RGB
This is a definition of the practical RGB color space proposed by Adobe Systems in 1998. The
color reproduction range (color gamut) is broader than sRGB, and is highly adaptable to such fields
as printing etc.
Color Space
YUV and RGB, etc. are available. YUV expresses the color by using the luminance (Y), the color
difference of Blue (U), and the color difference of Red (V).
RGB does this by using the gradation of the 3 colors, Red (R), Green (G), and Blue (B).
DCI (Digital Cinema Initiatives)
The company was founded by an association of U.S. film studios, and this company decides the
specifications for digital cinema.
DisplayPort
This is the interface standard for image signals standardized in accordance with VESA. It was
developed with the aim of replacing the conventional DVI and analog interfaces, and it can transmit
high resolution signals and sound signals, which DVI does not support. The standard size and mini
size connectors have been standardized.
DVI (Digital Visual Interface)
DVI is a digital interface standard. DVI allows direct transmission of the PC’s digital data without
loss.
This adopts the TMDS transmission system and DVI connectors. There are two types of DVI
connectors. One is a DVI-D connector for digital signal input only. The other is a DVI-I connector
for both digital and analog signal inputs.
DVI DMPM (DVI Digital Monitor Power Management)
DVI DMPM is a digital interface power saving function. The “Monitor ON (operating mode)” and
“Active Off (power saving mode)” are indispensable for DVI DMPM as the monitor’s power mode.
EBU (European Broadcasting Union)
The organization also includes broadcasting offices from Europe and North Africa, and it’s role is to
decide various technical standards etc.
Gain
This is used to adjust each color parameter for red, green and blue. An LCD monitor displays the
color by the light passing through the panel color filter. Red, green and blue are the three primary
colors. All the colors on the screen are displayed by combining these three colors. The color tone
can be changed by adjusting the light intensity (volume) passing through each color’s filter.
