Facial expression is important and well-used clue to estimate emotion of a target person. However, in daily situation, facial expression captured in an image is often ambiguous and not reliable to estimate emotion behind it. In this report, we introduce a new approach to this issue that recognizes change in facial expression according to smiling. The proposed method compares two input images to estimate ascent or descent of smiling intensity. It achieved over 90\% recognition accuracy for facial expression changes during daily conversations. We also discuss availability of recognizing facial expression change for several applications and remained issues required to be solved for practical use.
