E44

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.
