Correcting Distortion in the Projected Image
The following operations explain how to correct distortion in projected
images and how to switch between correction methods.
a
• When correcting distortion in the projected image, the screen size is
reduced.
• You cannot combine multiple adjustment methods. For example, if
you use H/V-Keystone to correct the projected image, you cannot
make additional corrections using Quick Corner.
H/V-Keystone
Manually correct distortion in the horizontal and vertical directions
independently.
Correction range
If the lens shift is in the center, you can correct distortion when the
projector's angle of tilt in relation to the screen is up to 30 degrees vertically
and 20 degrees horizontally.
Arc Correction
Fine adjustment of the curved distortion caused by slack or shrinkage of the
screen.
a
This function allows you to fine tune curved distortions in the image.
However, you may not be able to correct distortions for images
projected onto curved surfaces.
Correction range
You can make corrections in 0.5 pixel increments within the following
ranges.
When top center (A) or bottom center (A') are selected:
You can correct by a maximum of 7 pixels vertically and 3 pixels
horizontally.
When one of the other correction points is selected:
You can correct by a maximum of 7 pixels vertically and 110 pixels
horizontally.
Point Correction
When multiple images overlap, you can fine tune the areas that overlap.
Divides the projected image by the grid and corrects the distortion by
moving the point of intersection from side to side and up and down.
You can also use this to correct small and partial distortions.
