Abstract
A control method for a display device includes: acquiring an output signal from a sensor detecting an illuminance in an environment where the display device is arranged; in a case where a first illuminance specified based on the output signal when a reference value of the illuminance in the environment is a first reference illuminance is higher than the first reference illuminance, changing the reference value from the first reference illuminance to a second reference illuminance that is higher than the first reference illuminance; and controlling a brightness of an image displayed on a display surface by the display device, based on a relationship between a second illuminance specified based on the output signal when the reference value is the second reference illuminance, and the second reference illuminance.
