Display device and display method

Abstract

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