Seagull Correction
Use this correction after the image has been adjusted with top and
bottom bow and keystone. If still a deformation (like a seagull) on top
and bottom of the image is visible, proceed to the seagull correction.
Due to interaction, it is possible that the top and bottom bow 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 stick forward or backward to select the 'Seagull
Correction' and press
ENTER to select.
Eliminate teh deformation by pushing the control stick upwards or
downwards until a straight line is obtained.
