Correcting keystone
distortion of the image
(Keystone)
If a projected image exceeds the adjustable range
using lens shift, and you want to project the
image higher beyond the range, you can tilt the
unit upwards by extending the adjustable front
foot.
* After you have corrected keystone distortion of the
image, the quality of the projection image drops
compared to the image corrected with the lens shift
mechanism. Usually, you can adjust the image position
by shifting the lens.
If the interface side is raised
Adjust the feet in such a way that the unit is level.
You can adjust the feet on the interface side only.
If you extend the foot and tilt the unit, the image will have keystone distortion.
Reshape the keystone distortion as follows:
When the top of the image is wide
If the unit is tilted by up to 15º degrees in an upward or downward orientation, you can correct the image shape.
However, it will be difficult to focus if the tilt angle is large.
If the unit is tilted, shifting the lens will not completely correct keystone distortion.
