projected toward a spherical or cylindrical screen
as well as trapezoidal distortion of an image on a
fl at screen and rotate the image at your arbitrary
angle.
Keystone
When the image is projected either from the top or
from the bottom towards the screen at an angle, the
image becomes distorted trapezoidally. The
function for correcting trapezoidal distortion is
called Keystone Correction.
Note
The Keystone Correction can be adjusted up
to an angle of approximately ±40 degrees
with “V-Keystone” and approximately ±30
degrees with “H-Keystone”.
