Geometry adjustment
The process of digitally manipulating the position of each pixel of the source image to a different position in the pro-
jected image.
About this section
Geometry adjustments make this projector more flexible to be used in wide variety of curved and flat-screen applications, ranging
from flat or straightforward cylindrical displays to the wildest shapes that can be imagined. By pre-distorting the image inside the
projector, a correct geometry can be achieved on curved screens without requiring additional computational power on the image
generator.
This section explains the geometry adjustment principle and lists the procedures to perform geometry adjustment: this enables us
to correct vertical and horizontal keystone, to create bows to meet the shape of cylindrical and spherical screens and to align the
channels onto each other in a multiple channel display setup. It is at all times possible to reset geometry mode by mode (starting
from the lowest mode, being 33 x 33).
