5.1.2 Fast Shutter Cyclic Mode

In this shutter mode, the camera generates its own synchronization signal and cyclically carries out the

internal shutter operation. The discharge and transfer repeats in every ﬁeld at a predeﬁned timing. The

discharge occurs in every line and stops at the deﬁned timing in one ﬁeld. The duration between the last

discharge and transfer determines exposure time.
