Information processing apparatus, processing method for the same, non-transitory computer-readable storage medium and image capturing apparatus

A processing method of an image processing apparatus, the processing method comprising:

• detecting a face of a person from an image;
• authenticating a person corresponding to the detected face, using information relating to the face in dictionary data which holds information relating to faces and line-of-sight correction data corresponding to respective persons;
• detecting information relating to a line of sight from the detected face;
• and
• correcting the information relating to the detected line of sight, using the line-of-sight correction data in the dictionary data corresponding to the authenticated person.

A non-transitory computer-readable storage medium storing a computer program that causes a computer to function as:

• a face detection unit configured to detect a face of a person from an image;
• a storage unit configured store dictionary data which holds information relating to faces and line-of-sight correction data corresponding to respective persons;
• an authentication unit configured to authenticate a person corresponding to the face detected by the face detection unit, using the information relating to faces in the dictionary data;
• a line-of-sight detection unit configured to detect information relating to a line of sight from the face detected by the face detection unit;
• and
• a line-of-sight correction unit configured to correct the information relating to a line of sight detected by the line-of-sight detection unit, using the line-of-sight correction data in the dictionary data corresponding to the person authenticated by the authentication unit.
