Development of mobile phone flash from scratch to ring flash

At the end of September 2000, SHARP was the Japanese mobile operator J-PHONE launched the J-SH04, the mobile phone built-in 110 thousand pixel CCD camera and mobile phone, and the sale of the late October of that year, became the first mobile phone equipped with a camera. Subsequently, many mobile phone brands also started their own mobile phone with a camera, I do not know what month (specific time model has not known), a mobile phone camera in order to solve the problem of insufficient light, the LED flash on mobile phone. By 2006, Sony Ericsson had added xenon flash to its new K790, becoming the first to be equipped with xenon flash, making up for the lack of brightness for LED flash in the dark. After years of development, in the era of intelligent machines, mobile phone camera has been rapid development, while mobile phone flash technology with mobile phone camera technology development, the color temperature of the flash, and then the emergence of a ring flash.

Mobile flash technology continues to develop, the main purpose is still used for dim light places temporary lighting, to bring better effects of photography. The mobile phone flash is generally used LED, and built-in mobile phone, very convenient to use, but LED lights also has many problems, such as lack of brightness, color temperature is not uniform, also gave birth to the color temperature of the flash and flash ring.

From the early LED and xenon flash light

The first mobile phone equipped with LED flash is out of the picture. It's too old. We see that in the era of functional machines, although there are cameras on the phone, many of them have not been equipped with flash. On the one hand, because of the poor effectiveness of the mobile phone cameras, on the other hand, many mobile phones are not equipped with flash because of the cost and technical restrictions.

LED flash

With the development of mobile phone camera technology, the function of machine in the late, a lot of mobile phone camera equipped with a good quality, mobile phone camera quality has also been improved, and no flash mobile phone is very poor pictures in low light conditions, which appear in the mobile phone on the LED flash. So why choose LED as the light source for your cell phone flash?

We know that LED has the characteristics of low power consumption, and small size, which is suitable for small volume mobile phone use, low-power LED flash can also save a lot of power for the mobile phone. But LED lights early in brightness is not high, uneven brightness and so on shortcomings, and to identify the emergence of these xenon flash in the high-end mobile phone.

Sony Ericsson K790 - the first to be equipped with xenon flash mobile phones

Xenon flash is used in many digital cameras, camera xenon flash volume is relatively large, the volume has been solved and the power consumption problems after 2006, Sony Ericsson launched the first mobile phone equipped with xenon flash K790. Xenon flash has higher brightness than the LED flash, xenon lamp effect is relatively uniform, the scope is far, very close to the sun emits light color temperature light, these advantages are not LED flash, of course, the cost is stronger than the LED flash high a lot. Xenon flash has been used on some high-end mobile phones, and the machines are very few. Although it works well, it can not be mainstream.

Fast developing period: double color temperature LED flash lamp

With the quality of mobile phones becoming more and more demanding, white light LED flashes begin to display a lot of shortcomings, of course, the most prominent is the color temperature is not allowed, uneven brightness problems. Lack of double color LED lights can solve the white LED flash, bring more natural soft flash effect.

Dual color temperature LED

Two color temperature flash is the phone back of the hand has two different color temperature flash. At present, most of the mobile phones on the market are using a bright white LED flash, with a slightly darker amber LED warm light to achieve the effect of color temperature compensation. Smart phones with dual flash cameras show higher levels of camera technology, with the main function of improving the quality of picture quality, and making the picture more natural and clear.

Now no mobile phone on the color temperature of the flash is not limited to the 2 LED, part of the mobile phone use 4 or more LED, which not only brings the color temperature of the soft light effect, can improve the brightness of the LED flash.

Annular flash lamp:

Ring Flash

Meizu PRO 6 appeared for the first time on the 10 LED flash ring, is the ring flash advantage when the camera exposure will flash synchronous exposure, the main light source to form an image, and from the main body to form a uniform illumination everywhere, illumination effect. Ring flash Meizu PRO 6 using 10 pieces of LED, bring more high brightness, light more evenly, let the night shoot have better effect. Meizu was then used for ring flash on PRO 6S and PRO 6 Plus.

External flash:

External flash

In addition to mobile phone built-in flash, ASUS launched the external flash accessories in 2015, with the use of ASUS's mobile phone, the external flash is used to compensate for the lack of xenon flash, built-in xenon flash, but the external design and without user acceptance, to no subsequent product. In addition, there are some LED flash on the phone, need to match the use of mobile phone APP, the same experience is not good.
