摘要： PURPOSE: A face image detection device is provided to set a light emission pattern in order to increase the light intensity of a projector, thereby reducing light flickering under high-intensity ambient light. CONSTITUTION: A projector(4) projects light on an area including a face of a passenger in a vehicle. An image photographing controller(24) sets up an image photographing condition for a photographing area which includes the face of the passenger. An image photographing part(5) photographs an image of the photographing area based on the image photographing condition. An ambient light detection part(3) detects ambient light which is irradiated to one of the vehicle and the passenger. An operation mode determination part(21) performs mode determination in order to determine an operation mode between two operation modes.
