摘要： PROBLEM TO BE SOLVED: To restrain colors of a plurality of color liquid crystal display from being seen as if the colors of the devices are not matched with one another. SOLUTION: Chromaticity is measured at each of a plurality of places including the reference place of the screen of a first color liquid crystal display (A), the average value of the measured chromaticity is calculated, a value obtained by correcting target chromaticity (xt, yt) with the chromaticity at the reference place and the difference of the average values is defined as new target chromaticity (xa, ya), and the first color liquid crystal displays (A) is calibrated so as to make the chromaticity at the reference place coincide with the corrected target chromaticity (xa, ya). The same adjustment is performed to a second color liquid crystal device (B). COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To drastically reduce the number of correction data stored for three-dimensional correction. SOLUTION: The image display device includes: a horizontal direction correction factor LUT (12) for storing and outputting a horizontal direction correction factor Kx corresponding to a horizontal position x; a vertical direction correction factor LUT (22) for storing and outputting a vertical direction correction factor Ky corresponding to a vertical position y; a gray level direction correction factor LUT (32) for storing and outputting a gray level direction correction factor Kp corresponding to a gamma-corrected gray level value P(z); a correction arithmetic operation unit (40) for performing correction to satisfy a three-dimensionally-corrected gray level value Q(x, y, z)=äKx(x)×Ky(y)×Kp(P(z))+1-Kp(P(z))}×(P(z)); and an image display unit (2) for displaying an image based on the three-dimensionally-corrected gray level value Q. Thus, circuit scale is reduced and adjustment man-hour for setting the correction data is drastically reduced. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To vary display image quality by only processing on a display device side according to the screen.
SOLUTION: A color picture/monochromatic picture deciding circuit 10 decides whether a picture includes a color picture or a monochromatic picture and a microprocessor 7 makes the display picture quality different by making the luminance, color temperature, and gamma characteristics different among: a case wherein it is decided that a color picture is included; a case wherein it is decided that a color picture is not included and a monochromatic picture is included; and a case wherein neither picture is included. Consequently, color picture display quality, suitable for display of a picture including an image obtained by taking a color picture of a natural thing, such as a flower, monochromatic picture display quality suitable for display of an X-ray image, and text display picture quality suitable for display of a text picture created in an editor, can be switched automatically.

摘要： PROBLEM TO BE SOLVED: To change a display brightness only by a processing on a display apparatus side in accordance with a screen to be displayed.
SOLUTION: When an image is displayed on the basis of color display signals d, a designated color discrimination circuit 10 discriminates whether colors in the whole display pixels constituting one screen include designated colors or not, and a microcomputer 7 changes brightness of a backlight 2 to change the display brightness depending on the discrimination result that an undesignated color is included or an undesignated color is not included. Therefore, by establishing rules that colors used in a screen-saver screen are regarded as designated colors and that the brightness is decreased when a picture does not contain a undesignated color, the display brightness of a screen-saver screen can be decreased to save electric power.

解决方案：当基于彩色显示信号d显示图像时，指定的颜色判别电路10判别构成一个屏幕的整个显示像素中的颜色是否包括指定的颜色，并且微计算机7改变亮度 背光2根据包含未指定颜色的判别结果或不包含未指定的颜色来改变显示亮度。 因此，通过建立将屏幕保护程序屏幕中使用的颜色视为指定颜色并且当图像不包含未指定颜色时亮度降低的规则，可以减少屏幕保护屏幕的显示亮度以节省电 功率。 版权所有（C）2006，JPO＆NCIPI
