Apple patents a system for synchronizing the flashes of several iPhones when taking pictures

The patents related to the iPhone camera do not cease. Today we see one that would allow us to synchronize the flash of a master iPhone with that of other slaves to improve the lighting conditions of a scene, and we can even receive recommendations from it to improve the lighting. Will we see this patent materialized in the next iPhone, or will it simply be one more of those that never see the light?

We’re back with the Apple patents. We continue to see patents related to the iPhone camera, where Apple wants to continue improving so as not to be left behind after the alternatives of Nokia and HTC. The patent they suggest this time is focused on the lighting system, where propose the synchronization between the flashes of several iPhones to take a picture .

There would be an iPhone that would act as a master, and once connected to the other slaves it would be able to send them the trigger signal so that the picture we took would have different points of light. We would be talking about a social photography system, which would be most interesting in low light situations where the main flash alone is not capable of giving the necessary power to illuminate the whole scene.

The patent is not restricted to the iPhone, but talks about devices with dedicated camera or image capture capabilities , which could let us know that this system could be extended to iPad with flash or Android phones (which is quite unlikely). Although we could also think about the iPad or iPod touch as the master device and the iPhone as the slave for the flash .

But this would not be limited to a simple shot with stand-alone flashes, but would first take a test picture to determine the light conditions of the scene, and then set each flash to fire at a certain power . Even the Camera application could give us indications of where we should place the light sources to obtain an optimal picture.

The shooting system would not be by radio frequency or by a photo-sensitive cell, as is the case in photography with reflex cameras, but Apple proposes the use of wireless technology, such as Wi-Fi or Bluetooth. Moreover, as the flashes are LED and can be on for several seconds, the synchronisation would not be as delicate as in studio flashes , where their flash lasts for hundredths of a second.

But this system is not entirely new, as there are already iPhone applications that allow this task, such as External Flash, which allows us just what the patent describes, but in a more spartan way , as it does not establish a measurement of the scene, but triggers the remote iPhone just like that.
