PARKING AREA DETERMINATION DEVICE, VEHICLE CONTROL DEVICE, PARKING AREA DETERMINATION METHOD, AND PROGRAM

To recognize whether a vehicle is located within a parking area even when an imaging device is not activated, a parking area determination device is provided. The device includes an acquisition unit configured to detect, based on image data acquired by the imaging device that captures surroundings of a vehicle, parking spaces and/or parked vehicles, and to acquire parking rows in which the detected parking spaces and/or parked vehicles are adjacent in a predetermined direction and appear continuously in at least a predetermined number. A determination unit determines whether the vehicle is located within a parking area. After determining that the vehicle is in the parking area, when a start switch is turned off and then turned on while the imaging device is not yet activated, the unit determines the vehicle remains in the parking area while a travel distance and vehicle speed are below respective thresholds.
