It takes approximately the same time as for shooting a photo with your camera. Since this device class works with CMOS area sensors it only takes a fraction of a second for capturing the image. CMOS devices shoot the originals at one go, scanners, however, sample the original line by line. It is usual to designate these devices as scanners, however it is not applicable in the technical aspect. Although there are only a few numbers of CMOS scanner manufacturers, but they are available under uncountable brand names in the market. Basically they are boxes with an integrated camera, which which you can photograph slides, negatives and paper photos. Simple CMOS scannersĬMOS scanners are a quite new species on the market, they have been available in a larger quantity since approx. On this page we demonstrate you which benefits and deficits the specific scan precdures have and what you should consider when buying a scanner. Slides and negatives are extremely demanding originals the majority of all scanners available on the market can capture the analogue image information only with clear deficits.
The device classes determine essentially for which application a device is optimized thus conclusions can be made for the capability of a scanner.
If you intend to digitize your slides and negatives you have to make a principal decision between different classes of scanners.
