PROBLEM TO BE SOLVED: To easily add a function for changing setting for determining inattentive driving.SOLUTION: The face of a driver is successively photographed to acquire a photographic image, and then the direction of the face of the driver is detected by using the acquired photographic image. Then, whether or not the detected direction of the face is beyond a preliminarily set inattentive driving normal determination range is determined, and when it is determined that the direction of the face is beyond the inattentive driving normal determination range, a voice indicating that the driver is inattentively driving is output with a preliminarily set volume. Furthermore, when the hand of the driver is projected in the acquired photographic image (S120: YES), the shape of the hand of the driver is detected by using the photographic image acquired by a camera 3 (S140), and the volume of a voice output part 5 is set on the basis of the shape of the hand of the driver (S150), and the inattentive driving normal determination range is set on the basis of the detected direction of the face (S160). |
