Shot groups that include face areas and satisfy a predetermined criterion are selected out of shot groups that are sets of similar shots. Face areas included in the same shot group are classified according to features. A classified face area group included in the same shot group is presumed to be that of the same person and selected as the face area group of a main character. Consequently, the main character is selected by combining similarity of shots forming a picture and face area detection. Therefore, even in a picture including a character whose face cannot be detected in a part of shot sections, it is possible to order and select characters and select a face of a main character more conforming to actual program contents in a television program than that in the related art.
