MFP11 provides multiple function, as facsimile function, scanner functions, printer function and copy function.MFP11 comprises operation display unit 26, and it is provided at the last front side of MFP11 main body, and this operation display unit 26 comprises the enter key that is used for input transfer destination title, transmits the destination fax number and transmit the destination addresses of items of mail.And operation display unit 26 comprises switching push button and start button and the stop button that is used to switch such as the pattern of fax pattern and printer mode.Particularly, in the present embodiment, operation display unit 26 is provided with the important key (significant key) that is used for input identifier (special keyword), and this identifier is used to reduce following the reducing of image size to be handled.
In the printer function of MFP11, when control unit 21 by network receive from client PC 12 have the print command of print data the time, generate view data according to print data, and pass through print unit 24, on paper, carry out printing according to this print data.In scanner functions, be placed on file on the file load unit by scanning element 25 scanning, and represent the view data of the scan image of this document to be generated and to be stored in the premise equipment on the network.
In the copy function of MFP11, scan the file that is placed on the file load unit by scanning element 25, and represent the view data of the scan image of this document to be generated.Then, the image based on this view data is printed on the paper by print unit 24.In addition, in facsimile function, when the time by operation display unit 26 input facisimile transmission orders, by scanning element 25 scanning documents, and the scan image based on this document generates facsimile data, and then via the public telephone spider lines, 27 transmit facsimile data from the line traffic unit.Simultaneously, when via line traffic unit 27 when outside facsimile machine is received faxes data, the facsimile data that is received is converted into view data, and this view data is printed on the paper by print unit 24.
MFP11 is provided with document generator, and it is used for being created on the image data file that every feature operation generated of MFP11, and the file that is generated is stored in the precalculated position of history management server 13.Simultaneously, history management server 13 comprises the history management program that is stored in wherein, be used for carrying out according to pre-defined rule and reduce to handle, in this pre-defined rule, the storage cycle that is sent view data by MFP11 is stored explicitly with the ratio that reduces that is used to reduce the view data size.
The history management program of history management server 13 is configured to basis setting as shown in Figure 3, promptly according to the cycle is set, changes the compression ratio of view data stage by stage, thus the size of the view data that reduces to store.Particularly, according to the history management program, pass by 60 days (2 months), 365 days (1 year) or 1825 days (5 years) afterwards from oneself is stored in view data, the compression ratio of view data is changed into 80%, 30% or 0% (deletion) respectively stage by stage.It should be noted that the history management program is made identifier (special keyword) import arbitrarily according to the cycle is set by configuration like this.Particularly, in following step S115, when view data is converted into filename when comprising the file of character string (special keyword) " important ", even a certain that the cycle is set is over and done with, the compression of view data also can be under an embargo.
For example, only suppose at cycle that is provided with of 365 days and input identifier " important ".In this case, when the view data storage cycle past tense of 60 days (2 months), view data can be compressed with 80% compression ratio.Yet, the storage cycle past tense when 365 days (1 year), because identifier " important ", view data is compressed and can be under an embargo with 30% compression ratio.Correspondingly, in the cycle in 5 years after 60 days cycle, this view data is preserved with the compressed state of 80% compression ratio always.Then, after the period expires in 5 years, this view data is deleted.
And, when at cycle that is provided with of 1825 days and during input identifier " important ", this view data is forever preserved.In this case, when at any other cycle input identifier " important " not being set, this view data is forever preserved after compressing with compression ratio 80% or compression ratio 30%.For example, unless at 60 days the cycle that is provided with input identifier " important ", this view data is with 80% compression ratio compression.In addition, unless at 365 days the cycle that is provided with input identifier " important ", this view data is permanently stored in the state with 30% compression ratio compression.It should be noted that this view data is forever preserved, and is not compressed when cycle input identifier " important " is set at all.
In addition, MFP11 is configured to not only by the important key based on the operation display unit 26 of user view, and by automated manner, converts view data to file (referring to S115) that filename comprises identifier " important ".Particularly, for example, concrete character " only uses " presumptive area that is stored in storage element 22 as keyword for inner.Then, when control unit 21 by the character analysis, determine whether to be included in the view data that scanning element 25 scanned with the corresponding character of keyword.When determining to be included in the view data with the corresponding character of keyword, this view data is automatically converted into the file (referring to S115) that filename comprises identifier " important ".
And MFP11 is configured to by LAN cable 10, and the data with in the predetermined storage facilities (predetermined file folder) that is stored on the network convert the file (referring to S115) that filename comprises identifier " important " automatically to.That is, storage element 22 will be scheduled to storage location and save as keyword in its presumptive area.When control unit 21 is determined, for example, when being stored in data consistent in the predetermined storage location as keyword in data of printing and the storage element 22, the data that print are automatically converted into the file (referring to S115) that filename comprises identifier " important ".And distinguished symbol is stored in the presumptive area of storage element 22 as keyword.Whether the filename of the control unit 21 definite data that will print comprises this distinguished symbol.When the filename of the data of determining to print comprised this distinguished symbol, these data were automatically converted into the file (referring to S115) that filename comprises identifier " important ".It should be noted that the data that will print comprise storage location and the filename as its related information.
To describe below by MFP11 execute file generator.Fig. 4 shows the flow chart that MFP11 is stored into file by document generator the process of history management server 13.
As mentioned above, MFP11 carries out each function operations such as copy function.Control unit 21 is monitored this operation always.Particularly, control unit 21 is monitored copying operation always and whether is performed (S101), facisimile transmission and whether is performed (S102), facsimile data and whether is received (S103), printing and whether is performed (S104) and scan operation and whether is performed in (S105) each.In these operations any one is unrecognized, and (S101-S105: not), above-mentioned monitoring just is repeated to carry out.
Simultaneously, any one in the aforesaid operations is identified, and MFP11 is by access to netwoks history management server 13.Particularly, in the MFP11 access file folder predetermined one, described file is used as the view data storage location in the storage element 35 of history management server 13 and provides.
Fig. 5 shows the schematic diagram of view data storage location in the storage element 35 that is provided at history management server 13.Therefore, storage element 35 be provided with MFP11 each the operation corresponding each file name file.Particularly, storage element 35 comprises hard-copy file folder 121, to store the image that duplicates therein; Facisimile transmission file 122 and fax receive file 123, and it is produced and is used for storing therein facsimile signal; Mimeograph documents folder 124 is with storage print image therein; And scanning document folder 125, to store scan image therein.
When carrying out copying operation (S101: be), the hard-copy file of MFP11 access history management server 13 folder 121 (S106).When not carrying out copying operation (S102: be) when carrying out facisimile transmission, the facisimile transmission file 122 (S107) of MFP11 access history management server 13.When not carrying out facisimile transmission (S103: be) when receiving faxes data, the hard-copy file of MFP11 access history management server 13 folder 123 (S108).When not receiving any facsimile data (S104: be) when carrying out printing, the mimeograph documents of MFP11 access history management server 13 folder 124 (S109).When not carrying out printing (S104: be) when carrying out scan operation, the scanning document of MFP11 access history management server 13 folder 125 (S109).
Simultaneously, in history management server 13, as shown in Figure 5, each that is provided in each file (operation file folder) 121 to 125 of operation includes moon file 211,212,213 ... each described file all generates with lower-level in every month automatically.Correspondingly, for example, the MFP11 visit is provided at the moon file 211 (S111) under operation file folder 121 to 125 each file.Every month, file was given the folder name by 6 bit digital representatives of time and month combination.For example, the moon file 213 that generates in August, 2007 has folder name " 200708 ".Correspondingly, when when carry out copying operation in August, 2007, MFP11 visit month file 213.
Subsequently, the MFP11 view data that will be used as target data in copying operation or fax operation converts the subsidiary file that filename is arranged to.At this moment, the execution of the conversion from the view data to the file is had ready conditions or is not had any condition.Therefore, MFP11 checks in every operation whether given and any condition (S112 and S113).Particularly, in S112, check whether the important key of operation display unit 26 is pressed in the operation such as copying operation or facisimile transmission.Simultaneously, when by the facisimile transmission file, even important key is not pressed, in S113, control unit 21 determines whether be included in the view data that is scanned with the corresponding character of keyword that is stored in the storage element 22 by the character analysis.
Then, in the step that view data is converted to file after that (S114 or S115), the name of the function that MFP11 is performed and be added in the name of this document at the 3 bit digital sequence numbers of each function in this middle of the month.For example, when important key in copying operation is not pressed (S112: not), and be stored in the unrecognized (S113: in the time of not), give the filename shown in file among Fig. 5 311 or 313 (S114) of any keyword in the storage element 22.That is, file 311 or 313 filename comprise character " Cpy ", and copy function is carried out in its expression, and sequence number " 001 " or " 003 " are represented first or the 3rd in the performed copying operation of in August, 2007 respectively.
Simultaneously, when important key is pressed in copying operation (S112: be) or be stored in keyword in the storage element 22 in the view data of scanning when being identified (S113: be), shown in file among Fig. 5 312, character " important " is added in the filename of file 312 (S115).Therefore, this document name comprises character " important ", is added on expression and carries out the character " Cpy " of copy function and represent in the performed copying operation of in August, 2007 between second the sequence number " 002 ".It should be noted that the filename that is given can be included in the filename (primitive name hereinafter referred to as) that is used as the view data of target data in this operation in S114 or S115.In this case, the filename tabulation that is used for management document of deleting in following step S207 according to the primitive name of deleted file, specifies in and comprises in the deleted file which kind of information is possible.
Next, in the present embodiment, the file that view data converted in S114 or S115 is compressed into the zip form.As shown in Figure 5, compressed file is stored into the predetermined file folder (S116) of history management server 13.In above-mentioned example, compressed file is stored in the file 213 that generates in August, 2007, and this document double-layered quilt is provided under the hard-copy file folder 121.It should be noted that the file that view data converts to can be stored in the predetermined file folder of history management server 13 under unpressed situation.And this document can compress with the different-format except that the zip form.
Therefore, MFP11 will have the view data of the file of predetermined file name to be sent to history management server 13 as subsidiary, be stored into the predetermined file folder of storage element 35 subsequently.On the other hand, in history management server 13, be stored in view data wherein, according to the passing of time, compress, to reduce the capacity of view data by stages according to predetermined compression ratio.This squeeze operation is carried out by control unit 31, more particularly, utilizes and carries out the image history hypervisor execution that history management is handled, as shown in Figure 6.For example, the history management server is carried out a history management 13 every days and is handled, and is stored in wherein image with management.
In history management is handled, at first, comprise that the filename and the managing listings information of date of formation (referring to compressed list among Fig. 7 40) of the view data of all storages is proposed (S201) from storage element 35.Then, according to the date of formation and the current date of the file of each view data, for the image information of each storage is determined storage cycle (S202) in the current time.Storage cycle by each file relatively and cycle is set determines whether that documentary storage cycle surpasses any cycle (S203) that is provided with.When the storage cycle that does not have file surpasses any cycle (S203: in the time of not), determine that All Files is examined, and history management is handled termination that is provided with.
Simultaneously, when existing storage cycle to surpass any file (S203: be) that the cycle is set, determine whether this view data compresses (S204) with certain compression.History management server 13 is included in the compressed list 40 that wherein generates, as shown in Figure 7.Pass by and squeeze operation when being performed when the cycle that is provided with, this operation is recorded in the compressed list 40 extraly.Therefore, by calling compressed list 40, the compressive state of confirming each view data is possible.When the view data of determining to be included in according to compressed list 40 in the file destination has been compressed (S204: be),, in this step, determine whether that another storage cycle surpasses any file that the cycle is set when S203 is returned in pre-treatment.
Simultaneously, when determining that according to compressed list 40 view data of file destinations is not compressed (S204: in the time of not), determine whether comprise identifier (S205) in the filename of file destination.Be saved in view data under the situation of the file that comprises identifier " important " for filename, shown in file among Fig. 5 312, determine in S205 whether the filename of this file destination comprises identifier " important ".When this document name comprises identifier " important " (S205: be), when S203 is returned in pre-treatment.In the present embodiment, this among the S205 determined to come from identifier " important " and at all is set the cycle and all is provided with, as shown in Figure 3.Simultaneously, and when filename does not comprise identifier " important " (S205: not), when pre-treatment is advanced into S206.In S206, determine whether to delete this file destination.Particularly, in the present embodiment, judge that in S206 whether the cycle of determining that is provided be applied among the S203 is 1825 days the cycle that is provided with (that is, whether the storage cycle of file destination has surpassed 1825 days the cycle that is provided with).As definite file destination (S206: be) when deleted, when pre-treatment is advanced into S207.Simultaneously, and when definite this file destination will not deleted (S206: not), when pre-treatment is advanced into S210.
In S207, for the deleted image data, its corresponding file is deleted.And, determine in month file at this document place, whether have any file (S208).When deleted and this month, file was for empty (S208: be) when All Files, blank month file also deleted (S209).
In storage element 35, be provided at the filename tabulation of the filename of wherein having preserved the file of deleting with aforementioned manner.Deleted in S207 when view data, the filename of this view data is added into this tabulation.Simultaneously, stay (S208: not),, in this step, determine whether to exist storage cycle to surpass any file that the cycle is set in moon file as file when S203 is returned in pre-treatment.
In addition, in S210, view data is to compress corresponding to the compression ratio that the cycle is set, and the described cycle quilt storage cycle of determined view data in S203 that is provided with surpasses.Particularly, when the storage cycle of view data surpassed 60 days (2 months), this view data was compressed with compression ratio 80%.When the storage cycle of view data surpassed 365 days (1 year), this view data was compressed with 30% compression ratio.Fig. 8 shows the flow chart of the process of compressing image data in S210.
As mentioned above, view data is as being stored in the history management server 13 with the file of zip form compression by MFP11.In order to compress this view data, at first launch the zip file and from extraction image bitmap data (S301) wherein.With 60 days corresponding squeeze operation of the cycle that is provided with in, 100% view data is compressed with compression ratio 80%.In the squeeze operation corresponding with 365 days the cycle that is provided with, the view data of having been carried out compression with 80% compression ratio is compressed, to obtain 30% compression ratio (S302).Therefore, the view data of as above compressing saves as the recompression file (S303) of zip form in the original document folder with coverage mode.
When carrying out squeeze operation at single view data each time, the information of relevant this view data is registered in as shown in Figure 7 the compressed list 40 (S211).In compressed list 40, filename, the file date of formation in MFP11 and be transfused to as the compression ratio of the compression of the current execution of up-to-date compression ratio.It should be noted that, as the 3rd file " copy003 " that generates by copying operation in the same middle of the month, represent that at the filename shown in compressed list 40 tops corresponding view data is stored in the moon file " 200510 " that generates in October, 2005, under the hard-copy file folder " Copy " of described file in driver C.
With reference to figure 6, after view data is carried out squeeze operation,, in this step, determine whether to exist storage cycle to surpass any file that the cycle is set when pre-treatment is back to S203.Do not comprise identifier for its filename, and its storage cycle surpasses any file that the cycle is set, step S204 to S211 carries out in the same manner as described above.After this, (S203: not), history management is handled and is terminated when not existing storage cycle to surpass any file that the cycle is set.Above the description of relevant Fig. 6 be based on Fig. 3, wherein, identifier " important " is provided with the cycle at all and is provided with.Yet identifier " important " can only be provided with at the predetermined set cycle.For example, identifier " important " can be not be provided with at cycle that is provided with of 60 days.In this case, carry out among the follow-up S205 that fixes on Fig. 6 really.For example, the filename that comprises " important " when file destination has, its storage cycle surpasses 60 days the cycle that is provided with, and in S204, carry out determining of negating, because identifier " important " is not provided with at cycle that is provided with of 60 days, even this document name comprises " important ", also in S205, carry out (the S205: not) that determines that negates.Then, when pre-treatment is advanced into S206, and be performed with top described identical step subsequently.
According to present embodiment, by preserving view data that duplicate or fax, it is possible utilizing this view data when needed.For example, when the user attempt to confirm this pictorial data representation what or when faxing this view data once more, this view data can be used.Yet in most cases, the value of utility of this information (frequency that reuses) is passed in time and is descended.Therefore, in the present embodiment, the compression ratio of passing the view data of value of utility decline is in time reduced interimly, to reduce the capacity of view data.Thereby, can solve the deficiency of the storage volume of history management server 13.On the other hand, in order to duplicate the important view data that is in the rapid wear state,, restriction is made in the compression of view data according to the importance of view data.And when keeping during important view data, view data is so stored, so that be included in the compression that identifier in the image data file name comes the limited images data by automatic identification.Therefore, can keep view data, for example, use the evidence of this view data as unauthorized.
Embodiment has according to certain aspects of the invention above been described.The present invention can realize by adopting traditional material, method and device.Correspondingly, the details of this material, device and method does not elaborate at this.In the description in front, in order to provide, many details have been set forth, as concrete material, structure, chemicals, processing etc. to thorough of the present invention.Yet, should be noted in the discussion above that the present invention can realize under the situation of not redistributing these concrete details of setting forth.In other examples,, the known processing structure of crowd is not described specifically for fear of unnecessarily fuzzy the present invention.
In the disclosure, only illustrate and described one exemplary embodiment of the present invention and several multi-functional example of the present invention.It should be noted that the present invention can be used in various other combinations and environment, and in the inventive concept scope that can be set forth herein, make a change or revise.For example, according to certain aspects of the invention, following change and modification are possible.
In the aforementioned embodiment, history management server 13 is as management server.Yet for example, the MFP11 that is connected with external storage device 28 as shown in Figure 9 can be used as management server.In this case, the moon file 211,212 and 213 shown in Fig. 5 generates in storage facilities 28.Then, view data as the file that generates, is stored into moon file 211,212 and 213 according to above-mentioned process shown in Figure 4.And in this case, MFP11 comprises the image history hypervisor that is stored in its storage element 11, and the history management of carrying out is as shown in Figure 6 handled.Therefore, also be in this case, be kept in the storage facilities 28 by the view data that will duplicate or fax, it is possible using this view data when needed.In addition, because the compression ratio of view data is reduced interimly,, can provide the effect identical in this case with previous embodiment to reduce the capacity of view data.That is, can solve the deficiency of the capacity of storage facilities 28.
In addition, in the previous embodiment, view data is converted into the file that filename comprises identifier, and this identifier provides restriction in the Image Data Compression process.Selectively, can generate the tabulation that has on it as the given mark of identifier.For example, when view data was stored in the predetermined file folder of history management server 13 as shown in Figure 5, compressed list as shown in Figure 7 can be generated and be stored in the storage element 35.Compressed list can comprise mark part, and wherein, that the cycle is set is given according to shown in Figure 3 for mark.Correspondingly, in history management shown in Figure 6 was handled, the state of the mark part by checking destination image data determined whether the compression goal view data.In a word, when predefined identifier was associated with destination image data, the size of destination image data may be reduced in restricted mode.
In addition, in the aforementioned embodiment, when the compression ratio phasic Chang of view data, with the example of zip form as the compressed format that is used for the file that compressing image data converts to.Yet compressed format can comprise extended formatting, as nondestructive compression type, wherein, view data is carried out squeeze operation or launch operation before and afterwards, the picture quality no change, and after launching operation, the original image of view data can be recovered fully; And the lossy compression method form, wherein, can obtain lower compression ratio (compress more images data), yet after launching operation, the original image of view data can not be recovered fully.For example, jpeg format can be used as the lossy compression method form, and the GIF form can be used as nondestructive compression type.
In order to reduce the view data size, can carry out pixel to view data and jump over squeeze operation described in (skipping) operation and the previous embodiment.For example, in the pixel operation loop, on each vertical and horizontal direction of view data, delete pixel data, to generate new view data every the number row.It should be noted that preferably, after the pixel operation loop, can carry out the interpolation operation.And, can be by number of greyscale levels (that is tone level) that reduces view data or the size that number of colors reduces view data.For example, the number of the number of greyscale levels of view data can be decreased to 256 shade of gray from 1024 shade of gray stage by stage according to the predetermined cycle that is provided with.And the number of colors of view data can be decreased to monochrome image from coloured image stage by stage according to the predetermined cycle that is provided with.In addition, can reduce the size of view data by the combination of various operations.For example, when the storage cycle of view data relatively more in short-term, can carry out squeeze operation to this view data.Simultaneously, when the storage cycle of view data is longer relatively, can carry out the pixel operation loop, reduce the number of grayscale levels operation or reduce the number of colors operation this view data.It should be noted that " size " of view data refers to the size of data of this view data, that is, and the data capacity of this view data.
And in the superincumbent description, history management server 13 or the storage facilities 28 that is connected with MFP11 can be provided as the storage location of store images data.Yet the client PC 12 on the network also can be designated as storage location.In addition, be provided with cycle, compression ratio or stage by stage the number of steps of compressing image data can be provided with arbitrarily.
In addition, " important _ a ", " important _ b ", " important _ c " can be set to identifier as shown in figure 10.This set can provide multiple variation for determining among the S113.For example, suppose that specific character " only uses for company ", " only using for department " and " secret " is used as keyword and is stored in the presumptive area of storage element 22.In this case, when being identified in S113, destination image data can be converted into the file that filename comprises " important _ a " when " only using for company ".Simultaneously, when being identified in S113, view data can be converted into the file that filename comprises " important _ b " when " only using for department ".And when " secret " was identified in S113, view data can be converted into the file that filename comprises " important _ c ".Thereby according to the type of the keyword of being discerned, the setting that changes squeeze operation is possible.
And, for example, suppose that predetermined storage location x, y and z are stored in the presumptive area of storage element 22 as keyword.In this case, when storage location x was identified in S113, this view data can be converted into the file that filename comprises " important _ a ".Simultaneously, when storage location y was identified in S113, this view data can be converted into the file that filename comprises " important _ b ".And when storage location z was identified in S113, this view data can be converted into the file that filename comprises " important _ c ".Thereby according to the type of the keyword of being discerned, the setting that changes squeeze operation is possible.
When distinguished symbol x, y and z are stored in the presumptive area of storage element 22 as keyword, for example, under the situation that distinguished symbol x is identified in S113, this view data can be converted into the file that filename comprises " important _ a " in the same manner as described above.It should be noted that, in S205, can determine and corresponding identifier of cycle (" important _ a ", " important _ b " or " important _ c ") is set whether is included in the filename of file destination, describedly the cycle is set is confirmed as being surpassed by the storage cycle of file destination.
In addition, when " important _ a ", " important _ b " and " important _ c " are set to identifier as shown in figure 10, may the cycle be set two or more identifiers are set at single.Particularly, for example, " important _ a " and " important _ b " may be set to the identifier for cycle that is provided with of 60 days.This set can provide more variation for determining among the S113.
