Not so long ago in the network appeared the news that now there is a camera with a resolution of more than 100 MP. Such abrupt changes in the characteristics of components of a smartphone was not very long ago. Only here is it necessary or is it another useless feature for feature? One of those that allow you to sell even a relatively mediocre smartphone, but with killer features. Sounds well and good, but why you need such a permit, really? And need whether.
How to free phone memory
Suppose, for example, are the camera will really make the resolution more than 100 Megapixels. What’s next? This resolution must match the amount of internal memory. For example, in my library for many years, have accumulated about 30,000 images. If I deflate them to the memory of your smartphone, from my 256 GB is free space. And all this in a camera with a resolution only 16 MP.
In addition to the resolution of the photos, claimed that the novelty from Samsung will be able to shoot video at a resolution of 6K. There are issues even more. On the one hand, the high resolution helps when creating a video, on the other hand, even 4K on a smartphone is so-so entertainment. A lot of noise, lack of detail at the slightest deterioration of lighting and many other restrictions.
One thing is for sure, the question of memory in relation to the video is not so acute. Typically, everything is removed even in 4K in the near future after the completion of the shooting time is sent to computer or archival storage. This is not surprising, because one minute of video in 4K takes up about 500 MB. It is not logical to accumulate such amounts to the internal memory of the smartphone.
Here, by the way a little advice. Just check did you take video in 4K and don’t lie whether they are in memory. I was such. Didn’t notice that was running in this mode, and took a lot of memory, and then sought how to release.
Why the cameras do not improve
At the time Steve jobs said that users do not know what they want. He believed the responsibility of the manufacturer to tell them about it. Over time, his words becoming more clear. As at the time we ”took” a bunch of push-button phone and PDA, giving in exchange the smartphones, so now we need to give not just the increase in megapixels and the breakthrough, or at least a new vector of development.
The direction in the direction of increasing resolution in a wider context. The number of megapixels has become the main measure of the quality of the cameras in the understanding of the end user. A similar situation can be observed with a diagonal TVs, power cars and many others. It is successfully cultivated, and manufacturers are beginning to measure themselves know what exactly this figure. That’s just all forget about such parameters as, for example, light intensity for cameras, the quality of the matrix for TVs and torque for cars.
To blame in this situation nobody. Most buyers are not skilled in technology and have sometimes too complicated, technical knowledge, and manufacturers want to earn, not to invest in a confusing for the end user of the technology. Instead, advertise a good, but not the most important improvement.
Is it bad to have a high resolution camera
Overall, there’s nothing wrong with that resolution of cameras is growing and manufacturers have learned programming methods to combat the drawbacks of this direction of development. The main disadvantage is the increase in noise in the picture. But even ”cleaned” by the software.
Many manufacturers are doing this very successfully, and modern high-performance components smartphones good at it. In the end we get a clean enough image for such a small sensor, which is installed in the smartphone.
What will the camera of the future
First and foremost, it is necessary to understand what appear on the picture noises, which we should fight software.
The matrix of any camera is composed of sensitive cells that can read the light falling on them. On top they are covered with filters of red, green and blue colors (Red, Green, Blue — the RGB). Through each of these filters passes only one color combination and gives the camera understanding light is what color fell on each photosensitive cell. These cells are the most pixels. Accordingly, the number of megapixels of the camera is equal to the number of millions of such cells on a tiny sensor, the size of which hardly reaches a few millimeters.
For a deeper study of the question: How does the camera of a smartphone
The location so close points (distance between them is measured in micrometers), and even in such numbers is already leading to what appear on the final picture interference and noise. If the camera software understands that in a particular place the picture should be, for example, the sky, it removes many small colored dots (noise) and making the image more homogeneous. In modern conditions to this and should be sought by manufacturers of cameras, smartphones and not to the removal of the original sensor information as it is trying to do some of them.
A little further than the others in this issue have advanced the engineers at Sony (at least they say so). To improve the quality of the final picture, they go a little different route. Usually, after removing the data from the sensor is formed of the JPEG file, which is processed by the processor. In the latest Sony models in the processing is the file in RAW format, which contains considerably more detail and information about the image. After processing and noise reduction, it is converted to the final JPEG.
This approach has advantages, but Sony really tries to keep the level of interference images at a minimum. Except, as mentioned above, this should leave, because it’s not a SLR where the sensor size is ten times more.
Hence, we can conclude that the processing of the finished images is certainly good and not evil, but the size of the matrix should not be forgotten. It may slightly change the thickness of the smartphone as the larger sensor will require a processing optics, but work in this direction is necessary, and some manufacturers forget that.
However, we must pay tribute, the new sensor from Samsung, which we mentioned in the beginning of this article, the area of the sensor is increased. However, only in order to place a new millions of sensitive cells or, in simple language, megapixels.
The stages of development of cameras
If we talk about smartphone cameras, I would note a few highlights that can be called a qualitative leap, not just improvement. You may not agree with me, but here they are:
- increase resolution up to 12 MP
- the emergence of optical stabilization
- the appearance of the second module
- video recording in 960 fps
The first and second paragraph of questions, I think not. Further development permissions is already a whim, and optical stabilization is often useful if it is not prone to errors.
The presence of the second, third and subsequent modules, allows in a small package implement a zoom, but the manufacturers are often used in these minor modules more simple sensors. Sometimes, this leads to the fact that digital zoom photos were taken on the main module, allows to achieve better results than a separate module with ”optical” zoom.
Video with a frequency of 960 frames per second is more of a toy, but very interesting, and it is a pity that the manufacturers pushed the development of this technology in a drawer. For the complete implementation of this function needs fast memory, as the flow of information is very high. The main memory device can not work with such speed, and the camera module is inserted into a separate chip which has a very small capacity, but very high write speed. At him and being shot, and when it is completed, the information is transmitted relatively slowly on the main drive.
Now in this way it is possible to remove just a fraction of a second of video, which then turn into a few seconds of the final video in slow motion. It would be great if the manufacturers have increased this time at least several times.
Camera new generation
Everything I said above is a personal opinion built on some facts about the development of technology. Now let’s talk about what would be a good idea to use cameras in smartphones in the near future. Again, opinion is subjective, but to discuss this in our Telegram chat. There will always be someone to talk about it.
In the first place, in my opinion, need to stop chasing the camera’s resolution, to stop at the level just above 20 MP, and concentrate on increasing the size of the sensor. This leads to the fact that the smartphone will have to make fewer changes when processing the image, which will automatically affect its quality.
As a second change I would suggest working on increasing intensity and brought this parameter to main, so that people can see it inscribed in the specifications and not just the resolution.
The third item I would have revived the work on shooting verzameling video. They look interesting and allow you to literally see the moment. If it is good to work on this feature, it will cease to be just a toy. In the end, it’s significantly more interesting than the 120 fps 240 fps.
In addition to the above changes, I would suggest all smartphones to do the normal disable image stabilization. The fact that it now turns off very badly and because of the suspension module and jerky even when shooting with stabilizers like OSMO Mobile.
The last time I would cautiously called for further work on improving the software processing. She is good, but no limit to perfection. However, you should not make a cult of it.
What else can be improved in the smartphone camera
I do not claim to absolute rightness of his opinions. I, like everyone else, I don’t know what should be a revolution in mobile photography. If I had known, I would have promoted this idea and was about to get rich. I’ve simply offered their vision of the evolution of cameras. At the same time, the frontalka I don’t have a large number of questions. With its task it quite well. That’s just under the screen it somehow necessary to hide.
At the moment, the smartphone camera is needed in order to get the device out of your pocket, take a picture and get him back. For something more carry a separate camera. Manufacturers convince us otherwise, but it is not necessary to believe it. Full the camera will still be able to do more, and it is pointless to argue. Otherwise, why professionals are buying a pricey camera, if everything is as good as smartphonetoday show in their commercials?
Let the camera of the smartphone is not up to Pro-solutions, but that’s okay. Just not worth chasing numbers. This is the wrong direction.
