Synchronizing Flash And Freeze - JVC KY-F70B Instructions Manual

Synchronizing flash and FREEZE

To activate the flash when inputting FREEZE, use the FLASH signal of the REMOTE terminal.
The REMOTE terminal located in the rear is also used to freeze an image by means of an
external device other than the FREEZE button itself on the rear panel.
Pin configurations of connectors (
When other shutter mode than RANDOM is selected (
In response to FREEZE input, KY-F70B outputs a flash signal for the CCD accumulation
period of the next frame.
The time required for flash output from FREEZE input depends on the timing of the FREEZE
input and shutter speed. In addition, the pulse length of the flash output differs depending on
the shutter speed.
Since the diagram below is the timing chart when in the SXGA mode, CCD OUT and MONI-
TOR OUT are synchronous. However, the timing of MONITOR OUT will be asynchronous with
CCD OUT when in the VGA mode and there will also be no WEN output.
When in the VGA mode, FREEZE input is ignored until the FREEZE screen is completely
displayed on the monitor.
Even in the SXGA mode, FREEZE input interval for high speed shutter has to be at a mini-
mum of 3 frames (405ms).
When the FREEZE cancel mode is set to MANUAL, the FREEZE input for FREEZE cancella-
tion will not output a FLASH signal or WEN.
