First Claim
1. An image processing apparatus comprising:
- a face detection unit configured to detect a face area of a person from an image;
a head detection area setting unit configured to set a head detection area based on the detected face area of the person;
an edge detection unit configured to detect an edge from the set head detection area, and generate an edge image which is comprised of the detected edge;
an edge deletion unit configured to delete an edge existing between the face and hair from the edge image; and
an ellipse detection unit configured to detect a candidate ellipse corresponding to a head area from an edge image from which an edge is deleted by said edge deletion unit.
