The present invention relates to a monitoring device, monitoring method, control device, control method, and program that use information on a face direction or gaze direction of a person to cause a device to perform processing in accordance with a movement or status of the person. A target detector 251 detects a target object. A face direction/gaze direction detector 252 detects a face direction and gaze direction of a person, determines a movement or status of the person on the basis of the relationship between the detected target object and the face direction or gaze direction of the person, and notifies face direction/gaze direction information using portions 253-1 to 253-3 of a result of the determination. The face direction/gaze direction information using portions 253-1 to 253-3 cause the device to execute predetermined processing on the basis of the result of the determination. The present invention can be applied to, for example, an on-vehicle system.
