<p>An illuminance change detector obtains detected illuminance values from a plurality of illuminance detectors, and determines whether the illuminance value detected by each illuminance detector changed from an illuminance range to another illuminance range. When the illuminance value detected by at least one of the plurality of illuminance detectors changed from the illuminance range to the other illuminance range, an image quality control unit sets different timing to change an image quality adjustment value for a display image from an image quality adjustment value corresponding to the illuminance range to an image quality adjustment value corresponding to the other illuminance range, depending on how many of the illuminance values detected by the illuminance detectors changed from the illuminance range to the other illuminance range.</p> |
