1. An electronic apparatus comprising:
a display;
a light sensor located on an opposite side of a display surface of the display, and detects intensity of ambient light; and
a control unit which is configured to acquire a detection result indicating the intensity of ambient light detected by the light sensor, and to perform a luminance control process of controlling a luminous intensity of the display based on the acquired detection result,
wherein, in a case in which the display is in a first state in which luminous intensity of the display is not less than a first threshold and the detection result acquired by the control unit indicates that the intensity of ambient light detected by the light sensor while the display is in the first state is less than a predetermined intensity of light, the control unit is configured to (i) perform a first luminance reduction process of controlling the display to reduce the luminous intensity of the display to a second state that is not more than a second threshold that is less than the first threshold, (ii) newly acquire a detection result from the light sensor indicating the intensity of ambient light detected by the light sensor while the display is in the second state, (iii) after newly acquiring the detection result, end the first luminance reduction process and control the display to return to the first state, irrespective of the intensity of ambient light indicated in the newly acquired detection result, and (iv) after having controlled the display to return to the first state, perform the luminance control process to control the luminous intensity of the display based on the newly acquired detection result.
