<P>PROBLEM TO BE SOLVED: To accurately detect a vertical direction of a face of each of plural drivers. <P>SOLUTION: A face direction detector 10 comprises an acquisition part 24, a calculation part 25, a determination part 27, and a detection part 28. Based on each of a plural pieces of image data including a driver face acquired by the acquisition part 24, the calculation part 25 calculates a feature amount of the driver face for each image. Based on commonality of the plurality of feature amounts calculated by the calculation part 25, the determination part 27 determines a reference value corresponding to the driver. When detecting a vertical direction of the driver face, the detection part 28 performs the following processing. That is, when detecting the direction, based on the feature amounts of the driver face calculated by the calculation part 25 based on the image data acquired by the acquisition part 24, and the reference value corresponding to the driver, the detection part 28 detects the vertical direction of the driver face. <P>COPYRIGHT: (C)2012,JPO&INPIT |
