Claim of US Patent No. 10,134,321

1. A display device comprising:a display panel;
a driver configured to drive the display panel based on a video signal;
a detector configured to obtain a first detection value by detecting reflective light from a reflective media, which occurs when ambient light is irradiated to the reflective media, while obtaining a second detection value by detecting reflective light from the reflective media, which occurs when the display panel irradiates its display light to the reflective media; and
an acquisition part configured to acquire information concerning a color temperature of the ambient light based on a corrected drive value when the driver corrects the drive value for the display panel such that the second detection value approaches the first detection value or such that chromaticity represented by the second detection value approaches chromaticity represented by the first detection value.
