Next, the information that present embodiment is related to is imbedded to move and is described.The information that is present embodiment relates to shown in Figure 2 is imbedded the flow chart of action.As shown in Figure 2, imbed in the action in the information that present embodiment relates to, at first, the information of imbedding image of imbedding object of information is transfused to (S201) to 116 li of information embedding parts.Afterwards, information embedding part 116 is obtained information and is imbedded condition (S202).It is about because of imbedding the information of effect that information obtains etc. that this information is imbedded condition.Information embedding part 116 is accepted or rejected selection (S203) to the mode of being elected in the information embedded mode of plural number, and is notified 111 li of master control part according to the condition of imbedding that is transfused to.S202, S203 will describe in detail in the back.111 li of master control part are controlled input and output control part 113, and will be shown to 105 li of display screens (S204) by the information embedded mode that information embedding part 116 notices are come.
The user confirms the information embedded mode that is presented at 105 li of display screens, and decides embedded mode (S205) by the operation to display screen 105.At this moment, if when the embedded mode of plural number is presented at 105 li of display screens, the user is by selecting to determine embedded mode to one in these modes.Decision by the user to the operation of display screen 105 and the instruction of the embedded mode of importing be situated between and be input to 111 li of master control part by input and output control part 113.Information embedding part 116 is according to the decision of being familiar with embedded mode from the notice of master control part 111.After the embedded mode decision, information embedding part 116 is just imbedded (S206) for the image information of carrying out that is transfused among the S201, and end process.
Below, with reference to flow chart shown in Figure 3, the action that obtains of the information shown in the S202 being imbedded condition is described in detail.When the information of obtaining is imbedded condition, at first, be presented at 105 li of display screens (S301) about the project of checking of the use form of image information.Shown in Figure 4 is the illustration figure of use form assigned picture that is presented at the image information of 105 li of display screens.As shown in Figure 4, the use form assigned picture of the image information that present embodiment relates to is divided into, for the technical routine of the requirement of the image of imbedding information (generation image) with generate the technical routine of the use of image.Also have as the meaning of imbedding the application target of information for the requirement that generates image.The user to each project check beat collude after, press " OK " button of (touching) picture below.Thus, use shape information just to be situated between and be imported into 113 li of input and output control parts by display screen 105.Information embedding part 116 is obtained (S302) by the transmission of master control part 111 and is used shape information.That is the function of display screen 105, input and output control part 113, master control part 111 and information embedding part 116 is as using shape information to obtain means.
Information embedding part 116 is after obtaining the use shape information, and reference is checked project total form corresponding to respectively checking the function of beating the project of colluding, and carries out the total (S303) of checked result.Shown in Figure 5 is the invocation point table (project of checking amounts to form) of checking the function of beating the project of colluding corresponding to above-mentioned.As shown in Figure 5, checking project amounts to form and is beaten the project of colluding and the information of image is imbedded the ranks shape that kind class names such as resulting function (later on as the functional type name) form represent by shown in Figure 4 checking.Then, for respectively checking the project, set point number in necessary function kind class name of colluding of beating.For example, shown in Figure 4 checking in the project, when " not wishing to be copied " project (Q1-1) is beaten when colluding, as shown in Figure 5, in " duplicate and limit ", " inhibition literal ", " necessary field " and kind class names such as " shear resistants ", be assigned with various counting.In other words, shown in the table of Fig. 5, be in order to satisfy this requirement of " not wishing to be copied ", by imbedding information in image, need additional " duplicating restriction ", " inhibition literal ", " necessary field " and functions such as " shear resistants ".
In addition, checking project amounts to form and distributes for counting of each functional type name and be weighted.For example, in distribution that " inhibition literal " kind class name is counted, be assigned with 4 points when colluding the project of " not wishing to be copied " being checked beat, and be assigned with 5 points when colluding " whether differentiate is the original copy document that is printed " project (Q1-3) being checked beat.Thus, respectively checking in the project, can carry out more suitable judgement the function that is required.
Here, functional type name shown in Figure 5 is described in detail." duplicate restriction " is that function that the information that image information is duplicated is imbedded is forbidden in demonstration.There is no particular limitation for embedded mode, goes for the embedded mode of plural number." trace (trace) " is the output device of discriminant information (making model, Mac address, IP address etc.) etc. imbed user ID, document ID, date, to(for) image information.Thus, when leakage of information takes place, just can find the leakaging cause of information." inhibition literal " is to append in the image by the dot pattern with regulation, makes that the figure of regulation or literal can float up when duplicating.Thus, just can carry out the differentiation of original copy document or preventing of forgery." distort detection " and be by the detection information of distorting that will stipulate and append in image information all, and according to having or not this to distort the function of distorting that detection information is come detected image information.That is, should imbed the place of distorting detection information, detect to have or not and distort by distorting detection information.
" attractive in appearance " relates to is by information is embedded in the image information, and how many degree are image information originally visually changed.That is with respect to original image information, degree attractive in appearance influence visually is few more good more.For example, check among the project shown in Figure 4, when " influence to original image will be lacked ", or projects such as " sending to outside the company " checked and beaten when colluding, and functional type name that should " attractive in appearance " promptly is assigned with counts.Be assigned to counting in the functional type name of " attractive in appearance ", can have influence on the information that is embedded in the original image visual/not visible.In the present embodiment, 3 kinds of modes of " visual ", " being difficult to visual " and " not visible " are arranged, according to being assigned to counting of " attractive in appearance " lining, these modes promptly obtain selecting.To describe in detail in the back about mode.
" amount of information " relates to the amount of information of the information of imbedding.In the present embodiment, shown in Figure 4 check to beat collude in the project, jumbo if desired requirements quilt is beaten when colluding when imbedding information, in the functional type name that promptly is assigned to this " amount of information " of counting.Also have, when the amount of information of information is imbedded in the needs minimizing, also can distribute and count." necessary field " relates to respect to original image and imbeds range of information.In the present embodiment, shown in Figure 4 check to beat collude in the project, when the requirement of imbedding range of information when minimizing was beaten and colluded, counting promptly was assigned in the functional type name in this " necessary field ".Also have, when needs are imbedded information on a large scale, also can distribute and count.
What " imbed the time " and relate to is information embedding part 116 needed time when imbedding information in S206 shown in Figure 2.In the present embodiment, shown in Figure 4 check to beat collude in the project, when the requirement of imbedding when the rapid process information of needs was beaten and colluded, counting promptly was assigned in this functional type name of " imbedding the time ".For example, beaten in the situation of colluding, when different identification numbers is paid by each one, just be necessary each one is carried out generation drawing information after the different image processing in the functional type name of shown in Figure 4 " a large amount of transmission ".In this case, if selected to need long information embedded mode, will spend long time to final printing end of output.Short mode just can solve such problem if selection information is imbedded required time.
What " find time " relate to is by with reference to generating image, is used to read the needed time of the information of being imbedded.In the present embodiment, shown in Figure 4 check to beat collude in the project, when extracting the requirement of the information of imbedding rapidly out and beaten when colluding from generating image, counting promptly is assigned in this functional type name of " finding time "." shear resistant " refers to when printing output generates image, shears its output with after the part of paper, with respect to the deleted repellence of the information of imbedding by waiting with scissors.In addition, on electronic data, like this too when shear generating image a part of.For example, when in image information, paying bar code when imbedding information, if after this bar code sheared, it is invalid that the information of being imbedded will become.Therefore, in the present embodiment, shown in Figure 4 check to beat collude in the project, when the ineffective treatment repellence that need imbed information because of the deletion of the part of image requirement beaten when colluding, in the functional type name that promptly is assigned to this " shear resistant " of counting.
What " imbed intensity " and relate to is by growing with reference to generating extraction (success) rate, intersection (interleave) number of times, (make mistakes and correct) odd even (parity) that image reads the information of imbedding.For example, when the image to printing output repeats to duplicate, or the conversion of the image information of electronic data, or when writing filtration (filter) in image information, image originally will degenerate gradually." imbed intensity " even be exactly, whether also can extract the information of imbedding out about from such image that changes.In the present embodiment, shown in Figure 4 check to beat collude in the project, when also needing the information of imbedding to collude for effectively requiring to be beaten when the duplicating of image, conversion etc. are repeated, counting promptly is assigned in this functional type name of " imbedding intensity ".
Below, to shown in the S203 of figure two, recommend the choice of the information embedded mode that uses to select to explain.In the choice of information embedded mode was selected, information embedding part 116 was with reference to the functional type name form under the variety of way of self remembering.Shown in Figure 7 is functional type name form under the variety of way that relates to of present embodiment.As shown in Figure 7, the functional type name form under the variety of way that relates to of present embodiment is the ranks shape of each information embedded mode and functional type name.Then, with respect to each information embedded mode, may provide degree with what " zero ", " △ ", " * " came three sections each functional type names of ground expression.In other words, the functional type name form under the related variety of way of present embodiment is the effect that can obtain in each information embedded mode.That is the functional type name form under the variety of way is as providing functional type name information to be used, and it has remembered function, effect, effect that various information embedded modes can provide.
Here, the example to information embedded mode shown in Figure 7 explains.In the present embodiment, " duplicating control technology ", " visual watermark ", " non-/ be difficult to visual watermark ", " inhibition literal ", " bar code " etc. have been exemplified." duplicating control technology " is for mask (mask) pattern of image by imbedding regulation, limits the technology with the duplicating of the image of paper output.In this embedded mode, owing to above-mentioned specific mask patterns is imbedded easily, so have the easy-on advantage.But then, in order to bring into play the duplicating controlled function, photocopier need have function and exist with ... photocopier corresponding to this technology, or the shortcoming that is compromised etc. of original image attractive in appearance." visual watermark " is to imbed the technology of information by drawing mask patterns in image information.In this mode, (seeing through and handle) because above-mentioned mask patterns can visual cognition, so have the effect that suppresses bad.But then, have the shortcoming attractive in appearance of the original image of infringement.
" non-/ be difficult to visual watermark " is with respect to above-mentioned " visual watermark ", as the term suggests the technology of information is imbedded on ground under not visible or the state that is difficult to be familiar with.For example, in the document image, the technology of the interval shape of 1 literal of change is arranged, or change the technology of the information of imbedding by smile level, frequency etc.In these modes, because the information of imbedding can not or be difficult to do visual cognition, so have the advantage attractive in appearance of not damaging original image.But then, but there is the amount of information that to imbed will be less than the shortcoming of other modes." inhibition literal " is point (dot) pattern of imbedding regulation in original image, can show when being duplicated by photocopier corresponding to the literal of imbedding dot pattern, mark to wait, and represents that it is the technology of duplicating document.The advantage of this mode is the measuring ability that does not need above-mentioned " duplicating control technology ".But then, owing to self be copied, still have the shortcoming attractive in appearance of the original image of infringement.
" bar code " is meant the technology of imbedding the information of figure one patterned in the neutral gear of original image.One dimension figure pattern and X-Y scheme pattern are arranged in this mode.This mode is compared to have with other modes and can be imbedded the advantage that contains much information.But then, its shortcoming is just can delete the information of imbedding easily by shearing figure pattern part, promptly is short of shear resistant.These modes also can make up the mode of plural number to be suitable for outside using separately separately.
When the information embedded mode among the S203 of Fig. 2 being accepted or rejected selection, information embedding part 116 carry out histogramization with reference to the functional type name form under the variety of way to the degree that may provide that is set in each information embedded mode.Fig. 8 is with the figure after the mode B histogramization shown in Figure 7.The resultant conditional information histogram of imbedding of resulting histogram of functional type name form under 116 pairs of bases of information embedding part variety of way as shown in Figure 8 (the functional type name form that may provide) and step S202 carries out shape relatively, and the degree of closeness of its shape is calculated as evaluation of estimate.Shown in Figure 9 is the histogrammic overlay chart of functional type name of imbedding the conditional information histogram and may providing.In Fig. 9, the functional type name histogram that expresses possibility and provide with oblique line.When the degree of closeness of conditional information histogram and the histogrammic shape of functional type name that may provide was provided in evaluation, calculated example was as two histogrammic overlapping degrees.All interior information embedded modes of functional type name form that 116 pairs of information embedding parts are stored under the variety of way all carry out above-mentioned judgement, the embedded mode that evaluation of estimate is surpassed defined threshold is selected (selecting) as the recommendation embedded mode, and the embedded mode of the discontented threshold value of evaluation of estimate is deleted from candidate.Thus, recommend the choice of embedded mode to select to be accomplished.
Shown in Figure 10 is the result that the choice of the recommendation embedded mode among the step S203 of Fig. 2 is selected, and the mode that is shown to 105 li of display screens in step S204 is selected picture.As shown in figure 10, in step S203, be shown from high to low according to evaluation of estimate as the selecteed mode of recommendation embedded mode.At this moment, the characteristics of each embedded mode obtain showing in associated paying as function declaration.Thus, just can help the user to determine final embedded mode, also just can make things convenient for the user to make decision.The user shows according to picture shown in Figure 10, imbeds button by selecting to press (touching) behind the embedded mode, decides embedded mode (S205).That is in the present embodiment, display screen 105, input and output control part 113, master control part 111 and information embedding part 116 also move as information append mode decision means.Also have, when the embedded mode of screen displayed has only 1, can whether suitable by this embedded mode of inquiry.In this case, the user judges whether shown embedded mode is suitable, and operating display 105.The embedded mode that information embedding part 116 is determined according to step S205 is carried out (step S206) information and is imbedded.That is information embedding part 116 moves as the information additional means.
As mentioned above, in the related information embedded mode of present embodiment, the user need just can not provide the image processing apparatus that can easily select the information embedded mode for the knowledge of the information embedded mode of plural number.In addition, the image processing apparatus 1 that present embodiment is related, according to the use shape information of user input, the information that generates the processing of requirement imbed the information purpose or imbed to(for) information etc. is imbedded conditional information.Then, imbed condition, judge the appropriate information embedded mode according to the information that is generated.Thus, just can select to satisfy the user imbeds a plurality of functional type names of requirement to information embedded mode.
For the foregoing description, it is also conceivable that the use shape information of user, the mode in the information embedded mode of being assigned to of directly will counting according to input.This situation has than the foregoing description can make the advantage of handling simplification.Yet, be dispensed to the information embedded mode when directly counting, count when deciding mode according to this, there is the function of Yin Teding only and obtains the selecteed possibility of mode that height is counted.Therefore, user's situation that desired item might be not being met in the function of plural number when information is imbedded.Adopt above-mentioned selection mode just can address this is that.Also have, when user's desired item when information is imbedded relates to 1 functional type name, owing to distribute to the information embedded mode by adopting directly will count, can simple above-mentioned processing, so use to well suitably to distinguish.
In addition, also can corresponding to the content of information embedded mode, decide embedded mode as one by one by with the problem content of checking project shown in Figure 4 to select some projects of checking.In addition, by to the checking to beat and collude of 1 project separately of " to generating the requirement of image " shown in Figure 4 and " generating the purposes of image ", can also make the selection number of embedded mode obtain screening.
Also have, in the step S204 of above-mentioned explanation, though be to show that evaluation of estimate illustrates above the mode of defined threshold, also can just show all modes by evaluation of estimate, or only show the mode that evaluation of estimate is the highest.In addition, in the above description, as shown in figure 10,, also can be to select to estimate the highest mode automatically to come execution information to imbed though be that to imbed with execution information be that example illustrates to select 1 from the mode of plural number.Similarly, even when surpassing the mode of defined threshold and only having one, also can imbed according to this mode execution information automatically.
In addition, in the above description, as shown in Figure 9, be to imbed the conditional information histogram and the histogrammic coincidence degree of functional type name that may provide with calculating, try to achieve evaluation of estimate and illustrate for example.Can adopt as this routine concrete form, the functional type name histogram that may provide satisfies imbeds the ratio of the histogrammic area of conditional information as evaluation of estimate.Other for example in each the functional type name in imbedding the conditional information histogram threshold value is set in addition, the value of representing to be higher than threshold value with " zero ", represent to be lower than threshold value with " △ " but be not equal to 0 value, represent to equal 0 value with " * ", by being to make in 3 stages to imbed the conditional information form with numerical transformation, and the method that compares with functional type name form under each mode shown in Figure 7.Shown in Figure 11 is corresponding to imbedding the histogrammic conditional information form of imbedding of conditional information among Fig. 6.In the example of Figure 11, demonstration be to set the threshold to 3 situation.
In imbedding the conditional information form, when " △ ",, just be judged as and satisfied condition if in the functional type name form under each mode during function corresponding kind " △ " or " zero " by name.And be " zero " in the described form, during function corresponding kind " zero " by name, be judged as and satisfied condition.All functions kind class name to all embedded modes all carries out such judgement, imbeds the satisfaction degree of conditional information by evaluation, just can select recommended information embedded mode.Be, promptly can judge also can also not have the embedded mode of satisfied functional type name from candidate, to delete specifically with having 1 condition with the number of the functional type name that satisfies condition.Other, also can be with the total result who checks project shown in Figure 4, representing transverse axis with the functional type name, when the broken line that forms with counting of being assigned with is represented the longitudinal axis, similarly the functional type name form under each mode is made broken line, by selecting recommended mode with carrying out pattern coupling (pattern matching) after both formulaizations.In addition, in the above description, as shown in Figure 7, though the functional type name form under each mode represents that with 3 stages of " zero ", " △ " and " * " it also can be represented with being same as the numerical value of imbedding conditional information.
In the above description, as shown in Figure 2, original image is imported into 116 li of information embedding parts, imbeds to information and be described till finishing.Here, be imported in the form of 116 li of information embedding parts at image, have, information is imbedded the situation of savings in the document in the HDD110, or situation about being transfused to as print job from host apparatus, and the image that is read as scan components 102 situation about being transfused to.When the savings document in the HDD110 is transfused to, carry out according to the operation of user's display screen 105 or from the order of host apparatus.When carrying out according to the operation of host apparatus, master control part 111 is controlled input and output control part 113 according to the notice of information embedding part 116, is situated between by main frame I/F104, and the display message of displayed map 4, picture shown in Figure 10 is sent in the host apparatus.
When host apparatus is transfused to as print job, similarly, master control part 111 is controlled input and output control part 113 according to the notice of information embedding part 116, is situated between by main frame I/F104, and the display message of displayed map 4, picture shown in Figure 10 is sent in the host apparatus.In addition, because host apparatus has the application software that information is imbedded processing, so also can carry out action same as described above.The image information that generates after information is imbedded goes to carry out image formation after being transfused to image processing part 114.Other, be not to imbed to the original image information of carrying out, also can generate respectively with original image, and generate in the drawing information of image processing part 114 and to make it overlapping in the step and get final product imbedding information.
When original image was transfused to as reading images by scan components 102, user's operating display 105 was when carrying out scanning, and by Fig. 4, picture shown in Figure 10 are shown to 105 li of display screens, the information embedded mode is promptly determined.Other, by the image information after the end of image processing apparatus 114 image processing, also can not be input to 116 li of information embedding parts, but after the information of imbedding is imported into 114 li of image processing parts, according to by the photographed data of scanning engine 102 input with imbed information and come carries out image processing, the image information (the generation image in the above-mentioned explanation) of imbedding information generates by image processing part 114.
Embodiment 2
In embodiment 1, as shown in Figure 4,, the input example of using form is described by beating to collude for the project of checking of plural number.Yet the use for requirement that generates image or generation image shown in Figure 4 might comprise the situation that can not realize simultaneously.When this each other the both sides of the project of contradiction beaten when colluding, exist the possibility that suitable information embedded mode can not get selecting.In the present embodiment, till imbedding obtaining of condition, adopt the form of dialogue just can solve such problem from the information of being input to of using shape information.Also have, the formation of paying same symbol with embodiment 1 is represented the part same or suitable with embodiment 1, and omits its explanation.Shown in Figure 12 is that input, the information of the use shape information that relates to of present embodiment imbeds that condition obtains and the flow chart of action is selected in the choice of information embedded mode.That is, action shown in Figure 12 is corresponding to the action of step S202 shown in Figure 2～S204.
As shown in figure 12, when the related use shape information of input present embodiment, check in the project shown in Figure 4, be included in generating some in the project checked in the image request, be displayed on 105 li of display screens (S1201) as problem project.That is in the present embodiment, the problem project of plural number is divided into plural number and represents.The user keys in questions answer (S1202) by operating display 105 to shown problem input " Yes " or " No ".The answer information that is transfused to is informed to 116 li of information embedding parts from master control part 111.Information embedding part 116 amounts to form with reference to the project of checking shown in Figure 5, answer is quantized (S1203) and generates and imbed conditional information.
After imbedding the conditional information generation, the situation of information embedding part 116 and embodiment 1 is similarly with reference to behind the functional type name form under each mode shown in Figure 7, confirm whether embedded mode is screened to 1 (S1204), when embedded mode screened during to 1 (S1204), just with S204 shown in Figure 2 similarly, screened information embedded mode is shown to display screen 105 (S1205) lining and end process.At this moment, as shown in figure 10, with the speciality of function of showing this embedded mode simultaneously etc. for well.On the other hand, when embedded mode does not have (S1204) when screened, information embedding part 116 is according to the answer (S1202) to foregoing problems (S1201), the problem that will deny of the function that inquiry is difficult to realize with the ability of the problem of contradiction each other or screened embedded mode is deleted from candidate, and notifies 111 li of master control part (S1206) with next problem.Afterwards, moving to embedded mode of S1201 repeated for several times till screened.
As mentioned above, in the input method of the related use shape information of present embodiment, can avoid requiring the problem and the answer of the function of the plural number of contradiction each other, and can suitably select the information embedded mode.Also have, in the above description, though each example of checking input " yes "/" No " in the project is described, other, also can show once the problem of contradiction each other, and from 2 or a plurality of select 1.Further,, show relative importance value, under the situation of the problem that does not show the needed function of inquiry user, can prevent that embedded mode is screened by setting for each problem project (checking project).As the setting of the demonstration relative importance value of problem project, can exemplify will inquiry " duplicate restriction ", the problem that will not wait of the function of " trace ", " inhibition literal " and relevant fail safes such as " distorting detections ", the preferentially form of demonstration etc.
In addition, in the above description, though be screened to embedded mode be that 1 form is described, be not limited to this, also can when screening to a certain degree, show the mode of plural number.For example, also can be as mentioned above, the function of connection fail safe will do not inquired that when screened ends of function of fail safe connection, the embedded mode that demonstration is selected is selected by the user voluntarily according to function introduction shown in Figure 10 afterwards.Other, also can be to set the screening number of targets of embedded mode with number arbitrarily, just go demonstration to get final product to this number of targets when following when screened.
In embodiment 1, be described only obtaining the example of imbedding conditional information according to the use shape information of user's input.In the present embodiment, to the information of the original image that is transfused to by other reference, select the example of more suitable embedded mode to explain.Also have, the formation of paying symbol is similarly to Example 1 represented the part same or suitable with embodiment 1, and omits its explanation.The information that includes the application software that makes document in the image information, or the various information such as information of the text message of document and image self.In the present embodiment, also these information are extracted out as the use shape information, and be increased in the generation of imbedding conditional information.Thus, when alleviating the embedded mode evaluation, in user's the burden, can improve the precision of evaluation more.For example, when comprising the information of the application software that generates original image, according to the characteristic of each application software (during printing blank parts few etc.), the whether suitable difference that has of its embedded mode separately.Its influence is joined among the evaluation.In addition, can consider that also extracting keywords such as " contracts " out from the text message of document infers its purposes, and be increased in the assessment item.
Specifically, when the printing blank is few, can consider in the functional type name in " necessary field " shown in Figure 5, to count by appending to distribute.In addition, when the image number of pages of the original image that is transfused to is many, can consider in the functional type name of " imbedding the time ", to count by appending to distribute.Further, text message as original image, when extracting keywords such as " contract ", " outside maintaining secrecy " out, it is also conceivable that in the functional type name of " duplicating restriction ", " trace ", " inhibition literal " and relevant fail safes such as " distorting detection " and count by appending to distribute to company.As mentioned above, imbedding in the conditional information adquisitiones that present embodiment relates to,, just can alleviate user's burden or select more suitable embedded mode by outside the use shape information of user's input, having added the information that obtains from original image.
Also have, in the above description, outside user's input information (with respect to the answer information of problem project), the information that image information is extracted out is also as using form to be described as example.But, also can be only to decide embedded mode according to the information present embodiment explanation, that extract out from image information.Just can alleviate thus, the burden of user's information input operation more.In addition, can also prevent to cause the selecteed problem of unsuitable embedded mode because of user's information input error.
In embodiment 1, by checking checking of project and beat and to collude, to checking the mode that adds of counting that project amounts to form and be described according to shown in Figure 5 to shown in Figure 4.In the present embodiment, the example that functional type name to the connection fail safe is weighted of should counting when adding explains.Also have, the formation of paying symbol is similarly to Example 1 represented the part same or suitable with embodiment 1, and omits its explanation.As the way to manage of document, the method for setting security level is arranged.Therefore, according to being beaten the project of colluding in the picture shown in Figure 4, with reference to shown in Figure 5 check project and amount to form and count with distribution in, count by considering that security level distributes, just can select embedded mode according to security level.In addition, exceeded the above fail safe of needs, can also prevent to sacrifice other functions of grade attractive in appearance by paying.
When the related use shape information of input present embodiment, at first, set the security level of original image.This setting promptly can be the information that the user imports, also can be by the suppositions automatically such as content of document.Perhaps can also be at first, to infer security level by the project of checking by " generating the purposes of image " shown in Figure 4 beaten and colluded.At this moment, change rank according to for example sending object information.For example, when security level be assigned to " height "/" in "/" low " three sections, the rank of " height " is amounting to form and is distributing when counting with reference to the project of checking shown in Figure 5, for attractive in appearance, imbed function or eliminating that time etc. and fail safe do not have direct relation, or reduce it and (for example count, wait with 50%, 70% of counting of checking that project amounts to that form sets and to do low distribution of counting), count and necessary function in the fail safe added." in " rank the time, just amount to form and distribute and count according to the project of checking shown in Figure 5.During the rank of " low ", reduce with counting of fail safe connection project (same as described above, wait with 50%, 70% of counting of checking that project amounts to that form sets and to do low distribution of counting), and to the distribution of counting of sundry items such as " attractive in appearance ", " imbedding the time ".
By such form, information embedding part 116 just can generate and obtain the conditional information of imbedding corresponding to security level, thereby can select more to meet the information embedded mode of truth.As above explanation in the present embodiment, by changing the distribution form of counting corresponding to security level, makes when security level is high, and fail safe connection function can more obtain obtaining imbedding conditional information with paying attention to.
Also have, outside above-mentioned form, for example, also can in the histogrammic comparison phase of functional type name of imbedding the information histogram and may providing shown in Figure 9, reflect imbedding after conditional information obtains.For example, as shown in Figure 9, when calculating two histogrammic coincidence degree,, just calculate the evaluation of estimate of the coincidence of the functional type name that safety-sensitive correlates if security level be " height ".On the other hand, the functional type name for beyond the fail safe connection calculates the evaluation of estimate of despising the coincidence degree.By this method, just can obtain effect same as described above.In addition, in the above description, be benchmark with the security level, the functional type name of fail safe connection or be much accounted of, or illustrate with being little accounted of.But, be not limited to security level, corresponding to the application target of original separately image, also can consider to pay attention to the form of other functional type names.
In embodiment 1, by the user is checked to beat and colludes the project of checking shown in Figure 4, amount to form according to the project of checking shown in Figure 5, illustrate in each functional type name to be assigned with the example of counting.With respect to this, in the use shape information input method that present embodiment relates to,, make that specific functional type name obtains paying attention to by the kind of input document.For example, contract or invoice etc. are treated by identical on the safety policy generally speaking.For this document,, just can screen function owing to use the possibility of identical embedded mode higher.For example, information embedding part 116 has the such form of Figure 13, and decides the functional type name that pay attention to according to the kind of the document of importing.In addition, also can set form shown in Figure 13 by the user.
Thus, the user needs only the kind of input document, and selects further project to get final product as required.Information embedding part 116 screens embedded mode according to the kind of the document that is transfused to reference to form shown in Figure 13, and the information of using the information of sundry item, being obtained by document, the information that could imbed etc. just can be selected the embedded mode of the best.So, in the related use shape information input method of present embodiment, because the kind of importing document by the user is come the filter information embedded mode, thus just can be when alleviating burden for users, the processing of simplification device.
Other embodiment
Shown in Figure 9 be imbed the conditional information histogram and the functional type name histogram that may provide between comparative result, the original information content of image that comprises the information of imbedding is fastened the existence deficiency in the pass of imbedding information and information embedded mode, and can not find suitable information embedded mode.Even comprise that the original information content of image of the information of imbedding is not enough, take place from the situation of the information of imbedding of guaranteeing the viewpoint of fail safe, have to have to.In this case, information embedding part 116 carries out certain image processing so that it becomes the image of the information of can imbedding according to user's instruction forcibly in original image.By this method, just can carry out the higher information of security level imbeds.This situation will describe in detail in the embodiment 6 of back and embodiment 7.
Also having, in the explanation of the foregoing description 1～embodiment 5, as shown in Figure 1, in the image processing apparatus with sweep unit 102 or print engine 107, is that example is described to have added additional information in original image.But, when additional information being appended in the original image and being stored in the HDD110, or be situated between when being sent in the host apparatus by main frame I/F104, might not need the situation of scan components 102 particularly and print engine 107.Therefore, the image processing method that this explanation relates to, also can realize by general information processor is moved as image processing apparatus, be not limited to particularly have the image read-out of scan components 102, or have the image processing system of print engine 107 and compounding machine thereof etc.
Embodiment 6
Shown in Figure 14 is the composition module figure of information flush mounting 1000 among the 6th embodiment of this explanation.Information flush mounting 1000 among the 6th embodiment can be included in, or is equivalent to 116 li of the information embedding parts of the foregoing description 1～embodiment 5 described image processing apparatus 1.Shown in Figure 15 is the flow chart of all processing of information flush mounting 1000 among the 6th embodiment.Figure 16 describes shown in Figure 15 the flow chart that could imbed judgment processing at step S1503 place in the flow chart in detail.
At first, with reference to Figure 14 the function formation of the 6th embodiment is explained.This explanation execution mode 6 described herein is that the present invention is applicable to the FAX device, and carries out imbedding of information after overlapping additional information in the FAX image.Also have, represent additional information is overlapped onto in the image to imbed information simply below, in addition, represent additional information to imbed information.Being constructed as follows of the 6th execution mode of the present invention shown in Figure 14: the image input part 1401 of scanner etc. and could imbed judging part 1402 and imbed information input unit 1403 and picture editting portion 1404 and information embedding part 1406.Then, the hardware components of FAX device is to be made of not shown memory, CPU etc., above-mentionedly could imbed judging part 1402, imbed information input unit 1403, picture editting portion 1404, information embedding part 1406 is made of software and leave in the memory, brings into play separately function by the execution of CPU.
Below, with reference to flow chart shown in Figure 15, all processing actions of the information flush mounting 1000 of the 6th execution mode are described.
(1) at first, pass through FAX input transfer image (S1501) from image input parts such as scanner 1401, in addition, from imbedding the imbed information (S1502) of information input unit 1403 inputs as additional information.This imbeds information can be that the recipient ID or transmit of conveyer ID, the FAX of FAX does not want any by the secret information of visual cognition etc. in the FAX image of destination output.
(2) after image and the information of imbedding are transfused to, then, could imbed judging part 1402 in the image that is transfused to, judge imbedding the information that is transfused to.This could imbed judgement processing describe (S1503) in the back with reference to Figure 16 in detail.
(3) be judged as at step S1503 place can not imbed the time when imbedding judging part 1402, the picture editting of picture editting portion 1404 with regard to carrying out forcibly that base map is removed, background image is removed etc., make the image (S1504) that can overlappingly be transfused to information to increase blank area, afterwards, information embedding part 1406 is imbedded processing (S1505) to the additional information that is transfused in the image that above-mentioned picture editting portion makes.
(4) in addition, be judged as at step S1503 place can imbed the time when imbedding judging part 1402, just do not carry out the editor of image, information embedding part 1406 is imbedded processing (S1505) to the additional information that is transfused in the image that is transfused to.
Increase blank area though picture editting portion 1404 picture editting such as removes at above-mentioned step S1504 place by base map,, also can adopt the position of image is moved to increase blank Method for Area as this picture editting.This method is by moving figure etc., blank being focused on 1 place (or many places), to guarantee to imbed the needed blank area of data (for example 1cm frame) more.Thus, even in the blank frame of 5mm, can not imbed data the time, also become and to have imbedded data.That is, by a certain content is moved to the left, and the blank frame in left side and the blank frame on right side are lumped together, just can make new 1cm blank frame, thereby can increase the capacity of writing.
Below, with reference to the flow chart of Figure 16, could imbed explaining in detail of judgment processing action to the step S1503 in the flow chart shown in Figure 15.
(1) after this handles beginning, could imbed judging part 1402 at first from the amount of information of the information of imbedding self that is transfused to, with to imbedding the mode that information is imbedded, calculate and imbed amount of information A (S1601), simultaneously, the blank area from the image that is transfused to calculates the amount of information B (S1602) that can imbed amount of information.
With reference to the described processing of embodiment 1～embodiment 5, can determine suitable information embedded mode.
Also have, correcting errors in printing symbolism when handling, could imbed judging part 1402 and come computing information amount A from the amount of information that the information of imbedding of correct errors in printing symbolism processing and information embedded mode goes out to obtain to imbedding information.

Below, the computational methods that can imbed information content of image B are described.At first, under the simple situation that relies on area S, preparation in advance can be imbedded amount of information I, and the necessary correspondence table of imbedding between the area S, calculates by following formula:
Can imbed amount of information B=(blank field/area S) * I
In addition, when imbed amount of information B be dependent on plural number imbed rectangle R the time, adopts and cut-and-driedly can imbed amount of information I, and the necessary correspondence table of imbedding between the rectangle R, calculating from blank field to have several (K is individual) rectangle R.It can be calculated as follows:
When repeating same information and imbedding, amount of information B=can imbed amount of information I
When different rectangle R imbed different information, amount of information B=number K * imbed amount of information I
When blank field is not enough to obtain rectangle R, amount of information B=0
In addition, the information of imbedding is bar code, and the part of bar code is when cut, and the information of imbedding just becomes invalid.At this moment, in the time of in bar code is not included in blank field, amount of information B is 0.In the time of in bar code is included in blank field, amount of information B equals the amount of information of bar code.
Illustrate that with reference to Figure 20 the information of will imbedding is embedded to the example in the view data.Shown in Figure 20 A, amount of information is that the pattern E that imbeds of A is transfused to as imbedding information.Shown in Figure 20 B, input image data comprises blank field B1, B2 and B3.Blank field maximum among blank field B1, B2 and the B3 is as Bmax.Shown in Figure 20 C, when imbedding pattern E and be included in the blank field Bmax, the amount of information B of blank field Bmax is identical with the amount of information A that imbeds pattern E.When imbedding pattern E and be repeated to imbed, the amount of information B of blank field Bmax also equals to imbed the amount of information A of pattern E.On the other hand, when imbedding pattern E and be not included in the blank field B2, the amount of information B of blank field B2 equals 0.
Be repeated buried fashionablely with different patterns by imbedding pattern E, when amount of information A increases, just ask for big blank field Bn, imbed the number of times C that pattern E holds Bn by counting, final just can be in the hope of the information capacity A * C that can imbed.
But, correct errors in printing when correcting symbol being suitable for, because simple suitable above-mentioned Method for Area might be able to not be tried to achieve and can be imbedded information content of image, at this moment, also can adopt after imbedding information, can the detection of this information of carrying out judge according to detecting whether the information capacity that can imbed satisfies methods such as benchmark.
