The ADJUST PROJECTOR group is where the lens
mechanical Zoom and Focus adjustments, and the image
Electric V shift adjustment are located.
ADJUST PROJECTOR
Save to FUNCTION
To operate controls in the ADJUST PROJECTOR group,
you tap or press and hold the
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)
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 associated with a
CPL. 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
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
40). However, it may be necessary to observe the actual
content (CPL) while setting Zoom to insure that the screen
is properly filled will still not spilling the image onto the
screen mask or surround. In this case, you may wish to
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
Zoom
Focus
(plus) or
(minus)
of the projector lens and should not be confused with any
kind of electrical focus adjustments.
To adjust Focus (image sharpness), tap Menu, 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.
Since adjusting image size to meet aspect ratio changes
causes the lens elements to move, there is a possibility of
loss of focus when a very large number of lens operations
are realized. Selected lenses are equipped with a
"feedback" mechanism that insures the lens focus setting
is realized based on the value stored in the FUNCTION.
Electric V shift (Image V Centering)
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 the Projector
documentation for additional details.
Lower
Electric V shift
The Electric V shift Adjust 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 (image V Centering), tap
Menu, tap Function Setup, and then touch & drag the
Control Bar/Indicator to a new setting and release. To
make incremental adjustments to the Electric V shift,
either tap, or press and hold, the
button associated with Electric V shift while observing
the projected image on the screen. A numerical value is
shown to allow for easy resetting of Electric V shift to a
previous value.
Note: Response to setting the Electric V shift will
experience some delay. You should use the Control
