Scanning quality of the portable document scanners

1, Determining the appropriate scanning method

The document scanner or portable scanner can scan pictures, text and photos, etc., scanner that are not with the same scan purposes has its different scanning methods. Open the scanner driver interface, you can find the program provides three scanning options, the "Yes or NO" method applies to black and white originals; "Grayscale" is suitable for both text and graphics drawing text proofs, scanning of the type having a plurality of integrated text and pictures gradation; "Photo" suitable for scanning colorful photos, it is a mixture of red, green and blue channels for multi-level sampling and storage. Before scanning, be sure the documents are to be scanned on the basis of the target, the selection of a suitable scanning method scans enables you to achieve a higher role.

2, Optimize the document scanner resolution

The higher the scanning resolution,the more clear the picture, but you need to take into account the resolution of the output device , if you set the picture resolution beyond the capacity of the document scanners, then clear picture can not be printed out, and it simply takes up more disk space, there is no practical value. Thus the selection of the proper scanning resolution is very necessary. After scanning sizes can be reduced significantly by downsizing the pictures. For example, let's do a 600dpi scanning with 4 × 4-inch picture, in the version of the program in its group it can be  reduced to 2 × 2 inches, then it's a resolution of 1200dpi.

3, Set the proper file size

Whether the goal is to scan text, picture or still photo, after the scanner outputs pictures, the size is directly related to the file size scale picture of the size, and therefore we probably set a good file size scales when scanning. In general, the best portable scanner can preview the original proofs calculated when active file size, file size calculation but know more will help you make the right selection in the process of scanning documents and determine the scanning resolution. The formula binary picture file is: a straight-scale horizontal scale × × [2 (scan resolution) / 8]. The formula colorful drawing file is: a straight-scale horizontal scale × × [2 (scan resolution) / 3].

4, Set up scanning parameters for the document scanner

The best scanner from the pre-scanned pictures are scanned according to the scanning system default parameter values, and for different scan targets and scanning methods are not the same, the role can not be the same. Therefore, we in order to achieve a higher quality picture scanning, can use artificial means to adjust parameters such as brightness grayscale and if the colorful picture is too bright or too dark, you can drag the slider after slider on the brightness, changes in brightness. If the brightness is too high, the picture will look white; brightness is too low, too dark. Probably you drag the brightness slider, so that the brightness of the picture can be moderate. Like the other parameters, you can adjust according to the same method to carry out part of the amendment until the self-satisfaction of a visual effect stops. Always, a good scan picture probably try to do without and then picture processing software for more adjustments can be satisfied with the printout, and closest to the print quality.

5, Storage and load scanning software

Sometimes, we in order to get the best color and scanning contrast, first do low-resolution scanning, open it in Photoshop, and do the color and improve the contrast of a curve on Photoshop. Storage curve and load back scanning software, your document scanner will now use this color correction curve to establish a very good high-resolution file. If you use a class like color gamut size scan several pictures, you can apply the same curve, but you can always store the curve, and then base on demand load to them.

6, find the best scanning area on a glass plate for the office supplies

In order to achieve optimum scanning quality picture, we can find the best scanning area of ​​the document scanner, and then scan the target drop in demand here, to get the best and most fidelity picture effect. Detailed search process is as follows: First, the scanner is set to active or tacit condition, check all the region, followed by a low resolution, and scan a blank, white or opaque block proofs; then use a professional picture processing software Photoshop to open the comp, using the mean value of the software instructions (Equalize menu items) on proofs for disposal, after disposal we will be able to see the scanner where there are cracks, stripes, black spots. We can print this document, cut out of the best areas (that is, the most stable region), we then set the best pictures.

OCR software and its application in document scanners

OCR (Optical Character Recognition) document scanner software refers to the situation where the electronic device (e.g., portable scanner or digital camera) check characters printed on paper, by detecting the dark light pattern to determine the shape, then through the shape of the character recognition translating the text into computer process ; that is: ensure the text data is scanned, and then via the image file analysis and processing to get the text and layout information. How to debug or use auxiliary information to improve the recognition accuracy is the most important issue of OCR, the noun ICR (Intelligent Character Recognition) is thus produced. The measuring indicators of a good or bad performance OCR system are: rejection rate, friendly error rate, recognition speed, user interface, product stability, ease of use and feasibility.OCRs are mainly used in scanners, for document scanners,portable scanners and some of the best scanners,which are classified as office supplies.

Optical character recognition concept is created in 1929 by German scientist Tausheck, and later an US scientists Handel also proposed the ideas of the use of technology to identify character. The earliest printed Chinese character recognition research is IBM's Casey and Nagy, in 1966, they published the first article on Chinese character recognition using the template matching method to identify the 1000 printed characters.

Early in the 1960s and 1970s, the world began to research on the OCR, and initial research, mostly research is based on text recognition and text recognition is only confined to the digits 0 to 9. For instance, Japan also has a blocked texts,, around 1960 they began to study the basic OCR recognition theory, the initial stage they focus on the digital object, then they began to have some simple products, such as printed text recognition system between ZIP until 1965-1970, ZIP code identifying the message to help the post office as a letter-area operations; thereafter each country has advocated the zip code address writing style.

Early 1970s, Japanese scholars began to study Chinese character recognition, and did a lot of work. Chinese study in OCR technology started late, they only began to identify numbers, letters and symbols to in their studies in the 1970s, the late 1970s they started to study Chinese character recognition, till 1986 they entered a substantive character recognition stage, many research institutions have launched a Chinese OCR product. Early OCR software, due to various factors and product recognition rate, failed to meet the actual requirements in the application of scanner industry for portable scanners,document scanners,office best scanners. Meanwhile, the high cost of hardware and with the running is slow, they failed to get practical result. Only a few sectors, such as the information sector, the press and publishing units,office supplies have the use of OCR software. OCR after 1986 has made great progress in the Chinese character modeling and identification method; they have the innovation, research and development applications in the system have achieved fruitful results, many units have launched a Chinese OCR products for document scanners. After the beginning of the 20th century, with extensive use of flatbed scanners,OCR document scanner and automation of information and office automation ,they contributed significantly to the further development of OCR technology, the OCR recognition rate and recognition speed are able to meet the majority of users requirement for document scanners and office scanners.

Because of the scanner software's popularity and widespread application, OCR software only needs to be provided with an interface with the portable document scanner, using a scanner driver software, then they can function and work for you.
