Electronic device

An electronic device which is capable of performing eye proximity sensing to sense contact of an eye with an eyepiece and line of sight detection to detect a line of sight, comprising:

• an eye proximity sensing sensor configured to receive light for the eye proximity sensing;
• a line of sight detection sensor configured to receive light for the line of sight detection, the line of sight detection sensor being separate from the eye proximity sensing sensor;
• one or more light sources including a light source used for both the eye proximity sensing and the line of sight detection;
• and
• a processor configured to control light-emission intensity of at least the light source used for the both, wherein
• in the eye proximity sensing, a state where a light receiving amount of the eye proximity sensing sensor exceeds a threshold value is sensed as the contact of the eye;
• and
• the processor controls the light-emission intensity after the contact of the eye is sensed by the eye proximity sensing, and controls the threshold value in accordance with the control of the light-emission intensity.
