Abstract: An eye direction detecting apparatus includes a display unit, an imaging unit, a first detecting unit, a second detecting unit, and a display control unit. The imaging unit captures a subject. The first detecting unit detects a position of an eye of the subject from an image captured by the imaging unit. The second detecting unit detects a distance from the imaging unit to the position of the eye of the subject. The display control unit displays the image indicating the position of the eye of the subject on the display unit with a display manner being changed according to the distance detected by the second detecting unit.
