Abstract
It is possible to accurately detect a face center position based on an image of a person when the person is wearing glasses even when the person is facing sideways. Face images obtained as a result of photographing a face of a driver using a camera (10) are stored in an image memory (22). The CPU 24 determines positions of the sides and top and bottom positions of the face based on the face images stored in the image memory (22). Further, the CPU 24 determines whether or not the driver is wearing glasses or is facing sideways. When the wearing glasses and facing sideways is determined, a face center position is detected using face images for a lower region of the face. As a result, it is possible to detect a face center position in a reliable manner even when a driver wearing glasses is facing sideways.
