Checking Gamut
Checking RGB Gamut
The Diamond di
splay effectively shows
how the R, G, and B signals relate, making
it a good tool for detecting gamut errors.
The instrumen
t c onverts the Y, P
b,
and P
r
components recovered from the serial signal
to R, G, and B to form the Diamond display.
To predictab
ly display all three components,
they must lie between peak white, 700 mV,
and black, 0 V.
For a signal
to be in gamut, a ll signal vectors
must lie within the G-B and G-R diamonds.
Conversely, if a signal vector extends outside
the diamon
d, it is out of gamut. The direction
of an excursion out of gamut indicates
which signal is excessive. E rrors in green
amplitude
affect both diamonds equally,
while blue amplitude errors affect only the
top diamond and red errors affect only the
bottom di
amond.
