Hello ereszet,
The info you provide is fantastic. I just discovered this thread. Thank you!
I travel a lot and imagine bringing along a pocketable digital cam to photo scan magazine articles, and later ocr them, enabling search. I contacted abbyy for any hardware recommendations beyond what you quote above, but they did not want to give any other advice. Previously I've used a C-pen to scan text. Slow and headings go amiss etc. Rather than being at my desk with a tripod and v-cradle, I imagine sitting aboard a plane, taking out the camera to free hand shoot a page of some text I'm reading, using the settings/features abbyy listed. I've got a few basic questions:
1. Capturing images with a handheld camera with image stabilization, (obviously the results wouldn't be nearly as good as with tripod and v-cradle) but do you think it could work? Have you tried hand held photo scanning and later OCR?
2. I wonder, would a wide-angle lens be a help or a detriment? I just noticed I had to be quite far away from the page when taking a picture from a book with a Sony DSC-200 I've got available and a wide angle lens would enable being closer to the page when taking the picture. I have not tried any OCR software.
Thank you for any feedback!
