- 摘要：
PROBLEM TO BE SOLVED: To provide a visual axis detecting device or the like, which removes a burden on a user and detects an accurate visual axis direction from the center of a pupil and the center of a corneal curvature.
SOLUTION: A visual axis controlling device includes: a camera 11 for imaging a direction of eye balls a plurality of light sources for emitting light to the direction of the eye balls a corneal curvature radius-calculating part 23 for calculating a corneal curvature radius based on a plurality of Purkinje images on a corneal surface acquired by the light emitted from the light source a part 24 for calculating the center of a corneal curvature, which calculates the center of the corneal curvature based on the corneal curvature radius, a position of the camera 11, and the position of the light source 12 a part 25 for calculating the center of a pupil, which extracts a pupil region based on the presence and absence of the reflection of the light emitted from the light source and calculates the center of the pupil by an ellipse approximation and a visual axis direction-determining part 26 for determining a vector passing through the center of the pupil and the center of the corneal curvature as the visual axis direction.
