Short Form of
CID Command
(Configure
Image Data)
The Short Form of the CID command involves sending just
the common 6-byte header. By changing the value of byte 0
(color space), the short form can specify the following five
color spaces:
Device RGB ?*v6W[0x00, . . . ]
Device CMY ?*v6W[0x01, . . . ]
CIE L*a*b* ?*v6W[0x03, . . . ]
The following data ranges are allowed in CIE L*a*b*. Hue
is preserved when out-of-range data is clipped.
L* = 0.0 to 100.0
a* = –100.0 to 100.0
b* = –100.0 to 100.0
Colorimetric RGB (SMPTE RGB) ?*v6W[0x02, . . . ]
Non-linear SMPTE RGB with a 2.2 gamma and 1.0 gain is
the default Colorimetric RGB color space. The short form
allows the following ranges:
R = 0.0 to 1.0
G = 0.0 to 1.0
B = 0.0 to 1.0
Luminance-Chrominance (YUV) ?*v6W[0x04, . . . ]
YUV, which is a linear transformation from SMPTE RGB,
is the default Luminance-Chrominance color space. The
short form allows the following ranges:
Y = 0.0 to 1.0
U = –0.89 to 0.89
V = –0.70 to 0.70
