Abstract
Abstract An image evaluation apparatus and method capable of performing image evaluation more precisely using face information included in an image. An information obtaining unit obtains information with respect to at least one of the following face characteristics from an image including a face: face size, face position in the image, face orientation, face rotation angle, face-to-face positional relationship when a plurality of faces is included in the image, and face detection score. Then, an evaluation value calculation unit calculates an evaluation value representing an evaluation result of the image based on the information of the at least one of the face characteristics of face size, face position in the image, face orientation, face rotation angle, face-to-face positional relationship when a plurality of faces is included in the image, and face detection score obtained by the information obtaining unit.
