3D BASICS: SETUP AND RECORDING METHODS
Setting Up the DT-3D24G1
Advantages: In addition to a wide variety of
camera- assist functions, a number of
features that are specific to 3D recordings
such as the 3D Cursor and Grid Modes are
also available.
Basics of 3D camera recording
There are two methods of making 3D recordings, either of
which can be used to suit specific requirements.
Parallel method: The two cameras are positioned in
parallel with wider disparity (two cameras placed further
apart) used to increase field depth, while a longer
convergence point makes images appear to pop up.
When the disparity is widened, however, image
deterioration is likely to occur in the background.
Convergence method: When the divergence angle is
widened significantly, this will cause the subject matter
to shift behind the screen surface and result in image
deterioration.
Parallel method: Depth and pop-up
effects cannot be mixed into a single
scene.
Convergence method: Excessive
divergence angle can cause too much
disparity, requiring keystone adjustment
of the image.
When compared to conventional video recordings, the setting up of
3D recordings can take up to three times longer as lengthy camera installation
and the proper adjustment of depth and pop-up effects are required.

Benefits: The DT-3D24G1 not only speeds up
the 3D recording process but also helps to create
3D recordings that are more comfortable to view.

3D BASICS: POP-UP AND DEPTH PRINCIPLES

600mm
parallax!
The human eye cannot
perceive images in 3D when
the divergence angle
exceeds two degrees.
In this case, the human eye will not
perceive background scenery in 3D.
3 meters from the
camera to the object.
30 meters from the object to
the background = 600mm
binocular parallax.
3D BASICS: FUSION DETERIORATION
The object will be
viewed on the
screen surface.
TIPS:
1) Guidelines for background percentage
gaps of two images:
Hollywood production concerns
recommend a display ratio of less than
1.7%.
Japanese production concerns
recommend a display ratio of less than
2.0%.
2) Binocular parallax for pop-up or
background effects should be
maintained at a maximum between 50
- 60mm to prevent eye fatigue and
other adverse effects when viewing 3D
video content.
θ=-11°
When a recording is made in 3D with the
background at a distance and an object in
the near foreground simultaneously, the
human eye will perceive only the object in
the foreground in 3D and not the
background scenery.
This is because as the distance between
the subject in the foreground and
background increases, binocular parallax
widens significantly.

3D CREATION MODES: 3D CURSOR MODE
3D Cursor Mode
Features: Enables the easy checking and
adjustment of binocular disparity during recording
or editing.
Advantages: In addition to facilitating binocular
disparity adjustment on-screen, more efficient 3D
scaling is assured via disparity values displayed in
the number of pixels and percentages for negative
and positive depth. This means that the counting,
measuring, and/or calculating of pixels are no
longer necessary.
Benefits: Warnings are provided when values
exceed established tolerance levels, helping to
drastically reduce the time required for 3D content
production.
NOTE: When binocular disparity values surpass
2.0%, normal viewing without adverse health
effects may become difficult for certain viewers.
Binocular disparity values
are displayed in the number
of pixels and percentages.
Red cursors
are warnings.
How it works: On the screen, 3D Cursors or the line
markers of V for left (dash dot), V for right (solid line) and
H (dashes) are shown. There are two sets of Cursors,
GroupA in green and Group B in purple, either of which
can be used to finely adjust levels of depth or pop-up; the
H line is used as a horizontal guide.
12

3D CREATION MODES: GRID MODE
Grid Mode
Features: Grids are used to facilitate the
checking of gaps in depth and pop up.
Advantage: By displaying grid lines over the
screen with pixel values shown on the top
right corner of the screen, variable scaling
helps in determining the ideal positions of
left and right images instantaneously.
Benefit: As the size of the grids is variable,
gap values can be easily checked by
selecting the optimum grid size. And this
makes counting the number of pixels or
calculating percentages unnecessary.
Tips: Both the 3D Cursor and Grid
Modes can be used to measure the
binocular disparity of 3D effects.
3D Cursor Mode is useful for
obtaining the correct value of
binocular disparity of a specific
position, whereas the Grid Mode is
helpful for checking the overall
picture as it is especially suited for
measuring more than three different
3D effects on a screen.
There are two grid displays, Normal and
Center Window, which can be selected
by pressing the SELECT button.
The variable grid lines
can be adjusted by
turning the POSITION
knob on the front panel
to stretch or
squeeze grids
into desired
sizes.

3D RECORDING CHALLENGES AND SOLUTIONS
14
3D recording challenges DT-3D24G1 solutions
Precise adjustment of vertical position gaps
between the left and right cameras to prevent
eye fatigue and other adverse effects.
Preventing vertical and horizontal rotation or
inversion of one or both images caused by
different camera rig settings.
Creating top-quality 3D content that will not
cause eye fatigue and other adverse effects.
Convenient camera-assist functions help in adjusting
vertical position gaps and correcting left and right images
regardless of the camera rig setting selected in advance.
The approximate counting, measuring, and/or calculating
of pixels are no longer necessary thanks to handy
functions such as Cursor Mode and Grid Mode. The value
of pixels and percentages are clearly displayed to help in
determining the correct amount of binocular disparity.
Optimum results assured:
Usually with conventional 3D recording methods, only a few scenes can be recorded
in one day and these must be checked after returning to the studio. But the DT-3D24G1
is capable of delivering up to three times the recording volume thanks to user-friendly and
intuitive functions as well as the superb mobility provided by its lightweight and compact design.
What’s more:
One of the most important topics in the field of 3D content creation today is how to prevent
adverse health effects that some viewers can experience when watching 3D videos.And the
DT-3D24G1 helps to alleviate this phenomenon by making it easier for creators to determine
whether 3D effects are too extreme for a given production.
Therefore, 3D creators will be pleased to know that:
When properly used, the user-friendly and intuitive features of the DT-3D24G1 ensure
the creation of high-quality 3D video content, faster and more precisely.

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). 20
