ENGLISH
This is a description for the 3D-method using this unit, 3D-glasses (sold separately: PK-AG1-B/PK-AG2-
B) and an 3D synchro emitter (sold separately: PK-EM1). Set the 3D TV and 3D compatibility software to
an appropriate viewing standard. For viewing, a separate unit
compatible with 3D playback is needed. For detailed descrip-
tion of other 3D methods, please read specialized books on
this topic. (For the sake of explanation, a simplified and exag-
gerated picture is used.)
The 3D scheme of this unit utilizes the principle of binocular
parallax. It projects with the frame sequential method, where
separately alternating images are produced for the left and
right eye. Opening and closing of 3D glasses fitted with liquid
crystal shutters are controlled in such a way, that video images
corresponding to the right/left eye and are only visible for the
respective eye. As a result, one can watch three-dimensional
images.
Due to the difference of the video images both eyes see, the
brain perceives them in a stereoscopic way. The video images
that can be seen by the respective eyes are artificially pro-
duced. Due to the exposure of the eyes to the respective video
images, the brain is induced to create a stereoscopic image,
which is not present as a real object. In other words, it is a use
of virtual images.

CAUTION
• Please stop watching at once if
you do not feel well and consult a
physician if necessary.
• People who already have a kind of
photosensitivity, sufferers from heart
disease, and people in poor physical
condition should not watch 3D video
images of this device, which makes
use of 3D glasses.
• It is recommended that you take
a break periodically. Length and
frequency of the required break
differ due to individual differences.
Please judge for yourself.
CAUTION
• The comprehensive brain function
to judge stereoscopic vision and
which include a feeling for real
distances, develops while growing
up by touching and seeing real
objects, but in early childhood, it
is still in an underdeveloped state.
Even though there are individual
differences, children under 5 are
still developing. Letting them
frequently watch virtual 3D video
images can be an obstacle for the
development of a comprehensive
three-dimensional feel.
• For younger children may suddenly
become sick, because they continue
watching without realizing symptoms
like 3D sickness or deterioration
of health until after watching 3D
images. Please accompany your
while it watches. And please be
careful when it comes to your child’s
bodily condition and state.
