Patent ID: 8526683

Claim:
An image editing apparatus comprising: an image input unit including an image pickup circuit which takes a picture of a subject to obtain an image of a subject; a face detection circuit which detects an image of a face of the subject from the image obtained from the image input unit; a face expression detection circuit which detects a value indicating an extent of a smiling face of the subject as a face expression of the subject, based, at least in part, on (1) the image of the face detected by the face detection circuit, and (2) a sum of a normalized value of a whites of eyes area in the image of the face and a normalized value of a lips area in the image of the face; a pupil detection circuit which detects images of pupils of the subject, based on the image of the face detected by the face detection circuit; and a catch-light composition circuit which composes different catch-lights on the images of the pupils detected by the pupil detection circuit, according to any one of the direction and expression of the face detected by the face expression detection circuit, wherein the face expression detection circuit further determines if both (1) teeth are visible in the image of the face and (2) an end of mouth is shaded in the image of the face, and responsive to a determination that both (1) the teeth are visible and (2) the end of the mouth is shaded, increments the value by a predetermined amount, and otherwise, responsive to a determination that (1) the teeth are not visible or (2) the end of the mouth is not shaded, decrements the value by the predetermined amount.
