L: Projection distance (m/ft)
H1: Lower distance from the lens center to the bottom of the image (cm/in)
H2: Upper distance from the lens center to the bottom of the image (cm/in)
W: Distance from the lens center to the center of the image (cm/in)
Note
• Allow a margin of error in the value in the diagrams above.
• When the distance from the lens center to the bottom of the image [H] is a negative number, this indicates
that the bottom of the image is below the lens center.
