    • An image display device and a method therefor are provided to minimize power consumed in the image display device, prevent the degradation of image quality generated according to the reduction of power consumption, and secure the visibility of an image by changing the brightness and an image characteristic of the display device according to the strength of an external beam. An external beam detecting module(110) detects external illumination. A storing module(130) stores a light emitting unit control value capable of securing the visibility of an image according to the detected external illumination. A control module(120) determines whether it is possible to secure the visibility of the image by the light emitting unit control value inputted from a user from the detected external illumination by referring to the storing module(130), and selectively performs the brightness adjustment of a light emitting unit for an input image and the visibility adjustment of the image according to the determination.

    • PURPOSE: A color reproducing method and display device using the same are provided to adaptively control the color of an input image according to the illumination variation of a real use environment of a display device. CONSTITUTION: A display device converts source RGB data into first XYZ color space data(S1). The display device converts the first XYZ color space data into color space data for reflecting the brightness of a surrounding environment(S2). The display device inverses color space data into second XYZ color space data(S3). The display device inverses the second XYZ color space data to RGB data(S4). The display device selects modulation values according to the brightness of the surrounding environment(S5).
    • 目的:提供一种彩色再现方法和使用其的显示装置,以根据显示装置的实际使用环境的照明变化自适应地控制输入图像的颜色。 构成:显示设备将源RGB数据转换为第一XYZ色彩空间数据(S1)。 显示装置将第一XYZ色彩空间数据转换为颜色空间数据,以反映周围环境的亮度(S2)。 显示装置将颜色空间数据反转成第二XYZ色彩空间数据(S3)。 显示装置将第二XYZ色彩空间数据反转到RGB数据(S4)。 显示装置根据周围环境的亮度选择调制值(S5)。
