In this passenger status determination device (10), a vehicle interior image acquisition unit (11) acquires a vehicle interior image in which the vehicle interior is captured. A faulty-image determination unit (12) determines, for each frame, whether the vehicle interior image is suited for detecting the face of a passenger, and determines that a vehicle interior image determined to not be suited for detecting the face of a passenger is a faulty image. A passenger status determination unit (13) determines the status of the passenger on the basis of the vehicle interior images for each of the frames, accumulates the results of said determination, and finally determines the status of the passenger on the basis of the results of determining the status of the passenger that were accumulated over a given period. A control unit (14) causes the passenger status determination unit (13) to not implement the determination of the status of the passenger based on vehicle interior images determined to be faulty images or to not implement the accumulation of the results of determining the status of the passenger based on the vehicle interior images determined to be faulty, and furthermore, when the proportion of vehicle interior images determined to be faulty images within the given period exceeds a predetermined threshold value, the control unit (14) causes the passenger status determination unit (13) to delete the results of determining the status of the passenger that were accumulated until the time of deletion.
