For its latest smartphone generation, Google has dropped the Nexus moniker of previous models and used Pixel branding borrowed from the company’s top-end Chromebooks and tablets. The Pixel XL is the larger of two models and comes with a 5.5″ QHD-screen that uses AMOLED technology. 

In terms of technical camera specifications, not much has changed compared to last year’s Nexus devices. A 1/2.3″ 12MP sensor is paired with an F2.0 aperture but offers no optical image stabilization. However, Google has flexed its muscles on the software side of things and added a new gyroscope-based video stabilization system that reads gyro data 200 times per second for smoother panning and shake-free handheld video recording.

Additionally, thanks to more powerful processing and zero shutter lag the excellent HDR+ mode is now on by default, using an image stacking approach to reduce noise, capture better detail and increase dynamic range. While the Pixel XL’s camera hardware looks promising, it is these innovative algorithms that make the Google device one of the most interesting smartphones for photography released this year.

Google Pixel users reporting camera app issue

02 Dec

Google’s Pixel smartphones come with a range of innovative imaging technology and currently occupy the number one spot in the DxOMark smartphone ranking. However, shortly after the device launch some users reported a strong tendency of the Pixel camera to produce lens flare, and now it appears some devices are having trouble with the camera app, as well. 

In the Google Product Forum a number of users are reporting that their camera app is frequently crashing, sometimes showing pink and purple vertical lines. It appears the issue is mainly impacting international devices when the phone is in an area with poor signal reception. The error does not occur when flight mode is activated. 

Source: Google Product Forum

Google support staff has been instructing users who are experiencing the issue to clear the cache and data, and factory reset the device. However, none of these measures has solved the problem. It appears performing a soft reset by holding the volume down and power keys is currently the only way to get your device up and running again when the issue occurs.

We are currently testing the Google Pixel XL for our full review and, luckily, have so far not experienced the problem. That said, we hope Google can come up with a quick solution, possibly a software update, to help the affected users.

Google acknowledges lens flare issue on Pixel camera, promises software fix

27 Oct

Since the Google Pixel and Pixel XL smartphones have become available for purchase, there have been several reports about the camera of the devices, despite stellar scores in the DxOMark ranking, being very prone to lens flare with the sun at a certain angle to the camera lens. Now a group of affected Reddit users has described the problem in the Google Product Forum and got a quick reply from a Google employee:

‘First, for some background — flare is a property of ALL camera lenses. It comes in a ton of different shapes and sizes and can even be used for creative effect — good and bad :-). The shape, color, amount, etc. of flare is related to dozens of different parameters of the lens structure and inclement light. However, we have seen reports about this “halo/arc flare”. This is the specific kind of flare that appears as a bright/low-contrast arc in the corners of the frame.
 
You can expect a software update in the next few weeks that will improve the effects of this issue. We’re working on some algorithms that recognize the halo/arc flare, characterize it mathematically, and then subtract it from the image. 🙂 You will need to use HDR+ to see the benefits of this software.’
 
So it appears Google is planning to solve a hardware problem with a software solution and bake an algorithm, that mathematically removes the flare from the image, into the Pixel camera’s HDR mode. This means the measure will only be effective when shooting in this mode and it remains to be seen if there is any impact on noise and/or image detail in the affected areas of the image. We will certainly have a closer look at the Pixel’s flare behavior in our own test of the device.

Google Pixel XL added to mobile studio test scene comparison

26 Oct

Google’s Pixel and Pixel XL have garnered plenty of interest for their imaging capabilities since they were launched in the beginning of October. They each offer a 12.3MP camera with an F2.0 lens and a 1/2.3″ sensor – the same size used in yesteryear’s compact cameras – sporting 1.55µm sized pixels. The Pixel phones also utilize gyroscope-based stabilization for some seriously smooth video recording.

We got our hands on a Pixel XL review unit, and while we wait for the clouds to part outside for some real-world samples, we put it in front of our studio test scene. Take a look below at its JPEG and Raw performance in daylight and low light. It’s quite impressive: the lens is relatively sharp across the frame, and our low light Raw shots show that despite receiving 1.33 EV less light than the iPhone 7, the Pixel shows only slightly more noise, meaning it comfortably outperforms the iPhone camera in low light.*

*Multi-frame noise reduction – used in low light by both the Pixel and iPhone 7 – may skew results in either direction for either camera, providing better performance for static subjects, or potentially blurry images for moving ones.

Google shows off Pixel imaging capabilities in demo video

19 Oct

Nat and Lo is a YouTube Channel that started out as a ‘20% project’ within Google and has an objective to ‘demystify the technology in our everyday lives.’ Now the makers of the channel have published a video that was almost entirely shot with Google’s recently announced Pixel high-end smartphone.

The Pixel comes with a A 6-element lens with F2.0 aperture, a 1/2.3″ 12.3MP sensor with 1.55µm sized pixels, on-sensor phase detection with laser-assist and a gyroscope-based electronic video-stabilization system. The demo video shows off all of those capabilities and features, mixing 4K output of the front camera with 1080p Full HD footage from the front camera and some slow-motion sequences. A comparison shot shows the efficiency of the new video stabilization system and viewers can enjoy some nice still images and panorama shots of New York City. 

The video doesn’t really show anything that we would not have seen before on various other mobile devices but gives a good overview of the Pixel’s imaging capabilities. To judge for yourself watch the video at the top of this page and don’t forget to flick on the 4K switch on YouTube.

Google’s Pixel phones: What you need to know

06 Oct

Everything you need to know about Google’s new Pixel phones

Google’s 2016 smartphones have dropped the Nexus moniker and, in line with the company’s high-end Chromebooks and tablets, have instead adopted the Pixel brand. Despite being made by HTC the Pixel and Pixel XL are marketed as Google devices and only differ in terms of screen size and resolution as well as battery capacity. A 5″ 1080p AMOLED display and a 2,770mAh battery can be found on the standard Pixel, while the XL comes with a 5.5″ QHD-screen and a 3,450mAh battery. 

Both devices are powered by Qualcomm’s top-end chipset Snapdragon 821 and 4GB of RAM. The metal body with glass inlays on the back also houses a fingerprint reader, USB Type-C port for quick charging and a 3.5mm headphone-jack. In the US the devices will be available in black, silver and blue, with pricing starting at a fairly steep $ 649 for the standard Pixel with 32GB of built-in storage. 

The Pixel and Pixel XL have generated a lot of buzz for their imaging capabilities in a short amount of time – click through to see what else you should know about the new Google Pixel phones.

New camera hardware

Google says the camera stack used by the Pixel has been redesigned, even though on paper the camera specifications are similar to last year’s Nexus models. A 6-element lens with F2.0 aperture is placed in front of a 1/2.3″ 12.3MP sensor with 1.55µm sized pixels. On-sensor phase detection is on board as well and a laser-beam helps measuring the subject distance in low light for even better AF-accuracy. A dual-tone LED flash should make for pleasant skin tones when shooting with the built-in lamp in very low light.  

On the video side of things the Pixel phones can record up to 4K video at 30fps. In slow motion mode you can shoot Full-HD footage at 120fps or 720p video at 240fps. Perhaps the most notable new feature is a gyroscope-based electronic video-stabilization system that looked very promising in Google’s demonstration video during the launch presentation. It reads the gyroscope 200 times per second in order to correct for any camera movement and also helps reduce the “jello-effect” that is often noticeable on CMOS-sensors when panning the camera.

The front camera specification would not have looked out of place on a main camera only a few years ago. A 1/3.2″ 8MP sensor with a 1.4 µm pixel size and F2.4 aperture should allow for decent selfies in most conditions and the front camera is also capable of recording 1080p video. 

Imaging software

While the Pixel’s camera hardware is pretty much in line with other high-end smartphones, it’s the imaging software that really sets the Google devices apart. Thanks to more powerful image processing and a zero shutter lag the camera can now use Google’s excellent HDR+ mode, which has been available in the Google Camera app for a while, by default, without any noticeable processing delays for the photographer.

Instead of taking one longer exposure, HDR+ captures multiple images, aligns them algorithmically and merges them. This results in improved dynamic range, lower noise levels and better detail at all light levels but is especially helpful in low light conditions. Additionally, Smartburst captures several frames just before and after you press the shutter button and then, thanks to Google’s image recognition technology, selects the sharpest and clearest photos with the most pleasant facial expressions to display. Google also says the Pixel is quicker than any other smartphone in getting ready to capture a picture.  

Best ever DxOMark Mobile score

It appears the Pixel’s high-end camera hardware and Google’s clever imaging algorithms are working together very well. DxO has already tested the Pixel camera before its launch and with a score of 89 the Google device is the best smartphone ever tested. It takes the top position in the DxOMark rankings ahead of such illustrious competition as the new iPhone 7, the Samsung Galaxy S7 and the HTC 10.

The DxO testers were impressed by the great detail and low noise levels across all light situations. They also found exposure to be spot on and the autofocus to be very accurate, both in still in video mode. You can read the full report on DxOMark.com.

Unlimited cloud storage for photos and video

Like previously the Google Nexus devices, the Pixel phones do not come with a microSD memory expansion slot. This is something many mobile photographers won’t be too happy about but the Pixel is meant to be a cloud device and Google is emphasizing that by offering free unlimited cloud storage for full-resolution images and even 4K video in Google Photos.

A Smart Storage option will upload images and videos storage to your personal cloud and delete them off your phone automatically when your local storage starts to get full, similar to the Nextbit Robin. So nothing is stopping you now from recording that feature film in 4K resolution – just make sure you’re close to a reasonably fast internet connection. 

Android Nougat 7.1

The Google Pixel devices are not the first smartphones to come with Android 7 Nougat – that honor went to the LG V20 – but for its own devices Google has launched version 7.1 which comes with a few modifications, some of which are specific to the Pixels. 

One of the most notable differences is the new launcher that comes with an opaque shelf and round icons and folders. Other cosmetic differences include blue accents and custom navigation bar icons. In addition to unlimited photo storage Pixel users will also enjoy Google’s 24-hour tech support service. You can call or chat with a trained representative right from the device settings.

New features that are not exclusive to the Pixel phones are fingerprint gestures, which for example let you swipe down on the sensor to open the notification tray and the Night Light feature, a blue light filter that is activated at night. Seamless Updates downloads and installs updates in the background while you keep working on the device. They are then activated after a restart, similar to what you’re used to from a Windows PC.

Of course version 7.1 also offers the new features we’ve already seen on the original Nougat, such as ‘Project Doze’ which makes the phone use less battery while it’s not in your hands with the screen on and the ability to reply directly to notifications from the notification tray, without opening the corresponding app first. 

Google Assistant

Google Assistant is Google’s Version of Siri or Cortana and a much more intelligent version of Google Now. Assistant uses machine learning to become more useful the more you use it and in the future will come with different “personalities” for different types of tasks.

The version in the Pixel phones is already able to set and send calendar reminders, search for and book restaurants, find gas stations while you are on the road or play music while you are at home among many other things. It remembers every interaction and is therefore capable of having conversations rather than just receiving commands. Google Assistant uses data from your personal Google account in combination with voice and image recognition technologies, the built-in sensors in the phone and machine learning methods to offer its services.  

Daydream View VR-headset

The Pixel and Pixel XL are the first devices ready for Google’s Daydream VR technology that was first demonstrated at the I/O conference in May. Together with the smartphones Google has now also unveiled the Daydream View headset, which at $ 79 is meant to bring VR to the masses. The headset is made with a soft and breathable fabric that allows for extra comfort and makes it easy to use the headset over glasses. As a side-effect it is approximately 30% lighter than similar devices, for example Samsung’s Gear VR. 

Phone and headset come with an auto-alignment system, so once the Pixel is dropped in the Daydream VR you don’t need to worry about any cables or other connections. Daydream VR comes with the Daydream controller remote control that lets you interact with the virtual world you are moving in. It has a number of sensors to interpret your gestures and movements and offers high levels of precision. When not in use it slides into the headphones, reducing the risk of losing it.
