PhotoScan asks the user to take four separate images of the printed photo and then puts them together to create a high-resolution digital copy of the image. Usually if one takes a picture of the printed photos, the resulting image is plagued with distortion and glare (especially for the gloss finish). PhotoScan, however, makes use of computational photography to iron out the undesired effects. Thanks to the Automatic edge detection the app crops photos to the proper size and will also be able to set the orientation.
With the PhotoScan app, Google has addressed the problem of digitizing printed photos to a large extent. The Google Photos integration will ensure that your old memories are intact and can be accessed at the tap of a button. The unlimited High-Quality storage on the Google Photos will come to your aid while digitizing the old pictures. PhotoScan is already available for iOS and Android. On a related note, Google has also announced an improved auto enhance feature for Google Photos along with new style filters. Filters like deep blue are useful while capturing images of sea and sky together.
