• and
• a first electronic control unit (ECU) configured to perform image processing so as to provide the extended function on the basis of driving information acquired in relation to driving of a vehicle and first image information photographed through the first photographing part or provide an existing function by receiving, from an external system, information for performing the existing function which is performed by the external system including a second ECU,
• wherein:
• the first photographing part includes a red, green, blue (RGB) camera and an infrared camera;
• and
• when an amount of ambient light of the vehicle is less than or equal to a predetermined amount of light, the first ECU determines to display the first image information including at least partial infrared image information photographed through the infrared camera and when the amount of ambient light of the vehicle is greater than the predetermined amount of light, the first ECU determines to display the first image information including RGB image information photographed through the RGB camera.
