WebDunkirk Observer 1911-1915 - Chautauqua County, NY WebIt is possible to represent any color in terms of these primaries. They were derived so that equal values of X, Y, and Z produce white. They were arranged so that a single parameter Y determines the luminance of the color. They are related to the sensitivity of the human eye by the use of color matching functions which match to the C.I.E. 1931 ...

Thus the CIE 1931 Standard Observer function is also known as the CIE 1931 2° Standard Observer. A more modern but less-used alternative is the CIE 1964 10° Standard Observer, which is derived from the work of Stiles and Burch, and Speranskaya. For the 10° experiments, the observers were … See more The CIE 1931 color spaces are the first defined quantitative links between distributions of wavelengths in the electromagnetic visible spectrum, and physiologically perceived colors in human color vision. … See more In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ … See more Due to the distribution of cones in the eye, the tristimulus values depend on the observer's field of view. To eliminate this variable, the CIE … See more CIE RGB color space The CIE RGB color space is one of many RGB color spaces, distinguished by a particular set of monochromatic (single-wavelength) primary colors. In the 1920s, two independent experiments on … See more The human eye with normal vision has three kinds of cone cells that sense light, having peaks of spectral sensitivity in short ("S", 420 nm – 440 nm), middle ("M", 530 nm – 540 nm), and long ("L", 560 nm – 580 nm) wavelengths. These cone cells underlie human … See more Since the human eye has three types of color sensors that respond to different ranges of wavelengths, a full plot of all visible colors is a three-dimensional figure. However, the … See more A few other XYZ-style color-matching functions have been available. These functions imply their own XYZ-like and xyY-like color spaces. Judd and Vos … See more WebThe camera predictions are made by computing the resulting RGB values for the given camera’s sensitivity functions and then mapping them to the corresponding XYZ values based on a best linear fit of the camera sensitivity function to the CIE 1931 2°-observer x ¯, y ¯, z ¯ color matching functions. They measured the sensor sensitivity ...
WebJan 1, 2015 · Lines of equal tint run approximately parallel to the line of dominant wavelength 470 nm (467.6 and 464.7 nm, respectively, for the 1931 and 1964 CIE standard observers) in the chromaticity diagram. Figure 1 shows the line of dominant wavelength 470 nm and also two lines of iso-whiteness according to the CIE whiteness equation.
