Section 1: Introduction
4.2
Image Formats
The two standard types of cinema displays-flat and scope-differ in their width-to-height aspect ratio as shown
below:
Achieving either of these displays from a wide variety of incoming source material depends on proper settings
in the projector as well as certain theatre conditions.
4.2.1 Projector Variables: Electronic and Auxiliary Resizing
Because the native resolution/format of the CP projector closely matches the flat aspect ratio (the native
resolution being only slightly wider, at 1.89), the projector can essentially show incoming flat images through
its standard zoom lens. Scope source material, however, is typically squeezed electronically-that is, it is
distorted into a narrow image (characterized by unusually thin people!), and then its pixels are stretched
horizontally through the auxiliary lens so that the full 2.39 image width appears on screen. The image becomes
wider but not taller. See
Figure 4-5
.
If the incoming material has not been pre-squeezed by the distributor, you can squeeze it by using a source file
in which the combined settings for 1) incoming source resolution and 2) desired aspect ratio define the
necessary compression. The incoming material will then be squeezed into a narrower area on the projector's
DMD panels, with the final aspect ratio setting determining the actual degree of compression. Refer to
Section
3.5 Using the Touch Panel Controller (TPC)
for more information about choosing Source menu settings.
