Note
f This illustration is prepared on the assumption that the projected image size and position have been aligned to fit full in the screen.
f This illustration is not in accurate scale.
f The lens optical axis is the symmetrical axis passing through the center of the optical image system. This does not match with the image
center position at the home position. The home position is an origin position of the lens shift (vertical position and horizontal position of the
lens) based on the calibration result.
