Desktop Scanners: Image Quality Evaluation

As author Robert G. Gann explains how to create good scans, he explores such issues as exposure controls, scanning speed, resolution, interpolation, image noise, illumination, color registration and fidelity, and black-and-white output. He also recommends several tests for scanners and provides a glossary of scanner terms and a full-color section of images of sample scans.

The companion CD-ROM comes with sample images, test results, and a spreadsheet for RGB-to-LAB conversion. The book doesn't recommend specific brands or models, but has all the technical detail that a private consumer, corporate buyer, or reviewer needs to make an informed decision on today's scanners. --Kathleen Caster

This is not an ABC book. It is not an advacned, either. You need some technical background to read this book. If you want to buy a scanner or learn how to use scanner, try others.

From chapter 1 to 10, it focus on the product definition. It telds you what kind of scanner should be made for current market. From chapter 11, there are basic theory about scanner and how to tell the image quality.

Too few pictures in this book. Some phenomena is hard to descipt.


Not for beginner or office application. Too technical   December 10, 1998

If you are using scanner solely for pictures and/or graphics, this book may be helpful. There is very little information for office application such as scanning documents and placing in Microsoft Word. Too technical for a beginner.
