Chapter 7 Glossary
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.
Gamma
Generally, the monitor brightness varies nonlinearly with the input signal level, which is called “Gamma Characteristic”. When the gamma value is low, the
middle tone area is displayed brighter, and darker when high. Changes to the gamma value will not affect contrast. A gamma value appropriate for the
display content should be selected.
HDCP (High-bandwidth Digital Content Protection)
Digital signal coding system developed to copy-protect the digital contents, such as video, music, etc.
This helps to transmit the digital contents safely by coding the digital contents sent via the DVI or HDMI connector on the output side and decoding them
on the input side.
Any digital contents cannot be reproduced if both of the equipments on the output and input sides are not applicable to HDCP system.
HDMI (High-Definition Multimedia Interface)
HDMI is a digital interface standard, developed for consumer electrical appliance or AV device. This standard is issued on the basis of the DVI standard
which is one of an interface specification for the connection between a PC and a monitor. The projected image, sound and control signal without
compressed enable to be transmitted with one cable.
L*
L* is a lightness value based on the CIELUV and CIELAB color spaces. CIELUV and CIELAB are color spaces that describe the relationship between color
and human vision, in which L* corresponds to perceived brightness.
REC709, REC2020
