1768058-A2 is referenced by 39 patents.

An information processing apparatus includes an image input unit (100) which inputs image data containing a face, a face position detection unit (101) which detects, from the image data, the position of a specific part of the face, and a facial expression recognition unit (102) 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.
