Random Access Adjustment Mode

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 pressENTER to select.

Eliminate teh deformation by pushing the control stick upwards or downwards until a straight line is obtained.

ENTER will return to Top-Bottom adjustment menu EXIT will return to Geometry menu
