I use my smartphone to scan paper documents.
In an era when dedicated scanners are becoming unnecessary?
Modern smartphone cameras are high performance. This is an iPhone 12 mini, but it has enough performance to be useful as a digital camera. Snap taken with iPhone 12 mini. In some cases, you can take pictures that seem to have a better impression than a mirrorless digital single-lens camera.
For example, the "CamScanner" app. There are iOS and Android versions, but if you shoot a paper document with a smartphone camera, it will semi-automatically shape it.
The left image was scanned with CamScanner. Since the image is oblique, in some cases it may not be possible to scan at the original resolution of the camera. The one on the right was taken with a smartphone camera app. The difference is stark. Both images are from the iPhone 12 Pro Max. Also, this document (which will also appear as a sample) is my bankbook in 1992, and I am currently in the process of digitizing my old bankbook using my smartphone. .
