Radio control for cameras with separate flash units involves wait step before transmitting trigger signal to ensure trigger signal is only transmitted if receiver ready and shutter fully open

摘要

The method involves the camera transmitting radio waves received by separate flash devices, triggering an activation device to activate receivers in range of the transmitter, transmitting a coded trigger signal only detectable by receivers set to the code so only they can output a flash trigger signal and introducing a wait step so the trigger signal is only transmitted if the receiver is ready to receive and the camera shutter is fully open. The method involves the camera transmitting radio waves received by the separate flash devices, triggering an activation device to activate the receivers of flash units within range of the transmitter, transmitting a coded characteristic flash trigger signal only detectable by receivers set to the code so that only these receivers can output a flash trigger signal and introducing a wait step before transmitting a trigger signal that ensures that the trigger signal is only transmitted if the current receiver is ready to receive it and the camera shutter is fully open. Independent claims are also included for the following: an arrangement for radio control of cameras with separate flash units.
