Abstract:
The present invention generally relates to the field of communication between electronic devices used for photography. In particular, the invention relates to a method, transmission unit, system and computer program for wireless communication between a camera and at least one remote flash device, such as photoflash units and related equipment. More in particular, the invention provides a way of controlling a plurality of flash devices from an intermediate radio transmission unit mountable on the camera, and utilized a delay a sequence flash control sequence so as to synchronize the function of the camera and the remote flash devices during image acquisition. Further the invention provides a way of controlling in the photoflash units settings for the main flash, wherein the setting are the last settings determined by the camera when the intermediate radio transmission unit was in a TTL-mode.

Claim (Index 16):
A method for adjusting a power relation between a plurality of different remote flash devices using through-the-lens (TTL) flash control and an intermediate radio transmission unit for wireless transmission of radio signals to the remote flash devices and for bi-directionally exchanging signals with a camera via a physical connection between the intermediate radio transmission unit and the camera, the method comprising the steps of:\n receiving information or setting by the respective remote flash devices the amount of power that the remote flash devices should use for their respective preflashes; receiving by the respective remote flash devices a preflash activation signal received from the camera via the intermediate radio transmission unit; emitting at the same point in time from the respective remote flash devices preflashes with a power relation according to the received information or setting received by the remote flash devices, wherein the power relation is adjusted between the plurality of different remote flash devices using through-the-lens (TTL) flash control; receiving by the remote flash devices one common amplification based on the preflashses to be applied during subsequent main flashes from all of the different remote flash devices, said one common amplification from the camera via the intermediate radio transmission unit; receiving by the remote flash devices a main flash activation signal from the camera via the intermediate radio transmission unit; applying in the remote flash devices the one common amplification to the power for the respective preflashes; and emitting at the same point in time from the respective remote flash devices main flashes with a power relation corresponding to the power relation for the preflashes.
