    摘要： An image processing apparatus that detects a face area from image information includes a pattern database (110), a face-direction determining unit (105), and a face-area detector (106). The face-direction determining unit (105) determines, as a face direction, a direction in which a face image in image information is upright based on determination pattern information stored in the pattern database (110). The face-area detector (106) matches the direction of the image information with the direction of the determination pattern information based on the face direction, and detects a face area from the image information.
