Note: The uEye LE USB 3.1 Gen 1 camera family supports flash only in triggered mode and not in freerun mode.

Automatic flash

In freerun mode, the automatic flash feature works in the same way as in trigger mode. As a result, the flash output is continuously or almost continuously active (see illustration below).

Manual flash synchronization

It is recommended to synchronize the flash manually in freerun mode. This applies to both rolling and global shutter sensors. In freerun mode, the manual flash synchronization works in the same way as in trigger mode.
