How to call a phone number on a picture? How to call a number on a picture without typing it over by hand into the phone app (because it is faster and more convenient that way)?

Like:


phone number on a piece of paper I hold in my hand (like a business card)
on a bill board
on a photo stored on my device


For information, I found the following apps that do or promise the sought functionality:


VisuCaller (payable)
Camera Dialer (not available any more?)
This feature isn’t implemented in iOS. You would probably be fastest to ask Siri to dial the number via dictation if you can see the number and speak it.

Some third party apps have image recognition like iOS does in the notes app when you hand write things or when a PDF can be scanned into searchable / copy able text.

One third party app that has a scanner is Excel - you can take a picture of a paper table and it tries to automate the numbers and text that created the printed table.
