The modified module 103 is used for whether the pixel of the image for detecting the acquisition to be corresponded with the coordinate points in plane 21, the acquisition image pixel and the coordinate points in the plane 21 not to it is corresponding when the resolution of the image of the acquisition is changed, the pixel on the image is corresponded with the coordinate points in plane 21.Specifically, when the acquisition image pixel and the coordinate points in the plane 21 not to it is corresponding when the modified module 103 changes the resolution of the image by changing the quantity of image pixel laterally or vertically, when the quantity of the horizontal and vertical pixel of the image is respectively less than or equal to the quantity of the coordinate points of 21 upper side edge of plane and left side, the pixel on the image could be corresponded with the coordinate points in the plane 21.
Further, the modified module 103 detects whether the quantity of the horizontal pixel of the image is more than the quantity of the 21 upper side edge coordinate points of plane, when the quantity of the horizontal pixel of the image is more than the quantity of the 21 upper side edge coordinate points of plane, the modified module 103 reduces the quantity of the horizontal pixel of the image, makes the quantity of horizontal pixel less than or equal to the quantity of the 21 upper side edge coordinate points of plane.The modified module 103 also detects whether the quantity of the vertical pixel of the image is more than the quantity of the 21 left side coordinate points of plane, when the quantity of the vertical pixel of the image is more than the quantity of the 21 left side coordinate points of plane, the modified module 103 reduces the quantity of the vertical pixel of the image, makes the quantity of vertical pixel less than or equal to the quantity of the 21 left side coordinate points of plane.
In other embodiments, user can anticipate the resolution of image on storage device, electronic installation or cloud server, the pixel and the coordinate points in plane 21 for making image is corresponded, so as to the image that the memory element 11 is stored is the one-to-one image of coordinate points on pixel and plane 21.
The control module 104 contacts the position that a reference point is located in the plane 21 for when the plane 21 is positioned on the magnetic scanning device 1, controlling the magnetic read/write head 12.Specifically, user can be positioned over the plane 21 on the magnetic scanning device 1 manually, and click " starting scanning " option being shown on display unit 14, the operational control magnetic read/write head 12 of the control module 104 response user is moved, when the magnetic read/write head 12 senses an induction apparatuss, the control module 104 further controls the position at the contact of magnetic read/write head 12 induction apparatuss place, wherein, the corresponding coordinate points in induction apparatuss position are reference point.In the present embodiment, the reference point is the coordinate points for being provided with induction apparatuss in the corresponding coordinate points of 21 4 vertex positions of the plane, and the reference point position is that the magnetic read/write head 12 starts to scan the position of the plane 21.In other embodiments, four reference points are may include in the plane 21, induction apparatuss are provided with the corresponding coordinate points of four vertex positions, four reference points are respectively the corresponding coordinate points of four vertex positions, and the control module 104 can control the magnetic read/write head 12 and contact arbitrary reference point.
The input module 105 is for generating the signal of telecommunication for reflecting the photographed image-related information according to the image for getting, and the signal of telecommunication for reflecting the photographed image-related information is input into the magnetic read/write head 12.Wherein, the technology for converting the image into corresponding electric signal is technological means commonly used in the art, therefore be will not be described here.In the present embodiment, the relevant information of the image includes the pixel value and positional information of each pixel of the image.
The magnetic field generating module 106 is for when the signal of telecommunication for reflecting the photographed image-related information passes through the magnetic read/write head 12, controlling the magnetic read/write head 12 and produce a magnetic field corresponding with the signal of telecommunication.Wherein, as the magnetic field is produced based on the signal of telecommunication for reflecting the photographed image-related information, therefore, the magnetic field also reflects the relevant information of the image.
The image forming module 107 is used to controlling the magnetic read/write head 12 to start the motion scan plane 21 from the reference point position, the magnetic powder 20 in plane 21 is made to be magnetized under the influence of a magnetic field and produce relative movement, so as to form the image roughly the same with the image of the acquisition.Specifically, the image forming module 106 controls the magnetic read/write head 12 and starts along the at the uniform velocity motion scan of the plane 21 plane 21 from the position of the reference point, under the action of a magnetic field that the magnetic read/write head 12 is produced, magnetic powder 20 in plane 21 is changed into magnetized state from demagnetized state and band is magnetic, simultaneously, there is polarity with magnetic magnetic powder 20 and can attract each other and assemble, and adsorb the upper surface 210 in the plane 21.
Specifically, as the magnetic field that the magnetic read/write head 12 is produced reflects the relevant information of the image, and each pixel of the image has the coordinate points in a plane 21 to correspond to therewith, then from the beginning of the image slices vegetarian refreshments corresponding to 21 reference point of plane, based on image slices vegetarian refreshments and the one-to-one relation of 21 coordinate points of plane, all pixels point of the image is scanned up in the plane 21 successively.For example，When the image is black for the color of black white image and magnetic powder 20，Those magnetic powders 20 are gathered in the corresponding coordinate points position of pixel with pixel value on image for #000000，I.e.，Magnetic powder 20 is gathered in the coordinate points position with the color of image corresponding to the pixel of black，With pixel value on image for #FFFFFF the corresponding coordinate points position nonmagnetic powder 20 of pixel or only a small amount of magnetic powder 20，I.e.，With the coordinate points position nonmagnetic powder 20 corresponding to the pixel that the color of image is white or only a small amount of magnetic powder 20，Therefore，The distribution of those magnetic powders 20 is substantially identical for the distribution of the pixel of black with color on the image，So as to form the image roughly the same with the image，And as the upper surface 210 of the plane 21 is transparent，User can pass through the image that the upper surface 210 sees the formation.Complete in the magnetic read/write head 12 scanning, when the image forming module 106 controls the magnetic read/write head 12 and leaves the plane 21, the magnetic powder 20 in the plane 21 is in remnant magnetism state, to form the image roughly the same with the image so as to remain in that.
In another embodiment, the magnetic scanning device 1 may also include a supporting part（Do not show in figure）, the supporting part is used to carry the containment vessel 2, and now the image forming module 106 does not control the magnetic read/write head 12 and moves, but controls the supporting part and at the uniform velocity move, so that the magnetic read/write head 12 scans the plane 21.In other embodiments, the containment vessel 2 also can be directed at the magnetic read/write head 12 by user manually, and at the uniform velocity move the containment vessel 2 manually, so that the magnetic read/write head 12 scans the plane 21.
This erases module 108 for the image formed in plane 21 is erased.Specifically, control 12 motion scan of magnetic read/write head of module 108 plane 21 of erasing, so that the magnetic powder 20 in plane 21 demagnetizes, magnetic powder 20 after demagnetization loses magnetism and cannot assemble, the upper surface 210 in plane 21 cannot also be adsorbed, so as to the image that the magnetic powder 20 in the plane 21 is formed is erased.
