6.3. Iris video output
This signal can be used for lens iris control in Continuous
and pre-dump modes.
The signal is 1.0 V p-p (with H-sync) from 75
without
termination.
Fig. 13 Iris video output.
The iris video signal is composed to average the video level in the center area of each frame
and can be output as a composite signal with H-sync. As shown in the following figure, each
frame has its own video level which is averaged.
