Abstract
A driver monitor detects, based on face images obtained by capturing the face of a driver of a vehicle at different times, a color of the face of the driver and a face orientation angle of the driver in each face image; stores, when a face orientation angle detected from a first face image captured at a first time is included in a predetermined range of face orientation angles, the color detected from the first face image in a memory; and determines that the color of the face is abnormal, when a face orientation angle detected from a second face image captured at a second time later than the first time is included in the range of face orientation angles and a difference between the color detected from the second face image and the color stored in the memory exceeds a variance threshold.
