Information processing apparatus and control method therefor

Abstract

An information processing apparatus includes an image input unit which inputs image data containing a face, a face position detection unit which detects, from the image data, the position of a specific part of the face, and a facial expression recognition unit which detects a feature point of the face from the image data on the basis of the detected position of the specific part and determines facial expression of the face on the basis of the detected feature point. The feature point is detected at a detection accuracy higher than detection of the position of the specific part. Detection of the position of the specific part is robust to a variation in the detection target.

What is claimed is: 
     
         1 . An information processing apparatus comprising:
 an input unit adapted to input image data containing a face;   a first detection unit adapted to detect, from the image data, a position of a specific part of the face;   a second detection unit adapted to detect a feature point of the face from the image data on the basis of the detected position of the specific part; and   a determination unit adapted to determine facial expression of the face on the basis of the detected feature point,   wherein said second detection unit has higher detection accuracy than detection accuracy of said first detection unit, and said first detection unit is robust to a variation in a detection target.
