From the actual review the article links to, I've got to say, this is pretty cool:
Super Res Zoom is Google’s software that aims to make up for the missing telephoto lens. The machine learning–powered feature makes photos taken with digital zoom look better. Typically, photos taken with optical zoom are higher resolution, while digitally zoomed photos look grainy and blurry.
Here’s how it works: Whenever you take a photo, your hand is never perfectly still. It moves ever so slightly. Super Res Zoom uses those hand vibrations to capture the image from slightly different angles to get more information from that scene. Those angles are used to make digitally zoomed-in photos appear more detailed and higher resolution.

- tempestn 8y agoActually it says older Pixels will get it too.
- dplgk 8y agoOh, that would be surprising and great!

- londons_explore 8y agoThe novel bit here is being able to do it in a couple of seconds on a phone. They have custom silicon for it (the same bit that does the on-device machine learning), it's that compute heavy. They need to do it in a couple of seconds because the RAW video (used as input to make a single photo) is gigabytes per second of data. If you do it slowly, you run out of RAM if the user tried to take another photo.

- diggernet 8y agoSounds great for a static scene, but it's bound to cause problems when zooming in on moving subjects.
- londons_explore 8y agoThey use optical flow to handle moving images just fine
