Third generation mobile phone photography

Last September, Samsung released the third generation 1 100 megapixel sensor HM2. The size of the sensor is11.52 inch, and the unit pixel size is 0.7 μ m. ..

Not long after the release of this sensor, Red Rice Note 9 Pro was officially released. Redmi launched this sensor in the Note series and has always been known as a "cost-effective machine".

In the last two months, Glory 50 Series and vivo S 10 Pro have been listed one after another, and both of them are equipped with this Samsung HM2 sensor.

So what kind of differences will the same camera sensor show in the hands of models with different configurations from different manufacturers?

Today, let's put aside the auxiliary camera and fancy image function and see how the main cameras of these three models perform in taking pictures.

Daytime shooting

Generally speaking, in order to take into account the size of the image, the default shooting will not directly produce a picture of 65.438+0 billion pixels. Samsung HM2 adopts the technology of nine pixels in one, that is, the size of a single pixel is equivalent to 2. 1μm, and then the synthesized default output image size is12 million pixels.

Next, make a sample. The photos from left to right are Red Rice Note 9 Pro, Glory 50 Pro and vivo S 10 Pro respectively. If you forget the order, you can also see the watermark in the lower left corner.

Judging from the first set of proofs, it is probably because the processor performance of vivo S 10 Pro is better than the other two models (Tianji 1 100), and its performance in details is also slightly better than the other two models.

In addition, the lighting performance of vivo S 10 Pro is softer in the highlight suppression in the upper right corner of the picture.

In terms of color performance, Glory 50 Pro is the best in reproduction, and the color richness and white balance of the shooting picture are better than the other two models.

In contrast, the color of vivo S 10 Pro is more stylized, and the slightly yellow film looks like a faint oil painting filter.

Moreover, vivo S 10 Pro will also increase the exposure of the overall picture by one step, making it look brighter and more transparent. Doing so under the premise of proper highlight control is also a small skill to enhance the impression.

The performance of red rice Note 9 Pro in color is quite erratic. In the case of comfortable ambient light, the red rice Note 9 Pro improves the color saturation, which is simply "too bright".

There are obvious bright spots in the background, such as lights and strong lights. The red rice Note 9 Pro will have a certain atomization phenomenon, and the picture seems to be covered with a faded trace.

Multiple zoom

Because the cost of 1 100 million pixel sensor is relatively high, Red Rice Note 9 Pro, Glory 50 Pro and vivo S 10 Pro are not equipped with optical telephoto lenses in the image module. Therefore, the responsibility of multiple zooming naturally falls on the main camera.

Samsung HM2 sensor itself has the characteristics of 3 times lossless zoom, so the details of the three models are not much different within 2 times.

1 verification

Double proof

Under the imaging of more than 5 times zoom, the details of the three models began to appear gap. The picture of red rice Note 9 Pro has obvious noise, while Glory 50 Pro is the best of the three, followed by vivo S 10 Pro.

Five times proof

10 verification times

In this way, the multiple zoom of the glory 50 Pro is indeed the "tall one" among the three models.

However, I can't say any more. The Redmi and vivo of the house operate vertically when zooming at multiple times, and the right thumb completely controls the zooming and presses the shutter in one go.

Glory zoom operation is placed horizontally at the bottom of the interface, so it is not so convenient to operate with both hands.

It is true that when the maximum magnification is more than 30 times and 60 times, the horizontal zoom can bring more operating space and zoom more accurately. However, for a model with the highest zoom factor of only 10, such as Glory 50 Pro, the horizontal zoom operation is somewhat awkward.

High pixel mode

If you want a single photo to have super high resolution, you can turn on the "high pixel mode" and let the mobile phone directly output the image of 1 100 million pixels.

It should be noted that the high pixel mode requires more computing power when shooting and imaging, so the time from pressing the shutter to finally outputting photos is related to the performance of the mobile phone.

From the actual experience, vivo S 10 Pro is the fastest, followed by Glory 50 Pro, but the two are almost the same. The slowest is the red rice Note 9 Pro, about 2 seconds at a time.

Let's look at the imaging performance.

Red rice Note9Pro–1100 million pixels

Glory 50 Pro- 1 100 million pixels

Vivo s10pro–1100 million pixels.

From the actual imaging point of view, the details of Glory 50 Pro and vivo S 10 Pro are at a satisfactory level after multiple magnifications, while the red rice Note 9 Pro may be limited by the performance of the processor, and there are more noises after cropping and magnifying.

Night scene imaging

Come to the night scene part. As mentioned above, Samsung HM2 has achieved the equivalent effect of 2. 1μm per pixel through the nine-pixel synthesis technology, which also means that the imaging in the dark scene is more pure and delicate.

Coupled with dual native ISO technology, it automatically switches to high ISO mode at night to ensure high-quality shooting level.

In the default mode, the night scene performance of the three models is different.

The first is vivo S 10 Pro with a series of night scene algorithms. Vivo has always been solid in the night scene algorithm, but with the blessing of Samsung HM2 nine pixels in one, the night scene performance is excellent.

In addition, vivo S 10 Pro's consistent image processing method of "forcing highlights+improving image brightness" makes the image look pleasing enough.

Although glory 50 Pro is slightly weaker than vivo S 10 Pro in night view, highlight suppression is a weakness. However, the dark details and the overall performance of the picture on the horizontal line are still satisfactory and commendable.

Red rice Note 9 Pro may be limited by performance, and the dark details are basically lost. However, the highlight suppression is well done, which is also a little score.

After the night scene mode is turned on, the mobile phone will absorb more light information by extending the exposure time, thus reducing the highlights and increasing the details of the picture.

In this link, vivo S 10 Pro goes further on the basis of its original good performance.

Glory 50 Pro extends the exposure time to about 4 seconds, which is the longest of the three models (vivo S 10 Pro is within 1 second, and red rice Note 9 Pro is within 2.3 seconds).

It is precisely because more light information is obtained that it has advantages in processing. Glory 50 Pro is also the best contrast between light and shade.

After turning on the night scene mode, the imaging performance of Red Rice Note 9 Pro has improved a lot. However, in the case of more light, atomization appeared again, and the dark part turned white.

And what has to be spit out is that both vivo and glory put the "night scene mode" in the first-level menu of the camera interface, which can be opened with one button; Redmi, on the other hand, puts the "night scene mode" in the secondary interface, so it is quite tedious to click "More" before clicking "night scene mode" when opening.

Originally, shooting night scenes in the default mode of Red Rice Note 9 Pro was not excellent, and the "night scene mode" was hidden by a layer, which was somewhat unreasonable.

abstract

From the appearance of the concept of 100 million pixels in mobile phone photography to the present, the debate about "right or wrong direction" has never stopped. But children argue about right and wrong, and adults only care about whether it works.

The location of the mobile phone imaging system is so large that no matter how much material is piled up, professional cameras are hard to match.

Therefore, how to create a beautiful shooting experience through the deep cooperation of hardware and algorithms is one of the key issues that mobile phone manufacturers need to consider when polishing the image system.

1 100 million pixels need enough processor performance support and hard-core algorithm to lay the foundation for imaging effect.

I am not against "100 million pixels", but if we blindly pursue high pixels and ignore the actual use effect, I can hardly say that this direction is right.
