Book Scanner
February 112010
Book scanning can be described as the process of transfering publications into
electronic images, digital text in addition to electronic books (e-books)
through the use of an image scanner. Electronic books are easily sent out, reproduced, and also read on-screen. Common file formats are usually DjVu, Tagged Image File Format (TIFF) and Portable Document Format (PDF). Optical character recognition (OCR) may be used to alter the raw images of the book into ANSII or some other digital text, that minimizes the file size as well as enables the wording to be reformatted, searched, or processed with other
applications.
A book scanner can be manual or automatic. With a typical commercial graphic scanner, a book is going to be placed on a level glass plate (or platen), after which a light and optical array moves over the book beneath the glass. With the
hands-on book scanners, the principle glass plate stretches towards the edge of
the scanner, which makes it less complicated to line up the book’s backbone. Another type of book scanner aligns a book face upward in a v-shaped frame, and takes a photograph of the pages from above.
