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.

Abstract: PURPOSE: A device for correcting a lightness contrast of a video display apparatus according to brightness of ambient illumination is provided to compare information on an observation environment of the video display apparatus inputted by an observer through an RGB(Red/Green/Blue) sensor with a tag value included in a preset extended standard RGB color space, thereby providing high-quality video irrespective of observation environments. CONSTITUTION: A digital video file analyzer(302) receives a digital video file and divides the file into extended standard RGB video and luminescence-applied data information. The extended standard RGB video is divided into extended luminescence and extended chroma through an extended luminescence chroma transformer(304). The extended luminescence data of an extended luminescence unit(308) are inputted to a lightness contrast corrector(310). The lightness contrast corrector(310) performs lightness contrast correction for the extended luminescence data according to result data of a comparison/operation unit(326) to output the corrected data. An RGB sensor(320) senses ambient illumination to output an analog value. An analog-digital converter(322) converts the sensed analog value into a digital value to provide the converted value to the comparison/operation unit(326). The comparison/operation unit(326) compares the digital value with luminescence-applied data information included in a tag of the digital video file outputted by the digital video file analyzer(302) to output result data. The lightness contrast corrector(310) performs lightness contrast correction for the extended luminescence data according to the result data of the comparison/operation unit(326) to output the corrected data. The extended luminescence data passes through an extended luminescence operator(312) and is added to an extended chroma signal in an adder(314). Data in which the corrected extended luminescence signal and the extended chroma signal are added pass through an extended luminescence chroma inverse transformer(316) and are again transformed into signals of the extended standard RGB color space, and values of the converted signals are displayed through a video display apparatus for observers.
