The imaging part 10 takes an image of the face of a subject, and the face portion detection part 20 detects a reference face portion and a further face portion from the resulting image. The arrangement relation acquisition part 30 acquires the arrangement relation information of each face portion. The face portion tracking part 40 sets a reference face portion searching area for reference face portion tracking based on the information, and detects the position of the reference face portion from the reference face portion searching area. The tracking part 40 then sets a further face portion searching area for further face portion tracking to the taken image based on the position of the reference face portion and the arrangement relation information, and detects the position of the further face portion from the further face portion searching area. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
