The future of dual camera is here? Analysis of Nubian Z 17 Photographing

IT 168 evaluation On June 1 day, Nubia officially released the new flagship product of Z series: Nubian Z 17. After the conference, Bian Xiao got this new product for the first time. After a simple experience, this product left a very good impression on Bian Xiao in all aspects. The most eye-catching thing is undoubtedly the brand-new "full color" dual-camera scheme. Many small partners are not familiar with this plan. After all, Nubian Z 17 is the first product equipped with "full color" dual camera. So, today Bian Xiao will give you an analysis of this plan and see what is commendable.

Traditionally, Bian Xiao will tell you about the configuration of this Nubian Z 17. Although this product impressed many small partners, after all, among many flagships equipped with Qualcomm's flagship Xiaolong 835, Nubian Z 17 also has nubia UI5.0 added by intelligent AI. In addition to the traditional all-metal version, there is also a brand-new aurora blue color scheme blessed by glass metal technology, plus a still fresh borderless design. Of course, in addition to the above, there are also the world's first commercial 8GB Universiade and the first title with "full color" dual cameras, which also adds a lot of points.

Ok, before it's too late, let's start the feature film.

Nubian Z 17 image analysis: powerful hardware blessing

As the first product equipped with "full-color" dual cameras, Nubian Z 17 has a dual camera combination consisting of two CMOS, namely, 23 million pixels (IMX3 18) and120,000 pixels (IMX362). The specific parameters of these two CMOS are as follows:

"Sony IMX3 18:

It belongs to Exmor RS series, and the sensor structure belongs to stacked CMOS, with CMOS area of 1/2.6 inches and unit pixel size of 1 micron ... It has 22.5 million effective pixels and can output images with the highest resolution of 5488*4 1 12. In terms of video recording, IMX3 18 supports shooting 4K resolution video with a maximum of 30fps, and has built-in brand-new hybrid focusing system and electronic anti-shake technology.

"Sony IMX362:

It has12 million effective pixels, the CMOS size is 1/2.55 inches, and12 million pixels are composed of 24 million photosensitive cells, so the pixel per inch of IMX362 is as high as 1.4.

micron

And the sensitivity is higher than ordinary1.12 μ m.

The sensor is 56% higher. Pixels with sensors can be used for PD detection, so each pixel can be imaged completely without affecting the image quality, and the fastest focus can be achieved in 0.03 seconds (

.

Simply put, Nubian Z 17' s dual-camera scheme has taken a completely different road from other brands.

"By adopting a lens group consisting of two cameras with high pixel (IMX3 18) and high sensitivity (IMX362), the product has high pixel resolution and high sensitivity without losing the CMOS original with high sensitivity.

This combination can be said to be practical.

Solved a worldwide problem of mobile phone photography: "High resolution and high sensitivity can hardly exist at the same time.

In this respect, Nubian's solution is obviously ahead of many mobile phone brands, which is commendable!

After Bian Xiao's explanation, I believe everyone can't wait to know what the imaging effect of Nubian Z 17 is. Please look at the following example.

"Nubian Z 17 photo analysis: sample analysis.

▲ Nubian Z 17 sample 02 ()

In the case of relatively sufficient light, the high resolution of IMX3 18 in this dual-camera scheme is well interpreted. It can be seen that the details circled in the sample can be well displayed after enlargement, and the details can also be well displayed under the complex lighting conditions of sample 02.

▲ Nubian Z 17 Sample 04 ()

In the dark evening and late at night, the high-sensitivity advantage of IMX362 in Nubian Z 17 dual camera is completely revealed, especially in the sample 04. In this case of insufficient light, the picture feels relatively pure, and the noise is not as much as expected after actual amplification, and thanks to the advantage of high pixels, the detail loss is acceptable.

▲ Portrait mode proofs ()

Portrait mode (double-shot blur), Nubian Z 17 portrait mode.

Version 2.0, in which Nubia added artificial intelligence algorithm to support 17 highest level fuzzy adjustment and 3D face detection, which can intelligently identify portrait contours and optimize fuzzy range. You can also look at the actual proofs, Nubian Z 17.

The progress of dual-camera blur is obvious. Nubian Z 17 can deal with blurred edges well, whether it is far focus or near focus.

Full text summary:

▲ Nubian Z 17

Generally speaking, Nubian Z 17 has been upgraded in both hardware and software. In particular, the adoption of "full color" dual cameras makes Z 17 photos have high resolution and dark light shooting ability, without losing other large sensitive CMOS. It can be said that the overall performance of Nubian Z 17 can also be in an excellent position in the current flagship mobile phone.

Through the dual-camera lens group composed of two high-pixel, high-sensitivity CMOS cameras, the product can be imaged in dark light and has high image quality. This combination is considered to effectively improve the overall imaging capability of the mobile phone. but

This is exactly what the single camera or even other dual-camera solutions can't do at present, and the birth of this dual-camera solution directly solves the development problem of mobile phone CMOS, and perhaps this is the future of dual-camera.
