The formula for picture size and projection distance
[m/cm]
L1 (m) = 0.03658χ
L2 (m) = 0.04572χ
H1 (cm) = –1.6002χ
H2 (cm) = 0.0762χ
W (cm) = ±0.7112χ
[Feet/inches]
L1 (ft) = 0.03658χ / 0.3048
L2 (ft) = 0.04572χ / 0.3048
H1 (in) = –1.6002χ / 2.54
H2 (in) = 0.0762χ / 2.54
W (in) = ±0.7112χ / 2.54
χ:
Picture size (diag.) (in/cm)
L1: Minimum projection distance (m/ft)
L2: Maximum 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.
