E44
Ⅵ 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.
