1. Virtual chromaticity points at S-Gamut/
S-Gamut3
The virtual color space at S-GAMUT is shown in the above
chart. The virtual chromaticity points are as follows:
x y
R 0.73 0.28
G 0.14 0.855
B 0.1 –0.05
When converting the color space of a video source shot
with this camera in S-Gamut/S-Gamut3 mode, use these
virtual chromaticity points.
These chromaticity points are "virtual" because they do
not represent the actual, accurate color space but are the
calculated values for calculation of color space conversion.
These virtual chromaticity points have been introduced
because the actual color space cannot be represented as a
triangle in this colorimetry.
The following equation provides a simple conversion from
the color space for S-Gamut/S-Gamut3 to that for
conventional cameras (HDC-F950, HDW-F900R, etc.):

conventional cameras
Use the following equations to convert from S-Gamut/
S-Gamut3 to another color gamut.
