JVC KY-F75 manual  When the shutter mode is Random, E44

5. Others (continued)

Synchronizing flash and trigger (continued)

When the shutter mode is “RANDOM”

•CCD accumulation is performed in sync with the trigger input, and this period is output as the FLASH signal.

•At the same shutter speeds the delay from the trigger input to the FLASH output is almost uniform as shown in Table A below. Also, the pulse width of the FLASH output differs with the shutter speed.

•The trigger input interval is restricted as shown in Table B. Do not input at a shorter interval than the minimum interval shown in the table.

*In the following situations, the FLASH signal is continuously generated in sync with the CCD regardless of the trigger.

●When [Shutter] on the EXPOSURE screen is set to “EEI”.

●When [Gain] on the EXPOSURE screen is set to “ALC”.

●When [Iris mode] on the EXPOSURE screen is set to “AUTO”.

●While AW (Auto White) is operating.

MEMO

•In the condition where the shutter mode is RANDOM, the image quality may deteriorate at the time of FREEZE as noise may be applied or white spots may appear.
