olor Cube. sG's = round[4.500 X scG X 255] sB's = round[4.500 X scB X 255] scRGB if 4244 < (scR16, scG16, scB16) < 12288 The scRGB color space (formerly called sRGB64) sR's = round[(1.099 X scR0.45 0.099) X 255] extends the dynamic range, color gamut, and bit pre- sG'g = round[(1.099 X scG0.45 - 0.099) X 255] cision over sRGB. The scRGB gamut is not only much sB's = und[(1.099) X scB0.45 0.099) X 255] larger than the sRGB gamut, but it is larger than what the if (scR16, scG16, scB16) > 12289 human visual system can see. The specification for sR' g = 255 scRGB (IEC 61966-2-2) uses BT.709 chromaticity, D65 sG'g = 255 reference white, and linear RGB data (16 bits per color). sB's = 255 Instead of using a normalized range of 0-1, a range of -0.5 to +7.4999 is supported. Values below 0 and above 1 are what enable scRGB to have a larger gamut, YUV Color space compared to sRGB, even though it has the same primary colors. The correlation between the linear 16-bit scRGB The YUV color space is used by the PAL (Phase values and normalized range are: Alternation Line), NTSC (National Television System Committee), and SECAM (Sequentiel Couleur Avec 00000 = -0.5 Mémoire or Sequential Color with Memory) composite 04096 = 0.0 (black) color video standards. The black-and-white system used 12288 = 1.0 (white) only luma (Y) information; color information (U and V) 16384 = 1.5 was added in such a way that a black-and-white receiver 65535 = 7.4999 would still display a normal black-and-white picture. Color receivers decoded the additional color information After gamma correction, the correlation between the nonlinear 16-bit scR'G'B' values and normalized range are: to display a color picture. The basic equations to convert between gamma- 00000 = -0.7354 corrected RGB (notated as R'G'B') and YUV are: 04096 = 0.0 (black) Y = 0.299R' + 0.587G' + 0.114B 12288 = 1.0 (white) U = - 0.147R' - 0.289G' + 0.436B 65535 = 2.3876 = 0.492 (B' - Y) V = 0.615R' - 0.515G' - 0.100B' scRGB to sRGB Conversion = 0.877 (R' - Y) To convert linear 16-bit scR
