What are the advantages of mobile phone LED fill light?

The photo environment of mobile phones is very different. First, the light environment is flickering, the focal length is flickering, and users are unwilling to take pictures. So how can we get the photo effect that consumers want? Mobile phone manufacturers have started the idea of LED in mobile phone photo fill light. Please see the full text for details.

As an energy-saving light source, how to use LED? Let's take a look at the new usage of LED in the following mobile phone fill light:

Apple True Tone and retina flash

First of all, let's take a look at how Apple, which pursues the ultimate, uses the flash.

I believe many people still remember that since the iPhone 5s, Apple has used the True Tone dual-color LED flash in the rear lens "iSight Camera" to adjust the color temperature and improve the photo shooting effect.

IPhone 6s rear lens True Tone two-color LED flash

In order to meet the needs of selfie lovers, Apple added the "retina flash" function to the front lens for the first time in 6S, which is a special technology different from other brands of mobile phones. Now Apple has also moved the True Tone flash technology to the front lens, but you can't find the LED flash at the top of the screen, because Apple directly uses the LED backlight retina display as the front lens flash.

However, the brightness of the light emitted by the backlight of the display is not enough to supplement the light, so Apple has adopted a special display chip, which can triple the flash brightness of the display. When the user takes a selfie, the display screen will pre-flash to detect the surrounding light, and then the flash will flash according to the ambient light to take a more realistic and natural photo; Even in low light environment, the retina flash with front lens can achieve good shooting effect.

The custom display chip is specially designed, which can increase the flash brightness of the display by three times.

In fact, as early as a few years ago, someone tried to fill the light with iPad. Now Apple combines the display screen of mobile phone with flash technology, which makes it more convenient to take selfies in the future.

It is said that in order to obtain higher brightness, more concentrated light field and smarter fill light, Apple will use CSP back-illuminated dual-color temperature flash in a new generation of mobile phones.

The soft moonlight of vivo

VIVO exposed all the new LED lighting technologies of the flagship product X7 in vivo community:

Advantages of moonlight soft light+front 1600W pixel

Vivo's advertisement

● vivo X7 newly added moonlight soft light: It simulates the apple light in the studio, making the photographer's skin ruddy and shiny, and the skin color is more uniform and beautiful.

● Equipped with 1600W front camera sensor: Self-timer has never been so clear: the image is brighter and the picture quality is more transparent.

● At the same time, with the unique night beauty algorithm: even if it is dark at night, it is beautiful.

With such cool and intimate functions and configurations, I believe you will be amazed by yourself when you use vivo X7.

Such a vague advertising word implies that the LED in the X7 product of vivo Company can supplement the light in the frontal shooting. As for how to realize it, whether to adopt Retina technology similar to Apple needs further study.

Samsung's new mobile phone breathing light exposure: Surround the rear camera.

Recently, according to foreign media reports, Samsung is going to launch a brand-new LED in its new mobile phone to inform breathing light, and its name is "Intelligent Luminescence". Unlike the traditional breathing light, Smart Glow surrounds the lens of the rear camera and lights up automatically when the phone receives the notification. Users can choose to set up important message notifications, including messages, incoming calls, traffic reminders, electricity pre-warning, etc.

In addition, it is worth mentioning that Smart Glow is not limited to replacing ordinary LED breathing light. Because it is located on the rear camera, users can also take selfies with this breathing light. Generally speaking, the performance of the rear camera is due to the front lens. Smart Glow flashes when the camera detects a face, and automatically takes a picture after a few seconds.

It is expected that Samsung will launch this breathing light design in the upcoming Galaxy J2(20 16), but whether Galaxy Note 7 supports it needs further confirmation.

Meizu's dual color temperature CSP technology LED flash

Ring flash is a highlight of Meizu PRO 6, and five pairs of double color temperature flash forms a ring. The advantage of this design is that it can make the fill light more uniform and sufficient.

Some media pointed out that the main camera fill light technology of Meizu Pro6 project is outstanding, which is not only reflected in its use of five pairs of dual-color temperature flash lamps, but also reflected in its highlights and excellent lighting technology. Then how did it do it? In the application of mobile phone flash, taking Meizu Pro6 project as an example, such a small flash space needs to put 10 led, and it has dual color temperature, which is difficult to realize in general technology, but CSP can. And this advantage of high optical density and small size will be applied in many different places.

Ring flash consisting of five pairs of * * * ten LEDs.

Summary: The above are several new applications of LED fill light in mobile phones recently. It is believed that with the development of LED packaging technology, especially the application and improvement of CSP, more LEDs will be better applied to mobile phone fill light. Moreover, with the improvement of intelligence level, the main chip can detect and obtain the information of ambient light more accurately and give a more suitable lighting scheme, so that the auxiliary function of LED will be more powerful.
