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 Imax    0≤C<0.001953
C' = C1/1.8 Imax    0.0019530≤C<1.0
C' = Imax    C≥1.0
    where Imax is the maximum integer value used for the nonlinear encoding
