LG Launches the G3 Handset

 

LG  has launched a new smartphone, the G3 handset. It has laser-assisted autofocus to help take sharp photos .`

The South Korean firm launched the smartphone in london,the Android-powered device's camera focus in dim light conditions and quickly lock onto moving objects.

LG is marketing its phone's resolution as being "quad HD" - four times the resolution of 720p high definition

 

The G3 features a 5.5in (14cm) screen with 538 pixels per inch making it bigger and higher resolution than both its predecessor, the G2, and Samsung's G5.

However the device's main 13 megapixel rear camera has a lower resolution than Samsung's.

But the camera is enhanced by the Laser Auto Focus function, which LG said allowed it to focus in 0.276 of a second - faster, it said, than a human's brain signals take to reach their hand.

It works by sending out a low-powered laser beam that allows the device to measure its distance from the photo's subject more accurately than "phase detection" - the analysis of contrast and the focus-assist lamps used by some other devices.

"One of the advantages of having an assist beam or laser is that it can help focus in extremely low light and even in total darkness, although the method was typically slow. 

Other innovations announced by LG included the ability to trigger a photograph by making a hand gesture at the phone, which triggers a short countdown before the shot is taken.

The firm suggested that this made the device ideal for "selfies".
