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
