Today Google came out with a new app called PhotoScan that will scan your old photo collection. Like just everyone, I have stashes of shoeboxes inherited from parents full of pictures. Some were scanned in a scanner, back when I had one that was compatible with a computer. More recently, I’ve used scanning apps like Readdle’s Scanner Pro and Scanbot. These de-skew the photographs of the photos that your phone takes but the resolution’s is not always the best and there can be some glare from overhead lights, especially when you’re working with a glossy original pictures.
Google’s approach cleverly stitches together multiple photos. It uses a process much like their 360-degree photo app: you start with a overview photo. Once taken, you see four circles hovering to the sides of the picture. Move the camera to each and it takes more pictures. Once you’ve gone over all four circles, Google stitches these five photos together in such a way that there’s no perspective distortion.
What’s remarkable is the speed. I scanned 15 photos in while also making dinner for the kids. The dimensions of all looked good and the resolution looks about as good as the original. These are good results for something so easy.
