ENGLISH
This is a description for the 3D-method using this unit, 3D-glasses (sold separately: P K -AG1-B) and an 3D
synchro emitter (sold separately: P K -EM1). Set the 3D T V and 3D compatibility software to an appropriate
viewing standard. For viewing, a separate unit compatible with
3D playback is needed. For detailed description of other 3D
methods, please read specialized books on this topic. (For the
sake of explanation, a simpli fi ed and exaggerated 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 fi tted 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 arti fi cially 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.
