Whose cameras are in iPhones. iPhone X main camera specs. Improved face detection

Do you use your iPhone to its full potential when you take pictures? Some of the program's features are hidden so deep that you either don't use them or don't even know they exist. In this article, I will describe 9 opportunities that the iPhone provides to aspiring mobile photographer.

Quick access to the camera

How often in real life Do you see a funny moment and want to take a quick picture of it? Yes, all the time! The fastest way to access the iPhone camera is to swipe left on the lock screen. The camera is instantly ready for use. You don't even need to enter an unlock password.

But what if you are already using a smartphone or suddenly it was instantly unlocked via Touch ID? While in any application or on any desktop, swipe up at the bottom of the screen, you can call up the “Control Center”. There you need to tap on the camera icon. Everything - the camera is ready to use!

Use a grid

The grid when shooting is two horizontal and two vertical lines that divide the frame into 9 equal parts. When photographing, always pay attention to the grid. Remember the "rule of thirds".

The rule of thirds is a compositional principle based on simplified rule golden ratio. Below is a picture taken based on this principle. As you can see, the horizon line coincides with the lower horizontal line. It is believed that the horizon in seascapes should be done along this line. The tree is located at the lower right intersection of the lines. Everything seems to be true, although objects in the singular are still recommended to be placed in the lower left intersection of the lines, because the eye “reads” the picture from left to right.

But that's what the rules are, to stick to them, but sometimes break them. What is the conclusion here? The grid is a good helper for creating a great photo, but photography is creativity, so get creative!

Settings->Photo & Camera->Grid. This is where you can turn this option on/off.

Burst shooting

The iPhone has burst shooting. To do this, press the shutter button and hold for at least 0.5 seconds. Photos will start to be created from maximum speed and sharpness. Then in the Photos application, you can select a good shot (the series fall into a separate album), and delete the rest.

Cool selfie without hands

Most often, smartphone owners take selfies with the front camera, holding the iPhone at arm's length. But what if you want to take a better picture or take a picture of yourself from above / below / from afar? You can call on items that are at hand to help: for example, put your iPhone in a mug and ... quickly take the right pose to use the delayed shooting.

For those who need a more reliable device than a mug or a stack of books, I recommend paying attention to special tripods for the iPhone. For example, a very worthy choice at photosklad.ru.

Delayed shooting - clock icon on the photo screen - 3 seconds or 10 seconds.

Setting focus and exposure manually

Focus allows you to focus on the subject, make it as sharp as possible. In most cases, the iPhone does a great job, that is, autofocus works. But if you want to focus on a less obvious object, or just make sure that the object is in focus, then you can set this focus manually. Tap on the desired place on the screen and the focus will move there.

Exposure refers to the brightness of a photo. If you think that a potential photo on the screen looks too dark or vice versa too bright, then you can manually adjust the exposure. To do this, tap quickly on the focus of the image, and then to the right of the square that appears, you can increase / decrease the exposure using a special slider.

Locking focus and exposure

If you hold your finger in any place, the focus and exposure will be fixed at the current settings. What is it for?

I will highlight two options:

a) If you are determined to photograph an object from approximately the same position several times, slightly changing the conditions in the frame. I took a picture - put the phone down, changed something, picked up the phone again ...

b) If you plan to take a photo or even a series of photos where there will be moving people or objects in the frame. You fix it and wait until the object you need appears in the frame. If you do not fix in advance, then autofocus can ruin everything.

Taking pictures with the HDR function

HDR (high dynamic range) is another tool that's built into the iPhone's camera. The iPhone automatically turns on HDR if needed, but there's nothing stopping you from doing it manually. To turn on HDR, just press the corresponding button at the top of the screen. HDR is a technology in which the phone takes a small series of three shots with different exposures, and then combines them into one frame, which can be considered a properly exposed image.

Thanks to HDR, professionals can get very effective shots.

HDR is recommended if you are planning a frame that will have both bright and dark areas. Most often it is used for landscapes and scenes where the sky takes up most of the picture. The image is more detailed.

Settings->Photo & Camera->Keep Original. This option allows you to leave a normally exposed photo in addition to the HDR shot. I recommend turning this option on, because often a picture without HDR can be better than with it ... Use this option wisely.

Photo of volume button

Surprisingly, not everyone still knows that photos in the Camera application can be taken with the volume button, and any of the two. Also, if you hold one of the volume buttons, burst shooting will work.

This is useful given that it is the most convenient way. Try it. On one side, the thumb of the left hand reaches the volume button, in the other, the index finger of the right. Also, thanks to this life hack, you can take pictures with one hand.

LivePhotos - live photos

If your camera allows (you have an iPhone 6S, 6S Plus or later), you can take Live Photos. At their core, these are small three-second videos. Live photos are especially good for shooting some moving objects, the movement of water, some short jumps... They are also great for shooting in which sound will be a good addition to the frame: for example, the sound of a waterfall or birdsong...

Geotagging

Geotags in iOS are enabled by default and are assigned to absolutely all photos. Geotags let you know exactly where a photo was taken, which can be viewed in the Photos app. Also on a special map in Photos (unfortunately, Apple maps are used) you can see pictures from any area where you have been.

Apple does not spoil users with the exact technical characteristics of its products, believing that they do not need it. Instead of dry numbers, marketers prefer to focus on the merits, software capabilities of apple devices, their superiority over competitors. The iPhone X was no exception: at the presentation, attention was paid to the portrait mode, improved features, but many parameters were left behind the scenes.

Apple's official website contains some iPhone X camera settings, but the description there is incomplete. An analysis of the information available on the Internet helped to collect more details about the characteristics of the main camera of the new flagship.

iPhone X Main Camera Specifications

The camera on the iPhone X has received a cosmetic upgrade from the camera on the iPhone 7 Plus. The smartphone has a sensor manufactured by Sony of an unknown model. It traces its lineage to the IMX315 matrix used for the first time in the iPhone 6S.

The iPhone X camera matrix has a size of 1 / 2.93 ", which in the metric system is equal to a diagonal of 6.15 mm. The pixel size is 1.22 microns. The full resolution is 4032x3024 or 12.2 megapixels. It supports phase detection autofocus.

The matrix is ​​equipped with optics with an aperture of F / 1.8, FFR (physical focal length) 4 mm and EGF (equivalent focal length) 28 mm. The physical pupil diameter is 2.2 mm. There is OIS - optical image stabilization system.

Specifications of the second camera iPhone X

The second camera of the iPhone X is almost terra incognita, there is less information about it than about the main matrix. But something still managed to be found, for example, it is known that the matrix has a size of 1 / 3.6 ". This is equivalent to a diagonal of about 4.5 mm in the metric system, that is, the matrix is ​​​​smaller than the main one. The pixel size is 1 micron The full resolution of the iPhone X second camera is the same as the main one, 4032x3024 or 12.2 MP.

The optics of the auxiliary camera is a telephoto lens with an aperture of F / 2.4. Its FFR is increased to 6 mm, which corresponds to the EGF of 52 mm. Calculations say that the physical diameter of the pupil is 2.5 mm. Thus, despite the smaller aperture number, the lens of the second camera in theory captures more light than the optics of the main matrix. There is evidence that the second sensor is also equipped with an OIS system.

For shooting in low light conditions, iPhone X has a 4-LED flash with different color temperatures. It supports the Slow-sync function for better selection of the duration of the light pulse when shooting.

iPhone X camera features

The iPhone X camera is one of the best on the market in 2017. It provides very high (by the standards of a smartphone) photo quality and has a number of interesting features. The most notable feature is the 2x optical zoom. It is carried out by switching between sensors.

Since the second camera is equipped with longer focal length optics, its lens has a smaller field of view but the same resolution. As a result, the objects in the frame are approximately doubled without losing detail.

In the daytime, the iPhone X camera provides excellent image quality, with little to no noise. Sharpness and contrast are good, the contours of objects are clear, and the sky is rich blue, dips dynamic range no.

In addition to daytime shooting, the iPhone X camera provides a fairly high quality photo at night. Of course, without noise and blurring in any way, but for a smartphone the quality is very high.

An interesting feature of the iPhone X camera is portrait mode. It allows you to apply the effects of changing the lighting on the photo, simulating a particular environment. The main matrix keeps the person in focus, and with the help of the second camera the background changes.

In terms of video, the iPhone X also occupies a leading position among smartphones. Its camera can record videos in 4K resolution at 60 FPS. So far, no other smartphone can do this, everyone is limited to 30 FPS. iPhone X can do that, and is also capable of writing videos in the cinematic standard of 24 FPS.

In FullHD, the new iPhone shoots Slow-Mo at 120 and 240 FPS. Only the IMX400 sensor in the latest generation of flagship Sony Xperia smartphones, capable of writing at 960 FPS, can do more. But there, the recording time of Slow-Mo at such a speed is limited by the volume of a special RAM buffer, and you can shoot at such a frequency only for a period of several seconds. And the iPhone X can write at 240 FPS until the internal memory runs out.

All three phones have a 12-megapixel camera on the back, but there are some differences here too. The iPhone X camera has a bunch of new features, which we wrote about below.

The iPhone X and iPhone 8 Plus actually have two cameras on the back. It's an ƒ/1.8 aperture wide-angle lens and an ƒ/2.4 aperture telephoto lens that combine to create the stunning background blur portraits that these phones can produce. The iPhone X and Plus also have optical zoom and x10 digital zoom.

The iPhone 8's camera is also 12MP, but it's only one ƒ/1.8 aperture camera, so it can't capture fantastic portrait shots, and the digital zoom zooms in at 2x less - x5.

The latest flagship iPhone from , the iPhone X has many new features, but none as impressive as the front-facing TrueDepth camera, which was built for near-perfect facial recognition.

The TrueDepth front camera is whole system high-tech cameras and sensors that bring unique new features to iPhone X. On the iPhone X, the front camera received a major upgrade, a new FaceID feature for identity recognition to replace the fingerprint sensor, FaceID to support the required technology for identifying with Apple.

iPhone X features an infrared camera, stream light, proximity sensor, ambient light sensor, speaker, microphone, 7MP camera, and a dot projector that hits 30,000 dots on your face. The collected data is processed on Apple's A11 Bionic chip with the Neural Engine (which has been tested to be fast enough to bypass ).

The iPhone X camera features wide color capture, automatic image stabilization, exposure control, and portrait mode (including the new Portrait Lighting).

All these sensors, the camera and the improved processor, make Apple's new smartphone's front camera the best on the market.

iPhone X has a more advanced rear camera

Face ID uses Apple's new TrueDepth camera, which isn't on the iPhone 8/8 Plus. Face ID unlocks the phone - replaces Touch ID - and is used for things like Apple Pay. The notch is made up of sensors, cameras, and chips that the iPhone 8/8 Plus doesn't have: the "Point Projector." And "Spotlight Light" which uses invisible infrared light to identify your face when it's dark. And infrared camera, which reads a bitmap, captures an infrared image, then uses the data to validate a face ID match.

iPhone X and iPhone 8 – Cameras iPhone X: Dual 12MP cameras (f/1.8 and f/2.4) with OIS, 7MP front. iPhone 8: One 12MP (f/1.8, 28mm) with OIS, 7MP front.

The iPhone 8 isn't even close by comparison, as it only boasts a single 12-megapixel rear camera at f/1.8.

Elsewhere, however, the iPhone X and iPhone 8 are identical to the 7MP f/2.2 front and no OIS.

The new iPhones have two kinds of cameras. Both the 8 Plus and X have a dual rear camera setup that combines a wide-angle and telephoto lens. In addition to being able to zoom optically, these cameras can be used together to determine depth in a scene, allowing the iPhone to know how far away everything is. This allows you to create a scene depth map, which is the basis of the magic of new cameras.

So far, the depth maps produced by the iPhone 7 Plus have been used for something - blur the background in portraits and make the subject pop. This mimics the same effect on regular cameras, only there the background is blurred due to the properties of the lens and its longer distance from the camera's sensor.

iPhone X Camera - Portrait Lighting

Portrait Lighting makes a 3D model of the scene in your photo and re-lights it. The iPhone X makes a depth map generated by two cameras and then uses fantastic algorithms to identify faces and other image elements. It then analyzes and illuminates them into this 3D scene.

On a technical level, photography is nothing but light. And well-lit photos are what separates professionals from amateurs. Portrait lighting cannot replace the studio. The stunning promo photos already show what a difference the effects can be, enhancing our everyday photos beyond what's possible with any other camera – even the best DSLR with Photoshop behind it can't do what the iPhone X camera does.

iPhone 7 on the left and iPhone X on the right

Portrait lighting and the existing portrait mode are already amazing features and good enough to sell. a large number iPhone X and 8 Plus. But 3D maps can have an even crazier effect on your photography. For example, it's easier to pull people out of images, put them in new backgrounds, or combine multiple photos into perfect group shots.

iPhone X camera - All that, plus iOS 11!

Let's not forget the bonus software, which ships with iPhone X thanks to iOS 11.

In iOS 11, Apple is removing some of the shortcomings with portrait mode, such as improving image stabilization. Therefore, you can take low-light photos in portrait mode. Support for HEIF photos so you can capture ultra-high images, but with half the space and Live Photos editing tools so you can make them more beautiful.

You might think that the iPhone 7 Plus has the most advanced camera on a smartphone. But it's no candle to what the iPhone X is capable of. The advantages of a single TrueDepth camera make it the new best camera phone, and small but significant upgrades to the rear camera put the iPhone X in a category of its own.

Are there any other questions?

Ever since the introduction of the iPhone 4 to this day, the most popular camera, according to Flickr, is the iPhone. The new iPhone 6s are improved in many ways, both in general and in terms of the camera. The sizes of displays and their resolution are growing, but with the camera, Apple did not chase the "quantity" - these are the previous 8 MP, which have remained unchanged since 2011, since the iPhone 4s. However, Apple still carried out key camera upgrades for the new iPhones, and in this article we will discuss them with you.

The pixel size on both iPhone 6 cameras remains the same at 1.5 microns, and the lens has a five-element design with an ƒ/2.2 aperture and is no different from the iPhone 5s camera. Most of the new improvements are "under the hood" - they are software features and high performance: it is video shooting that can be considered the most significant improvement, although the arrival of optical stabilization, instant autofocus and 43-megapixel panorama mode can also be considered a huge gift for photographers.

1. Faster processor, more storage and new display

Obviously, "bigger" means "better" and it doesn't matter if we're talking about displays or legroom in an airplane seat. The larger screen and thickness of the iPhone 6 and iPhone 6 Plus not only make them more comfortable to hold while shooting, but also give you a wider viewing angle, better brightness and contrast thanks to the all-new Retina display, which is likely to make a big difference for photographers.

iPhone 6 Plus works in Full HD resolution of 1920x1080, while its "little brother" - in 1334x750 resolution.

Both iPhone 6s are powered by the same 64-bit A8 processors that have an integrated video processor and video encoder. They process all the photo and video functions of the camera, and also provide a longer operating time due to their energy efficiency.

Having at hand a good tool for creativity with high time battery life, allowing you to shoot cool videos, panoramas with high resolution - iPhone 6 photographers will need a lot of disk space. This time around, both the iPhone 6 and iPhone 6 Plus don't have 32GB versions - just 16 and 64, or the premium 128GB version (which will set you back $500 more).

2. Autofocus and Focus Pixels technology

New iPhones - new technology focus. As you know, Face Detection AF is more sensitive than Contrast AF. For this, two images are used, from which changing positions are determined to control the focusing mechanism, the purpose of which is to align these images relative to each other.

Contrast detection is significantly slower because it uses focusing directly from the sensor to determine the maximum point of contrast, which requires focusing back and forth.

Autofocus is reportedly twice as fast on the iPhone 6 as on the iPhone 5. Another welcome feature on the new iPhones is Focus Pixels, which implements continuous focus detection while shooting video. Manufacturers of DSLR cameras have recently begun to use something similar in their products.

3. Optical Image Stabilization in iPhone 6 Plus

The iPhone 6 Plus camera introduced optical image stabilization to reduce camera shake and shake during shooting. The slightest movement of your hand is tracked using a gyroscope, then processed by the A8 processor and M8 co-processor, after which the lens lenses shift in the opposite direction to compensate for the movement of the hand.

Optical stabilization has the potential to greatly improve photo quality in low light conditions and is especially effective when shooting video, reducing the well-known phenomenon of "seasickness".

Only the iPhone 6 Plus has optical stabilization, giving Apple another reason to differentiate the more expensive 5.5-inch version of the iPhone. Photographers using the iPhone 6 will have to make do with automatic image stabilization, a digital solution also found on the iPhone 5s. It consists in the fact that the camera takes four quick frames, determining the most contrasting parts of them, to create the final photo.

4. New frame rate for video

It is the video recording function in the iPhone 6 and iPhone 6 Plus that has been subjected to maximum improvements. And now, in addition to recording 1080p at 30 fps, we can shoot Full HD video at 60 fps. Increasing the frame rate results in crisper, smoother videos, although they will of course take up more disk space.

If you're editing captured videos into full-length movies, then importing 60 fps video into a project at a regular frame rate (30 fps) will allow you to slow down the video much smoother.

And, of course, you can always shoot slo-mo videos, which are a cut above the iPhone 6 and iPhone 6 Plus than the iPhone 5s. Instead of 720p videos at 120 fps, we have Full HD at 240 fps.

5. Time-lapse video, exposure and more

iOS 8 brings a lot of new features to both Camera and Photos for iPhone 6 and iPhone 6 Plus (as well as iPhone 5s and iPhone 5/5c) users.

The most prominent of these is the automatic creation of time-lapse video. You just need to press the record button and the iPhone camera will take frames at dynamic intervals. Such videos are not limited in length and can be both short and long - it all depends on your goals and desires. The only thing that is required of you is to keep the phone as still as possible.

6. Exposure control and editing

Another new camera feature that debuted in iOS 8 on the iPhone 6 and iPhone 6 Plus is manual exposure control. Yes, you can finally adjust the exposure before taking a photo or video, instead of editing the resulting files to make them lighter. You can set the exposure value with a simple swipe using the scale next to the autofocus square.

The Photos app hasn't been overlooked by Apple either, and we've got advanced editing options in it: automatic leveling of a littered horizon and fine manual adjustment of exposure, brightness, contrast, and shadows.

Apple also opened the PhotoKit editing framework API, allowing third-party developers to use the filters and editing features found in the Photos app.

7. High quality panoramas

The iPhone 6 and iPhone 6 Plus received an improved panorama mode compared to the iPhone 5/5s, the resolution of which can reach 43 MP (against 28 MP in previous generations).

And while shooting panoramas on the iPhone requires a steady hand from the photographer, automatically stitched images, even shot on the iPhone 5, are of excellent quality. Having a higher resolution means better printing, although such photos will, of course, take up more disk space.

8. Improved face detection

The cameras on both iPhone 6s offer improved face detection over the "standard" ones on the iPhone 5s. So if you were expecting slower or less accurate face detection, you will be disappointed.

Apple says the iPhone 6's iSight camera is not only better at detecting faces in the middle of a crowd, but it can also detect faces in burst mode. The definition of smiles and blinks, according to the company, has also been improved.

Whatever it was, but the iPhone 6 is a big step forward and the camera is no exception. Apple has done a lot of work and has given us smartphones with great cameras that we will have to shoot with over the next year. How do you rate the cameras of the new iPhones? Share your opinion in the comments.

Yesterday, November 17, the company Sony introduced a new improved sensor for smartphone cameras. In order for the development to be used in mobile devices, the manufacturer decided to make the sensor more compact. However, the novelty has received an improved quality of shooting and a high speed of processing tasks.

In contact with

It is worth noting that Apple uses in its iPhone and iPad Sony sensors, and it is likely that the novelty of the Japanese company will be implemented in future Cupertin devices.

New 21MP sensor Exmor RS IMX230 created on the basis of a chip with a multilayer layout. This development Sony has been using it for two years now, but the new sensor also introduces the ability to phase-track autofocus, as well as HDR shooting photos and videos.

According to statements Sony, Exmor RS IMX230 is the first CMOS sensor of its kind for smartphones that supports AF tracking with 192 AF points. This characteristic provides the matrix with almost instantaneous tracking of moving objects.

Autofocus function using 192 AF points

The sensor is also equipped with support for HDR-shooting photos and videos (up to 4K) – the camera will be able to create brighter and more contrasting pictures. Note that HDR allows you to capture individual images with different exposures, combining them into one more detailed photo.

Comparison of HDR images created by the IMX135 sensor (left) and IMX230

It's worth noting that Sony is well known for producing some of the best sensors available today. The high quality of the products is also evidenced by the fact that Apple has been using the sensors of the Japanese company in its devices for quite a long time. It is expected that deliveries of new matrices for Cupertinians will begin in April 2015. Most likely, the sensors will be included in the iPhone and iPad, but even the approximate time frame for this process is unknown.

In most cases Apple does not equip its smartphones and tablets with multi-pixel sensors, so the new Sony may not get to the "apple" gadgets. However, the Japanese company intends to launch 16-megapixel IMX230 sensors in 2015, and they are ideal for iOS devices. It is likely that the IMX230 sensors will appear in the 2015 iPhone. However, there is a possibility that matrices will not be used before 2016.

According to Tom's Hardware Portal, iPhone 7 may get either the upcoming 16MP IMX240 sensor from Sony or the 13MP IMX135 sensor that arrived in January 2013.

According to experts and equipped with an 8-megapixel Sony ISX014 sensor, introduced in October 2012.
