4:3 Screen Formulas:
W = Image Width = H x 10/10
W = H x 4/3
H = Image Height = W x 10/16
H = W x 3/4
Screen Diagonal = W x 18.868/16
Projection Formulas:
B
= 0.2578W
C
(wide) = 1.361W – 1.68
C
(tele)
= 2.26W – 1.68
D
= -0.055W
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.
