Correcting the Image Shape and Focus Automatically
When the projector is moved or tilted, Auto Shape Correction automatically
corrects focus and any keystone distortion of the projected image.
Auto Shape Correction operates under the following conditions:
•
When the size of the projected image (diagonal length) before correcting the
focus and keystone distortion is from 30 to 100 inches.
•
When the projection distance is about 195.6 to 105 inches (77 to 267 cm).
•
When the installation angle of the projector toward the projection surface is
within 20º right, le, up, or down.
•
A
uto Shape Correction operates even if the size of the projected image
exceeds 100 inches. However, the adjustment may fail depending on
the installation angle of the projector, the brightness of the room, and
the material of the projection surface. If necessary, adjust the keystone
distortion and focus settings manually using the projector menu.
•
When an image is being projected at an angle and has been reduced
using the Zoom & Shi function, keystone distortion may not be
corrected. If the correction fails, adjust the reduction ratio of the image
so that it is closer to 100%.
