8.8.4 Exclusive video output signal for iris control
This signal can be used for automatic lens iris control in Continuous and RCT modes.
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. This signal is always output from the
No. 4-pin of the Hirose 12P connector and can also be output from the Hirose 10P AUX
connector as a factory option.
The following drawing shows the waveform of the iris control video signal. This signal is
output with the same video level within the same frame and the average is recalculated
with each new frame.
