<p>A photodetector capable of making a more accurate measurement, a photodetecting method, a program, and a storage medium, are to be provided. <??>The photodetector according to the present invention measures a luminance characteristic of a specific color outputted from a display unit under a specific illumination light. According to the photodetector of the present invention, color components of the illumination light and color components of the specific light are separated from each other by means of a light separator 60f. Then, using an operator Md for the display unit, the color components of the specific color thus separated are converted from LMS to XYZ by means of a converter 60g for the display unit. Further, using an operator Mi for illumination, the color components of the illumination light thus separated are converted from LMS to XYZ by means of a converter 60h for illumination. Thus, since the operator for the display unit and the operator for illumination are used each independently for the conversion from RGB to LMS, even a stacked color of both display unit output and illumination light can be measured with a higher accuracy. <IMAGE></p> |
