Lens Shift Range
The lens shift range (VS, HS) is represented in percentages (%) displaying how much the lens can be shifted. When a line drawn from the lens center (C) crosses the projected surface (A) at right angles at the point (D) and if the point (D) is identical with the projected image center (B), the lens shift range is regarded as 0% while the full height and full width of the projected image are regarded as 100%.
