Projection distance formula
To use an image size not listed in this manual, check the projected image size SD (m) and use the respective formula to calculate projection
distance (L).
The unit of the formula is all “m”. (Value obtained by the following calculation formula contains a slight error.)
When calculating a projection distance using image size designation (value in inches), multiply the value in inches by 0.0254 and substitute it
into SD in the formula for calculating the projection distance.
r
When the image aspect ratio is 16:10
Minimum projection distance
(LW)
L = 1.2976 x SD
- 0.0385
Maximum projection distance
(LT)
L = 2.7999 x SD
- 0.0379
