Gamma Preset Mode: Basics
What is Gamma?

The correlation between input and output signal
levels for a camera or monitor is known as
gamma. In the case of display monitors, for
example, the relationship between the input
luminance signal and display brightness is
referred to as gamma characteristics.

Generally speaking, when the gamma curve is
linear (γ=1), reproduced images become closer
to what humans perceive with their eyes.
Therefore, as gamma characteristics of display
monitors tend to be darker with halftones it
becomes necessary to alter the gamma curve
closer to linear by sending an image signal with
brighter halftones. This helps to convert colors
more precisely, a process that is referred to as
gamma correction.

In light of the fact that many studios are
gradually replacing CRT master monitors with
next-generation master monitors, a number of
organizations (e.g. EBU, ITU-R, ARIB, and
others) are announcing guidelines for next-
generation master (reference) monitors with
varying specifications.

Gamma Benefits of the DT-3D24G1:
Compatible with γ2.2, γ2.35 and γ2.45
as well as γ2.6 gamma preset modes for
digital cinema environments, the DT-
3D24G1 enables users to calibrate
optimal gamma settings according to
specific operating conditions and
applications (refer to the following page
for applications of each mode).
