recalls the lens focus setting

when the CPL is included in
a presentation.
Electric V shift applies a vertical position offset to the
image. This setting is stored in the FUNCTION and, when
the Screen Management System associates the
FUNCTION with a CPL, a vertical offset is recalled and
applied to the image when the CPL is included in a
presentation. This vertical offset of the image is used to
adjust for any slight displacement in the vertical center of
the image when different aspect ratios are included in a
single presentation.
The ADJUST PROJECTOR group is where the lens
mechanical Zoom and Focus adjustments, and the image
Electric V shift adjustment are located.
To operate controls in the ADJUST PROJECTOR group,
you tap or press and hold the
Plus or Minus buttons.
Prior to adjusting the Zoom, Focus or Electric V shift,
verify that Current Function displays the desired target so
when the adjustment is saved it is applied to the correct
FUNCTION.
Zoom (Image Size)
2
Because the image from the DCP file appears on the
imaging device as a “flat” image it is practical to use
projection lenses that allow you to zoom to properly size
the image to the auditorium screen. The Zoom setting is
associated with the Current Function and recalled when
that FUNCTION is selected on either the PROJECTOR
CONTROL screen or the associated CPL is included in a
presentation. Zoom is a
mechanical adjustment of the
projector lens and should not be confused with any kind of
image manipulation creating a zoom effect.
To adjust Zoom (the image size), tap Menu , tap Projector ,
tap Function Setup , and then either tap, or press and hold,
the Minus or Plus button associated with Zoom
while observing the projected image on the screen. This
adjustment is normally done using the CinemaScope/Vista
Projector Test Patterns (see
“Test Pattern (Select)” on
page 32 ). However, it may be necessary to observe the
actual content (CPL) while setting Zoom to insure that the
screen is properly filled while still not spilling the image
onto the screen mask or surround. In this case, it is
recommended you create a new FUNCTION which is
specific to the CPL using the SRX Controller application.
Focus (Image Sharpness)
The Focus setting is associated with the Current Function
and recalled when that FUNCTION is selected on the
PROJECTOR CONTROL screen or associated with the
CPL. This is a
mechanical adjustment of the projector lens
and should not be confused with any kind of electrical
focus adjustments.
To adjust Focus (image sharpness), tap Menu , tap
Projector , tap Function Setup , and then either tap, or
press and hold, the Minus or Plus button associated
with Focus while observing the projected image on the
screen. Adjusting Focus is usually realized using a DCP
containing a suitable test image and typically only done
during the configuration process. Observing actual Show
content while setting focus is not recommended.
Electric V shift
Allows you to electrically compensation for vertical image
displacement when the aspect ratio of the image is changed
from 2.39:1 to 1.85:1. Refer to Projector documentation
for additional details.
The Electric V shift control shows the relative vertical
“position” of the image on the auditorium screen and is
associated with the Current Function. In addition, this
control has a numeric display which allows you to position
the image to a known location based on the content aspect
ratio.
To adjust the Electric V shift, tap Menu , tap Projector , tap
Function Setup , and then touch & drag the Electric V shift
control to a new setting and release. To make incremental
adjustments to the Electric V shift setting, either tap, or
1.Lens focus is a mechanical adjustment and may take a
few seconds for the adjustment to be realized.
2.Not available when Projection Type is set to “Single
3D”.
