Seagull Correction
Use this correction after the image has been adjusted with top and
bottom bow and keystone. If a deformation is still visible (like a seagull)
on top and bottom of the image, proceed to the seagull correction.
Due to interaction, it is possible that the top and bottom bow will
have to be readjusted after adjusting the seagull correction to obtain
an improved image. The default value on the bar scale of this
correction is 50.
Push the control disk up or down to select the ' Seagull Correction ' and
press ENTER to select. Eliminate the deformation by pushing the
control disk upwards or downwards until a straight line is obtained.
ENTER will return to Top-Bottom Adjustment Menu. EXIT will return
to Geometry Menu.
Horizontal Size Adjustment
Push the control disk up or down to highlight H SIZE on the Geometry
Menu and then press ENTER.
ENTER will select horizontal size adjustment
EXIT returns to Random Access Adjustment Mode Menu
ADJUST returns to Operational Mode
Adjust the horizontal size by the control disk to the right or to the left
until the exact image width is obtained.
Note:
- if the internal # pattern was selected, this pattern remains on the
screen.
- if the genlocked pattern was selected, the external source will be
displayed.
A bar scale and a numeric indicator help to gauge the horizontal size
adjustment.
EXIT will return to the Geometry Menu.
