ABSTRACT:
To detect faces contained in an image with changing position, inclination and orientation of a face to be detected, an indicator value for each position, inclination and orientation is calculated, which indicates probability of a partial image at the position being a face image having the inclination and the orientation. Then, the partial images having the indicator values not less than a first threshold are extracted as candidates. When a predetermined evaluation value indicating reliability of a certain candidate having a predetermined inclination and a first orientation is not less than a predetermined threshold value, another candidate having the predetermined inclination and a second orientation is discriminated as being a true face. When the candidates having the indicator values not less than a second threshold are discriminated as being true faces, the second threshold is lowered for another candidate having the predetermined inclination and a second orientation for discrimination.
