a device in a camera that synchronizes the action of the camera shutter and a flash lamp. In many modern cameras, the synchronizer is equipped with a regulator that makes it possible to vary the time interval between the actuation of the shutter and the flash lamp. This type of regulation is necessary when switching between operation with a flashbulb and operation with an electronic flash.
