Light and Sony team up to make the next-generation of multi-camera smartphones

22 Feb

Light, the computational imaging company behind the L16 camera, has announced it’s partnering with Sony Semiconductor Solutions ‘to jointly work on development and marketing of multi-image sensor solutions.’

According to a press release shared today, the two companies have signed an agreement that ‘allows Light to use and recommend to its customers and partners, Sony’s image sensors built in Light’s computational imaging solutions and reference designs.’

Simply put, the agreement means Light will combine its experience and intellectual property in the world of multi-camera designs and computational photography with Sony’s imaging sensors to build future devices. Specifically, the press release mentions the partnership will help ‘to create new multi-camera applications and solutions beginning with the introduction of smartphones containing four or more cameras.’

Light previously announced its intentions of bringing its multi-camera technology to smartphones, going so far as to show off various concepts and prototypes it’s developed that include between five and nine camera modules.

Bradley Lauterbach, Senior Vice President of Marketing and Product Design at Light, also said back in December 2017, ‘one manufacturer is already at work on a Light-enabled phone, and more are in the works.’ It’s unknown if Lauterbach was referencing Sony, but whoever the manufacturer was, it appears clear now Sony will be the company behind the sensors.

Samsung and Huawei introduce the ‘hole-punch’ front camera in their latest smartphones

12 Dec

Smartphone manufacturers are facing a dilemma these days. Consumers want a display that covers as much of the front of the device and has bezels that are as thin as possible. On the other hand some components, for example the front camera, proximity and light sensors or the earpiece have to be placed onto the front of the device as well to work efficiently, taking away some of the available real estate from the display.

This has resulted in the much-dreaded display-“notch” as it was first popularized by the iPhone X and since then has appeared on most other high-end phones as well.

Samsung and Huawei are now going down a different route, however, with their new A8s and Honor View20 models, respectively. Both new smartphones feature a so-called ‘hole-punch’ front camera which is designed to be less obtrusive than a ‘notch.’

In this design the camera is hidden behind the display which comes with a small circular hole for the lens to peek through. It’s worth noting however, that unlike many current high-end models neither the A8s nor the View20 come with any face recognition features that would require additional sensors at the front. Both new devices are placed in the mid-range bracket of the market which makes them more suitable for the new design.

The View20’s main camera also comes with a promising specification. The camera features the same 1/2″ Sony sensor with 48MP resolution that we are also expecting to see in an upcoming Xiaomi device. The sensor’s high pixel count is used for high-quality digital zooming and computational frame-stacking methods, though, so don’t expect any medium-format resolution out of your smartphone any time soon.

Advantages DSLRs Have Over Smartphones, and Why They’ll Always Have Them

22 Nov

I love watching the annual press events of Apple, Google, Samsung and others where they show off their latest high-tech gadgets, including mobile phones. With each new iPhone, Pixel, and Galaxy they seem to repeat a common refrain: “And the camera is the best one ever in a smartphone”.

Are DSLRs fading away with modern advances in smartphone camera technology? Or are they primed and ready for an entirely new life?

Mobile phone cameras are mind-blowing marvels of modern technology. With some of the tech showcased in the recent Pixel 3 announcement, you might be wondering if traditional DSLRs and mirrorless cameras are even relevant anymore.

The answer is more complicated than you might think.

Before you get too deep into this post, I want to make one thing abundantly clear. No-one can tell you which camera is best for you. If you have a 3-megapixel point-and-shoot that does what you want, then, by all means, keep using it and don’t let anyone stop you. Also, if your smartphone takes selfies and Instagram-worthy photos of your morning coffee, then keep snapping away.

In this article, I’ll be looking at some advantages traditional cameras have over smartphones. However, I won’t be telling you which one to buy, and I certainly won’t be telling you to stop using the camera you already have. Too often, the point is missed entirely when people get caught up in silly arguments on internet forums and message boards about whether such-and-such camera is better.

It’s important to know the advantages and disadvantages of different cameras, so you have enough information to choose one that best suits you and your needs. However, please don’t think I’m trying to tell you what you should or shouldn’t buy.

In almost every way I can think of, modern smartphones can take incredible images compared to those from just a few years ago. These days they have real-time HDR, depth mapping, background separation, multiple lenses, machine learning, portrait mode, selective bokeh adjustment, and even computer-assisted sub-pixel digital zooming. It’s enough to make even the most staunch DSLR owner feel a tad envious.

Still, don’t toss out your Canon or Pentax just yet. DSLRs and other traditional cameras have a treasure trove of advantages no current smartphone can match, and some features they may never be able to achieve.

Lens Selection

What’s the essential advantage of DSLRs over smartphones? I couldn’t tell you, but lens selection would undoubtedly be near the top of the list. Despite all the advances in smartphone photography in recent years, some laws of physics and photons are only overcome when switching lenses like a traditional camera. Most mobile phones have lenses roughly equivalent to a 28mm lens on a full-frame DSLR, although some dual-camera models roughly mimic a 50mm field of view to try and recreate professional-style portraits. Even though you can get adapters (such as the Olloclip) that let you do some creative experimentation, they rarely hold up to dedicated lenses mounted on interchangeable-lens cameras.

By comparison, DLSRs can use hundreds of different lenses, each designed for specific photography needs and situations. No matter what you need from a DSLR, there’s a lens that does it – from wide-angle primes and telephoto zooms to basic kit lenses, tilt-shift, and specialized macro lenses.

A photo like this, which requires a telephoto lens with a wide aperture, isn’t currently possible on any smartphone (and may never be).

The AI-powered tricks and computational somersaults modern cell phones are capable of can work wonders for different photographic situations. But when it comes to choosing the perfect lens for the job, smartphones simply can’t compete. If you want to shoot close-up images, far-away wildlife, fast-moving sports or pleasing group portraits, your mobile phone will probably come up short. Sure, you can’t install apps on most DSLRs. But you can change out lenses which, when it comes to photography, is infinitely more useful.

The portrait mode on mobile phones is amazing. But it doesn’t come close to what you can achieve with a portrait lens on a DSLR or mirrorless camera.

Customizable Settings

While phones can produce amazing photographs in lots of different conditions, you’re fairly limited in terms of settings. You usually can’t change the aperture or focal length (and no, digital cropping is not the same as changing focal lengths). All you can really control are the ISO and shutter speed, and the native camera apps rarely even let you do that much.

When you press the button to take a picture on your phone, you’re letting the computer do most of the thinking it terms of white balance, shutter speed, ISO, and even which part of the image should be properly exposed.

One of the biggest selling points of DSLRs and other dedicated cameras is that (while they have auto modes that do much of the heavy lifting) they have manual modes that let you choose everything – aperture, shutter speed, ISO, and even the focal length if you’re using a zoom lens. Admittedly, not everyone wants that much control, and you can choose to shoot in auto or semi-auto if you want. But having such fine-grain control is a huge advantage over smartphones.

I could choose a slow shutter speed to get this shot on my Fuji X100F, whereas most mobile phones would have used a much faster shutter speed resulting in a vastly different image.

Smartphones and the software that powers them are so advanced and sophisticated that people are perfectly happy letting them make the decisions and do most of the heavy lifting. But if you want more control you won’t get it on a mobile phone. Even the dedicated camera apps run up against physical limitations such as focal lengths that can’t be changed.

There are times when the photo you want to take isn’t the photo your camera wants to take. In those situations, a dedicated camera will let you change aperture, shutter speed, and ISO to get the exact photo you want.

I shot this image at 200mm, f/2.8, ISO 100, and 1/4000 second, which is impossible for any mobile phone.

Low-Light Shooting

DSLRs will always have the advantage over mobile phones in low light due to the way camera sensors collect light. Larger sensors mean larger photosensitive sites, which means they can capture more information about incoming light when there isn’t a lot of it.

At Google’s recent Pixel 3 announcement they demonstrated a feature that vastly improves its low-light shooting. But it only works with still subjects. It also runs into the same limitations all mobile phones have such as fixed focal length and limited options for changing settings.

I took this deep under the earth in Mammoth Cave National Park, 23mm, f/2.0, 1/20 second, ISO 6400. While some phones could have taken a shot similar to this they would have needed much longer shutter speeds, which would make the people a blurry mess.

Try it for yourself to see what I mean. Even with the best night-mode options on the newest mobile phone, you’ll still struggle to get clear shots of moving subjects. It’s great if you only require pictures of static compositions such as buildings or parked cars. But if you want to capture shots of kids, animals or anything that moves around, your mobile phone will probably leave you wanting more.

As the technology advances, low-light photography on mobile phones will improve. But there will always be physical limitations inherent in the platform that DSLRs and mirrorless cameras simply don’t have to deal with. Much of it stems from their larger image sensors, which collect much more light data per pixel. But the fact cameras let you specify the ISO value you need to get the image you want is also a big advantage.

Not Quite There… Yet

I’m a big believer in the promise of computational photography in mobile phones. If the best camera is the one you have with you, then for hundreds of millions of people around the world their mobile phone is the ideal choice. But even with all the rapid advances in technology, there are still plenty of reasons to own a traditional camera.

If you have one that’s been relegated to a dark closet or dusty shelf and replaced by a high-tech mobile phone, get it out and see what it can do. The results may surprise you and have you wanting to use it more and explore the possibilities it offers.

What about you? What are the advantages of using traditional cameras that keep you coming back to them time after time? I’d also like to hear your thoughts about mobile phones and the technology they offer photographers.

One thing is clear. No matter where you stand on this issue, we certainly live in exciting times for photography.

Qualcomm’s 700-series chipset will bring triple-cameras to mid-range smartphones

13 May

With the Huawei P20 Pro there is still only one triple-camera smartphone currently available on the market. We have already heard that Apple might be launching a third generation iPhone X with triple-camera in 2019, but now it seems the technology could trickle down to mid-range devices even before that.

Specifications for Qualcomm’s upcoming 700 series mobile chipset have leaked on Suggestphone.com, and the documents indicate the new chipset will support triple-cameras as well as AI processing accelerators. The latter should come in handy for all sorts of AI-powered imaging tasks, such as scene and object identification. The former… well that one’s obvious.

The Snapdragon 700 series should slot in nicely between the current SD600 series (which powers mid-range smartphones up to around the $ 500 price point) and the Snapdragon 800 line (which is reserved for high-end models).

Image: Suggestphone.com

The Snapdragon 710 was allegedly designed using a Samsung 10nm LPE process for low power consumption and higher performance than previous 14nm chipsets. The Snapdragon 730, meanwhile, builds on the newer Samsung 8nm LPP process, resulting in a 10% smaller surface area and 10% lower power consumption than the 10LPP process. It’ll also provide more oomph than the SD710.

The first smartphones with the SD710 chipset are expected to hit the shelves in early 2019; we’ll have to wait a little longer until later in 2019 for the SD730. Hopefully we’ll see a few SD8xx-powered triple-cameras before then, but it’s reassuring to know more affordable triple-camera will be available in the foreseeable future.

Apple patent describes dual-live-view for dual-camera smartphones

12 May

A new patent application from Apple describes an interesting, alternative approach to displaying live view images from dual-camera-equipped smartphones when you’re trying to frame a shot.

On Apple’s current dual-camera phones—the iPhones 7 Plus, 8 Plus and X—the image data from both sensors is merged computationally to provide a seamless zoom experience. The end user can’t tell if they’re looking at a live-view image captured by the main camera, by the tele-camera, or a combination of both. The concept is the same for tele-camera phones from most other manufacturers.

The system described in the patent works differently. It shows the images from both cameras simultaneously, side-by-side. This would allow users to compare the field-of-view of both lenses, and pick the one they prefer.

According to the patent, the dual-view mode would allow for independent zooming and panning of each camera view. In theory, the photographer could take two photos simultaneously, each with different zoom factor and framing. The system would work in the same way in video mode, letting the shooter focus on a particular detail of a scene while simultaneously recording the wider context.

As usual, there is no way of knowing if this idea will ever make it into a production device, especially since the current way of dealing with dual-camera live images is arguably easier and clearer to most users. But as a user-selectable alternative mode, the system described in the patent application actually makes a lot of sense.

Let us know what you think of this idea in the comments.

Sony’s updated 3D Creator app can use your smartphone’s front camera to scan your face

21 Apr

Sony’s 3D Creator app with its 3D-face-scanning function was first introduced with the Xperia XZ1 and XZ1 Compact last year. Now the Japanese manufacturer is rolling out the update to version 2 of the app.

The most important upgrade of the new version is the ability to create 3D models of your face with your smartphone’s front camera. This means, unlike with the previous version, you don’t need the help of another person to create a 3D-model of your face and head. Of course, the option to use the main camera and get someone else to do the job is still available.

The updated app also lets you share the results straight to Facebook or order a 3D-printed copy of your model. And version 2.0 also comes with “post-scan cloud processing,” which allows you to render 3D models with 4K resolution textures for better detail and realism.

3D Creator 2.0 is compatible with the Xperia XZ1, XZ1 Compact, and XZ Premium. If you’re lucky enough to own one of these devices, you can download the newest version of the app from the Play Store now. If you are an iPhone X user, check out the Bellus 3D app for similar face scanning capabilities.

Instagram ‘Focus’ mode brings fake bokeh to single-camera smartphones

11 Apr

Instagram has released version 39 of its iOS and Android mobile apps, and the update brings with it a background-blurring portrait mode similar to the “Portrait”, “Depth” and “Bokeh” modes we have seen on most recent high-end smartphones… with one major twist.

While the baked-in bokeh modes on most smartphones use the slightly offset lenses of a dual-camera setup, or other partly hardware-based methods to create the effect, Instagram’s version appears to solely rely on face detection. That means you shouldn’t expect perfect subject/background isolation and super-smooth blur transitions, but it also means single-camera phones can take advantage of the feature.

Focus mode is available in the Stories camera UI, right next to “Superzoom”. It works with both front and rear cameras, automatically blurring the background when one or more faces are detected. Focus mode works on the Apple iPhones SE as well as the 6S, 7 and 8 generations and the iPhone X. It is also available on “select Android devices”, which appears to include most current high-end Androids.

In short: Focus mode looks like a nice addition to the Instagram feature set, but if your smartphone offers a native portrait mode you’re probably better off using that and inserting the image into Instagram via the gallery or camera roll. To find out more about Focus, head over to the Instagram Press blog or update the app and give the feature a try for yourself.

Sony Xperia XZ2 brings 4K HDR video to smartphones

26 Feb

Sony Mobile’s contribution to the Mobile World Congress 2018 comes in the shape of the Xperia XZ2 and XZ2 Compact smartphones. With a 1/2.3″ 19MP image sensor and F2.0 aperture the basic camera specs remain unchanged from the predecessors, but the cameras in the new models offer a couple of improvements that will be especially welcome by mobile videographers.

The Xperia XZ2 and XZ2 Compact are the first smartphones capable of recording 4K HDR video footage, using the Hybrid-Log-Gamma (HLG) standard. This means 4K HDR clips shot on the XZ2 will be playable on most HDR-capable TVs and can be processed by Youtube.

The phones are capable of processing the massive amounts of data that is recorded for HDR video thanks to a built-in DRAM buffer in the imaging chip. The same technology also helps drive Sony’s motion-eye super-slow-motion mode that was first introduced last year. The 2017 Sony flagships could record 960 frames per second at HD resolution for 0.2 seconds, resulting in 6 seconds of playback time – the same as on the brand new Samsung Galaxy S9.

The new models come with an 18:9 aspect ratio display.

On the new XZ2 Sony has taken things one step further and offers the same frame rates at 1080p Full-HD resolution. On the downside, recording time is cut in half, to 0.1 seconds, resulting in 3 seconds of playback time. Super-slow-motion clips can be embedded in standard video, though, so there is plenty of opportunity to get creative with the super-fast frame rates.

Both new devices are powered by Qualcomm’s latest top-end chipset, the Snapdragon 845 and come with Full-HD displays with 18:9 aspect ratio – 5.7″ in size on the XZ2 and 5″ on the Compact model. The latter remains pretty much the only option in the market that combines a compact form factor with high-end performance.

Apart from display size the XZ2 and XZ2 Compact differ in several ways: the smaller model does not offer Qi wireless charging nor the new Dynamic Vibration function that translates sound, for example when watching videos or playing a game, into vibrations for a more immersive media consumption experience. It also comes with a smaller battery (2870 mAh vs 3180 mAh) than its larger cousin.

More information on the new Sony Xperia XZ2 and XZ2 Compact is available on the Sony website.

Microsoft Photos Companion app offers easy photo transfer from smartphones to PC

17 Feb

Microsoft has launched a new app to facilitate easy photo transfer from mobile devices to a Windows 10 PC, without using the cloud. Photos Companion is available for iOS and Android and deposits your mobile images in the Windows Photos app on the desktop or laptop PC using just a WiFi network.

To get started, you have to scan a QR code in the Windows Photos desktop app to pair smartphone and computer. Both devices have to be connected to the same WiFi network, which in turn allows you to send individual images or entire batches across very quickly. It is, in essence, the exact same system as Apple’s AirDrop, but limited to photos and videos.

Pairing isn’t permanent, and will have to be re-established for each sharing operation. Still, that’s easily done and the app looks like an interesting solution for collecting media files from multiple mobile devices on a single PC for working on collaborative projects.

Once on the PC, images and videos can be shared and edited in the Windows Photo app as usual. If Photos Companion sounds like an app that could potentially improve your workflow, you can find more information and app store links on the Microsoft website.
