Hi @delpes,
if you don't set the scanning region on the RecognizerRunnerVeiw, then full camera frames will be scanned. If you want the user to place the camera as close as possible, you should not set the smaller scanning region. You can draw camera overlay rectangle which will suggest where to place the document. You can add overlay as a child to RecognizerRunnerView, like it is done here, or you can include the overlay directly in activity layout.
For setting the minimum char height, you can use method AbstractOCREngineOptions.setMinimumCharHeight, this is height in pixels on the image thet came to recognition. You should experiment with height and see which value gives the best results.

Thanks for your reply.
So the CharHeight is variable/relative to the closeness of the objec the camera and the screen capabilities?

That is true, this is setting for the OCR engine, it only knows about the image which came to recognition.
