Patent 8,363,157, granted by the US Patent and Trademark Office, documents how LED lighting could be used to give a mobile device the ability to fire with multiple flashes.

Relating to "flash mechanisms for digital cameras that are incorporated into mobile communication devices such as smartphones and tablet computers", the patent documents how a smartphone's shots could be improved by boosting flash capabilities.

As shown, one hypothetical design for the LEDs would ring the LED lights around the lens, where they could be selectively used in different conditions to take the best picture possible. Google's patent noted that different set-ups could be used to ensure that the flash modules could individually activate, be triggered at the same time or used individually to remove particular shadows in poor lighting. It may also be possible to take pictures in succession to shoot the same image with different light settings.

In addition to rapid-fire shots, Google takes dynamic-range imaging into consideration. The possibility of high dynamic-range imaging is in the cards, as a phone could take a series of shots and then merge them together to create the best image possible. The patent said that "such images may appear to have greater colour, contrast or depth than a regular single image of the group would have".
