Abstract:
An electronic apparatus includes: 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, in a first state in which luminous intensity of the display is not less than a first threshold, in the case where the intensity of ambient light detected by the light sensor is less than predetermined intensity of light, outputs, to the display, a signal 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, and in the second state, outputs a signal to detect the intensity of ambient light to the light sensor.
