Projection Distance and Lens Shift Range
The projection distance refers to the distance between the front of the lens and the
projected surface.
The lens shift range represents the distance in percent (%) by which the lens can be shifted
from the center of the projected image. The lens shift range is regarded as 0% when the
point A in the illustration (point where a line drawn from the center of the lens and the
projected image cross at right angles) is aligned with the center of the projected image and
full width or full height of the projected image is regarded as 100%.
