This is the original reason why HTC and Sony do not do the double

Every time a smart phone brings a 'makeover' of innovative technologies, it will be appreciated by other consumers because every innovation means the development and advancement of digital products in the field of technology. For example, the full screen in 2017, such as 2016 The beginning of the popular dual camera.

Mentioned double shot, presumably we have long been commonplace.No matter the iPhone or Android lineup, most of the recent flagship have adopted a dual camera design, the reason is very simple, more than one camera is used to enhance the phone imaging However, still There are new machines that retain the 'single' design descent, such as the Sony Xperia XZ1 and HTC U11 +. Today, we will test both of these single-image flagship models to see if their single-camera imaging qualities can withstand the dual-camera trendsetter Come and have a taste of it.

First look at the camera configuration of the two phones:

The talk is a rear camera problem, so the front configuration for the time being not considered.Post, HTC U11 + is equipped with a 12 million CMOS sensor, the main aperture of f / 1.7, Sony Xperia XZ1 is equipped with a 19 million CMOS sensor, the main aperture of f / 2.0. First of all for the aperture size, HTC U11 + dominant, because of its aperture larger, in terms of pixels, in theory Sony Xperia XZ1 sensor larger, better imaging.

Photo features, HTC U11 has enough bright spots, using the 3rd generation UltraPixel is particularly dazzling.Familiar with the HTC mobile phone friends all know, UltraPixel is its unique camera technology.First of all we all know that the camera is good or bad and the pixel size does not matter, one of the factors that determine the imaging is good or bad The size of the sensor. (The third time in the text that this thing)

Photosensitive components literally, and the light is related to the quality of the image depends on the number of photons captured by the photosensitive element to determine the larger photosensitive elements can capture more photons, the better the photosensitive properties, can bring more delicate Of the picture quality, the higher the resolution naturally.While why the number of pixels and picture quality has nothing to do?

Here, the photosensitive element can be understood as a carrier for carrying pixels, There is a pen that can write ten thousand words, write it on a small business card, very crowded, and write it on a sheet of A4 paper, very spacious. The larger the carrier, the better the performance. Similarly, writing on two sheets of A4 paper, the words are extremely large and can not be written much. On the contrary, the characters are very small and can be written very much. The words are relatively crowded with each other. Pixels are also the same. With a fixed area of ​​the sensor, the higher the pixel size, the smaller the pixel size. In theory, the larger the image noise, the smaller the dynamic range, and may be affected by the circle of confusion. That is, the mutual influence between pixels.

On the contrary, the larger the pixel size, the better the noise and dynamic range of the image can be controlled, and also less affected by the dispersion circle.Apple has been using 800W low pixels, a big reason is to maintain a large pixel size .

For another example: A total of 100 people living in a 50-square-foot cottage, very crowded, living in a large 8,000-ping castle, very comfortable, both houses can accommodate 100 people, if you want to literally ' Can live a hundred people's house 'can not judge the size of this house.

This is why the 800W pixels of the apple take photos better than the other 1200W pixels phones, the 500W SLR like to kill the 1600W mobile phone camera, a great reason is because of its house (sensor) is large, and it lives in the (pixel Large enough fat enough to hold up the house.

Back to HTC developed UltraPixel, you can understand that it is the size of each pixel is enlarged technology, HTC UltraPixel camera size of a single pixel reached the maximum 2μm. And the general use of most 13-megapixel smartphone 1.12μm , The pixel area (4μm) of the 2μm pixel of UltraPixel is more than 3 times that of the ordinary cell phone (1.2544μm), that is, the amount of light per unit pixel can reach 300% of that of a normal 13MP pixel smartphone Compared with the mainstream flagship, the same pixel size, apparently using UltraPixel technology, mobile phone sensor larger, better imaging 2017 UltraPixel has evolved to the third generation, and it is clear that this technology ushered in its full form.

Come take a look at Sony, Sony Xperia XZ1 still will Motion Eye ™ camera stacked memory chip sensor as one of the biggest selling point of this generation.What technology is in the end? Allow me three minutes for the students do not understand to explain. To put it bluntly, this is Sony's innovative technology in the CMOS structure. We all know that today's mobile phone camera sensors include the traditional, back-illuminated and stacked three types, now commonly back-illuminated and stacked CMOS structure.

From a structural point of view, the stack CMOS is a new upgraded version of back-illuminated CMOS, with high pixelization, high performance and miniaturization features can be seen from the picture, whether it is back-illuminated CMOS or stacked CMOS It's two levels, and Sony's Motion Eye ™ camera stack memory chip sensor innovative three-tier stacked, the core of this sensor is the pixel layer and the signal processing circuit layer by adding a layer of DRAM cache to form a sandwich structure.

In other words, on the basis of the original added a 'DRAM cache There is a friend to ask, this DRAM cache is doing? Editor to tell you, it is mainly available 'Super' slow motion capability, the official claim that this can provide the Sony mobile phone so far the most powerful slow-motion shooting capabilities.

Yes, the three-layer stacked CMOS sensor can continuously read 120 193-megapixel still images (four times more than before) or 1080p at a frame rate of 960fps / 1000fps (eight times more than regular sensors) , To achieve real super slow motion playback. Let us feel:

From 960fps super slow motion Is not it cool, despite the quality of a little residue.It can be said, whether it is configuration level, or technically, for example UltraPixel third generation technology HTC U11 +, Sony's Motion Eye ™ camera stack memory chip sensor, these two single-shot flagship in the field of photography have enough bright spots and compete with the dual camera.

Camera interface, the two flagship continuation of their own brand characteristics of the operating mode: HTC U11 + down on the top out of a variety of modes of interface; and Sony Xperia XZ1 is sliding around the switch mode, more settings, click the Settings button in the lower left corner of the screen when taking pictures, Sony The Xperia XZ1's unique Auto-Recognition scene has a unique small icon and tracking focus 'object tracking' mode is also very rare in flagship, which also matches the selling point of its flagship video capture.

Not much gossip, look at proofs contrast:

Test process to turn off the HDR, only standard mode shooting during the day, despite the cloudy days, the two mobile phones still show a clear and sharp picture, 100% magnification was observed Sony Xperia XZ1 reserved for the details of the rich, HTC U11 + seems to be more good at shooting dark things, the proofs presented brighter.

When shooting more color things, Two mobile phone resolution is still good, subtle observation can be seen, HTC U11 + slightly higher color saturation, more vivid and bright color to teach.

Indoor environment is relatively weak light, but also more complex, so it is to test the phone's weak light imaging and anti-shake performance observed sample can be seen that the two mobile phones less deviation in white balance, taken proofs are relatively close to the human eye to see The scene, Resolution more than during the day and also No loss It seems Sony Xperia XZ1 lighting and other shiny things have a unique algorithm skills, shooting lights than the HTC U11 + is more pure, and halo control is not bad.

When shooting things Sony Xperia XZ1 has inherent advantages, it automatically identifies the scene features can be detected at any time to optimize the environment, you can see the Sony filming things more vivid, beautiful, look more pleasing to the eye. In addition to color reproduction and light control, Sony Xperia The XZ1's expressiveness is flagship, with a 19-megapixel lens that easily captures the rich details of flowers and leaves, magnifying to see clear, rich petals.

Although it is a single camera, the two phones can still shoot the bokeh of the macro map, 100% enlarged can be seen, the two mobile phone cutout more accurate, and dual camera imaging almost the same.It is worth mentioning that, Sony Xperia XZ1 stored after the proofs sample memory more than the HTC U11 + 1 ~ 2M, the same format in theory the same memory, indicating that the pixel is high, the details of the film richer SLR camera raw format accounted for a lot of memory, because the ratio The jpg compression format retains more details.

In addition, the test editor also found a problem that is taken during the shooting frame is obviously HTC U11 + imaging better, Sony Xperia XZ1 showing some paste the scene, but after the filming found Sony Xperia XZ1 sample is still quite clear, for which the editor made a special experiment: first open the camera interface facing a book, manual focus does not shoot direct screenshots.

As you can see, the Sony Xperia XZ1 has been out of place. Let us look at the comparison proofs after clicking shoot.

Although the resolution of both mobile phones even though the same, after amplification are very clear and visible why this happens, I do not understand to explain to the students:

First of all, the principle of the camera is the lens lighting, the workflow of taking a photo is the sensor to convert photon elements into electronic signals, and then the image processor to convert the electronic signals into human-visual image files, while the viewfinder to see Just taken pictures of the lens, so no matter what kind of viewfinder, the viewfinder screen and the actual picture are different.

Second, why the difference between Sony mobile phones will be so big? Editor's guess is better than software optimization is not in place, although Sony's hardware is excellent, but the distance from the WYSIWYG imaging optimization, apparently other mobile phone brands to be more mature.

to sum up

Why HTC and Sony did not do double shots, as Kiyama Yosuke, Sony senior mobile product manager, also said before, 'At present a lens is enough to bring a high-definition experience, Sony is also willing to single-shot to the extreme.'

Besides HTC, as early as March 2011, HTC launched a pair of camera phones that support the naked eye 3D technology, then the double camera technology, is to shoot 3D photos and 3D video, it can be said that HTC is the ancestor dual camera manufacturers. That it Why not use dual camera, but with a single camera made the world's best mobile phone products? Editor's guess one of the reasons may be that HTC's dual camera technology, which seems to be trapped in the decline in the performance of mobile phones , Unable to do a new dual camera research and development.Current HTC was Google acquisition, the future will launch dual camera products we do not know.It is worth mentioning that the internationally renowned digital camera quality measurement site DxOMark, the current smart phone The first photo-taking Google Pixel 2 is a single camera phone.

After reading the proofs of the two mobile phones, we are also very clear about the comparison. Whether it is HTC's third-generation UltraPixel or Sony's world's first three-layer stacked sensor, the software optimizes the imaging of the mobile phone without losing the double- It is the software optimization, before the single camera has the power to contend with the dual camera, whether it is single or double camera, we are eager to see smarter camera better performance.
