In order to further describe above-mentioned one embodiment of the present invention, image processing apparatus and the image processing method of one embodiment of the invention is described referring to figs. 1 through Figure 13.Fig. 1 means the figure of surface structure of the image processing apparatus of the present embodiment, and Fig. 2 means the block diagram of the structure of image processing apparatus.In addition, Fig. 3 is the image graph that schematically shows output image reading part, Fig. 4 and Fig. 5 be explanation for measuring the figure of mechanism of the concentration of the spot in transfer belt, Fig. 6 means the flow chart of action of the image processing apparatus of the present embodiment.In addition, Fig. 7 means the figure of an example of testing of printed, and Fig. 8 is the figure that explanation is the method for two points by a point transformation, and Fig. 9 is for the image graph of the method that changes the beam diameter that writes laser is described.In addition, Figure 10 is transformed to the table of regarding the cumulative time as by accumulative total service time, and Figure 11 and Figure 12 are that Figure 13 means the table of the determination data of sample by the table of use of paper message and device information and printing morphologic correlation connection.
As shown in Figure 1 and Figure 2, the image processing apparatus 100 of the present embodiment is the device that possesses the printing functionality of printer and compounding machine etc., by formations such as control part 10, output image reading part 20, ADF (automatic paper feeder) 30, IDC (image density control) sensor 40, temperature sensor 50, operation inputting part 60, image printing portion 70, collector lens adjustment part 80, display parts 90.
Control part 10 is parts of controlling each formation portion, and CPU (CPU) 11, communication I/F portion 12, HDD (hard disk drive) 13, RIP (raster image processor) video memory 14, output image read memory 15, use of paper message are held memory 16, execution use memory 17 etc. and connected via bus.
CPU11 also carries out RIP (rasterisation) and image processing etc. except the control of each portion.In addition, CPU11 also plays a role as judging part and operational part by control program.
Information (paper type and gloss, the thickness etc. of judging part based on relevant paper using, hereinafter referred to as use of paper message), the performance of relative assembly and the information of state (the accumulative total service time of Cmax value and consumptive material, consider that temperature and temperature carried out proofreading and correct to above-mentioned accumulative total service time regard the cumulative time etc. as, hereinafter referred to as device information), with reference to table described later, judgement printing form (could be subdivided into unit print still with two points or two lines etc. with the least unit of a point or a line etc. prints).In addition, judging part is being judged as can not segment in the situation that, contrast has been carried out the print data of obtaining by communication I/F portion 12 view data (being called source data) of rasterisation and has scanned to printed the paper using of image based on source data the view data (being called reading out data) reading, judge whether Yi Yigedian unit to print, or the reading out data based on the paper using that comprises the test pattern consisting of a point or line being scanned and reading, judges whether Yi Yigedian unit to print.
In addition, to adding up the service time of consumptive material, computing adds up service time to operational part, or the cumulative time of regarding as of temperature has been considered in the information based on obtaining from temperature sensor 50 and computing service time to accumulative total, or the information based on obtaining from IDC sensor 40 and computing Cmax value, or read the value of paper using counter and computing printing number.
12 establishments of communication I/F portion are connected with server, client computer, other devices etc., and the transmission of executing data receives.
HDD13 storage CPU11 is for controlling the information, device information, table described later of the processing capacity of the program of each portion and above-mentioned control program, relevant this device, above-mentioned source data etc., these are read out as required by CPU11, and are carrying out with carrying out and process on memory 17.
RIP video memory 14 is parts of the print data obtained from communication I/F portion 12 of interim storage, and the print data of storing implements rasterisation by CPU11 and image is processed, and in the judgement of can Yi Yigedian unit whether printing, is utilized.
The part of output image read memory 15 view data that to be interim storages obtain from output image reading part 20 or ADF30, the view data of storing is utilized when judging whether by CPU11 can Yi Yigedian unit to print.
Use of paper message is held the memory that memory 16 is the information inputted according to the judged result of operation inputting part 60 or CPU11 etc. of storage.In this use of paper message, hold the image results of comparison (information of fog-level) of also storing use of paper message (paper type, gloss, thickness etc.) and being undertaken by CPU11 in memory 16.
Carry out and be utilized when CPU11 carries out various program with memory 17.
Output image reading part 20 is the devices that read the output image forming in paper using, is high-precision CCD (charge coupled device) scanner that can read the least unit such as a point or a line.In addition, general scanner at last just, for example, by carrying out temporarily stopping paper using on CCD, or the control of moving paper using etc. with very slow speed, also can read the least unit such as a point or a line.In addition, the kind of scanner without particular limitation of, but because output image reading part 20 is arranged on the paper using carrying path of trimmer, while therefore preferably can move the such scanner of EDH (electric document processor) that paper using reads.In EDH scanner, not fixedly original copy moving images fetch unit and reading images, but still image fetch unit mobile original copy and therefore reading images can suppress the impact of scanning on productivity ratio.
Fig. 3 is embedded into image graph on the carrying path (paper trucking department) of paper using, output image reading part 20 by fine EDH scanner.In addition, due to the area of the reading part in scanner with read precision/read time interlock, if the region that therefore once can scan is wide, correspondingly can read at a high speed, but cost can rise certainly, therefore become trade-off relation with installation cost.
ADF30 is the part to output image reading part 20 by the original copy paper using automatic transporting of individual or multiple, has also added here from the part of the original copy paper using reading images of document board.The main purpose of this ADF30 is to duplicate and Manuscript scanner, but also can be used for replacing output image reading part 20.But, at this moment need manually output to be transported to ADF30, and operate and carry out output image and read indication and input etc. by hand.
IDC sensor 40 is densimeters of reading images concentration, measures the concentration of the spot (patch) in transfer belt.Fig. 4 and Fig. 5 are that Fig. 4 is side cross-sectional view for the skeleton diagram of this mechanism is described, Fig. 5 is top view.In Fig. 4 and Fig. 5, record two drums (development section A, B) that develop, but the in the situation that of color printer, generally can arrange 4 this development drums.In addition, can in black-and-white printer, be also 1 sometimes, in special color printer, be more than 5.The toner image generating in this development section is transferred in paper using via transfer belt in transfer section, region by the outside that can not be transferred to paper using in transfer belt is placed toner and measures its concentration, thus the state of can predict/judgment means and the concentration of final image.
Temperature sensor 50 is for example general thermocouple, the temperature of determinator inner/outer, and the signal corresponding to temperature (being the voltage corresponding to temperature in the situation of thermocouple) is sent to CPU11.
Operation inputting part 60 is the TIPs that carry out the control indication of apparatus main body.Owing to being made as touch panel here, therefore become one with Display panel portion 90, but this operating function is not limited on panel, as long as operating function can be provided, can be Anywhere.
The view data of image printing portion 70 based on reading from ADF30 or the view data of obtaining from communication I/F portion 12 has been carried out to the data of rasterisation, forms and prints the desirable image of user.Specifically, thereby from the lasing fluorescence portion of exposure device to by Charging system charged the laser that irradiates corresponding to image of photoconductor drum form electrostatic latent image, in developing apparatus, adhere to charged toner and develop, by this toner image primary transfer on transfer belt, and from transfer belt secondary transfer printing paper using, and then in fixing device, make toner image photographic fixing to the processing in paper using.
Collector lens adjustment part 80 is parts of above-mentioned image printing portion 70, is arranged on Ear Mucosa Treated by He Ne Laser Irradiation on the light path of photoconductor drum, carries out dwindling of laser beam.Conventionally dwindle to greatest extent, but because the combination based on lens is dwindled, therefore can increase as required the diameter of light beam.Fig. 9 is the figure that schematically shows collector lens adjustment part 80, thereby can change the beam diameter size on photoconductor drum by mobile mobile unit portion.
Display panel portion 90 is parts of the choice menus of display operation indication etc.This Display panel portion 90 becomes touch panel integratedly with operation inputting part 60, becomes the structure that can carry out various operations, but not necessarily will become one with operation inputting part 60.
In addition, Fig. 2 is an example of the image processing apparatus 100 of the present embodiment, and its structure can suitably change.For example, do not use considered temperature regard the cumulative time as during as device information, do not need temperature sensor 50, when not using Cmax value as device information, do not need IDC sensor 40.In addition,, when the side by output image reading part 20 or ADF30 reads the image of paper using, can omit the opposing party.In addition, then while being undertaken point/mono-'s line to be transformed to the processing of two point/twos' lines by printhead, do not need collector lens adjustment part 80.
Below, with reference to the action of the image processing apparatus 100 of the flowchart text said structure of Fig. 6.In addition, following processing/judgement is that CPU11 is with reference to each memorizer information etc. and carry out.
Image processing apparatus 100 is waited for until communication I/F portion 12 receives print data, if receive print data in printing queue, the print data receiving is carried out to RIP (rasterisation), is saved in HDD13 (S100) using it as source data.
Then, judgement printing mode be set to " point often " that with point/mono-'s line, print all the time, " two points often " that with two point/twos' lines, print all the time, which pattern (S101, S102) in " variable " that point/mono-'s line be transformed to two point/twos' lines.In addition, this printing mode presets by operation inputting part 60, or presets when factory's shipment.
When printing mode is " point often " (S101 is), owing to not needing later distribution judgement, therefore transfer to S118.In addition, when printing mode is " two points often " (S102 is), owing to also not needing later distribution judgement, therefore after having carried out again RIP in the setting that point/mono-'s line is transformed to two point/twos' lines (S116), the view data of preserving in HDD13 (source data) is rewritten as to RIP view data (S117) afterwards again, and transfers to S118.
On the other hand, when printing mode is " variable " (S101, S102 are no), the paper using used in this operation of judgement use of paper message whether be stored in use of paper message and hold (S103) in memory 16.In this use of paper message, comprise the paper usings such as common paper, colored dedicated paper, coated paper classification (paper type), density, component (thickness), size (size), process information such as (having or not of gloss finish).
When use of paper message is stored in use of paper message while holding memory 16, the device information of the operational part institute computing based on this use of paper message and CPU11, with reference in HDD13, store, by the table (table of Figure 11 and Figure 12) of use of paper message and device information and printing morphologic correlation connection (S104), judge with the least unit (hereinafter referred to as Yi Gedian unit) of a point or a line etc. and print, with the unit (hereinafter referred to as Liang Gedian unit) of two point/twos' lines etc., print or could realize their segmentation (S105).
Here, device information refers to accumulative total service time of the Cmax value of all kinds (being designated as Dmax concentration) measured by IDC sensor 40, consumptive material (here for transfer roll etc.) etc.If the accumulative total of this consumptive material is converted into service time, temperature while considering to use obtains, normal temperature environment is regarded the cumulative time as while using, and precision can be higher, therefore comparatively desirable.Figure 10 is for accumulative total being scaled based on temperature to an example of the table of regarding the cumulative time as service time.In addition, Figure 11 is that for use of paper message (paper type) and device information, (the Dmax concentration that whether meets black is more than 1.5 to regulation, and regarding the cumulative time as is less than 1000 hours) the example of table of printing form of combination, Figure 12 is regulation for an example of the table of the printing form of the combination of use of paper message (paper type) and device information (the Dmax concentration value of black and regard the cumulative time as).In addition, regarding the cumulative time as also can be based on the computing by the humidity of humidity sensor measuring, both sides that also can be based on temperature and humidity and computing.In addition, also can replace the cumulative time and use the Counter Value of paper using counter, also can and use both.
In the judgement of S105, be judged as in the situation of the printing of Yi Yigedian unit or the printing of Yi Lianggedian unit, print with this subdivided information interlock.On the other hand, be judged as can not segment in the situation that, the segmentation of carrying out based on reading of output image is a little judged.
In this judgement, first, reference (S106), is determined the read mode of output image for stipulating " setting of output image read mode " of reading which method/timing to carry out output image with.Should " setting of output image read mode " pre-enter by operation inputting part 60, or pre-enter in the initial value when factory's shipment, in the present embodiment, suppose to be set in 3 patterns (Mode A, B, C) shown below.In addition, output image read mode is not limited to these 3.
Mode A: generate the data of test pattern the method for sending before this operation;
Mode B: in the synthetic test pattern of blank parts of the first page of this operation the method for sending;
Pattern C: detect the part of point/mono-'s line in this operation, and judge the method for the segmentation of point/twos' point according to its result.
In the situation that being set as Mode A (S107 " Mode A "), before this operation, be different from this operation and generate in addition and measure the data of the test pattern of use for printing point/mono-line of one page, and deliver to output image reading part 20 (S108).Fig. 7 is the figure exemplified with the image of test pattern.
In the situation that being set as Mode B (S107 " Mode B "), in the blank parts of the initial page of this operation, (for example form test pattern that point/mono-line measures use, dwindle the image of Fig. 7 and be synthesized on four blank angles), and deliver to output image reading part 20 (S109).At this moment, due to human eye yellow not easy to identify (Yellow), therefore with point/mono-'s line of single yellow generation, thereby can make test pattern so unobvious.
In the situation that being set as pattern C (S107 " pattern C "), every one page is checked to point/mono-'s line in this operation all the time, after point/mono-'s line in detecting this image, judge whether to convert.At this moment, owing to sometimes switching unsatisfactory at same work image setting in the industry, therefore in S111, be judged to be in the situation that be applicable to conversion under the condition of this operation, preferably by operation inputting part 60, pre-enter or the initial value when factory's shipment in pre-enter and whether should in the way in this operation, switch.In addition, in the situation that do not carry out the setting that same work image setting in the industry switches, can export a certain judgement, but send the data for next operation in S114 after, in S115, do not convert switching, use the output of current RIP data until final page, and this operation release.
If more above-mentioned three patterns,, the in the situation that of Mode B, pattern C, do not need the paper usings (the only paper using of test pattern) that mensuration is special-purpose of printing more.But, the in the situation that of Mode B, there is following restriction: in the blank parts of positive facial tissue, have the test pattern of measuring use; Therefore owing to cannot carrying out the switching of point/mono-'s line of first, in first and its later page, may become different setting etc.In addition,, the in the situation that of pattern C, there is following restriction: sometimes in the way of this operation, can become different settings; Or it is medium to be only reflected to later operation next time.With respect to this, the in the situation that of Mode A, although follow the loss of paper using also to exist to spend more the expense activity duration shortcoming of (following productivity ratio to reduce some), there is no above-mentioned restriction, generally speaking think that balance is best, therefore can say that factory's shipment initial value is preferably set to Mode A.
Then, output image reading part 20, the in the situation that of Mode A, read and measure special-purpose paper using, the in the situation that of Mode B, read in blank parts and synthesized the initial page of the operation of test pattern, the initial page of reading operation in the situation that of pattern C, and store read view data into output image read memory 15 (S110).Then, CPU11 is to impinge upon in output image read memory 15 view data (reading out data) of preserving and the view data (source data) of preserving in RIP video memory 14, and only extracts a point/mono-line part and compare (S111).
Here, the in the situation that of Mode A, B, do not use output image reading part 20, by ADF30, can realize its effect yet.But, need to carry out the operation that the page of first is manually moved to ADF30 and measures.In addition, in the situation that using ADF30, also store read view data into output image read memory 15.
In above-mentioned contrast/relatively, the numerical data of the source data in RIP video memory 14 itself, for example, if line (becomes same value, K=100,100,100..., the in the situation that of Mode A, B, be therefore such value), in fact only with the reading out data in the output image read memory 15 in this place, to judge whether fuzzy.
For example, the data D (concentration) corresponding with data in the above-mentioned RIP video memory 14 that becomes same value, as D (concentration)=1.5,1.54,1.53,1.48... changes like this and is judged as " not having fuzzy " when little, as D (concentration)=1.50,1.02,0.95,1.48... is judged as " having fuzzy " when variation is larger like this.Specifically, resulting standard deviation value for measuring point etc. is compared with predetermined threshold value, when exceeding threshold value, (for example, standard deviation value be 0.03 when above) is judged as " having fuzzy ".Or, if relative concentration is 5% " not have fuzzy " with next being judged as in the ratio of low more than 20% pixel of mean value, while surpassing 5%, be judged as " having fuzzy ".
In above-mentioned judgement, in Mode A, B, must in first page, there is the test pattern of measuring use, therefore can descend effective judgement, but the in the situation that of pattern C, consider the measuring point that can judge not in this page or the situation of measuring point deficiency.Therefore, to judge whether to judge (in order judging, having obtained sufficient contrast information) (S112), in the situation that there is no sufficient contrast information, lower one page (S113) to be carried out to the processing of S110～S112.
While having obtained sufficient contrast information in S111, its Rule of judgment (paper type and Cmax) and judged result are saved in to use of paper message and hold memory 16 (S114).Thus, next time later identical conditions operation can judge and be made as Yi Gedian unit or Liang Gedian unit.
And, in this judged result for this operation, be for example, relative concentration is below 5% thereby " not having fuzzy " in the ratio of low more than 20% pixel of mean value, be made as (S115's is no) in the good situation of Yi Gedian unit, till using current view data (having carried out the view data of RIP in S100) to export last page to (S118), and output to discharge tray (S119), finish the action of this operation.
On the other hand, when this judged result is for example, relative concentration is more than 6% thereby " having fuzzy " in the ratio of low more than 20% pixel of mean value, be made as (S115 is) in the good situation of Liang Gedian unit, all adopt the setting of Liang Gedian unit to carry out again RIP (S116) the residue page of this operation, the view data of preserving in RIP video memory 14 is rewritten as to the view data after RIP again, with this view data, export (S118), and output to discharge tray (S119).
The modification of data when Fig. 8 represents above-mentioned RIP again.Here, on main scanning direction and sub scanning direction, scan twice, when detecting the part of a point or a line, to additional identical with this part information of the neighbor of scanning direction (in the situation of a point also the pixel to diagonal angle), with overstriking, data during RIP while making it with two dot patterns are identical.In addition, the method for a single point bit map Wei Lianggedian unit is not limited to said method.
In addition,, as additive method, do not carry out again RIP in addition but use source data, thereby change writes light beam by the method for a single point bit map Wei Lianggedian unit.Fig. 9 means the image graph that changes the method that writes light beam.As shown in Figure 9, in the situation that scioptics are gathered into the mode of the laser (writing laser) of picture use, by moving forward and backward mobile unit portion, adjust the position of lens, thereby can increase the beam diameter of laser, thus, part chap that can Shi Yigedian unit.
Like this, information based on relevant paper using (paper type and gloss, thickness etc.), the information of relative assembly (accumulative total service time of Cmax value and consumptive material, that has considered temperature in device and temperature regards the cumulative time etc. as), table with reference to Figure 11 and Figure 12, judgement could be subdivided into Yi Yigedian unit print or Yi Lianggedian unit print, be judged as can not segment in the situation that, reference source data and reading out data and judge whether Yi Yigedian unit to print, or the read test pattern based on whether and judge whether Yi Yigedian unit to print, be judged as can not Yi Yigedian unit print in the situation that, by carrying out a some Partial Transformation of the page image of operation, be the control of two points, thereby the fuzzy and breach that can suppress the image of the such least unit of a point or line.
