Why not look at using an open source OCR engine such as Tesseract?
https://github.com/tesseract-ocr/
C# Wrapper for Tesseract
http://www.pixel-technology.com/freeware/tessnet2/
Java Wrapper for Tesseract
https://sourceforge.net/projects/tessocrinjava/

You can use it as a DLL as well with not much effort so no command line necessary. It comes with this out of the box as they say in their release notes. https://github.com/tesseract-ocr/

Thank you for response, I'm looking on this one and it seems the best choice for now.
The one con which I see that it is working quite slow when I try to use big image (full screen camera photo for example).
Can you recommend some alternatives just for comparing?

Microsoft has a great API in their Azure Cognitive Services.
Check the Computer Vision API, which is very simple to use and pretty good performance.

Hope it help you.
