djusting the 3D Image
The upper 3D screen allows you to view stereoscopic 3D images. You can adjust the apparent depth of
these images with the 3D depth slider.
The Nintendo 3DS system uses binocu-
lar parallax (the fact that your left and
right eyes are located a short distance
apart, causing them to see different
images) to produce 3D images with a
feeling of depth.
If you view the 3D screen from the
correct distance, it displays an image
for your left eye in such a way that only
your left eye can see it, and an image
for your right eye in such a way that
only your right eye can see it. Binocular
parallax then allows you to see 3D
depth in the image.
Viewing the 3D screen from a diagonal or tilted position, or viewing it
with the system held vertically, will not produce a 3D effect. Viewing
it this way could cause you to see double images overlapped or cause
the screen to appear black.
To view the best-quality 3D images
Viewing and Adjusting the 3D Image
Adjusting the depth of the 3D images
You can use the 3D depth slider to adjust the apparent depth when viewing 3D images. If it is difficult to view the image with the
3D slider moved up to the maximum (with the depth set as deep as it will go), try moving the slider to the minimum and then
increasing it in small steps until you find a level where it is easy for you to view the 3D images. Once your eyes are accustomed to
3D images, you may be able to achieve the best-quality image by moving the 3D slider up.
• If the 3D LED is not lit, moving the 3D slider toward “3D” will not produce a 3D image.
• Some software switches between 2D and 3D imagery. With this software, moving the 3D slider does not change the intensity
of the 3D effect.
• It may be difficult to see the 3D effect in locations with strong direct light, such as sunlight.
A note about viewing 3D images
IMPORTANT: The ability to view 3D images may vary from person to person, depending on physical condition,
content of images, and the environment you are viewing them in. A small percentage of people may not be
able to see 3D images at all. If you see double images or have difficulty seeing the 3D effect, turn the 3D
effect off with the 3D depth slider and refrain from using it. The 3D feature can also be turned off with
Parental Controls in System Settings - see page 58 for more information.
Be sure to read the Health and Safety information regarding 3D images at the beginning of this manual
(see page 8).
NOTE: You can use Parental Controls to restrict the display of 3D images (see page 68).
