What is the image contact sensor?
Image contact sensor (CIS) scans the materials in close proximity, rather than using mirrors to bounce light on the image sensor inside the device. For example, in a surface scanner, for example, the image sensor is directly below the glass, as close as possible to the medium in the scanner deposit. These devices can be more efficient than older scanning techniques, but also tend to create lower quality images. The compromise can be acceptable with some scans and settings. The contact image sensor provides scanning at One and One ratio, without image enlargement or other distortion. These life -size scanning may include documents, three -dimensional objects and materials such as textiles that may need to be evaluated by a scanner.
This technology includes some benefits for manufacturers and users. It can be compact, which is useful for mobile scanners and devices that must fit into compact areas. It is also highly efficient and is usually cheaper to produce than similar productionskty. LEDs use less energy than other light sources and can be turned off and on between use. Unlike the scanners used by older forms of lighting, there is a device that uses a contact image sensor, ready for immediately and may not be heated.
The disadvantage is the lower image quality. Documents created with a contact image sensor can have a narrower range of colors and lower resolution. Three -dimensional objects can also be more difficult to scan, as the device works best with materials in close proximity. Shading and other artifacts can develop in the picture when the technician works with materials that do not lie flat against the scanning bed.
Product developers who focus on NTACT image sensor technology also work on ways to improve technology. Improving image quality is the topic of research on some companies that create their heads of contactHo image and integrated devices. Like other technology, it can proceed quickly and the newer equipment tends to offer users the greatest benefits. Consumers who are interested in technology may want to examine to determine what types of products are currently on the market, and when companies are likely to publish new editions that could have better quality.
