VS+: Vertical lens shift range (up) [%]
VS−: Vertical lens shift range (down) [%]
HS+: Horizontal lens shift range (right) [%]
HS−: Horizontal lens shift range (left) [%]
VS+ = 55 [%]
VS− = 35 [%]
HS+ = HS− = 15 [%]
VS+ [%] = 55 − 3.667 × (HS+ [%] or HS− [%])
VS− [%] = 35 − 2.333 × (HS+ [%] or HS− [%])
HS+ [%] = HS− [%] = 15 − 0.273 × VS+ [%]
HS+ [%] = HS− [%] = 15 − 0.429 × VS− [%]
