Accurate driver state determination achieving safety is enabled without being affected by differences between individual drivers. A driver state determination apparatus for determining a driver state, such as distracted driving, includes a calculator that determines a direction of a vehicle driver's face or gaze based on first sensing data output from a first sensor and including an image of the driver, and calculates statistical information about a direction in which the driver looking straight ahead retains his or her gaze with respect to a forward direction of a vehicle. A correction unit corrects the determined face or gaze direction of the driver with respect to a reference direction defined as the forward direction of the vehicle based on the statistical information. A determiner determines a driver state based on a deviation of the corrected face or gaze direction of the driver from the reference direction.
