ENCODING CHARACTERISTICS

Color space

Type: Colorimetric RGB color space

Color gamut: Extended

RGB primaries:

	x	y	z
R	0.7347	0.2653	0.0
G	0.1596	0.8404	0.0
B	0.0366	0.0001	0.9633

Color component transfer function:

C' = 0	C <0.0
C' = 16 C I_max	0≤C<0.001953
C' = C^1/1.8 I_max	0.0019530≤C<1.0
C' = I_max	C≥1.0

where I_max is the maximum integer value used for the nonlinear encoding
