Vertical corner correction (correction to bilateral symmetry by using corners as the center line.) ■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 19
