DeblurIt is a professional way to sharpen blurry photos. It provides unrivaled clarity and successfully removes motion blur, out-of-focus blur, gaussian blur from your images. Fix photo blur and sharpen non-blurred images with DeblurIt!
It uses progressive algorithms based on deconvolution technology. While commonly used "unsharp mask" filter just detects the edges and adds them to the original image, deconvolution uses information within the image to approximately restore the original state and fix photo blur. Deconvolution perfectly restores photos with large defects, recovering lost details. DeblurIt is the only app that supports deconvolution on Android (28.02.2013)
You can also use unsharp mask filter that removes blur in more standard way. It is the best fit for small defects.
Auto mode uses unsharp mask to quickly remove small blur from the photo.
