. An electronic device, comprising:
a display comprising pixels;
a sensor comprising a light emitter that emits light through the display; and
control circuitry configured to:
based on a first set of operating conditions for a first display frame and a second set of operating conditions for a second display frame, determine a first optimal firing time for the light emitter in the sensor, wherein the first optimal firing time is a delay relative to the beginning of the first display frame and wherein the second display frame is previous to the first display frame;
based on the second set of operating conditions for the second display frame, determine a second optimal firing time for the light emitter in the sensor, wherein the second optimal firing time is a delay relative to the beginning of the second display frame and the second optimal firing time is different from the first optimal firing time; and
control the light emitter to emit light at the first and second optimal firing times, respectively, during the first and second display frames.
