Fig. 2 is the scanning process schematic diagram of portable scanning device of the present invention.
Among the figure: 1, Master Scanner; 2, sweep speed register; 3 housings; 4, display screen; 6, pad; 7, rectangular light electric transition element.
Embodiment
Rely on the basic general knowledge of this area below, in conjunction with the accompanying drawings the present invention be further described:
Because it is portable and smart that portable set should design, so the effective scanning length of Master Scanner 1 is shorter, generally is designed to 3CM to 10CM, therefore, adopts traditional simple scanning pattern can't scan the bigger original copy of breadth (as the A4 breadth) as far as possible.Therefore, the present invention has adopted a kind of brand-new scan pattern, i.e. free angle reciprocating motion type scanning.
As shown in Figure 2, the portable scanning device is positioned on the original copy, original position is the PosA place in the drawings, and Master Scanner 1 is pressed close to original copy always and is in shooting state.Manual then mobile portable scanning means reciprocatingly moves along the route shown in the dotted line among the figure, moves to the PosB place among the figure at last.Scanning process is a coherent process, and Master Scanner 1 should keep pressing close to original copy always in the scanning process, can not separate with original copy.In scanning process, as long as guarantee that the movement locus of Master Scanner 1 covers the whole breadth of original copy, concrete sweep circuit is unrestricted, wherein Sao Miao circuit allows and overlaps.In scanning process, the original scan-data of the whole process of Master Scanner 1 record; Simultaneously, sweep speed register 2 is also taken the camera data of writing scan velocity characteristic synchronously.
Adopt the rectangular light electric transition element in the sweep speed register 2, the optical alignment transducer that uses in its operation principle and the known photoelectricity/laser mouse is similar, take very little rectangular area by a scale-up version optical imaging system with higher DPI standard, amplify the amount of movement that can obtain scanning position more accurately by the part.And with the collaborative work of a plurality of rectangular light electric transition element, verification each other or get its mean value avoids occurring error.
In sum, in free angle reciprocating motion type scanning process, Master Scanner 1 obtains original image by fixed sampling frequency F1, thereby forms an image array LY, and quantity is n (LY1, LY2, LY3 ... LYn), sweep speed register 2 also obtains the displacement of Master Scanner 1 with respect to original copy by identical fixed sampling frequency F1 simultaneously, thereby form a displacement data array PXY, wherein comprise the displacement on X and the Y both direction, quantity is n (PX1, PY1, PX2, PY2, PX3, PY3, ... PXn, PYn).
The original scan-data that free angle reciprocating motion type scanning is obtained can not simply be connected into complete image because move back and forth in the process, Master Scanner 1 may multiple scanning same position to the original copy, will inevitably produce the redundant data of part.Can be combined to form complete image by image array LY and displacement data PXY by following method:
1. be benchmark with LX1 and PX1, PY1,, as the origin of coordinates, the data among the LY1 be packed in the respective coordinates position of target image with first pixel among the LX1 with the scanning direction of LY1 Y direction as scan coordinate system;
2. contrast PX1, PY1 and PX2, PY2, calculate deflection angle α, displacement MX, the MY of LX2 with respect to LX1, with first pixel setting coordinate among the LX2 is MX, MY, again the data coordinates among the LX2 is rotated by deflection angle α successively and calculates the new coordinate of acquisition, again the data among the LY2 are packed in the respective coordinates position of target image by the coordinate after calculating;
3. follow-up initial data is all done contrast with PX1, PY1 and calculate, repeating step 2, the target image splicing is complete the most at last.
Owing to there is redundant data, a plurality of repeating datas can appear on the same coordinate points of target image, can take three kinds of diverse ways to handle respectively:
1. first impressions are strongest: be as the criterion with the data of filling for the first time, ignore follow-up data;
2. it is main going into after: the data with up-to-date filling are as the criterion, and constantly cover renewal with new data;
3. contrast is calculated: earlier the data of all repetitions are all noted, last whole continuity principle according to image is by accepting or rejecting with the contrast that closes on coordinate.
Scan image can adopt redundant mode or non-redundant mode to preserve:
Non-redundant mode: after original scan-data splicing processing, preserve by normal image file format.
Redundant mode: keep original scan-data fully, do not carry out image processing, can compress processing to file.Because the disposal ability of portable set is subjected to certain restriction, the splicing and the image optimization that may be difficult to competent original scan-data are handled.At this moment, can original scan-data be kept, by computer and special image analysis software original scan-data be handled again, to reach best display effect by redundant mode.
Embodiment 1:
This portable scanning device can embed and be installed in the mobile phone, Master Scanner 1 can be placed the back side of mobile phone, utilizes the hardware and software of mobile phone self to carry out image processing.Can one group of roller 5 or pad 6 be installed at the back side of mobile phone, can on original copy, reciprocatingly move stably in order to guarantee the portable scanning device.
In scanning process, more can utilize mobile phone screen to realize the scan mode of " What You See Is What You Get ".
The scan mode of " What You See Is What You Get " is exactly in scanning process specifically, and the view data of scanning directly is filled in the target image, and target image then is presented on the mobile phone screen and along with the process of scanning refreshes in real time.Like this, the operator can carry out image preview very intuitively; But and the Real Time Observation scan condition, avoid occurring the situation of drain sweep; Or can find as early as possible that interrupting this scanning process than the situation of large deviation, scanning again appears in scanning process.
Embodiment 2:
This portable scanning device can embed and be installed in the computer mouse, utilizes the hardware and software of computer self can carry out image processing.
Because photoelectricity/laser mouse itself promptly contains the optical alignment transducer, can use as sweep speed register 2.Master Scanner 1 is placed the bottom surface of mouse, and scan mode is then basic identical with the mode of normal rolling mouse.Because the design of mouse more meets the characteristic of ergonomics, can be so that the scan operation that moves back and forth be smooth more.In scanning process, also can utilize computer display to realize the scan mode of " What You See Is What You Get ".
More than each embodiment be not to concrete restriction of the present invention, do not breaking away from claims restricted portion of the present invention, can make all concrete modifications to this device.
