- FIG. 2 is a diagram illustrating an AR application.
- FIG. 7A shows an enlarged view of the left eye of the subject 92 detected from the captured image I captured by the camera 84.
- the distance dp between the center of the pupil P and the inner corner of the eye Q changes according to the line-of-sight direction. Specifically, as shown in FIG. 7A, when the line of sight turns to the left (toward the outer corner S side of the eye), the distance dp increases. On the other hand, when the line of sight turns to the right (toward the inner Q side of the eye), the distance dp becomes smaller. Therefore, when the distance dp is measured, the approximate line-of-sight direction can be calculated.

Specifically, as shown in FIG. 7B, when the line of sight turns to the left (toward the outer corner S side of the eye), the pupil P is located on the outer corner S side of the corneal reflex image R. On the other hand, when the line of sight is directed to the right (facing the inner corner Q side of the eye), the pupil P is located closer to the inner corner Q side of the corneal reflex image R. Therefore, when the positional relationship between the pupil P and the corneal reflex image R is measured, an approximate line-of-sight direction can be detected.
