A first filter transmits a portion of incident light that has a first dominant wavelength. A second filter transmits a portion of incident light that has a second dominant wavelength different from the first dominant wavelength. An illuminance detector detects a first illuminance of light transmitted through a first filter and a second illuminance of light transmitted through a second filter. A controller adjusts the luminance of an image display on a display device according to the first illuminance and the second illuminance detected by the illuminance detector.
