Was sind Overhead-Scanner?| Typen, Eigenschaften und Vorteile
People used to struggle to keep their documents in hardcopy formats. They also had to queue up at shops to have them photocopied for different purposes. This led to paper piling and increased chances of losing it. Overhead scanners made it possible to store all of our documents digitally, making our lives easier.
What is The Core Technology Behind Overhead Scanners?
Telephotography is the source of scanner technology. The only difference between old and new scanners is that old bulky scanners capture the pages of fixed size, whereas modern overhead book scanners scan pages of varying sizes.
The resolution of telephotography was limited by its large dimensions and high power consumption.
A compact and lightweight device was needed that could process high-resolution images.
An overhead scanner is the best choice if you have books you wish to scan.
Flatbed scanners can cause more damage to your books than overhead scanners. Overhead scanners are also called non-destructive scanning.
What Types Of Overhead Scanners Can Be Used With Old Books?
Before we get into the details of overhead scanners, it is important to be familiar with all options available for scanning books at home.
These are just a few examples of scanners:
- Your cell phone
- Scanners for handheld devices
- Flatbed scanners for specialists
- Overhead scanners
Smartphone as a Scanner
You can also use your smartphone to produce high-quality scans, but they are adequate for multiple paper sizes and large scanning jobs. Can you imagine holding your phone while flipping through six hundred pages carefully? This article will explain how overhead scanners work.
Nobody wants to scan a 600-page book this way. It would be too slow and tedious.
Specialist handheld scanners can also be used in the same way.
They can also be taken to the library with permission from the librarian. It would be difficult to read a large book.
Flatbed Scanners
Due to the possibility of damaging old books, experts do not recommend using a flatbed scanner. If you are willing to remove the spine and cover of the book, this is an exception.
To minimize damage, the edge of the bed has been flattened so that the spine does not open more than 90 degrees. Software built-in compensates for inevitable shadows and curves in the image. There is one problem with using flatbeds on fragile pages. Each page is contacted by the machine.
This can cause wear and stress to the pages. An alternative is to scan the pages without touching them. This is an advantage of an overhead scanner.
What are Overhead Scanners?
Overhead scanners resemble an old-fashioned projector in that the scanner lens is mounted on a stem.
The scanner's lens then scans a dark mat onto which a document is placed. When you press the "scan" button, the scanner moves to a higher position. Overhead models can scan A3 documents as a result of this.
Software for Overhead Scanners
Are you looking at thirty scans with your finger in the lower right corner of the image? Then don't worry; overhead scanners can correct that as well!
We have mentioned that overhead scanners are equipped with image software to compensate for curves and shadows in bound books.
In-built imaging software is also available for overhead scanners. This software has been specifically designed to work with books. This software corrects the curvature of the spine.
Flattening algorithms are used to ensure that scanned pages retain the same quality as if they were pressed flat.
Different Overhead Scanners Have Different Functions
Foot pedals are an optional feature that allows you to take a scan by tapping your foot.
This will increase the efficiency of the entire process. To start the scan, you carefully turn the page. When you find your groove, this can be very relaxing and enjoyable.
This is the ultimate holy grail. While the machine flips the pages, you can do something more enjoyable. This option is not available for commercial use. It's possible that the cost will drop in the future, but it is currently too expensive for home use.
Larger libraries may have overhead scanners of high quality that can be used to scan old books and manuscripts. Scanners for commercial use can be very different from those intended for home use. It has a more industrial appearance. It may take many hours of training for librarians and archivists to learn how to use it properly. These are less likely to be made available to the public.
The Best Overhead Scanners Have Many Benefits
Photo restorers now have an essential tool: overhead scanners. Scanners are gentle on photographs that may be significantly damaged or even broken. A graphics technician can repair tears, creases, and other damage to vintage photos once they have been scanned into digital format.
Scanned documents can be sent faster by email than traditional mail or fax. Emailing electronic documents is faster and easier than conventional mail or fax. With the advent of smartphones, tablets and other mobile devices, the recipients don't even need a computer to view the attachments.
Emailing order forms and contracts reduces the time required to complete deals. Other professions, like physicians reviewing images and charts, also benefit from quicker communication. It is particularly efficient to send a document to multiple recipients, as one message can be sent to many people.
Overhead scanners are used to convert a paper document into a graphic image (or PDF) file. However, an optical character recognition software process, which turns a scanned copy into text, goes a step further. OCR converts numbers and letters from a graphic file into text.
You can search for specific words using a word processor, Adobe Acrobat, or any other software once the document has been converted to text. This saves you a lot of time and effort compared to manually going through pages. Text documents are also smaller than graphics images and take up less space on your hard drive.
Scanners that automatically load data from business cards or other forms into your computer's contacts list save you the time and effort of manually typing. These scanners are compact and portable so that you can bring them along to conventions, meetings, or other events where you anticipate meeting many people. OCR capabilities allow the software to recognize common print styles and convert them into text.
Large-scale organizations that handle a lot of paperwork used to have to store old documents in filing cabinets. Scanners simplify the process by significantly decreasing the amount of space needed to store information.
A CD-R can hold 700MB of data and replace a four-drawer filing cabinet with 10,000 pages. A 100GB Bluray disc can replace 142 of these cabinets. They are also more space-efficient and easier to access electronic documents, which is a significant advantage.
Many people are now able to study or work at home due to the COVID-19 epidemic. It does not mean, however, that you should sacrifice quality. You can increase productivity with portable document scanners.

Scan pages of a book instead of photocopying. This will save you time and money. Overhead book scanners that are quiet and don't disturb others in quiet libraries or employees are the most efficient.
Overhead Scanners are a great tool to use in a shared office environment. You may not be able to use shared scanners and printers due to privacy concerns. During such situations, you can scan with an overhead scanner.
Security and privacy were issues with older scanners as well as desktop scanners. These scanners were robust but not compatible with modern technologies. These scanners were less secure due to privacy concerns.
Software that allows you to quickly and efficiently access data is available in modern overhead scanners. Software-enabled portable scanners reduce human error and make it easier to access data than manual effort.
