Image display device

An image display device comprising:

• an imaging unit configured to capture an image of a rear of a vehicle;
• a color temperature detection unit configured to detect a color temperature of a captured image captured by the imaging unit;
• a color temperature sensor installed at a front of the vehicle, the color temperature sensor being configured to detect a color temperature of incident light at the front of the vehicle;
• a white balance adjustment unit configured to perform adjustment of white balance of the captured image;
• a display unit configured to display the captured image adjusted by the white balance adjustment unit;
• an illuminance detection unit configured to detect a brightness of the captured image;
• an illuminance sensor installed at the front of the vehicle, the illuminance sensor being configured to detect a brightness of the incident light at the front of the vehicle;
• and
• an exposure control unit configured to control an exposure of the imaging unit, wherein
• when a difference between the color temperature of the captured image detected by the color temperature detection unit and the color temperature of the incident light detected by the color temperature sensor is a color temperature threshold value or greater, the white balance adjustment unit is configured to switch from a first white balance adjustment based on the color temperature of the captured image to a second white balance adjustment based on the color temperature of the incident light, and
• when a difference between the brightness of the captured image and the brightness of the incident light is a brightness threshold value or greater, the exposure control unit is configured to switch from a first exposure control based on the brightness of the captured image to a second exposure control based on the brightness of the incident light.
