Fig. 5 A, Fig. 5 B are the movements for the shield 221 for illustrating the books electronization device 1 of this first embodiment Side view.In the present embodiment, shoot part 211 carries out the facing pages P (page of left and right) of book B whenever user turning pages P Secondary shooting.In the shooting of first time, as shown in Figure 5A, in the state of erecting shield 221, not from light source portion 212 Irradiate and shoot the facing pages P (page of left and right) of book B.Therefore, in the shooting of first time, the facing pages P for only shooting book B is (left Right page).

In secondary shooting, as shown in Figure 5 B, what shield 221 was erected perpendicular to the cord of facing pages P Under state, and in the state of linear irradiation light L of the facing pages P of the book B page of the left and right () irradiation from light source portion 212 into Row shooting.Therefore, in secondary shooting, together with facing pages P (page of left and right), shooting irradiation light L is irradiated to split The irradiation area R of irradiation light L on page P (page of left and right).In addition, the effect about shield 221 is described below.

In the present first embodiment, it according to the difference of the shooting image of first time and secondary shooting image, obtains Along the irradiation area R of the curved irradiation light L of the paper of book B, the curvature (height of paper of the irradiation area R based on irradiation light L Spend the deformation in direction), plane correction is carried out to the shooting image of the facing pages of book B.

In addition, in the present first embodiment, to shoot the facing pages P (page of left and right) of book B in the shooting of first time, And the facing pages P of book B is shot in the state of having irradiated irradiation light L to the facing pages P of book B (page of left and right) in second of shooting The mode of (page of left and right) carries out, but can certainly be opposite shooting sequence.

Fig. 6 A, Fig. 6 B are the perspective views being illustrated to the bending state of the facing pages of book B.In spine portion and holding station 10 contacts, in the case that furthermore the thickness of the paper of page P, hardness etc. are generally uniform, if macroscopic observation, from margin (ridge) portion The variation towards page front end (fore-edge) part, the X-direction shown in Fig. 6 A, Fig. 6 B curvature is divided to become in most of substantially phase As be distributed (converging on defined range).In addition, since the power being applied on the paper is gravity, so the curvature is whole Continuously change.

Therefore, as shown in Fig. 6 A, Fig. 6 B, the cross sectional shape of the Y-direction of book B means even if with the interception of any Y-coordinate It is substantially same shape.That is, can allow for slightly for the paper of the aggregate as microcosmic extremely complex curvature Under conditions of micro- error, if it is known that the curvature distribution in some Y-direction section as representative, then the curvature distribution in other sections Its typical value approximation can be passed through.

In the case where sheet-fed, due to that can have free curvature on two-dimensional surface direction, as a result And the face formed becomes complicated three-dimension curved surface, but as shown in book B, one end of each page P in the fixed situation of ridge part, by It is contacted on the other end and ground plane, therefore such condition can be applied.

Therefore, in the present first embodiment, the facing pages relative to book B, the top (or lower section) of Xiang Shu B one at shine The irradiation light L of aplysia punctata.But in order to improve precision, the irradiation light of a plurality of threadiness can be irradiated, it is also contemplated that Y-direction X-direction, the netted irradiation light of the intersection of Y-direction are irradiated in bending.

Fig. 7 A is being irradiated on the facing pages of book B in the books electronization device 1 for indicate this first embodiment The perspective view of the irradiation area R of irradiation light L, Fig. 7 B are the shapes for indicating irradiation area (curve) R of acquired irradiation light L Concept map.Originally, it is generally desirable to, in the case where the irradiation light L from light source portion 212 is irradiated on the facing pages of book B, such as Shown in Fig. 7 A, becomes the irradiation area R of a curved irradiation light L of the facing pages P along book B and be taken.This is because Straight line is only taken when being shot by capturing element from surface, but if then being taken by shoot part 211 from tilted direction shooting Therefore curve as shown in Figure 7 B, can be taken along irradiation area (curve) R of the curved irradiation light L of facing pages P.At this In first embodiment, the curvature (deformation of the short transverse of paper) of the irradiation area R based on irradiation light L, to the split of book B The shooting image of page P carries out plane correction.

Fig. 8 is the concept map for illustrating the method for the shooting image export curvature according to this first embodiment.In the past (for example, Japanese Unexamined Patent Publication 2016-53580) proposes following method: in advance using the wavelength of the light from light source portion 212 as spy Fixed wavelength, the light source portion will be come from through the capture apparatus of the filter of the wavelength by being equipped with only selectivity by additional setting 212 light separates from shooting image and carries out shape presumption.But in this configuration, although having by once shooting energy Enough shooting correction images and the advantages of being corrected image, but due to needing additional capture apparatus, the big of equipment can not be ignored The rising of type, cost.

Therefore, in the present first embodiment, as shown in figure 8, in the shooting of first time, to the split page P of book B (page of left and right) is shot, and in secondary shooting, has irradiated irradiation light L in the split page P (page of left and right) to book B In the state of, together with the irradiation area R of the irradiation light L on paper, the split page P (page of left and right) of book B is shot. In this way, two kinds of images are continuously shot, and according to the difference of these images, the irradiation being taken along on the curved paper of paper of book B The image of the irradiation area R of light L, the curvature of the irradiation area R based on irradiation light L carry out the image of the facing pages of book B flat Face correction.

Fig. 9 to Figure 12 is the concept map of function for illustrating the shield 221 of this first embodiment, effect.As above It is described, in the present first embodiment, linear irradiation light L is irradiated on the paper of facing pages.At this point, in bookbinding edge (binding edge) is divided nearby to lead to the problem of.In the part, the angle of paper becomes the subvertical shape of angle relative to holding station 10 State, therefore as shown in figure 9, irradiation light L reflects on paper, it is projected on the page of opposite side.

Therefore, as shown in Figure 10, the bookbinding rim portion (binding edge) of paper is nearby by mutual scattered reflection light irradiation (diagram Oblique line portion 30).Therefore, it is impossible to correctly determine the irradiation area (shape of the irradiation light L of the bookbinding rim portion (binding edge) of paper Shape) R, there is a possibility that acquirement to curvature will generate error.In the case where being only irradiated to unilateral page, do not occur The problem, but in the case where the paper to facing pages is irradiated and shot, need to eliminate the problem.

Therefore, in the present first embodiment, as the page for avoiding the opposite side to the bookbinding rim portion (binding edge) of paper Scattered reflection light countermeasure, book B margin partial insertion shield 221 and shot.As shield 221, it is Inhibit reflection as far as possible, preferably as close possible to the tone of black and the lacklustre material of dumb light.

In addition, being taken into the figure shot by the shoot part 211 being disposed over if 221 slight curvature of shield As in, the paper of the shadow into shield 221 can not be taken.Therefore, which needs by with a degree of The material of rigidity is formed.In addition, as shown in figure 11, it is excellent in the case where shield 221 to be inserted into the bookbinding rim portion of book B Phase selection is vertically upright for the irradiation light L from light source portion 212.In this way, passing through the margin partial insertion shield in book B 221, as shown in figure 12, it can prevent scattered reflection light from reaching the page of opposite side.

In addition, the height of shield 221 is also important.Scattered reflection light is produced in the bookbinding rim portion (binding edge) of paper It is raw.If the height of shield 221 is lower than the highest point of curved page, there are scattered reflection light reach opposite side page can It can property.It is therefore preferable that the height of shield 221 is higher than the highest point of curved page.Height by making shield 221 is higher than curved The highest point of bent page can prevent scattered reflection light from reaching the page of opposite side as shown in figure 12.

In addition, the highest point of curved page is dependent on the thickness (weight) of the paper of page P, the intensity of book waist, number of pages etc..It can The height of shield 221 is determined to envision the highest point of page in advance, or also be can be set to and can be replaced shield 221, that is, Prepare the different shield 221 of a variety of height, the shield 221 of appropriate height is used according to the highest point of curved page.

Figure 13 and Figure 14 is for illustrating that the books electronization in the books electronization device 1 of this first embodiment acts Flow chart.Firstly, user loads book B in holding station 10, and initial page is split, according to the rule of the information processing terminal 200 Fixed application program indicates to shoot to books electronization device 1.The CPU308 of books electronization device 1 judges whether there is to use by oneself The shooting at family indicates (step S10).Then, without shooting instruction ("No" of step S10), CPU308 is in step S10 is standby.On the other hand, in the case where there is shooting from the user instruction ("Yes" of step S10), CPU308 passes through shooting Portion 211 carries out the shooting of first time, and shooting image is stored in RAM303 (step S12).

Next, the information processing terminal 200 instruction setting shield 221 (step S14) of the CPU308 to user.Books electricity The CPU308 that son makeup sets 1 judges whether to be provided with shield 221 (step S16) by test section 307.Then, it is detecting Provided with ("No" of step S16) before shield 221, CPU308 is standby in step S16.

The bookbinding rim portion of book B is arranged according to the instruction from books electronization device 1 in shield 221 by user, from The information processing terminal 200 is provided with to the notice of books electronization device 1.(the step when detecting provided with shield 221 The "Yes" of S16), CPU308 irradiates linear irradiation light (step S18) from light source portion 212.Then, CPU308 passes through shoot part 211 carry out secondary shooting, which is mapped with the shooting image of first time and is saved (step Rapid S20).

Then, CPU308 judges whether the electronic disposal of book B terminates, that is, judges whether there is the finger of end from the user Show (step S22).Then, in the unclosed situation of electronic disposal of book B ("No" of step S22), CPU308 is to user The information processing terminal 200 indicate page turning (step S24).Later, return step S10 repeats above-mentioned processing.

User receives the instruction of the page turning from books electronization device 1, and manual page turning is split by lower one page, again root 1 is set according to the defined application program instruction books electronic masking of the information processing terminal 200 to be shot.

Later, books electronization device 1 only shoots the split of book B in each user's page turning in the shooting of first time Page P (page of left and right), in secondary shooting, in the state that shield 221 is erected perpendicular to the cord of facing pages P Under, the facing pages P (page of left and right) one from facing pages P (page of left and right) irradiation irradiation light L of 212 pairs of light source portion book B, with book B It rises, shoots the irradiation area R of the irradiation light L on facing pages P.Then, by the shooting image of first time and secondary shooting figure It is saved as being mapped.

Then, at the end of the electronic disposal of book B, if there is end from the user instruction (step S22's "Yes"), then variable p is reset to 0 (step S26) by CPU308.Variable p is to lead for counting to each page progress curvature Out, the count value of page when plane correction based on curvature.Next, variable p is added 1 to be incremented by (step S28) by CPU308.That is, At this, point variable p is " 1 ", indicates first page.

Then, CPU308 is obtained from the shooting image of first time and the difference of secondary shooting image according to page p The irradiation area R of irradiation light L exports curvature (step S30).Then, the curvature of CPU308 export page p and the front and back page of this page of p The variation (step S32) of curvature.In addition, in the case where initial page or last page, since there is no front and back page, therefore export with The variation of the next page or prevpage.

Then, CPU308 judge derived from curvature variation whether within the limits prescribed (step S34).Then, exist Derived from curvature variation within the limits prescribed in the case where ("Yes" of step S34), CPU308 be based on derived curvature, Plane correction (step S36) is carried out to the shooting image (the shooting image of first time) of this page of p.

Then, CPU308 judges whether terminated (step S42) to all pages of plane correction processing.Then, to complete The plane correction of portion's page is handled in unclosed situation ("No" of step S42), and variable p is added 1 by CPU308 return step S28 It is incremented by, the page of process object is promoted into one page, repeats above-mentioned processing.

On the other hand, the variation of derived curvature not within the limits prescribed in the case where ("No" of step S34), Curvature of the CPU308 based on front and back page is come the curvature (step S38) of calibration page p.More specifically, preferably to obtain front and back page The median (average value) of curvature or to front and back page curvature carry out linear interpolation mode calibration page p curvature.Then, CPU308 carries out plane correction (step based on the curvature after correction, to the shooting image (the shooting image of first time) of this page of p S40)。

Then, CPU308 judges whether terminated (step S42) to the plane correction processing of whole pages, to whole pages In the unclosed situation of plane correction processing ("No" of step S42), variable p is added 1 to be incremented by by return step S28, by processing pair The page of elephant promotes one page, repeats the above.

On the other hand, in the case where the plane correction processing to whole pages has terminated ("Yes" of step S42), CPU308 Terminate the processing.

In addition, in the present first embodiment, preservation, curvature based on shooting image in books electronization device 1 Export, curvature carry out plane correction, but not limited to this, it can also terminate in the shooting for shooting each page or whole pages every time Time point, by for the first time, secondary shooting image be sent to the information processing terminal 200 of user, and in whole shooting knots Shu Hou, the export that curvature is carried out in the information processing terminal, the plane correction based on curvature.

According to above-mentioned first embodiment, the paper of facing pages when to illuminated irradiation light L and not illuminated irradiation The paper of facing pages when light L is shot, and the difference of the shooting image based on both sides, extraction is irradiated on the paper of facing pages Irradiation light L irradiation area R, the shape of the irradiation area R based on the irradiation light L extracted exports the curvature of facing pages, Based on the curvature of the derived facing pages, the shooting image of the paper of the facing pages shot when to not illuminated irradiation light carries out flat Face correction.In this case, the uniform image that plane correction is independently implemented with the state of paper can be obtained.

In addition, according to above-mentioned first embodiment, it, can be more easily since irradiation light is set as straight line Export the curvature of facing pages.In addition, can shooting image more easily to the paper of facing pages carry out plane correction.

In addition, according to above-mentioned first embodiment, when irradiating irradiation light and shooting the paper of facing pages, perpendicular to The bookbinding rim portion of facing pages and the laminal shield 221 of position insertion of the illuminated irradiation light from light source portion.At this In the case of, it can prevent scattered reflection light from reaching the page of opposite side, the uniform image for implementing plane correction can be obtained.

B. second embodiment

Then, second embodiment of the present invention is illustrated.

In addition, composition, structure of books electronization device 1 of second embodiment etc. are identical with first embodiment, because This is omitted the description.In this second embodiment, irradiation light is not irradiated to whole pages and shot, with defined page Interval is executed without irradiation light and the shooting twice for having irradiation light, based on the curvature according to derived from the difference of two shooting images, into The plane correction for the image that row takes.On the other hand, (secondary shooting of irradiation light is not irradiated for arbitrary page Page), based on the song according to derived from the difference without above-mentioned irradiation light and two shot twice the shooting image for having irradiation light Rate and the curvature for exporting this page, the plane correction based on the image that the curvature is taken.This is because in general, between page Curvature follow do not significantly change but the continuous rule of thumb, by reduce shoot number, the whole processing time can be shortened, Especially shoot the required processing time.

Figure 15 and Figure 16 is the flow chart for the movement for illustrating the books electronization device 1 of this second embodiment.It is first First, user loads book B in holding station 10, initial page is split, according to the defined application program of the information processing terminal 200 to The instruction shooting of books electronization device 1.The CPU308 of books electronization device 1 judges whether there is shooting instruction from the user (step S50).Then, without shooting instruction ("No" of step S50), CPU308 is standby in step S50.Another party Face, in the case where there is shooting from the user instruction ("Yes" of step S50), CPU308 carries out first by shoot part 211 Shooting image is saved in RAM303 (step S52) by secondary shooting.

Then, CPU308 judges whether current page is correcting captured object page (step S54).As described above, this In two embodiments, executed with defined page interval without irradiation light and the shooting twice for having irradiation light, according to two shooting images Difference export paper curvature.For example the default setting is the intervals of page five, the intervals of page ten etc. at defined page interval, and can be by User is set as arbitrarily being worth.Then, (the step S54 in the case where current page is not correcting captured object page "No"), CPU308 indicates page turning (step S66) to the information processing terminal 200 of user.Then, CPU308 returns to step S50 is repeated the above.That is, being transferred to the shooting action of the first time to lower one page without secondary shooting.

On the other hand, in the case where current page is correcting captured object page ("Yes" of step S54), CPU308 to The information processing terminal 200 at family indicates the setting (step S56) of shield 221.The CPU308 of books electronization device 1 passes through inspection Survey portion 307 judges whether to be provided with shield 221 (step S58).Then, (the step before detecting provided with shield 221 The "No" of S58), CPU308 is standby in step S58.

The bookbinding rim portion of book B is arranged according to the instruction from books electronization device 1 in shield 221 by user, from The information processing terminal 200 is provided with to the notice of books electronization device 1.(the step when detecting provided with shield 221 The "Yes" of S58), CPU308 irradiates linear irradiation light (step S60) from light source portion 212.Then, CPU308 passes through shoot part 211 carry out secondary shooting, which is mapped with the shooting image of first time and is saved (step Rapid S62).

Then, CPU308 judges whether the electronic disposal of book B has terminated, i.e., whether has the instruction of end from the user (step S64).Then, in the unclosed situation of electronic disposal of book B ("No" of step S64), CPU308 is to user's The information processing terminal 200 indicates page turning (step S66).Later, return step S50 repeats above-mentioned processing.That is, being transferred to pair The shooting action of the first time of lower one page.

Later, books electronization device 1 is in each user's page turning, in addition to correcting captured object page, for the first time Shooting in the facing pages P of book B (page of left and right) is shot and is saved, without irradiation light L is irradiated to the split of book B The secondary shooting shot on page P (page of left and right).On the other hand, books electronization device 1 is to correcting captured pair As page (for example, page five interval) is in the shooting of first time, the facing pages P (page of left and right) of book B is only shot, in secondary bat In taking the photograph, in the state that shield 221 is erected perpendicular to the cord of facing pages P, from the facing pages P of 212 pairs of light source portion book B The page of left and right () irradiation irradiation light L, together with the facing pages P (page of left and right) of book B, the irradiation to the irradiation light L on facing pages P Region R is shot, and the shooting image of first time and secondary shooting image are mapped and are saved.

Then, if the electronic disposal of book B terminates, that is, there is the instruction ("Yes" of step S64) of end from the user, Then variable p is reset to 0 (step S68) by CPU308.Variable p is to carry out the export of curvature, based on song to each page for counting The count value of page when the plane correction of rate.Next, variable p is added 1 to be incremented by (step S70) by CPU308.That is, becoming in the time point Measuring p is " 1 ", indicates first page.

Then, CPU308 judges whether page p is correcting captured object page (step S72).It then, is not correction in page p In the case where the object page of shooting ("No" of step S72), variable p is added 1 to be incremented by by CPU308 return step S70, by processing pair The page of elephant promotes one page.That is, in the case where not being correcting captured object page curvature can not be exported at this stage, therefore jump Cross processing.

On the other hand, in the case where page p is correcting captured object page ("Yes" of step S72), according to the first of page p Secondary shooting image and secondary shooting image exports curvature (step S74) from the irradiation area R of irradiation light L.Then, CPU308 carries out plane correction based on shooting image (the shooting image of first time) of the derived curvature to this page of p and saves (step Rapid S76).

Then, CPU308 judges whether the export of the curvature to whole correcting captured object pages, plane correction terminate (step S78), (step in the export of the curvature to whole correcting captured object pages, the unclosed situation of plane correction The "No" of S78), variable p is added 1 to be incremented by by return step S70, and the page of process object is promoted one page, repeats above-mentioned processing.

Later, the page of process object is one by one promoted, curvature is exported to whole correcting captured object pages, based on leading Curvature out carries out plane correction to the shooting image (the shooting image of first time) of this page of p and saves.On the other hand, for not It is the page of correcting captured object page, is skipped without any processing.

Next, variable p is reset to 0 (step S80) by CPU308, and adds 1 to be incremented by (step S82) variable p.That is, At this, point variable p is " 1 ", indicates first page.

Then, CPU308 judges whether page p is correcting captured object page (step S84).It then, is that correction is clapped in page p In the case where the object page taken the photograph ("Yes" of step S84), due to being the page of the export that curvature has been carried out, plane correction, because This CPU308 judges whether the export of the curvature to the whole pages for not being correcting captured object, plane correction have terminated (step S90).Then, in the export of the curvature to the whole pages for not being correcting captured object, the unclosed situation of plane correction Variable p is added 1 to be incremented by by ("No" of step S90), return step S82, and the page of process object is promoted one page, is repeated above-mentioned Processing.

On the other hand, in the case where page p is not correcting captured object page ("No" of step S84), CPU308 is based on To the curvature of the correcting captured object page before and after page p, the curvature (step S86) of page p is exported.More specifically, preferably to take It obtains the median (average value) of the curvature of the correcting captured object page of front and back or linear interpolation is carried out to the curvature of front and back page Mode export the curvature of page p.Then, CPU308 is based on derived curvature, carries out plane correction simultaneously to the shooting image of this page of p It saves (step S88).

Then, CPU308 judges whether the export of the curvature to whole correcting captured object pages, plane correction have tied Beam (step S78), (step in the export of the curvature to whole correcting captured object pages, the unclosed situation of plane correction The "No" of rapid S78), variable p is added 1 to be incremented by by return step S70, and the page of process object is promoted one page, repeats above-mentioned place Reason.

After, the page of process object is one by one promoted, to it is whole be not correcting captured object page, based on before it The curvature of correcting captured object page afterwards exports the curvature of each page, and is carried out based on shooting image of the derived curvature to each page Plane correction simultaneously saves.On the other hand, correcting captured object page is skipped without any processing.

Then, (the step in the case where the plane correction processing to the page other than whole correcting captured objects has terminated The "Yes" of rapid S90), CPU308 terminates the processing.

In addition, in this second embodiment, preservation, curvature based on shooting image in books electronization device 1 Export, curvature carry out plane correction, but not limited to this, each page can also shot every time or tied in the shooting of whole pages The time point of beam sends first time and/or secondary shooting image to the information processing terminal 200 of user, and in whole After shooting, the export of progress curvature, the plane correction based on curvature in the information processing terminal 200.

According to above-mentioned second embodiment, executed with defined page interval without irradiation light and the bat twice for having irradiation light It takes the photograph, the curvature of the difference export paper of image is shot according to two, the derived curvature is based on, the image taken is carried out flat Face correction, on the other hand, for arbitrary page (not carrying out the page for having secondary shooting of irradiation light), based on according to no irradiation Light shoots curvature derived from the difference of image with two shot twice for having irradiation light to estimate the curvature of this page, is based on The curvature deduced, the plane correction of the image taken.In this case, the processing time can be shortened, can be incited somebody to action The image rectification for shooting paper is uniform (without the image of incongruity in the page of front and back).

C. third embodiment

Then, third embodiment of the present invention is illustrated.

In addition, composition, structure of books electronization device 1 of third embodiment etc. are identical with first embodiment, because This is omitted the description.In this third embodiment, similarly to the second embodiment, executed with defined page interval without irradiation light With the shooting twice for having irradiation light, the curvature of the difference export paper of image is shot according to two, on the other hand, in the curvature In the case that variation is more than defined range, the curvature for changing the page more than defined range of above-mentioned curvature is discarded, and under One page executes the curvature for shooting the difference export paper of image according to two without irradiation light and the shooting twice for having irradiation light.? In this case, can prevent curvature from significantling change and the error of plane correction becomes larger.In addition, the original significantlyd change as curvature Cause, consider the page of different paperys mix, every page be printed with different attribute (text, photo, black and white, colour etc.) etc. and The case where reflectivity on the whole significantlys change.

Figure 17 and Figure 18 is the flow chart for the movement for illustrating the books electronization device 1 of this third embodiment.It is first First, user loads book B in holding station 10, initial page is split, from the defined application program of the information processing terminal 200 to book The instruction shooting of nationality electronization device 1.The CPU308 of books electronization device 1 judges whether there is shooting instruction (step from the user Rapid S100).Then, without shooting instruction ("No" of step S100), CPU308 is standby in step S100.Another party Face, in the case where there is shooting from the user instruction ("Yes" of step S100), CPU308 carries out first by shoot part 211 Shooting image is saved in RAM303 (step S102) by secondary shooting.

Then, CPU308 judges whether current page is correcting captured object page (step S104).Defined page interval example Such as the default setting is the intervals of page five, the intervals of page ten, and can be set by the user to be arbitrarily worth.Then, current page not It is ("No" of step S104) in the case where correcting captured object page, CPU308 indicates the information processing terminal 200 of user Page turning (step S126).Then, CPU308 returns to step S100, repeats the above.That is, without secondary shooting, It is transferred to the shooting action of the first time to lower one page.

On the other hand, in the case where current page is correcting captured object page ("Yes" of step S54), CPU308 to The information processing terminal 200 at family indicates the setting (step S106) of shield 221.The CPU308 of books electronization device 1 passes through Test section 307 judges whether to be provided with shield 221 (step S108).Then, before detecting provided with shield 221 ("No" of step S108), CPU308 is standby in step S108.

The bookbinding rim portion of book B is arranged according to the instruction from books electronization device 1 in shield 221 by user, from The information processing terminal 200 is provided with to the notice of books electronization device 1.(the step when detecting provided with shield 221 The "Yes" of S108), CPU308 irradiates linear irradiation light (step S110) from light source portion 212.Then, CPU308 passes through shooting Portion 211 carries out secondary shooting, which is mapped with the shooting image of first time and is saved (step S112).

Then, CPU308 is obtained from the shooting image of first time and the difference of secondary shooting image according to this page The irradiation area R of irradiation light L exports curvature (step S114).Then, CPU308 judges compared with the curvature of derived prevpage Whether the variation of curvature is in defined range (step S116).Also, compared with the curvature with prevpage at the variation of curvature In the case where defined range ("Yes" of step S116), derived curvature is mapped with the page and saves by CPU308 (step S118).

On the other hand, (the step in the case that variation of curvature is more than defined range compared with the curvature with prevpage The "No" of S116), the curvature of this pages such as CPU308 judges due to above-mentioned significantlys change, by the discarded (step of derived curvature Rapid S120).That is, this page is excluded from correcting captured object page.Then, lower one page is set as exporting curvature by CPU308 Correcting captured object page (step S122).

In any case, whether CPU308 judges whether the electronic disposal of book B has terminated, i.e., have from the user The instruction (step S124) of end.Then, in the unclosed situation of electronic disposal of book B ("No" of step S124), CPU308 indicates page turning (step S126) to the information processing terminal 200 of user.Later, return step S100 is repeated above-mentioned Processing.That is, being transferred to the shooting action of the first time to lower one page.

Later, books electronization device 1 is in each user's page turning, in addition to correcting captured object page, only carries out Primary shooting is shot and is saved to the facing pages P (page of left and right) of book B.On the other hand, for correcting captured object Page (for example, the intervals of page five) shoots the facing pages P (page of left and right) of book B, in the shooting of first time at second Shooting in, in the state that shield 221 is erected perpendicular to the cord of facing pages P, from pair of the 212 couples of book B in light source portion It opens a page P (page of left and right) irradiation irradiation light L and is shot.Then, from according to first time shooting image and secondary bat The irradiation area R export curvature for taking the photograph the irradiation light L of the difference acquirement of image, by the shooting image of first time and secondary shooting Image is mapped with curvature and is saved.

In addition, being more than rule in the variation for comparing curvature with the curvature of prevpage to curvature derived from correcting captured object page In the case where fixed range, it is judged as due to certain and the curvature of this page significantlys change, derived curvature is discarded, and will Lower one page is set as exporting the correcting captured object page of curvature, and the export of curvature is carried out to the new page.

Then, if the electronic disposal of book B terminates, that is, have end from the user instruction (step S124's "Yes"), then variable p is reset to 0 (step S128) by CPU308.Variable p is to lead for counting to each page progress curvature Out, the count value of page when plane correction based on curvature.Next, variable p is added 1 to be incremented by (step S130) by CPU308.

Then, CPU308 judges whether page p is correcting captured object page (step S132).It then, is not correction in page p In the case where the object page of shooting ("No" of step S132), variable p is added 1 to be incremented by, will handled by CPU308 return step S130 The page of object promotes one page.That is, in the case where not being correcting captured object page curvature can not be exported at this stage, therefore Skip processing.

On the other hand, in the case where page p is correcting captured object page ("Yes" of step S132), CPU308 is based on Derived curvature in step S114 carries out plane correction to the shooting image of page p and saves (step S134).Then, CPU308 Judge whether the export of the curvature to whole correcting captured object pages, plane correction have terminated (step S136), to complete In the export of the curvature of the correcting captured object page in portion, the unclosed situation of plane correction ("No" of step S138), return To step S130, add 1 to be incremented by variable p, the page of process object is promoted into one page, repeats above-mentioned processing.

Later, the page for one by one promoting process object exports curvature to whole correcting captured object pages, based on export Curvature plane correction is carried out to the shooting image (the shooting image of first time) of this page of p and is saved.On the other hand, to not being school The page of the object page just shot is skipped without any processing.

On the other hand, the case where the export of the curvature to whole correcting captured object pages, plane correction have terminated Under ("Yes" of step S136), variable p is reset to 0 (step S138) by CPU308, by variable p add 1 be incremented by (step S140).

Then, CPU308 judges whether page p is correcting captured object page (step S142).It then, is that correction is clapped in page p In the case where the object page taken the photograph ("Yes" of step S142), due to being the page of the export that curvature has been carried out, plane correction, because This CPU308 judges whether the export of the curvature to the whole pages for not being correcting captured object, plane correction have terminated (step S148).Then, in the export of the curvature to the whole pages for not being correcting captured object, the unclosed situation of plane correction ("No" of step S148) returns to step S140, adds 1 to be incremented by variable p, the page of process object is promoted one page, in repetition The processing stated.

On the other hand, in the case where page p is not correcting captured object page ("No" of step S142), CPU308 is based on To the curvature of the correcting captured object page before and after page p, the curvature (step S144) of page p is exported.More specifically, preferably to take It obtains the median (average value) of the curvature of the correcting captured object page of front and back or linear interpolation is carried out to the curvature of front and back page Mode export the curvature of page p.Then, CPU308 is based on derived curvature, carries out plane correction simultaneously to the shooting image of this page of p It saves (step S146).

Then, CPU308 judges that the export of the curvature to the page other than whole correcting captured objects, plane correction are It is no to have terminated (step S148), it is not finished in the export of the curvature to the whole pages for not being correcting captured object, plane correction In the case where ("No" of step S148), variable p adds 1 to be incremented by, the page of process object promoted one page by return step S140, Repeat above-mentioned processing.

After, the page of process object is one by one promoted, to the whole pages for not being correcting captured object, based on its front and back Correcting captured object page curvature, export the curvature of each page, and carry out based on shooting image of the derived curvature to each page Plane correction simultaneously saves.

Then, (the step in the case where the plane correction processing to the page other than whole correcting captured objects has terminated The "Yes" of rapid S148), CPU308 terminates the processing.

In addition, in this third embodiment, the preservation of shooting image, curvature are carried out in books electronization device 1 Export, the plane correction based on curvature, but not limited to this, each page can also shot every time or in the shooting knot of whole pages The time point of beam sends first time and/or secondary shooting image to the information processing terminal 200 of user, and in whole After shooting, the export of progress curvature, the plane correction based on curvature in the information processing terminal 200.
