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.
