Object needs to take multiple scan, to ensure that scan module is all contacted with the region for needing to scan, for side
Just image mosaic is carried out to obtain the preferable complete image of picture quality, simplified follow-up image procossing and splicing
Difficulty, when long-pending larger sweep object takes multiple scan over there, it is desirable to the length by sweep object as far as possible
Side or short side start, and according to order from top to bottom or from left to right, uniform speed scanning is carried out to sweep object,
And ensure that all regions to be scanned can be scanned.
Scanning shortcut 40 is connected with the processor 10, for when receiving the open command of user,
The scan module 30 is controlled to open by the processor 10, quickly to start the scan module 30
Scan function.
In a particular application, the scanning shortcut can use the volume key of mobile communication terminal, Menu key,
The physical buttons such as return key or virtual key, or two physical buttons are applied in combination to realize soon
Scan function is opened in victory.
In a preferred embodiment, the embedded back side for being arranged on the mobile communication terminal of the scan module
Or sideways, scanning window is provided with the scan module corresponding position on the Mobile communication terminal casing body,
It is described scanning window be used for printing opacity so that the scanning light beam of scanning light source can be radiated on sweep object, together
When sweep object reflection reflected light can also be touched formula imaging sensor reception.
