Rec. 2020 defines a bit depth of either 10 bits per sample or 12 bits per sample. [2] 10 bits per sample Rec. 2020 uses video levels where the black level is defined as code 64 and the nominal peak is defined as code 940. Codes 0–3 and 1,020–1,023 are used for the timing reference.
This is exactly 5 times the color resolution of 8-bit sRGB, and 8-bit sRGB can be converted directly with 5x + 1024. The linear range is clamped to the slightly larger −0.6038..7.5913 . A 12-bit encoding called scYCC-nl is the conversion of the non-linear sRGB levels to JFIF-Y'CbCr and then converted by 1280 Y ′ + 1024 , 1280 Cb + 2048 ...
CIE 1931 xy chromaticity diagram showing the gamut of the wide-gamut RGB color space and location of the primaries. The D50 white point is shown in the center. The wide-gamut RGB color space (or Adobe Wide Gamut RGB) is a color space developed by Adobe Systems, that offers a large gamut by using pure spectral primary colors. [1]
It follows that in limited range 8-bit R'G'B' the color black is represented as (16,16,16) while white is (235, 235, 235). In 8-bit Y'C' B C' R , black is (16, 128, 128) and white is (235, 128, 128). Quantized color coordinates outside the nominal ranges above are allowed, but typically they would be clamped for broadcast or for display (except ...
Rec. 2100 is a technical recommendation by ITU-R for production and distribution of HDR content using 1080p or UHD resolution, 10-bit or 12-bit color, HLG or PQ transfer functions, full or limited range, the Rec. 2020 wide color gamut and YC B C R or IC T C P as color space.
DCI-P3 covers 53.6% [4] of the CIE 1931 chromaticity diagram (see inset image), which describes the color gamut of human color vision. A smaller, practical gamut for comparison is the Pointer's gamut, which consists of diffusely reflecting surface colors. DCI-P3 covers 86.9% of Pointer's gamut, [5] while in comparison, Rec. 709/sRGB only covers ...
In color reproduction and colorimetry, a gamut, or color gamut / ˈ ɡ æ m ə t /, is a convex set containing the colors that can be accurately represented, i.e. reproduced by an output device (e.g. printer or display) or measured by an input device (e.g. camera or visual system). Devices with a larger gamut can represent more colors.
This is a list of software palettes used by computers. Systems that use a 4-bit or 8-bit pixel depth can display up to 16 or 256 colors simultaneously. Many personal computers in the early 1990s displayed at most 256 different colors, freely selected by software (either by the user or by a program) from their wider hardware's RGB color palette.
