digitize text

hello

my project is to take photos of the pages of a book with my digital camera and then perform OCR (optical character recognition) on the photos using ABBYY Finereader program, in order to convert the images to editable text

can you tell me please how can I
1) eliminate the shadows at the edges of the pages
2) eliminate the reflections from the light at the glossy paper of the pages
3) eliminate skew distortion (that is produced because the page curves or because the camera is placed at the center of the document and thus the text at edges is distorted)
4) increase contrast between black characters of the text and white background of the page and make white of the page, true white, and black of the characters, true black

thanks

anyone?
