Embodiment
Description will be made with reference to the accompanying drawings according to embodiments of the invention.
With reference to figure 1, image scanning system 1 comprises computer 10 and is connected to the printer 20 of computer 10 by the connection 30 such as the LAN cable.
Next, the scan process of being carried out by printer 20 will be described.
In printer 20, RAM24 preserves to be scanned and handles the value of using of setting.The value of setting is displayed on the display unit 27.With reference to the value that shows, the user can be by operating unit 21 change values of setting.The user passes through operating unit 21 input instructions with the beginning scan process.
On the other hand, in computer 10, the user activates printer driver by operating unit 11.With reference to the value of setting that shows on display unit 12, the user is identified for the value of setting of scanning process, and then input instruction is with the beginning scanning process.In response to scan instruction, the value of setting is transferred to printer 20 with scan instruction.
The value of setting that is used to scan comprises the condition of scanning, output file form, the target of output and the various types of information that are used to scan.The condition of scanning comprises resolution, tonal gradation, colouring information and other be scanned the various values that unit 29 is used to obtain view data.Such as, resolution is from 150dpi, and 200dpi chooses in these values of 300dpi and 400dpi.Further, colouring information is from comprising monochrome (2 values), and 256 grades of gray scales and each RGB have in 256 grades the color mode of polychrome and choose.
Imported from operating unit 21 or receive from computer 10 by socket 28 when scan instruction, scan process is started by CPU25 after original document is set in the scanning element 29.
With reference to figure 2, along with scan process is activated, CPU25 reads the value of setting (S101) that is transfused to be used to scan.When scan instruction by the user during from operating unit 21 input of printer 20, the value of setting is imported and is kept at the value of setting of RAM24 by the user.As selection, when scan instruction by from computer 10 transmission the time, during the value of setting from command reception to the value of setting.In this case, the condition of scanning of input comprises the resolution of input, the monochromatic or colored colouring information of the gray scale of input and input.The requirement (S102) of defined below whether the condition of scanning that CPU25 then determines to be included in the input in the value of setting that reads satisfies.In this embodiment, the condition of scanning comprises the resolution and the colouring information (tonal gradation) of input, but is not limited thereto.The condition of scanning can comprise document size.Colour can substitute 256 grades of colors and be used as colouring information.
In this embodiment, ROM23 preserves a plurality of specified conditions, promptly, preserve the polytype of particular document, the desired limited demand of each particular document, and meet limited demand and be used to scan the condition of scanning of particular document, the demand that these a plurality of specified conditions are used to a plurality of different particular document covers.Specifically, particular document comprises the document relevant with state tax revenue, and the scanning of fixed assets document and any kind needs the document of limited demand.Limited demand has limited resolution, limited tonal gradation and the limited colouring information relevant with the type of particular document.For example, as the limited demand of the document relevant with state tax revenue, ROM23 preserves 200dpi or high-resolution and 256 grades of colors or more limited demand arranged more.As the limited demand of fixed assets document, ROM23 preserves 400dpi or high-resolution and 256 grades or more limited demand arranged more.
In fact the condition of scanning is used to scan original document, and is useful on the scanning resolution of scanning original document, scanning tonal gradation and scanning colouring information.It is 300dpi that ROM23 preserves resolution, and each RGB color has the condition of scanning of 256 grades of such conditions of scanning as the state tax revenue relevant documentation.It is 400dpi that ROM23 preserves resolution, and each RGB color has the condition of scanning of 256 grades of such conditions of scanning as the fixed assets document.ROM23 further preserves and is used for determining whether original document is the condition for identification of particular document.
In step S102, determine whether the condition of scanning of input satisfies all limited demands of particular document.The limited demand that is used for particular document is read from ROM23.The resolution of input is compared with the needed ultimate resolution of minimum resolution that is used to defer to particular document.Further, the tonal gradation of input is compared with the needed maximum tonal gradation of minimal gray grade that is used to defer to particular document.Therefore, whether the resolution of making input is equal to, or greater than required limited maximum resolution, and whether the tonal gradation of input is equal to or greater than required maximum tonal gradation is determined for these two kinds.In other words, determine whether the condition of scanning of input satisfies all limited demands (S102) of particular document.
If the resolution of input is determined to be equivalent to or greater than required limited maximum resolution, the tonal gradation of input is determined to be equivalent to or greater than required maximum tonal gradation (S102: be), handles proceeding to step S103 so that scanning element 29 is not made change ground scanning original document (S103) with the condition of scanning of current input.
If the condition of scanning of input is not that all particular document are all satisfied limited demand (S102: deny), scanning element 29 scans original document to obtain original data (S104) with the preliminary sweep condition.In other words, original document is by prescan.In this case, such as, the preliminary sweep condition is typically to be used by common optical character identification (OCR), and has monochromatic mode, resolution is lower than the resolution (initial resolution) of the input of reading at S101, and tonal gradation is lower than the tonal gradation (initial tonal gradation) of the input of reading at S101.The preliminary sweep condition is stored in ROM23.Therefore, prescan is finished in the relatively short time period compared with the condition of scanning of using input.The original data that CPU25 will obtain in prescan is kept at RAM24, and carries out OCR and handle (S105) on original data.
OCR handles and carries out by original data being applied known OCR.In this was handled, original data compared with a plurality of patterns that have been stored among the ROM23.If in a part of original data matched patterns one is extracted from original data subsequently corresponding to the character or the character code of the pattern that is mated.ROM23 preserves corresponding to the keyword of each particular document and is used as whether the identification original document is the condition for identification of particular document.Particularly, one or more keywords are saved for each particular document.Such as, keyword " receipt " and " contract text " are saved for identification national tax relevant documentation.Keyword " receipt " and " budget page or leaf " are saved for identification fixed assets document.Some keywords may overlap between a plurality of different particular document.
CPU25 determines whether the character that extracts mates at least one (S106) in the keyword of discerning any particular document from OCR handles.If the character that extracts does not match any keyword (S106: not), determine that original document is not a particular document that is used to discern particular document.Scanning process proceeds to step S103 so that the condition of scanning scanning original document of scanning element 29 to import.
If any keyword (S106: be) that is used for particular document of character match that extracts determines that original document is a particular document.Then, handle and to proceed to S107 and comprise the keyword that is mated to determine whether particular document more than one.If the keyword that has only a particular document to comprise to be mated (S107: not), handle proceeding to S108.
In S108, confirm that screen is displayed on display unit 27, as shown in Figure 3.Confirm whether the screen inquiry condition of scanning that the user imported changes into the condition of scanning of the particular document of discerning in S107.By confirming the mode of screen, the user is by one in operating unit 21 selections " acceptance " and " cancellation ".If the user selects " cancellation " (S109: be), scan process proceeds to S103.Scanning element 29 is not done the scanning original document of change with the condition of scanning of current input.
On the other hand, if the user selects " acceptance " (S109: not), handle and proceed to S110, and the condition of scanning is changed the condition of scanning for the particular document of discerning in S107.In S110, scanning element 29 is to be used for the condition of scanning scanning original document (S110) of particular document.
As for S108, if scan instruction is imported from computer 10, confirm that screen is displayed on the display unit 12 of computer 10, rather than printer 20.
If a plurality of particular document have the keyword (S107: be) of coupling, handle proceeding to S111.In S111, select screen to be displayed on display unit 27, as shown in Figure 4.Select several possible types of screen display particular document.Selection screen request user selects a kind of (S111) in the particular document type.Selecting on the screen, the possible type with particular document of coupling keyword is enumerated out.The user utilizes operating unit 21 to select a class particular document from tabulation.If selecting to select " cancellation " (S112: be) on the screen, handle proceeding to S103, scanning element is with the condition of scanning scanning original document of input.On the other hand, if " reception " selected (S112: deny), the condition of scanning of input is changed the condition of scanning into selected particular document.Processing proceeds to S113, and scanning element 29 is to be used for the reformed condition of scanning scanning original document (S113) of selecteed particular document.
About S111, if scan instruction is imported from computer 10, select screen to be displayed on the display unit 12 of computer 10, rather than printer 20.
In S111, if the keyword that has a plurality of particular document to have coupling, the possible type of particular document can be shown by the order of number with the coupling keyword.Can be alternatively, the particular document with coupling keyword of maximum quantity may automatically be selected.
At S103, S111, or the view data that obtains among the S113 is transferred to the export target such as the such value of the setting appointment of computer 10.
As described previously, according to this embodiment, if original document is confirmed as particular document, original document is scanned with the condition of scanning that is suitable for particular document.Therefore, even original document is a particular document, such particular document can be scanned with the suitable condition of scanning.
Further, when particular document will be scanned, and the condition of scanning of input is not when meeting the desired limited demand of particular document, and particular document is by the condition of scanning scanning with the limited demand that meets particular document.Therefore, the mistake setting that is used for the condition of scanning of original document can be reduced.
If the condition of scanning of input satisfies the limited demand that is used for particular document, original document is by the condition of scanning scanning with input.In this case, CPU25 confirms that whether original document is that the affirmation of particular document is handled (S104 is to S106) and can be omitted.Therefore, scan process was finished in the short time period.
The limited demand that is used for particular document needs chromoscan when having.In this case, chromoscan is performed, even when the condition of scanning of input comprises monochromatic mode.This needing can be avoided the original document of chromoscan to be scanned by monochrome mistakenly.
Further, if original document is confirmed as particular document, the user whether can select that the condition of scanning should be changed (S108, S109).Original document can be scanned according to the condition of scanning of customer requirements.
Further, if original document has a plurality of possible particular document, the user can select in a plurality of conditions of scanning one (S111, S112).Original document can be scanned according to the condition of scanning of customer requirements.
Further, based on the character that from the raw image data that produces by prescan (S106), extracts, determine whether original document is particular document.Original document can be scanned with the condition of scanning according to customer requirements.Further, can determine more accurately whether original document is particular document.
Whether original document is that the judgement of particular document is to obtain on the basis of the view data of the prescan that uses the preliminary sweep condition, and the preliminary sweep condition is used to all prescans.The preliminary sweep condition is set to have monochromatic mode, is lower than the resolution of input and the resolution and the tonal gradation of tonal gradation.Therefore, identical preliminary sweep condition is used to each prescan, makes that original document is accurately determined.Further, the time of implementation of prescan is shorter than the time that the condition of scanning scanned by input.
Then, the second embodiment of the present invention will be described with reference to figure 5.In this embodiment, ROM23 preserves the information of " resume " (curriculum vitae) as particular document.ROM23 further preserves the desired limited demand of resume (resolution, tonal gradation and colouring information) and the condition of scanning that conforms to it.The limited demand of resume comprises 300dpi or higher resolution and 256 grades of colors or more tonal gradation.The condition of scanning of resume comprises resolution and 256 grades of colors or the more tonal gradation of 600dpi.
Along with scan process is activated, CPU25 reads value of setting (S201) that being used to of being set up scan.CPU25 determines then whether the condition of scanning that is included in the value of setting of input satisfies limited demand (S202).
What in this embodiment, CPU25 need do is to determine whether the condition of scanning of input satisfies the condition of scanning of resume.The limited demand that it should be noted that resume is required to define the condition of scanning of resume.
If the condition of scanning of input satisfies limited demand (S202: be), original document is used the condition of scanning scanning of input.On the other hand, (S202: not), original document is by prescan (S204) if the condition of scanning of input does not satisfy limited demand.In this case, the resolution that prescan is performed is lower than the resolution of the condition of scanning of input, and this resolution generally can be used for typical OCR to be handled, and the tonal gradation of RGB color is lower than the tonal gradation of the condition of scanning of input.The resolution and the tonal gradation that are used for prescan are stored in ROM23.
Then, by the raw image data that prescan produced analyzed (S205), CPU25 determines whether raw image data comprises natural image (nature image) (S206).Specifically, such as, the distribution of color of raw image data (every kind of pixel number of color) is analyzed.If the variation of distribution of color is slower than reference point, think that original image comprises natural image.If determine that based on analyzing view data does not comprise natural image (S206: not), determine that original document is not " resume ".In this case, handle proceeding to S203, original document is used the condition of scanning scanning (S203) of input.On the other hand, if determine that raw image data comprises natural image (S206: be), this result means that original document is resume.In this case, process proceeds to S207.And the condition of scanning that is used for resume that the condition of scanning of input is read from ROM23 substitutes.Original document is used for the condition of scanning scanning (S207) of resume.
According to this embodiment, if comprise the original document as the photo of natural image like this such as resume, license, different application form, the condition of scanning that meets the limited demand of the particular document that is used to comprise photo is used to scan original document.This has been avoided the photo in the original document by mistakenly with lower resolution scan.
Further, the analysis to the distribution of color of raw image data makes about raw image data whether comprise determining of natural image.Therefore, whether comprise determining and to be made accurately of natural image about raw image data.
In image analysis process, whether be the factor of particular document as definite original document, CPU25 can determine the size of original document.Can be alternatively, CPU25 can determine size or the position of natural image in original document.
Next, the third embodiment of the present invention will be described with reference to figure 6.In this embodiment, ROM23 preserves " document text " (address book) as particular document.ROM23 further preserves the desired limited demand of document text and is used for the condition of scanning of scanned document text.The limited demand of document text requires monochromatic scanning.The condition of scanning of document text comprises the resolution of 300dpi.
Along with scan process is activated, CPU25 is with initial condition of scanning prescan original document, to produce raw image data (S301).In this case, the preliminary sweep condition comprises monochromatic mode and is used for determining whether raw image data comprises the desired lowest resolution of natural image.The used preliminary sweep condition of prescan is stored among the ROM23.The initial resolution of preliminary sweep condition is lower than the resolution of the condition of scanning that is used for the document text, and the size that has been stored in ROM23 is the resolution of 300dpi.
Next, CPU25 analyzes raw image data (S302), and whether definite raw image data only is made up of character.Specifically, such as, the distribution of color of raw image data is analyzed, if the distribution of color of raw image data has such part, in this part, the variation of distribution of color is slower than reference point, and this feature means that raw image data may comprise natural image.Therefore, CPU25 determines that raw image data not only is made up of character.Otherwise CPU25 determines that raw image data only is made up of character.
If the analysis result display image data is not only to form (S303: deny) by character, CPU25 determines that original document is not the document text.Processing proceeds to S304, and wherein original document is scanned with the preliminary sweep condition.On the other hand, CPU determines that view data only forms (S303: be) by character, and this result means that original document is the document text.Processing proceeds to 305.In S305, OCR handles and carries out on raw image data.In OCR handled, raw image data was compared with the pattern that is kept among the ROM23.Corresponding, the characters matched (keyword) that is comprised in the raw image data is extracted.
Next, CPU25 determines whether character extracts (S306) by the mode of using OCR to handle from original document.If character is extracted (S306: be), scan process is terminated.Specifically, the raw image data that is produced by prescan is transferred to the export target such as computer 10.On the other hand, if character is not extracted (S306: not), handle proceeding to S307.In S307, the condition of scanning that is used for the document text is read from ROM23, and original document is scanned with resolution and the monochromatic mode that is higher than original resolution.(S307)。
In this embodiment, if the character in the raw image data can not be identified, scanning is carried out with the resolution that is higher than original resolution.Therefore, if original document is the document text, this is handled and guarantee to extract character at an easy rate from view data.
Further, if prescan is to carry out with the condition of scanning that is different from the preliminary sweep condition, and the character in the view data is identified, and scanning process is terminated and does not further scan.This step reduces the quantity of the scanning that will be performed.
Still in this embodiment, the color mode that promptly is used in scanning is set up, and original document is scanned with monochromatic mode.This step reduces the size of the view data that obtained by scanning.
In the above embodiments, mark and figure and character can be extracted in view data.If mark or figure are not extracted by prescan, original document can scan with the resolution that is higher than the initial resolution that prescan adopted.
Further, if character is not extracted by the scanning of high-resolution, scanning can repeat with higher resolution.Therefore, if view data comprises in character, mark and the figure at least one, character, mark and figure can be scanned processing and accurately extract.
Next, the fourth embodiment of the present invention will be described with reference to figure 7.In this embodiment, ROM23 preserves a plurality of bar code type such as " code 39 ", " JAN13 " or " POSTNET ".Each bar code is specified corresponding particular document.ROM23 further preserve with corresponding to the relevant information of the data format of all kinds of bar codes.ROM23 preserves the condition of scanning that meets the limited demand that is used for each bar code document.
When scan process is activated, CPU25 with preliminary sweep condition prescan original document to produce raw image data (S401).In this case, the preliminary sweep condition comprises monochromatic mode and is used for determining whether the bar code of view data indicates the needed minimum resolution of particular document.The preliminary sweep condition is stored among the ROM23.Next, CPU25 analyzes raw image data (S402) and determines whether that subsequently bar code is comprised in (S403) in the raw image data.If (S403: not), CPU25 determines that original document is not by the specified particular document of bar code not have bar code in the view data.Processing proceeds to S304.In S304, original document is scanned (S404) with the condition of scanning via operating unit 21 or computer 10 inputs.
Further, if raw image data has bar code (S403: be), CPU25 determines whether that the bar code in the initial data comprises the data (S405) that indicate particular document.If being determined, the bar code in the raw image data do not comprise the data (S405: not), can determine that original document is not the particular document by the bar code appointment that indicates particular document.Processing proceeds to S404, and original document is by the condition of scanning scanning with input.
On the other hand, if the bar code in the raw image data comprises the data (S405: be) that indicate particular document, this means that original document is the specified particular document of bar code in the raw image data.In this case, processing proceeds to S406.In S406, the condition of scanning relevant with the specified particular document of bar code read from ROM23.Original document is scanned (S406) with this condition of scanning.
Next, the fifth embodiment of the present invention will be described with reference to figure 8.In this embodiment, scanning element 29 is scanners of mode transmission.The document that the ROM23 preservation has watermark is as particular document, and specific watermark recovery is corresponding to the document with watermark.ROM23 further preserves the condition of scanning of the limited demand that meets the document that watermark recovery is arranged.
When scan process was activated, CPU25 scanned original document to obtain raw image data (S501) with the preliminary sweep condition.In this case, the preliminary sweep condition has monochromatic mode and is used for determining whether view data comprises the desired minimum resolution of specific watermark recovery.The preliminary sweep condition is stored among the ROM23.Next, CPU25 analyzes raw image data (S502), and determines whether that view data comprises specific watermark recovery (S503).(S503: not), CPU25 determines that original document is not the particular document that watermark recovery is arranged if view data does not comprise specific watermark recovery.Therefore, processing proceeds to S504.In S504, original document is scanned with the condition of scanning in the set input of processing beginning.
In S503, be included in the raw image data watermark recovery by be kept among the ROM23 watermark recovery and make comparisons.If the watermark recovery in the raw image data is complementary with one that is kept in the watermark recovery among the ROM23, CPU25 determines that raw image data comprises specific watermark recovery.
On the other hand, if raw image data comprises one (S503: be) in the specific watermark recovery, CPU25 determines that original document is the particular document with watermark.Processing proceeds to S505.In S505, the condition of scanning relevant with the particular document that watermark is arranged read from ROM23.Then, original document is scanned to produce view data (S505) with this condition of scanning.
Next, the sixth embodiment of the present invention will be described with reference to figure 9.In this embodiment, tape (magnetictype) formula scanner is used to determine whether original document is particular document.The magnetic tape type scanner, such as, can be set at by the head of scanning element 29.
The operation of the head of magnetic tape type scanner scanning original document and scanning head 29 is synchronous, and to read the magnetic that is included in the magnetic material in the recording materials that comprise toner and ink, these recording materials are used to recorded information on original document.Therefore, can generate and indicate the view data that is included in by the distribution of the magnetic material in the original document of the magnetic scanning of magnetic scanning instrument (after this being called the magnetic cartographic information).ROM23 preserves the magnetic cartographic information relevant with particular document, and the condition of scanning that meets the limited demand of particular document.
When scan process was activated, CPU25 magnetically scanned original document to generate magnetic cartographic information (S701) with the preliminary sweep condition.CPU25 then compares magnetic cartographic information and the magnetic cartographic information (S702) that is used for particular document.If the magnetic cartographic information does not match the magnetic cartographic information (S702: deny) of arbitrary particular document, CPU25 determines that original document is not a particular document.Processing subsequent proceeds to S703.In S703, original document is by the condition of scanning scanning with the input of setting in the processing beginning.
On the other hand, if the magnetic map information matches that is scanned is used for one the magnetic cartographic information (S702: be) of particular document, CPU25 determines that original document is a particular document.Processing subsequent proceeds to S704.In S704, the condition of scanning of particular document is read from ROM23.And original document is scanned (S704) with this condition of scanning scanning rather than with the condition of scanning of importing.
As described previously, original document can be scanned with the suitable condition of scanning according to the definite type of particular document, to generate view data.Depend on the application of view data, view data can be stored in RAM24 or be transferred to computer 10.
The present invention is not restricted to top embodiment and appended picture.Such as, following change is exactly within the scope of the present invention.
