Got some old, blurry photos? Google's got a fix for that.
Photo Unblur is an expansion of 'Face Unblur', which arrived last year on the Pixel 6 and Pixel 6 Pro. The latter has quickly become one of the most popular computational photography features since Google unveiled 'Night Sight' on the Pixel 4 back in 2019. But it's also quite different from Photo Unblur, which means the two will act as complementary modes for varying situations.
Photo editors have long had sliders to help you adjust noise and sharpening, but Google's new tech is much smarter than those. For starters, it analyzes your whole image to work out the levels of noise and blur down to a pixel level, regardless of which camera the photos were taken on. These are counter-intuitive because they involve pushing your photo in the seemingly 'wrong' direction, before bringing it back to an improvement on the original. To reduce noise, Google combines noisy pixels , then merges them together while regenerating finer detail. The sharpening works in a similar fashion, with Google's algorithms re-blurring the image several times in an efficient, phone-friendly process.
The image below, for example, has been impressively cleaned up from its almost unusable origins, which appear to have been caused by light movement and an excessively slow shutter speed.
