From one-eyed dragon to the three eyes of God | cell phone camera experienced what

There is a camera called Light L16, this camera has 16 cameras, so that intensive phobia scared urine minutes.Mobile phone camera is also moving in the direction of multi-camera, but not yet reached the metamorphosis of 16 cameras, double Photo has now basically achieved popularity, and we will also usher in the post-three camera phone.

It is reported that Huawei will hold a new conference on March 27 in Paris, France. The protagonist of the conference is the P20 series mobile phone with three pictures.

In terms of posters, the three O's seem to represent three cameras, the theme 'see mooore with AI' and the word 'more' into 'mooore' is more intriguing. Three shots there will be what kind of upgrade? The camera is really the better? Today we talk about the number of mobile phone camera thing.

We have seen the camera one two three

Abandon the basic functions of smart phones do not say that taking pictures seems to have occupied the first mobile phone accessory trend, camera phones have also become a major part of mobile positioning camera phone camera functions indispensable, the reason, in addition to the daily scan code and other functions Application, the biggest reason is that many mobile phone users are accustomed to using a mobile phone camera to record life.Based on the small size attributes and network platform, the convenience of taking pictures of mobile phones is unmatched by professional cameras.

The J-SH04, the first camera with a built-in camera, has been around for 18 years and perhaps no one has ever noticed that this 11-megapixel camera did not cause much turbulence at the time, Today there will be so many changes and upgrades. Now we look at these mobile phone camera, not only to see the phone camera has tens of millions of pixels, aperture, a few P lens, sensor type and size, OIS optical image stabilization, focus mode And so on, have become our concern.

The top cell phone single camera now has a very good shooting, but compared to professional cameras, there is a big gap because of the limited size of the miniature camera module, with the previous commercial assembly technology, almost impossible to achieve Aperture and focal length of the physical changes. So double camera began to play its historical role.

Initially the most widely used dual camera is to simulate the shallow depth of field effect of a professional camera large aperture, through dual-camera parallax and algorithm processing, pull the focus of the main subject, the background blur .This is basically the first one a pair of double camera program Have all the new features.

Later, there also appeared a wide-angle + a telephoto and a black and white + a color of the two double camera program.The improvement of these two programs is that both can achieve dual-camera zoom, the former through double camera switch, the latter In addition, as the latter in the shooting work, the color and black and white camera will capture the image at the same time, the final synthesis by the algorithm output as an image, so the image quality will also be improved.

After that, we also saw a new double camera program, this program has no difference in the focal length of the double camera, but the two lenses have their own strengths.The shooting system will be based on the shooting environment automatically select the appropriate lens Shooting. The benefits of this program is that you can make the phone shooting suitable for more shooting conditions.

Speaking of three cameras, appeared on the smart phone really, that is Google Project Tango several AR cell phones under the project.Of course, here's three shots in the cell phone camera quality improvement is not helpful.

Mobile phone camera really better the better

More and more facts and rumors seem to point to such a conclusion: the higher the number of mobile phone cameras, the higher the shooting level, and according to this logic, it is not impossible for a 16-lens camera like the one mentioned in the text to appear on a future smart phone. Really? Mobile phone camera will really be more and more direction?

It is undeniable that the multi-camera does bring us a lot of mobile phone camera can not be achieved single-function: a large aperture of the shallow depth of field blur effect, a more diverse shooting environment to adapt in theory, what you want to shoot phone good at , On the phone plus a dedicated camera for this area shooting, full-time use, so that users can meet the more specialized needs of the phone shooting.So, the possibility of seeing more lenses on the phone is not Absolutely not.

Take now basically popularize the current double camera, telephoto + wide-angle lens combination to meet our needs for two different physical focal lengths; different functions of the double camera through the smart lens switch, you can use to shoot high brightness of the location , You can also shoot a very dark night light; the color of the most black and white + color lens combination, not only can achieve zoom, you can get higher image quality.

When this kind of program dual shooting shooting work, the color and black and white camera will take pictures at the same time.Because the black and white camera canceled the dichroic filter, so than the color camera has a higher amount of light, the image details will be more clear After the two images are fused by software, you can get a clearer picture than a normal color camera, this sharpness enhancement effect is particularly obvious when shooting at night.

In addition, this program dual-camera zoom zoom is achieved on the basis of high-resolution black and white cameras.With one of the Leica dual camera for Huawei mobile phones, when shooting a zoom photo, 20 million black and white camera is responsible for shooting Out of a high-definition black and white images, and then cut off from this image out of the 12 million color camera shooting the image range, the software and color images by fusion, resulting in a higher quality zoom image, which is also the highest resolution Rate can not be caused by non-destructive zoom.

Therefore, the multi-photo can really bring more excellent shooting experience to the phone, but then have to come back, double the reason why there can be advantages, because a large number of mobile phones with the micro-camera module technology and technology Assembly is not advanced, making it difficult to compare with a professional camera.If these problems can be solved, the camera will lose the meaning of existence.For example, we see the Samsung W2018 physical variable aperture camera, variable aperture appears Let the phone double lost half the meaning of existence.

However, for the moment, there is still a long way to go to get closer to a professional camera with a mobile phone, and this process is exactly the spring that many cameras are breeding for.

So what is the use of a camera out of Huawei P20? Personal speculation that if the camera is to increase the level of camera to enhance it, then there are two possibilities: First, add a special lens for macro shooting, the reason is that Double shot algorithm is difficult to do is not bad, complicated scene difficult to achieve precise cutout intersection, then the special macro lens there is the value of existence; Second, the large pixel camera through a larger pixel black and white lens, three shots Module can achieve higher pixel image capture, support for more than one focal length of the dual-camera zoom.

Huawei is also not allowed to trip a trip to the tide of AR

In the first part, we mentioned Google's Project Tango project. Unfortunately, next month, Google will stop this project to continue to use less demanding on the hardware camera platform ARCore. Admittedly, Although Project Tango has a high demand for camera modules, the real-world enhancements are even more in-depth. A handset supporting this AR technology requires three rear cameras.

And the three cameras have different functions and not every one is used to take pictures - a depth-sensing camera is used to measure the depth of the environment, a motion tracking camera is used to aid in device positioning, and an ordinary camera is used for real scenery Shoot.

Depth perception is not a strange concept right now. The 3D structure of the iPhone X facial recognition is a type of depth perception. Of course there is a TOF solution that obtains the depth by inversely calculating the time difference of the infrared ray, and the depth perception by the dual camera disparity Binocular stereo vision technology through depth perception, the mobile phone can get the depth information of the surrounding environment, which provides the data foundation for the establishment of the environmental 3D model.

Inertial measurement unit, accelerometer and gyroscope and other sensors can detect the movement, but there are cumulative errors, this time you need motion tracking lens (wide-angle fisheye) for continuous shooting of the environment, by the relative position of the feature points to calculate the movement distance , Thus eliminating the error of the trajectory.

The depth and relative position are determined, and the augmented reality image can be obtained by combining the virtual image synthesized by the software with the actual scene photographed, so that the AR technical solution can obtain more accurate realistic augmentation effects and have a broad market in future scene applications , Such as real-time map navigation, indoor navigation, indoor environment modeling, furniture, home appliances, etc. The resistance lies in the complexity of the hardware support required for this AR solution.

Therefore, Huawei's P20 series of three cameras, if not for enhancing the shooting effect, then it may also be Huawei started to force in the field of AR.However, the Project Tango program less likely, after all, Google is about to suspend the project. But then again, it is not entirely impossible for the AR system to be supported by Huawei's technical strength.

Write in the end

Therefore, we will see three shots on the Huawei P20 series models. Most likely, we will add a more specialized lens to the camera to meet the shooting needs of more scenes on the basis of the original two-shots, or develop Three shots AR also have a certain possibility.

In the more distant future, if single-camera technology is still hard to break the technology bottleneck, then we are more likely to see more and more cameras on the smartphone, so friends with intensive phobia may suffer.
