The flatbed scanner detects the reflection of the light it produces to recreate the color, contrast, and shapes or patterns of that which it scans. While drum scanners still see occasional use, especially when dealing with photographic negatives or other specialty applications, they have been largely superseded by flatbed scanners, which use a flat sheet of glass or another clear material and shined light to capture an image of a document, photo, or object.

The cylinder rotates before a series of optics called photomultipliers which capture the contrasts and colors of the images whirled before them, faithfully recreating the image scanned in detail. The first functional computer linked scanner was drum scanner, a device that uses an acrylic cylinder to which the document or photograph to be scanned is fixed. The image scanner as we know it today, that is, a unit that records images digitally that can be stored and reproduced an indefinite number of times, can be dated back to the middle of the 20th Century. The second unit received the pulses of electricity and used the charge to release blue ink, faithfully recreating the original pattern. In the mid 1850s, Italian physicist and inventor Giovanni Caselli invented the Pantelegraph, an ingenious device that could reproduce simple ink drawings by "scanning" them with an electrically charged stylus which transmitted pulses of electricity to a remote unit via telegraph wire.
VUPOINT PORTABLE SCANNERS REVIEWS UPDATE
While we've removed more 'dated' models and those that are relatively less efficient compared to the latest standards, we've left models that we still think are good options from before this update albeit, in most cases, these models have been demoted or moved to a different position within the list.Īs amazing as it may be to conceive of this today, the forerunner to the now ubiquitous scanner has roots dating back to the middle of the 19th Century. Additionally, the cameras can take photos and videos for documentation, and these models have built-in LED’s and are made to double in function as reading/table lamps, although they are a little more expensive than sheet-fed options. These camera scanners tend to have some sophisticated features like OCR (Optical Character Recognition), TWAIN and SDK, as well as the smart ability to fill in broken edges. We’ve replaced the 1st and 2nd options with a couple of the latest portable camera scanners (the iOChow S1 and iCodis X7) that seem to have cropped up in the last few years and lack the ‘bulkiness’ of traditional sheet-fed portable models. Additionally, we replaced the Doxie Q with the slightly newer and less feature-rich -but more portable - Doxie Go SE. We had to update this list considerably, seeing as many of the models like the Fujitsu ScanSnap and Flip-Pal Wireless were outdated for a category like this with ‘fast-moving’ technology. The Brother DS-940DW makes its debut this year and is one of our favorites due to its balance of price, performance, and overall features. We also removed the iCodis X7 in favor of it newer iteration, the iCodis X9, which has a higher megapixel camera. While the Tango X might be longer, it is a couple of pounds lighter and offers printing capabilities.
Also, we felt if you were willing to carry something of its heft, then you might as well opt for the HP Tango X instead.

During this update, we decided to remove the Raven Pro due its large size and weight that really makes it questionable of whether it should be considered portable or not.
