The white point of the rg chromaticity diagram is defined by the point (1/3,1/3). The white point has one third red, one third green and the final third blue. On an rg chromaticity diagram the first quadrant where all values of r and g are positive forms a right triangle. With max r equals 1 unit along the x and max g equals 1 unit along the y ...
A comparison between a typical normalized M cone's spectral sensitivity and the CIE 1931 luminosity function for a standard observer in photopic vision. 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 color space).
The primary colors are usually mapped to xyY chromaticity coordinates, though the uʹ,vʹ coordinates from the UCS chromaticity diagram may be used. Both xyY and uʹ,vʹ are derived from the CIE 1931 color space , a device independent space also known as XYZ which covers the full gamut of human-perceptible colors visible to the CIE 2° standard ...
Chromaticity is an objective specification of the quality of a color regardless of its luminance. Chromaticity consists of two independent parameters , often specified as hue ( h ) and colorfulness ( s ), where the latter is alternatively called saturation , chroma , intensity , [ 1 ] or excitation purity .
Moreover, the black point shall have the same chromaticity as the white point, yet with a luminance equal to 0.34731% of the white point luminance. [4] The ambient illumination level at the monitor faceplate when the monitor is turned off must be 32 lx. As with sRGB, the RGB component values in Adobe RGB (1998) are not proportional to the ...
The RG Chromaticity space is used in computer vision applications. It shows the color of light (red, yellow, green etc.), but not its intensity (dark, bright). The TSL color space (Tint, Saturation and Luminance) is used in face detection.
The rg chromaticity space is used in computer vision applications, and shows the color of light (red, yellow, green, etc.), but not its intensity (dark, bright). LMS color space (long, medium, short), a perceptual color space based on the response functions of the cones in the retina of the eye. It is mostly used in psychophysical research.
The background figure is the CIE xy chromaticity diagram. The choice of primary colors is related to the physiology of the human eye; good primaries are stimuli that maximize the difference between the responses of the cone cells of the human retina to light of different wavelengths, and that thereby make a large color triangle.
