Correcting Distortion in the Projected Image 39
Correcting Distortion in the Projected Image
There are two ways to correct distortion in projected images.
•Quick Corner
This allows you to manually correct each of the four corners of the
projected image separately. sp.40
We recommend using Quick Corner to accurately adjust keystone
distortion.
•H/V-Keystone
This allows you to manually correct distortion in the horizontal and
vertical directions independently. You can perform easy H/V-Keystone
corrections by using the [w/] [v/] [</] and [>/ ] buttons
on the projector's control panel, as shown below.
Before performing horizontal or vertical keystone, use the lens shift
function to horizontally center the lens and vertically move the lens to
the top or bottom. Otherwise, the distortion is not corrected accurately.
The projected image may become smaller after you perform
H/V-Keystone.
The correction may not be properly performed for some zoom settings.
Quick Corner and H/V-Keystone cannot be performed at the same time.
When the Keystone correction method is selected from the
configuration menu, the correction method you choose is assigned to the
[w/], [v/], [</ ], and [>/ ] buttons on the control panel. The
default setting for Keystone is set to H/V-Keystone, so when [w/],
[v/], [</ ], a nd [>/ ] buttons are pressed, H/V-Keystone
correction is carried out.
Because Quick Corner and H/V-Keystone correction can be carried out
while projecting a test pattern, you do not need to make prepara tions by
connecting a computer or other equipment.
