<P>PROBLEM TO BE SOLVED: To provide a face direction detector which detects the direction of the face based on a picked-up image of an imaging means. <P>SOLUTION: In a looking-aside monitor and alarm device applying the face direction detector, a centroid position G of an eye EO, a height H of the eye EO, and a width W of the eye EO of a full-faced face in an image picked up by the imaging means are defined as a reference centroid position G, a reference height H, and a reference width W respectively. and a vertical direction decision means compares a centroid position Gi and a height Hi of the eye in an image of the eye detected by an eye information detection means, with the reference centroid position G and the reference height H respectively to determine the vertical direction of the face, and a lateral direction decision means compares the centroid position Gi and a width Wi of the eye in the image of the eye detected by the eye information detection means, with the reference centroid position G and the reference width W respectively to determine the lateral direction of the face. <P>COPYRIGHT: (C)2004,JPO |
