    Abstract: 본 발명은 보다 고정밀도의 측정이 가능한 광 검출 장치, 광 검출 방법, 프로그램 및 기록 매체를 제공하는 것을 과제로 한다.
    본 발명에 의한 광 검출 장치는, 특정의 조명광 아래에서 표시 장치가 출력하는 특정색의 휘도 특성을 측정한다. 본 발명에 의한 광 검출 장치에 의하면, 광 분리 수단(60f)에 의해서, 상기 조명광의 색성분과 상기 특정색의 색성분이 분리된다. 그리고, 표시 장치용 변환부(60g)에 의해서, 표시 장치용의 연산자(Md)를 이용하여, 상기 분리된 특정색의 색성분이 LMS에서 XYZ로 변환된다. 또한, 조명용 변환부(60h)에 의해서, 조명용의 연산자(Mi)를 이용하여, 상기 분리된 조명광의 색성분이 LMS에서 XYZ로 변환된다. 이와 같이, 표시 장치용의 연산자와 조명용 연산자를 독립적으로 이용하여 RGB에서 XYZ로의 변환을 행하기 때문에, 표시 장치의 출력과 조명광이 겹친 색에 대해서도 보다 고정밀도의 측정이 가능하게 된다.

    Abstract: PURPOSE: A method for color-displaying is provided to display color distribution by a colorimetric system, while taking adaptive color deviation of human eyes into account. CONSTITUTION: A reproduction medium displays one color under the control of the reproduction medium by using an output value, a monochrome locus of the color in the reproduction medium is measured and the measured value is stored, the processing step above is repeated by each output up to all the areas of the reproduction medium to store measured value pairs of the monochrome loci, the measured value pairs are converted into a color system, a white point of the reproduction medium is decided under a conversion origin, the converted value pair is stored in a calibration data-set, one converted value pair is assigned uniquely to each output value, the measured value of the luminous intensity distribution to be reproduced is converted into the color system used for the calibration of the reproduction medium, the proper conversion origin is selected by taking the adaptive color deviation of human eyes into account in a way such that the chromatic color visually perceived in the luminous intensity distribution to be reproduced is displayed as an achromatic color even by the reproduction medium, an output value (k) corresponding to each converted measured value pair in the luminous intensity distribution to be reproduced is selected from the calibration data-set for the reproduction medium and the luminous intensity distribution is displayed, by controlling the reproduction medium by using all output values obtained in the steps above.

    Abstract: PURPOSE: A method and an apparatus for detecting a temperature of an illumination color are provided to extract a stable and effective illumination information. CONSTITUTION: A method for detecting a temperature of an illumination color includes six steps. A first step is to select an image and find an RGB mean vector value as calculating a mean value by a channel of each RGB for the image. A second step is to define a predetermined coefficient f which is a larger positive number than 1 and estimate f times of the RGB mean vector value as a temporary illumination color for an image selected. A third step is to estimate the closest illumination color to a temporary estimation illumination color as an illumination color on a sunlight orbital. A fourth is to establish k times of an estimating illumination color as a self light emitting threshold value. The k is a predetermined coefficient and is a larger positive value than 1 A fifth step is to generate an image which a self light emitting area is removed as removing the self light emitting area having a larger RGB value than the self light emitting threshold value. A sixth step is to calculate and output an illumination color temperature from the UV chromaticity value of an image which the self light emitting area is removed.
