Curved Surface Correction Range for Camera Assist You can correct the image shape if the curved surface is a part of an exact circle. The values in the table are the minimum values for R/L shown in the illustration. They are determined in the following conditions: Projecting at maximum zoom R is 280 cm or more Projecting a 150 inch image per one projector You may not be able to correct the image shape if the value is lower than the R/L value in the table. You can confirm the maximum projection distance (L) using the following formula.
L = R/value in the table Horizontally curved surface (concave) A Screen B Center of the circle of which the curved surface is an arc L Projection distance R Radius of the circle of which the curved surface is an arc Top view 30 L R Lens Type ELPLX03 ELPLU05 ELPLW07 ELPLM12 ELPLM13 ELPLM14 Vertical lens shift: Home position Side view - 0.96 0.67 0.50 0.38 0.25 Vertical lens shift: Top Side view 2.86 0.96 0.67 0.50 0.38 0.25
