Field polarity
The field polarity function is used for interlaced images. Both rasters of the image could be shifted in a
wrong way (double lines are visible in the image). This can be corrected by forcing the field polarity to
[neg] or [pos]. Use the ENTER key to toggle between [pos] and [neg].
Field select
Default [both]
The field select is only used for interlaced images. One frame of an interlaced image contains two
fields, an even and an odd field. The choice exists to project [both] fields on the screen or only the
[even
] or [odd] field.
Use the ENTER key to toggle between [both], [even] and [odd].
If the active Stereo Compatibility Option is installed, the field select parameter will be changed
into a [left] and [right] selecting parameter which will be selectable for stereo files. This setting
will
then be saved in the active image file.
