Claim One:
1. A face clustering device comprising: a face detection unit for detecting a face included in an image; a face-direction detection unit for detecting a direction of the face detected by the face detection unit; a face identification unit for detecting, taking into account the direction of the face detected by the face-direction detection unit, a face with a similar feature and forming a collection of pieces of face information showing a feature of this face; a unit group setting unit for narrowing down, for each collection of pieces of face information formed by the face identification unit, the number of pieces of face information to a number set in advance for each face direction based on the direction of the face detected by the face-direction detection unit and setting each collection of pieces of face information for which the number has been narrowed down as a unit group; and a clustering unit for performing, with the unit group set by the unit group setting unit as a unit, clustering based on pieces of face information included in each unit group.
