<p>An optical sensor for more accurate measurement, an optical sensing method, a program, and a recording medium. The optical sensor measures the luminance characteristic of a specific color outputted from a display illuminated with a specific illuminating light. Light separating means (60f) of the optical sensor separates the color component of the illuminating light from the color component of the specific color. A converting section (60g) for a display converts the separated color component of the specific color from LMS to XYZ by using an operand Md for the display. A converting section (60h) for illumination converts the separated color component of the illuminating light from LMS to XYZ by using an operand Mi for illumination. Thus, the conversion from RGB to LMS is carried out by independently using the operands for the display and illumination, and hence high-accuracy measurement can be made even for the superimposed colors of the output of the display and the illumination light.</p> |
