16:10 Screen Formulas:
W = H x 16/10
H = W x 10/16
Screen Diagonal = W x 18.868/16
Projection Formulas:
B (max) = 0.366W
B (min) = 0
C (wide) = 1.274W – 1.457
C (tele) = 2.188W – 1.404
D (max) = -0.053W
D (min) = 0.313W
α (wide) = tanˉ¹ (B/C(wide))
α (tele) = tanˉ¹ (B/C(tele))
Note: For screen sizes not indicated on the projection
tables, use the formulas on page 1.
