IT168 evaluation in the mobile phone ring if the selection of the highest cold brand, it certainly is none other than Sony. The eclectic design style of Sony's mobile phones and the high pricing technology of its best friend Shanghei Technology are all talked about by consumers. However, what Sony is most familiar with seems to be not a cell phone but a camera. Photographing capabilities Apple, Samsung, and Huawei, who have been well-received in the industry, have all adopted Sony's custom-made cameras. Most of the other flagship models of Sony's flagship models are equipped with Sony CMOS image sensors. Sony's latest Xperia XZ is the main image feature, it is the industry's first mobile phone to support triple image sensor technology and five-axis anti-shake recording, then such an attractive camera black technology can ultimately bring outstanding imaging performance ? This article will answer for you.
Triple Image Sensing Technology
The so-called triple image sensor technology is simply the Sony Xperia XZ built-in image sensor, laser focus sensor and RGBC-IR sensor. The image sensor is technically more advanced than the previous model. The laser focus sensor is used for fast close-focusing. The RGBC-IR sensor is the first of its kind in the Xperia series, which mainly improves white balance and exposure accuracy.
1. Image sensor : The image sensor used on Sony Xperia XZ is called the Exmor RS sensor, which is what we often call a stack sensor. Unlike the past, the image sensor that Sony Xperia XZ is equipped with supports predictive focusing technology. An upgraded version of the PDAF phase focus can predict the next motion of the subject on the basis of the increase in filming rate.
2, laser focus sensor : As for the laser focus compared to everyone already very familiar with it, it is common in the flagship mobile phone, the main principle is to use the laser device to shoot multiple laser beams to the subject, by receiving the reflected laser back to calculate the camera and the subject matter The distance between them enables fast focusing. The advantage of laser focusing is not only that it can achieve fast focusing under well-lit conditions, but also that it can achieve fast focusing under dim light conditions, and it will not continuously “pull the bellows†like conventional contrast focusing. However, laser focusing also has its limitations. Sony officials claim that it can only achieve 15cm to 100cm of fast focus, so when shooting large outdoor scenes, laser focus is not available.
3, RGBC-IR sensor :
RGB-IR sensor implementation principle
The RGBC-IR sensor is the focus of the Sony Xperia XZ camera upgrade. Unlike the traditional RGB sensor, the RGBC-IR sensor can additionally record infrared images and colorless pixels, and then adjust the white balance and exposure using an algorithm. In other words, through this technology, the Sony Xperia XZ can restore the color of the subject itself to the greatest degree, even in a complex environment.
From the principle of triple image sensor, the main advantage of Sony Xperia XZ camera is three aspects: focus ability, color performance and white balance control.
Sony Xperia XZ camera experience
Today's mobile phone manufacturers are designing the camera interface to imitate Apple, trying to provide users with a quicker and simpler photo experience. The Sony Xperia XZ remains the same for thousands of years, continuing the interface of similar SLR cameras. Even in advanced automatic mode, you can still see various complex options in the lower right corner of the settings menu, such as automatic browsing photos, grid lines , touch pictures and more. The filter Sony we often use is still not provided, we can only call the menu to adjust the color temperature or brightness.
Sony Xperia XZ camera interface
The design of Sony is too biased towards niche. It is more appealing to geek users and influence lovers. However, as a mass consumer product, the mobile phone still hopes that Sony can study the general consumer habits, simplify the complicated operation steps, and make it easier to take pictures. Also worthy of recognition is that Sony Xperia XZ exhaled the camera is very fast, the actual experience is about the same as the official said 0.6 seconds, lock screen directly press the camera button to open the camera, can be very convenient for life The snap shot.
Another great advantage of Sony cameras is that they have a very rich camera application that allows users to take a variety of creative photos. However, these camera applications are often power-hungry, and occasionally use it for a while, prolonged use is prone to fever, serious power-down problems.
We will compare the Sony Xperia XZ and iPhone6s Plus photo proofs on the next page.
Photo proofs comparative analysis
In the process of camera experience, in order to more intuitively respond to the Sony Xperia XZ imaging, I use the iPhone 6s Plus in the hands of the comparison, the comparison chart released without any post-processing in addition to cutting, both phones are in automatic mode Shoot down. If you need proofs, you can post @Aliang dll.
Before the comparison needs to explain two things.
1, Sony Xperia XZ proofs are taken using 23 million pixel mode, iPhone6s Plus 12 million pixels, so the former has an absolute advantage in terms of resolution, while the latter because the pixels are lower, so the image processing, the algorithm is more rapid and stable .
2, from the author's own experience point of view, Sony Xperia XZ in the focus compared to the iPhone6s Plus has a clear advantage. In dark light or macro shooting, the iPhone 6s Plus often “pulls the bellows†so that a slight shake of the camera can result in inaccurate focusing or blurring. Thanks to the application of triple image sensors, Sony Xperia XZ has barely experienced this phenomenon.
Sample comparison:

From the above two comparison charts, we can see that the Sony Xperia XZ has a cool white balance when shooting outdoor scenes. This is most evident on the second map. Compared to the real scene, the proofs of the iPhone 6s Plus are closer to the original colors at the time. However, the photos taken by the Xperia XZ have more intense colors and higher saturation, and they are more appealing to the user's eye. However, the iPhone 6s Plus was overexposed when there was plenty of light outdoors, and the whole picture became very pale.

Macro proofs comparison (four)
In terms of macros, the performance of Xperia XZ and iPhone6s Plus is comparable. The strength of the Xperia XZ lies in the fact that the lens is capable of capturing a wider range of scenes with greater blurring power and better resolution. The iPhone 6s Plus has the advantage of being very stable in metering. After comparing several photos, we can find that Apple has more sophisticated and accurate control over the camera's various parameters.
Backlight proofs contrast
In the backlight conditions, iPhone6s Plus performance is very calm. HDR mode will be automatically turned on when taking pictures. It will not only clearly capture the clouds in the sky, but also the color of the pavilion's eaves. In contrast, Xperia XZ is significantly worse than the iPhone 6s Plus. Although the camera will automatically recognize that the camera is currently in the backlight conditions, the imaging results are still not satisfactory.
Indoor dark light proofs contrast
In the dark room, Xperia XZ appeared again in the beginning of what we said, and its color performance is a little too strong. Obviously, Sony is taking a range of artistic talents and can focus on the color performance of things. If you do not compare, you will feel that the photos taken by Sony Xperia are excellent. But in the end it is a good thing to restore the original color or try to please the user's eye is good, I can not assess the superior, it is still different from person to person.
Outdoor night proofs (1)
Outdoor night proofs (2)
Thanks to the excellent genes inherited from SLR cameras, the Sony Xperia XZ's rear camera's ISO performance has soared to 12,800. However, from the point of view of proofs, the 2500 ISO has also become obsolete. The entire picture is brighter than the iPhone 6s Plus. . However, too high an ISO can cause the sample noise to soar. In addition, the phenomenon of sky redness appeared in the Xperia XZ proofs, and it is hoped that Sony will improve this in future software updates.
Five-axis image stabilization comparison test:
In fact, in addition to the camera's triple image sensor, Sony's five-axis image stabilization is also a major feature. It can adjust the jitter of horizontal, vertical, rotation, horizontal rotation, vertical deflection through the algorithm, so that the recorded picture becomes more stable.
The following video, left for the Apple iPhone6s Plus, right for the Sony Xperia XZ (both phones are in 1080P, 30fps mode shooting).
It is easy to see that the performance of the Sony Xperia XZ 5-axis image stabilization is amazing. In the beginning of walking, the gap between the two is not obvious, but when running, Sony Xperia XZ's picture is still quite stable, and iPhone6s Plus has shaken very powerful. Unfortunately, this five-axis technology can only be used in Sony's own cameras. After testing the live broadcast software, it does not support five-axis image stabilization, and certainly does not rule out Sony's later adaptation. However, according to the usual practice of Dafa, this is almost impossible.
Comparison of photos
Sony Xperia XZ advantages:
1, the camera exhales fast, focusing speed.
2, sharp imaging, high resolution.
3, proof color saturation, especially red, green, blue three colors.
4, night proofs bright screen.
5, five axis anti-shake performance dazzling.
The lack of Sony Xperia XZ (only for 23 million pixels):
1, camera interface options are complex, easy to get stuck.
2, metering is not accurate enough, the degree of light and shade is erratic.
3, night sky is red.
4, backlight performance is more general.
After this experience, the Sony Xperia series has retained the camera key that has won my heart, and there is a feeling of using a card camera to take pictures. The Sony mobile phone camera still gives me a leading technology, optimize the feeling of lag. The imaging performance in automatic mode is good or bad. If you understand the camera and know how to adjust the parameters, you can easily use the Sony Xperia XZ to take good pictures.
