What equipment is good for scanning old family photos?

A general household flatbed scanner can be used for scanning.

However, the disadvantages of this type of scanner are long warm-up time and slow scanning speed. A photo may take about 1 minute, but the advantage is high accuracy. Recommended brands: Canon, Epson, HP.

Another way is to use a photo scanner. The disadvantage of this type of scanner is that it is prone to reflections, but it is fast and can easily scan 20 or more pictures in one minute. Recommended brand: Chengzhe Technology (CZUR).

What kind of scanner is good?

What brand of scanner is good? Today I will tell you some little knowledge that you don’t know! The following is what I have compiled for you Which brand of scanner is easy to use and related content about the scanner. Hope it helps you!,

What is a scanner?

A scanner is an input device for a computer. Its function is to convert pictures, photos, films, documents and other written materials into written documents. The appearance of the material or object is scanned and input into the computer, and a file is saved. In fact, the scanner has become the third most important computer input device after the keyboard and mouse.

Scanners come in various forms, such as black and white scanners and color scanners according to color; handheld scanners, flatbed scanners and roller scanners according to scanning methods. Flatbed scanners are widely used, powerful, and affordable, and have been widely used in many fields such as graphics and image processing, electronic publishing, advertising production, and office automation.

As a new and important input device, scanners are widely used. Its function is exactly the opposite of that of a printer. It is to input graphics and text symbols on paper, film, etc. into the computer.

The top ten brands of scanners

1. Canon (founded in Japan in 1937, the world's leading comprehensive group producing imaging and information products)

2 , Zhongjing MICROTEK (domestic scanner brand, famous domestic imaging product export enterprise, Zhongjing Technology Co., Ltd.)

3. Tsinghua Unigroup Thunis (Beijing in 1988, one of the top 100 electronic information companies in China, National high-tech enterprise, Ziguang Co., Ltd.)

4. BenQ (founded in Taiwan in 1984, a large professional group company in the field of optoelectronic digital media and network communications)

5. HP HP (1939 United States, Fortune 500, 1939 California, China Hewlett-Packard Co., Ltd.)

6. Founder (Beijing in 1986, China's famous trademark, China's famous IT company, Peking University Founder Group )

7. Epson (founded in Nagano, Japan in 1942, a famous brand and a global leader in the field of digital imaging)

8. Hanwang HW (founded in Beijing in 1998, a national torch project Key high-tech enterprise, Hanwang Technology)

9. Hongguang Avision (1991, Hsinchu, Taiwan, world leader in the production of image input equipment, Shanghai Hongcai Technology Co., Ltd.)

10. Fujitsu Fujitsu

Zhongjing is the world’s leader in scanners. It has a long product line and relatively guaranteed quality, so it can be given priority. HP and purple light are also pretty good. The resolution of mainstream scanners on the market has now reached 2400Dpi, and the home-use models among famous brand products only cost about 300 yuan. When purchasing, please note that it is best to buy a CCD scanning head rather than a CIS scanning head. In addition to making the product very thin and light, CIS is unsatisfactory in other aspects, such as low resolution, failure of one tube in the LED array and the entire array will be scrapped, and the inability to scan originals with uneven surfaces. Just buy a business-grade scanner for 1,500 yuan. However, if it is only used in general, the effect is no different from that of household grade. Just figure it out yourself.

How to choose a high-speed scanner

1. Scanning format

The maximum scanning format of high-speed scanners is generally divided into A3 and A4 (downward compatible, the smallest format Can scan business card size paper). A3 format high-speed scanners are much more expensive than A4 format high-speed scanners, so you need to choose based on actual application requirements. If the documents you need to scan are basically A4, considering the price, you can choose A4 format. That’s it. If you need to scan a lot of documents in A3 format, you only need to choose an A3 format machine.

2. Scanning speed

The scanning speed of high-speed scanners generally ranges from more than 20 pages to more than 100 pages per minute. However, from a price point of view, the price of the machine increases for every 10 pages increased in scanning speed. The increase is a lot, so you need to make a selection based on actual application requirements, and make a rough calculation based on the amount of scanning that each machine needs to scan every day.

3. Image output

High-speed scanner image output is generally divided into two categories: color (including color, grayscale, black and white) and black and white (including grayscale, black and white) , when other parameters are basically the same, color is more expensive than black and white machines, so the choice needs to be based on actual use requirements. If the documents that need to be scanned only need to save black and white images, then you can choose a black and white scanner. If you must insist on If the color of the file is original (such as red-headed documents, fresh seals, etc.), you can only choose a color scanner. Color pictures generally take up a lot of storage space, so you need to consider storage issues. In order to reduce storage pressure and transmit reading faster within the network, even if you choose a color high-speed scanner, you need to see whether the scanner has the automatic color and black and white recognition function (when scanning a color page, it outputs a color image, when scanning a color page Output the black and white image when reaching the black and white page, so as to maintain the original appearance of the file and reduce the storage space as much as possible.

In addition, it depends on whether the high-speed scanner has MultiStreamTM dual data stream output (black and white color, black and white). Grayscale), this function is very useful in file full-text search applications. The scan outputs a black and white and a color or grayscale image at the same time. The black and white image is used for identification, and the color or grayscale image is used for archiving.

4. Image enhancement processing

When purchasing a high-speed scanner, you should check whether the high-speed scanner can meet the requirements for image enhancement processing, such as: automatic cutting, correction, and black removal Special attention should be paid to image quality when using functions such as edges, multi-color filtering, and automatic recognition of color/black-and-white originals. The same parameter settings will produce different image quality on different brands of machines. Of course, better image quality is better for some brands. If a high-speed scanner needs to achieve relatively good image quality, it needs to add a Kafax card. The Kafax card is expensive and will undoubtedly increase the cost.

5. Paper thickness range

This parameter reflects this. The machine's paper passing ability and large range indicate better adaptability to paper.

In short: the choice of a high-speed scanner must first be based on the format required for the actual application, and then the machine with the appropriate speed (based on Calculation of the amount of scanning you want to complete every day), if a single machine needs to work continuously for more than 8 hours a day, it is best to choose a consumer-grade high-speed scanner. The paper feeding structure of the machine and the daily throughput and machine attention weight recommended by the manufacturer are more important. The parameters can basically easily judge the stability, failure rate and durability of the machine. In addition, it will be helpful to learn more about the image processing effect, failure rate and service life of various brands of scanners from other users. What needs to be reminded is: when purchasing a high-speed scanner, you need to confirm the formal warranty card and after-sales service guarantee. Because the high-speed scanner is different from other ordinary electronic products, it is a combination of electronics and machinery, and requires an after-sales service guarantee to ensure your work. Not affected.

Almighty Scanner is better. Almighty Scanner has many functions such as image scanning, file conversion in different formats, text extraction, file modification, etc. Some functions require payment, and some simple functions can be used casually. Scanner Almighty is really helpful. It can scan originals of different formats and materials into high-definition electronic documents. At the same time, it uses the text recognition function to extract the text of the original paper contract and write a new contract, so that you don’t have to draft it from scratch every time.

Which brand of scanner is better

Question 1: Which brand of scanner is the best? Canon (world brand, leading brand, first in market share in Japan in 1937)

MICROTEK (domestic scanner brand, top ten scanner brands)

Tsinghua Unigroup Thunis (founded in Beijing in 1988, a national key high-tech enterprise, one of the top ten scanner brands)

Epson (founded in Nagano, Japan in 1942, a global leader in the field of digital imaging)

BenQ (founded in Taiwan in 1984, a world brand, one of the top ten scanner brands)

HP (1939 in California, USA, a world brand, one of the top ten scanner brands)

Hanwang HW (established in Beijing in 1998, a national high-tech enterprise, one of the top ten scanner brands)

Question 2: What brand of scanner is good? For well-known brands, Epson is the first choice, followed by Canon. There is also the domestic Zhongjing, which is also an old brand of scanners. It manufactures optical instruments, so the scanning quality is not inferior to Japanese brands at all.

In terms of price, it is actually about 300 yuan. Because no matter how high-end it is, it costs more than a thousand yuan for a high-end scanning product. Generally among low-end and mid-range products, there is not much difference in scanning performance between scanners priced at 500-600 yuan and scanners priced around 300 yuan.

Scanners priced at 500 to 600 yuan only have a few more functions, and they all have useless functions that you may never use in your lifetime. For example, scanning a document and then sending it via email is a very boring function, and then it adds unnecessary prices to you.

What’s more important is that the technology of scanner products has long been completely mature, and there is no big technical difference between the same grade, different price points and different brands. So there is no need to spend more money just for some external factors. For a scanner, good results are the key, and everything else is just a cloud.

So it is more important to buy one that works well than one that has many functions.

Specially speaking about the type, it is best to buy a scanner that uses CCD photosensitive parts. CCD scanners are thicker and slightly larger, but they must have good scanning results, especially fuller colors.

Nowadays, it is generally recommended that you buy a scanner with CIS or LED photosensitive parts on the market. The only advantage of this kind of scanner is that it is relatively small and can be made very thin. But the scanning effect is not good.

Question 3: Which brand of scanner is better? First, you need to understand the most fundamental difference between EPOSN and Canon’s low-end machines:

EPSONV10 uses CCD as the scanning element Device scanner. The advantage is that it can scan three-dimensional objects. For example, the middle seam of a book can be scanned very clearly. To put it simply, you can scan very clearly even if you leave the scanning platform.

The disadvantage is that the CCD element is relatively thick, but V10, V100, V200, and V350 have all been improved and become thinner and lighter than other brands of CCD.

The Canonlide series uses CIS components, which have the advantage of shorter warm-up time after power-on and faster scanning of pure black documents, but the color effect is not ideal, and the difference between CIS and CCD is opposite. Yes, there is a black shadow around the image scanned on the computer after the CIS leaves the scanning platform. Cannot be changed.

The scanning resolution is used to enlarge the image and has little to do with the clarity. Scanning text at 300dpi and color photos at 600dpi are completely OK. To scan with good and clear colors, it mainly depends on the optical density (I won’t explain this here)

All all-in-one machines use CIS because they are small in size and are used for copying, so the resolution is Not high either. (There are several CCD models but they are very expensive). It's the kind that digital enthusiasts like.

Do you need to use it for film scanning? Want to take out the old negatives at home and play with them? Okay~! Instead of developing the film from the previous SLR camera, I scanned it into the computer and made PS modifications to achieve the effect I wanted. (Many top photography enthusiasts use 120, etc.)

Question 4: Never buy which brand of scanner is better, compare prices and choose Canon (world brand, leading brand, No. 1 in market share) 1, Japan in 1937)

Zhongjing MICROTEK (domestic scanner brand, top ten scanner brands)

Tsinghua Unigroup Thunis (Beijing in 1988, national key high-tech enterprise , top ten scanner brands)

Epson (founded in Nagano, Japan in 1942, a global leader in the field of digital imaging)

BenQ (founded in Taiwan in 1984, a world brand, Top Ten Scanner Brands)

HP HP (founded in California, USA in 1939, the world's top ten scanner brands)

Hanwang HW (founded in Beijing in 1998, a national high-tech enterprise, one of the top ten scanner brands) (Best scanner brand)

Question 5: Which brand of scanner is better for office use? I like to use HP’s, the quality is also good. I have used the printer in my office for three years, and it has never been used except for the grinder once. Not broken

Question 6: Which brand of scanner is better? Nowadays, high-speed scanners are used. They have all the functions of scanners, are faster and have more complete functions than scanners. I recommend the Zhelin brand as a better brand. For details, go to Zhongguancun Online to see the detailed parameters and introduction

Question 7: I want to buy a scanner, which brand is better? Most of the current scanners are similar and regular. Everything from the manufacturer has quality assurance.

High-end professional ones are different again

Question 8: Which brand of scanner has the best image quality? Of course it is Kodak, which has extremely high image processing capabilities;

In terms of overall hardware performance, I recommend the small scanner. Japan's Fujitsu has a stable operating process;

If you look at cost-effectiveness, you can also look at Taiwanese and domestic brands. For home tablets, Epson and Canon are also good.

Question 9: Which brand of scanner is better? At present, the brands with good sales volume on the market mainly include Microtek, HP, Thunis, etc. Zhongjing has been the leader in scanners in the world for many years, HP focuses on high-end products, and Ziguang is favored for its excellent Chinese character recognition software. The brand with the highest sales volume in each quarter of 2006 is still Zhongjing.

Nowadays, Zhongjing’s product with a resolution of 2400DPI and a color depth of 48 bits is just over 300 yuan, which is a good value for money compared to non-brand-name scanners that cost 220 yuan. You can buy a scanner with film scanning function for 800 yuan.

Famous brand products have advantages in quality assurance and after-sales service. Moreover, since the structure and technology of the scanner are relatively simple and the profit is not high, there is no risk of counterfeiting.

So, it is recommended to buy Zhongjing products.
