IMAGE DISPLAY DEVICE

An image display device includes an imaging unit, a color temperature detection unit, a color temperature sensor, a white balance adjustment unit and a display unit. The imaging unit is configured to capture an image of a rear of a vehicle. The color temperature detection unit is configured to detect a color temperature of a captured image. The color temperature sensor is installed at a front of the vehicle to detect a color temperature of incident light. When a difference between the color temperature of the captured image and the color temperature of the incident light 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.
