The Pixel Visual Core is a custom image processor on the Pixel 2 devices that does hardware acceleration of the various image processing algorithms, primarily the HDR+ effect, which greatly increases the dynamic range of the image while reducing noise. It also includes RAISR, which uses machine learning to upscale digitally zoomed images and make them sharper.

Developers can now modify their apps to access this hardware if their app supports taking picture so their app can also take the same high quality images as the main camera app.
Also, in the coming days, Google will also be rolling out the new AR stickers with a winter sports theme. These will only be available in the main camera app.
