Scanner Pro updates with the new shadow removal algorithm to help you take perfect scans in any lighting and quickly improve the quality of your old scans.

Scanner Pro is Readdle’s powerful scanning app for iPhone & iPad, used by millions of people worldwide. Back in 2009, Scanner Pro created a whole category of digitizing paper with mobile. Readdle still keeps improving the app and implementing new technologies to make sure you always get high-quality scans from your paper receipts, books, and documents.

Today, they are excited to show you the new shadow removal algorithm which helps you make amazing scans in any lighting. Shadow Removal automatically works on a camera while scanning in the Black & White or Color Document mode. You can also improve the quality of old scans via the “Edit” menu in the app.

How Shadow Removal works

Finding perfect lighting to scan a book page or a receipt can be a real pain. When you’re scanning something in artificial light, shadows can make parts of the scan unreadable. And sometimes it’s tricky to avoid casting a shadow with your hand holding a phone above a document. With Scanner Pro, you don’t need to worry about that anymore.

The new algorithm automatically works on a camera and erases shadows when you scan a document in the Black & White or Color Document mode. Just scan everything as you always did before, and technology takes care of the rest.

“We specifically designed this algorithm to remove large and deep shadows. Previously, the app could only erase small shadows and spots. Now, even if a shadow is pretty contrasting and occupies more than 30% of an image, Scanner Pro can deal with it,” says Andrii Denysov, the lead developer at Scanner Pro.

Shadow Removal is now powered by Metal, so you can enjoy a much faster scan processing and improved performance.

With so many scanner apps on the AppStore, Scanner Pro focuses on the quality of scans. This update further leapfrogs Scanner Pro from the competition and sets a new standard. The update is available for free in both Scanner Pro and Scanner Mini.
