Abstract: PURPOSE: A device and a method for generating a natural image of a digital television are provided to apply a matrix coefficient for generating a natural image to a chip set of color conversion, and then to correct an input image for colors of sky blue, flesh tone, etc., thereby factually approaching natural colors. CONSTITUTION: An input image converter(210) converts digital RGB(Red/Green/Blue) signals into a value of L*a*b. A natural color extractor(220) discriminates whether pixels of an input image have a natural color by using the converted L*a*b value. A matrix application unit(230) applies a matrix of a corresponding natural color to the input pixels discriminated to have the natural color in the natural color extractor(220). An output image generator(240) generates the image obtained through the matrix application unit(230) to have a new digital RGB value. The natural color extractor(220) calculates a hue value after converting the data inputted from the input image converter(210) into the L*a*b value in order to discriminate whether the calculated value belongs to a natural color.

Abstract: PURPOSE: A constant luminance controller of an HDTV and a method for generating and outputting constant luminance are provided to find a constant luminance value close to the color of the original image to produce images with high picture quality. CONSTITUTION: A constant luminance controller of an HDTV includes a luminance controller(1), a luminance comparator(104), and a signal converter(106). The luminance controller generates and stores a look-up table in which a predetermined constant luminance value of an image with high picture quality and a reference luminance value of a general image are contrasted with each other. The luminance comparator compares the reference luminance value with the luminance value of an input image. The signal converter extracts a constant luminance value corresponding to the reference luminance value when the luminance values compared with each other are similar to each other and converts the image into RGB signals using the extracted constant luminance value.

CONSTITUTION: An apparatus for extending linear color gamut of a color device includes an input color coordinate converter(210), a color gamut extension unit(220), a color gamut storage unit(230), and an output color coordinate converter(240). The input color coordinate converter receives red, green and blue color coordinates from a color device(100) with narrow color gamut to convert the color coordinates into color coordinates of luminance, chrominance and hue. The color gamut extension unit extends color attributes of luminance, chrominance and hue according to linear extension equation to convert the color attributes. The color gamut storage unit controls the color attribute information extended by the color gamut extension unit not to come out of a relatively wide color gamut device(300). The output color coordinate converter inverse-transforms the color attribute information into red, green and blue color coordinates to transmit the color coordinates to the wide color gamut device.

Abstract: PURPOSE: A system for selecting an experimental image of a display device and a method thereof are provided to select an experimental image having color areas which the display device is incapable of expressing, thereby affecting on algorithm development and judgement of the picture quality. CONSTITUTION: A display color gamut input unit receives information of RGB to L*a*b*(9*9*9) of a display device in a look-up table form. A display color gamut expanding unit expands RGB to L*a*b of (9*9*9) into RGB to L*a*b of (33*33*33) by using the three-dimensional interpolation. A display color gamut forming unit forms display color areas by forming 30*30*30 cells by dividing RGB to L*a*b of (33*33*33) by 30 equally. An experimental image converter converts an experimental image(RGB) into XYZ values for obtaining color gamut data, L*a*b. An experimental image verifying unit substitutes data of the experimental image for color gamut 30*30*30 cells in order for accumulating data not included in the cells and counting the number. According to the number of the accumulated pixels, the experimental image is selected.
