Correcting Distortion in the Projected Image 18
fFitting projected image properly inside the screen
When Quick Setup detects a "frame" (detecting 3 or more sides, or top
and bottom sides, or 2 adjacent sides) within the projection area, it
automatically corrects the image so that it fits within the "frame" at an
aspect ratio of 4:3. The "frame" means the borders of the screen,
whiteboard or blackboard.
When 3 or more sides
are detected When top and bottom sides, or 2
adjacent sides are detected
*
* When the projector is mounted from the ceiling, the image will be corrected
so that the bottom edge of the frame, such as the screen, fits inside the
projection area.
When no border
is detected When the frame is
horizontally long
q• Quick Setup can provide effective correction when the
borders of the projection surface stand out clearly, such as
a white screen with black borders. When protecting
images on a blackboard, for example, you should stick a
large-sized sheet of white paper on the blackboard.
• Quick Setup can be used to carry out correction within the
ranges given below. If the distortion is outside these
ranges, correction will not be carried out correctly.
Furthermore, if the image is distorted both vertically and
horizontally or if the zoom has been adjusted to "W", the
correction range will become narrower than the angles
given below.
- When correcting to within a border
Vertically: Approx. 45°Horizontally: Approx. 20°
- When projecting onto a surface without a border
Vertically: Approx. 45°Horizontally: Approx. 15°
• Quick Setup sometimes does not function properly when
the distance to the screen is 7.5 m or more. If this happens,
carry out adjustments manually.
• The state of the projection surface (flexing, patterns and
so on.) or external light sometimes prevent Quick Setup
from functioning properly since it uses a sensor to
perform correction. If this happens, carry out adjustments
manually.
