Introduction of Huawei p40 mobile phone camera function

Huawei P40 series mobile phones were released on March 26th, 2020. It has three models, namely P40, P40 Pro and P40 Pro+. Domestic pricing will be announced at the domestic press conference in April, with P40 and P40 Pro taking the lead in selling, while P40 Pro+ will have to wait until June.

★ Highlights at a glance ★

-11.28 inch RYYB four Bayer main cameras, about 50 million pixels, supporting full-pixel dual-core focusing (full range)

-5x periscope telephoto camera with RYYB CMOS (P40 Pro).

-? 10x periscope telephoto camera with equivalent focal length of 240mm (P40 Pro+)

-? The focal plane consists of11.54 inch 3:2 CMOS and a lens with an equivalent focal length of 18mm, which supports high-speed slow-motion shooting at 7680FPS and zoom microphone (P40? Pro and P40? Pro+)

-Huawei XD? The fusion image engine and the third generation AI image engine support AI gesture capture, AI eliminating passers-by and AI anti-reflection (omni-directional).

★ Specification comparison ★

Similar to the situation of Samsung S20 series, Huawei P40 series also has three products with different sizes. The smallest P40 has many simplifications, such as resolution, HDR support, main camera anti-shake, wide-angle lens, ToF, front camera, super slow motion, wired charging speed, wireless charging, waterproof and dustproof level. ...

Once again, the "optical zoom" on most mobile phones is essentially to connect several fixed-focus cameras with digital zoom, and these cameras usually have different CMOS specifications. However, the "optical zoom" on cameras and camcorders completely depends on the change of lens group position, which will not affect CMOS specifications, and can also realize smooth and continuous angle change. Mobile phones usually take the main camera with an equivalent focal length of 24-30mm as the focal length of 1 times, so the super wide-angle lens becomes 0.5x and 0.6x. ..

Main picture: CMOS size has increased again, but there is a discount for daily use.

P40 is equipped with11.28 inch four Bayer RYYB CMOS (model or IMX700), with an effective pixel of about 50 million. This is the largest CMOS size of mobile phones on sale, which is about 8% higher than 1 100 million pixel CMOS of Xiaomi and Samsung. The size of a single pixel is 1.2μm, which is 4 1 in daily shooting, and the equivalent size is about 2.4μm m, which is not only the same as the fusion size of Samsung S20 Ultra in daily shooting (1 2 million pixels), but also the same as Sony RX 100 series and Canon G7x/.

Paired with this CMOS is a lens with an equivalent focal length of about 23 mm. It should be noted that Huawei chose to design "1.0x" as 27mm, and then it can use this CMOS when it is "0.8x".

In addition to its large size, this CMOS also supports full-pixel dual-core AF, which means that it actually has about 654.38 billion photodiodes (but it can't directly output photos with 654.38 billion pixels). Huawei calls this kind of focusing "8-core focusing" because in daily shooting, four adjacent pixels are regarded as one use. It should be noted that Huawei P40 series cannot support omnidirectional focusing like IMX689 used in OPPO Find X2 series.

Finally, the main camera of P40 Pro+ has OIS anti-shake and still uses SMA deformation memory alloy to drive the anti-shake motor.

Ultra telephoto: 10x magnification, equivalent focal length of 240mm.

P40 Pro+ adopts Huawei's second generation periscope telephoto camera, and the equivalent focal length is increased from about 125mm in P30 Pro to about 240mm. Although the CMOS size of telephoto lens is much smaller than11.28 inch, it is surprising that the size of mobile phone and periscope lens can reach 240 mm.

Judging from the structural diagram displayed at the press conference, this super telephoto lens of P40 Pro+ is indeed very accurate, and the light has been refracted five times inside the fuselage. At present, we don't know the size of this CMOS, only know the effective pixel is 8 million, and the aperture is F4.4 It should be noted that the 10x telephoto camera of P40 Pro+ does not use RYYB CMOS as the 5x telephoto camera of P40.

Finally, Huawei also equipped P40 Pro+ with 3x telephoto camera with the same specifications as P40, with an aperture of F2.4 and an equivalent focal length of 80mm, which supports optical image stabilization. So the focal lengths of the four imaging cameras of P40 Pro+ are 18mm, 23mm, 80mm and 240mm respectively? ——? This means that 28-50mm, which is widely used in daily life, needs to rely on the digital zoom of the main camera.

*? The telephoto lens of Samsung S20 Ultra consists of a four-Bayer CMOS with about 48 million pixels and a lens with an equivalent focal length of about100 mm. If it can be output with 48 million pixels, it is equivalent to "1/4 inches/kloc-0 after being cut to 1/4". However, after using S20 Ultra, ET found that telephoto can only output photos of about1200,000 pixels, which is really not as good as Huawei P40 Pro+.

Super wide angle:11.54 inch outsole as Mate 30 Pro.

P40 Pro+ uses the same "focal plane" as Mate 30 Pro as a super wide angle, and has a lens with an equivalent focal length of 1.54 inch, a 40-megapixel CMOS (model or IMX608) and 18mm. The ratio of this CMOS is 3:2, and 4 1 in daily shooting is 3840×2592. In low light, 16-in- 1 achieved better 1080P high-sensitivity image quality. The single pixel size after 16 and 1 is equivalent to 4.48μm, which is larger than the CMOS of APS-C with 24 million pixels/26 million pixels.

In fact, these functions, Mate 30 Pro should be exactly the same. TechInsights conducted disassembly analysis before, and it has been confirmed that this CMOS(IMX608) is a 4×4 Bayer structure. Huawei is using practical actions to prove that high pixels are just gimmicks, or that large pixels are real.

Although this "focal plane" supports ultra-slow motion of 7680FPS and ultra-high sensitivity of ISO5 1200, it does not have strong macro capability.

Other functions:

Huawei has also introduced an 8-channel color temperature sensor and AI algorithm library, which is believed to help RYYB CMOS provide better color reproduction and improve the color shift under some specific light sources. At the same time, XD Fusion image engine and the third generation AI image engine have also achieved many advanced functions such as gesture capture, eliminating passers-by, and de-reflecting.

It is worth mentioning that Huawei P40 series supports eSIM cards this time. In this way, when using the NM card to expand storage, you can also use eSIM to realize dual card dual standby, which solves the problem that the second SIM card and the NM card cannot be used at the same time. However, this function has not been introduced in official website at present, and there are still some unsettled places with operators.

The above is the introduction of P40 Pro+ camera functions that ET can present to you at this stage.
