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.
There are the two types of the Keystone
Correction.
1) The “GEOMETRIC ADJUSTMENT”
method corrects trapezoidal distor-
tion by specifying 4 marks on the
screen.
2) The “H & V KEYSTONE” method fea-
tures corrections to 2 axes (horizon-
tal and vertical) based on numerical
values.
