1. Virtual chromaticity points at S-GAMUT
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
in S-GAMUT mode, use
unit
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.
A simple formula for conversion from the color
space for S-GAMUT to that for conventional
cameras (HDC-F950, HDW-F900R, etc.) is
shown below:
Rw, Gw, Bw: RGB values for the original color
space for S-GAMUT
R, G, B: Values after being converted to the color
space for conventional cameras
2. Color space for film
The color space for film shown in the above chart
represents measurements from VISION Premier
Film EK 2393.
3. Color space for F900 mode
The color space for conventional cameras (HDC-
F950, HDW-F900R, etc.) is wider than that for
DCDM REF PJ but narrower than that for film.
