Since 3.0 release DocScanner for iPhone has had a limited text recognition feature that made documents searchable. We ended up limiting the feature since the quality of the OCR was limited. Now we have found set of workarounds and the next release of DocScanner is going to have full OCR support.
Obviously the OCR will make some errors. Quality of OCR is quite good with the 3GS. With 3G and older it will make more errors. Known limitations at the moment include:
- No support for copy & paste (expect to have it soon)
- Poor quality with 3G and older
- OCR supports only Latin alhpabets
As you can see in the attached PDF the recognized text is behind the the scanned image. Therefore the document is always good to print and read, even if the OCR has made errors. Try to select and copy text to see how OCR has done the job.
In near future we will make our best to include support for Japanese and improve user interface to make it fast to use DocScanner for capturing text from the real world to be attached to emails, SMS messages and anywhere with copy & paste. Please find the attached PDF that demonstrates how it works with A4 document scanned with 3GS.
