What is not a very good scan of a book to digitize?
PS The book "Fundamentals of the language for designing digital equipment Verilog" Solovyov V.V.

Answer 1

all "digitization" works around pattern recognition by the program. if the scan is bad, then she will not see anything on it. in general, fine reader seems to be one of the best

Answer 2

The scan was taken from here, in DJVU www.twirpx.com/file/1598132 ?
If you try to recognize it - with a fine reader, the newer the version, the better. But still get ready, if the scan is not very good, it will take about a month of editorial work.
