Google may be having some display quality issues with the Pixel 2 XL but the cameras on their two new flagship smartphones are top notch. The company opted for EIS last year with the original Pixel and Pixel XL, while this year they are using a combination of EIS as well as OIS hardware. To leverage these two technologies, Google is using what they're calling Fused Video Stabilization and today, they explain what it is and how they accomplished all of it.
When Google was researching on what to improve from the original Pixel phones, they looked at what the main camera issues that many smartphones owners come across. This included camera shake since most of us are holding the phone in our hand(s) and it is often difficult to be completely still. Motion blur can also be an issue from if the camera or the subject moves during exposure. Another common issue is rolling shutter distortion which happens because of the way CMOS image sensors work. The last one Google mentions is known as focus breathing which can happen when the angle of view changes significantly due to objects "jumping" in and out of the foreground.
OIS is popular as a solution to these problems as it helps to eliminate some of these issues, but it can be limited in its implementation. The same can be said about EIS as it all depends on the algorithm used but again, for it to work, it inherits some limitations like needing to reduce the field of view or resolution.
So Google combined both technologies and both are enabled during video recordings, allowing them to address all of the issues mentioned above. The solution they came up with involves three processing stages where it first analyzes the motion by using the phone's high-speed gyroscope to estimate the rotational component of the hand motion (roll, pitch, and yaw). Next up is the motion filtering stage where they combine machine learning and signal processing to predict the intention in moving the camera. Lastly, we get to the frame synthesis stage where the software models and removes the rolling shutter and focus breathing distortion.
Thanks to these techniques, the videos produced on the Pixel 2 and Pixel 2 XL have less motion blur and look more natural.

Sony's Xperia XZ1 gets another price cut in the US and this flagship device is currently available for $589 on Amazon which is $110 lessor than its previous price. Currently, the Blue color variant is priced at $589 while the other options are available for $599.99. There is no information on how long the price cut will be implemented or till when the offer is valid so the users need to act soon to get their hands on the Xperia XZ1 for a discounted price.
Coming to the device, the Xperia XZ1 was launched a few weeks back and came with a 5.2-inch IPS LCD display with 1080 x 1920 pixels resolutions giving a pixel density of 424ppi with the latest Corning Gorilla Glass 5 protection on top. Moreover, under the hood, there is the Qualcomm Snapdragon 835 SoC Octa-core processor coupled with 4GB of RAM and Adreno 540 GPU. Sony is known for making good camera smartphones and this device comes with a 19MP main sensor with EIS, F/2.0 aperture size, laser autofocus and LED flash.
It also comes with features like touch focus, face/smile detection, panorama, HDR and few other sensors. It is also capable of capturing 2160p videos at 30fps and it will be accompanied with a 13MP camera on the front for video calls and selfies which also comes with EIS and 1/3" sensor. There is a fingerprint sensor on the side to enhance the security levels and has sensors like proximity, parameter, compass and few other.
There is a non-removable Li-Ion 2700 mAh battery on the back and comes with quick charge 3.0 for fast charging. The handset is available in Black, Warm Silver, Venus Pink, and Moonlit Blue color variants. The onboard storage is limited to 64GB which can be extended up to 256GB via microSD card slot. Are you planning to get this device on discounted price? Comment in the section below and stay tuned for more news and updates.
