Gamma correction
This adjusts the signal level to get the correct VT response
characteristics (V: input voltage, T: amount of transmitted
light).
Trapezoidal image correction (Keystone correction)
Depending on the angle of projection, the projected image
will be distorted into a trapezoidal shape, instead of a
rectangular shape.
The projector contains a sensor that detects the angle of
projection in 15-degree increments, and the image is
automatically corrected. This is known as Keystone
Correction.
Projection Distance
This is the distance from the projection lens to the screen.
For a larger screen, the distance becomes longer (the
distance is directly proportional to the screen size).
