Adjusting the Image Quality
The quality of the projected images can be adjusted as follows.
Projecting Easy-to-see Images Without a Screen
(Wall Shot)
When the Wall Shot function is used, images can be projected without loss
of original colour even onto surfaces such as blackboards and coloured
wall surfaces which are being used instead of a screen. For example, if
projecting onto a green blackboard, the projected images would normally
appear greenish and be very difficult to see. The Wall Shot function uses a
sensor to measure the condition of the projection surface and automatically
adjusts the colour of the projected images based on these measurements.
The Wall Shot function also allows shading to be adjusted. If projecting
onto a screen that is located near a window, the Wall Shot function can be
used to obtain clear images when they might otherwise appear faded.
PROCEDURE
The Wall Shot function can be operated using either the remote control or
the projector's control panel.
Press the [Wall Shot] button on either the remote
control or the projector's control panel while the
images are being projected.
When the button is pressed, the current status is displayed on
the screen.
TIP
Wall Shot can be used for adjustment if the projection distance is
within approximately 80–1000 cm (2.6–32.8 ft.). However, this
distance will vary depending on the condition of the projected surface,
for instance if the projection surface is an extremely reflective surface
such as a whiteboard, or if it is a highly non-reflective surface such as
a dark wall.
