A driver state determination apparatus, a driver state determination method, and a recording medium. The driver state determination apparatus includes: a vehicle behavior information acquisition unitthat acquires behavior information of a vehicle; an image information acquisition unit that acquires image information including a face of a driver; a reference value setting unit that sets a reference value based on the behavior information of the vehicle acquired by the vehicle behavior information acquisition unit; and an index value calculation unit that calculates an index value relating to adriving state of the driver using duration of a state in which an amount of change in the image information acquired by the image information acquisition unit is equal to or less than the reference value. The apparatus further includes a determination unit that determines that the driver is in an unconscious state when the index value calculated by the index value calculation unit is equal to orgreater than a threshold value.

    驾驶员状态确定设备、驾驶员状态确定方法和记录介质。一种驾驶员状态确定设备包括:车辆行为信息获取单元,该车辆行为信息获取单元获取车辆的行为信息;图像信息获取单元,该图像信息获取单元获取包括驾驶员的面部的图像信息;参考值设置单元,该参考值设置单元基于由车辆行为信息获取单元获取的车辆的行为信息来设置参考值;以及指标值计算单元,该指标值计算单元使用由图像信息获取单元获取的图像信息中的变化量等于或小于参考值的状态的持续时间来计算与驾驶员的驾驶状态有关的指标值。所述驾驶员状态确定设备还包括确定单元,该确定单元在由指标值计算单元计算出的指标值等于或大于阈值时确定驾驶员处于无意识状态。
