During the official presentation of the new LG G3 from the South Korean company LG, we learned that the camera of this mobile phone brings a novelty that until now we had not seen in any of the mobiles presented in recent months. It is a laser sensor located on one side of the main chamber which lies role in improving the quality of the pictures we took with mobile. But since it is a technology unknown to most users, in this article we are going to take a look at the exact operation of this curious sensor to understand how it benefits us when taking pictures with the camera of the new LG G3.
The first thing to know is that the standard camera built into the LG G3 comes with a sensor 13 megapixel accompanied by a -dual LED flash to improve lighting in photographs taken at night. Just to the opposite side of the flash we find the laser sensor, whose technology responds to the name of LaserAF.
For us to understand its operation well, we must know that this laser sensor works in a very similar way to the laser distance meters that are used in constructions to know the distance that there is from one point to another simply by placing the laser emitter on site indicated. The LG G3's laser sensor also emits small pulses of infrared light that, once bounced off a surface, returns back to the sensor to indicate the distance between the camera lens and the object to be photographed.
And what use is it to us that the mobile knows the distance between the camera and the object we are photographing? Very simple: this is a practically perfect way to ensure that the camera focuses exactly on the scene we want to capture. Before this mobile was officially presented, rumors spoke that this sensor would be exclusively oriented to photographs taken at night. And although the sensor also works during the day, the truth is that its main utility lies in the photographs we take in dark environments. Who has not had the problem that a photograph taken at night appears with excessive lighting on objects that we are not interested in for the snapshot?
Although we will still have to wait to test the LG G3 thoroughly, the truth is that its main camera promises an image quality that could even be a serious competition in the photography section compared to the large smartphones on the market. We will see if this technology has been applied as they have explained to us during the official presentation of this new smartphone. To verify this, we will have to wait until July, when the LG G3 is scheduled to launch in Europe.
