Description

Image processing apparatus and image processing method

Technical field

The present invention relates to image processing apparatus and image processing method, they can adjust the image from printer output Color.

Background technology

Compared with printer, the up-to-date improvement of the performance of electro-photography apparatus is that by high-quality image.But, The distinctive unstability of each electro-photography apparatus frequently can lead to the color change of electro-photography apparatus more than printer Color change.

It is said that in general, " monochromatic " collimation technique is generally applied in electro-photography apparatus.This " monochromatic " calibration skill Art includes generating for adjusting and each cyan, magenta, yellow and black (hereinafter referred to as C, M, Y and K) The inquiry table (look-up table, LUT) of the one-dimensional gray feature that powdered ink is corresponding.LUT is a form, this table Lattice indicate output data corresponding with in specific interval divided input data respectively.Use LUT can be with table Reach the nonlinear characteristic not being suitable for computing formula.Further, " monochromatic " is the single of use C, M, Y or K Powdered ink and the color reappeared.Perform monochrome calibration to can be used to adjust monochromatic recurring features, such as Cmax and gray scale.

As Japanese Laid-Open Patent Application JP2011-254350 is discussed, use " polychrome " calibration skill of four-dimensional LUT Art is the most recommended." polychrome " is the compound face using red, green and blue or ash (based on CMY) multiple powdered ink and reappearing Color.Especially, take the photograph physiognomy according to electronics, even if when using one-dimensional LUT to adjust monochromatic gradual change feature, if Use multiple powdered ink to show " polychrome ", then will produce nonlinearity erron.In this case, polychrome calibration is performed It is beneficial to adjust the polychrome recurring features that can be showed by the combination (such as superposition) of multiple color toner.

The calibration process process calibrated including " polychrome " will hereinafter be described.First, based on can be used for performing " list Color " the monochromatic chart data calibrated, record medium (such as opening paper) prints fragment (patches).Then, The fragment printed is read by scanner or sensor.The fragment data being read is compared with the desired value arranged in advance Relatively, and generate one-dimensional LUT for adjusting the difference between the fragment data and desired value being read.Then, base In the polychrome chart data of the one-dimensional LUT acquired in reflection, fragment is printed on record medium to perform " polychrome " Calibrate, and the fragment printed is read by scanner or sensor.Further, the fragment data being read with The desired value arranged in advance compares, and generates four-dimensional LUT, for adjusting the fragment data and target being read Difference between value.

As it has been described above, adjust can not be calibrated, by " monochromatic ", the many color characteristics adjusted by performing " polychrome " calibration, High-precision adjustment can be realized.

Additionally, as it has been described above, start to process from " monochromatic " calibration, it is desirable for then performing " polychrome " calibration.So And, not only complete monochromatic calibration but also complete the process time that polychrome calibration needs are considerably long.Such as, if user continually Perform monochrome to print, then very possible execution monochrome calibration, is not frequently executed because " polychrome " prints.Additionally, In electro-photography apparatus, there is such a trend: compared with processing with " monochromatic ", will produce non-in " polychrome " process Linearity error.So, even if in the case of " monochromatic " feature is fully adjusted, " polychrome " feature is likely not to have is filled Ground is divided to adjust.Therefore, in the case of user frequently executes " polychrome " (such as photo) printing, it is likely that execution is many Color is calibrated and polyenergetic calibration.

In response to above-mentioned user's request, there is a kind of machinery, it provides two independent buttons to allow users to The calibration of selection monochrome respectively and polychrome are calibrated, and independently execute selected calibration (reference Fuji-Xerox 2010 No. 19 technical report).

But, according to the above-mentioned technology discussed in Fuji-Xerox's No. 19 technical report in 2010, monochromatic calibration Process and the execution of polychrome calibration process is independent.So, if main (the most frequent) performs two kinds of calibrations One, then the Adjustment precision calibrated may decline.

One of " the monochromatic calibration " for adjusting monochromatic gradual change feature that export from printer 115 is described in conjunction with Fig. 3 Example.Perform monochrome calibration to be conducive to adjusting monochromatic chromatic rendition feature (such as Cmax feature and gray feature). When performing calibration, the C used with printer 115, M, the Y color rendition feature corresponding with K toner can be by Adjust together.More specifically, C, M, Y and K color can be performed by the process in flow chart shown in Fig. 3 simultaneously.

Fig. 3 is flow chart, illustrates the processing procedure generating the 1D-LUT218 in order to adjust single color gradation feature. CPU103 performs the process of flow chart shown in Fig. 3.Storage device 121 stores the 1D-LUT218 generated.Display Equipment 118 display includes to the UI screen of user instruction message.Input equipment 120 receives the instruction from user.

In step S301, CPU103 obtains the chart data " A " 302 being stored in storage device 121.Chart numbers According to " A " 302 for adjusting the Cmax of each monochrome.Chart data " A " 302 includes signal value (such as 255), It is obtained in that C, M, Y and K " monochromatic " respective Cmax data based on this signal value.

It follows that in step S303, CPU103 makes graphics processing unit 114 hold chart data " A " 302 Row image procossing, and make printer 115 print plot " A " 304.Fig. 5 A illustrates based on chart data " A " 302 One example of the chart 501 printed.Chart 501 include respective C, M, Y and K color with its Cmax 4 fragments 502,503,504 and 505 printed.In this case, graphics processing unit 114 only carries out step Halftone process in rapid S214.Graphics processing unit 114 does not perform the 1D-LUT adjustment in step S213 and processes, The most do not perform the 4D-LUT adjustment in step S212 to process.

It follows that in step S305, CPU103 scanner 119 or be arranged on the sensing in measuring unit 126 The concentration of the printed product of chart " A " 304 measured by device 127, and obtains measured value " A " 306.Measured value " A " 306 Represent the concentration value of each C, M, Y and K color.It follows that in step S307, CPU103 reference Measured value " A " 306 and the desired value " A " 308 of Cmax value that is typically preset are to adjust the measured value of each color The Cmax of " A " 306.According to this illustrative embodiments, CPU103 adjusts the equipment of printer 115 and arranges Value, such as laser output and development deviation, in order to make Cmax equal with desired value " A " 308.

It follows that in step S309, CPU103 obtains the chart data " B " 310 being stored in storage device 121. Chart data " B " 310 includes the signal value of " monochromatic " gradation data of C, M, Y and K.Fig. 5 B shows chart " B " 312, it includes being printed on the fragment on record medium based on chart data " B " 310.Chart shown in Fig. 5 B 506 is the beating of chart " B " 312 of multiple fragments including being printed on record medium based on chart data " B " 310 One example of print product.Chart 506 shown in Fig. 5 B includes 4 fragment groups 507,508,509 and 510, The each group of multiple gradation datas comprising C, M, Y and K color respectively.

It follows that in step S311, CPU103 makes graphics processing unit 114 perform chart data " B " 310 Image procossing.CPU103 makes printer 115 print plot " B " 312.In this case, graphics processing unit 114 only carry out the halftone process in step S214.Graphics processing unit 114 does not perform in step S213 1D-LUT adjustment processes, and does not the most perform the 4D-LUT adjustment in step S212 and processes.Step S307 prints Machine 115 has been performed for Cmax and adjusts.So, in this state, printer 115 is able to carry out and mesh Cmax generally equalized for scale value " A " 308 prints.

It follows that in step S313, CPU103 scanner 119 or sensor 127 perform measurement, and obtain Measured value " B " 314.Measured value " B " 314 represents the concentration value that can obtain from each C, M, Y and K color gray scale. Then, in step S315, CPU103 generates 1D-LUT218 and is used for based on measured value " B " 314 and setting in advance The desired value " B " 316 put adjusts single color gradation feature.

It follows that combine Fig. 4 to describe " the polychrome calibration " for adjusting many color characteristics from printer 115 output One example.Performing polychrome calibration is conducive to the combination (or superposition) adjusting the multiple color toner of use to represent many Color reproduction feature.The CPU103 arranged in the controller 102 is able to carry out following process.Storage device 121 is deposited 4D-LUT217 acquired in storage.Further, display device 118 display comprises to the UI of the instruction message of user Screen, and input equipment 120 receives the instruction from user.

After having performed monochromatic calibration, perform polychrome calibration, for adjusting the polychrome from printer 115 output.Cause This, it is desirable for being immediately performed polychrome calibration after completing monochromatic calibration.

In step S401, CPU103 obtain be stored in storage device 121 about " polychrome " chart data The information of " C " 402.Chart data " C " 402 is used for adjusting polychrome and includes that C, M, Y and K color combines " many Color " signal value.Fig. 5 C describes chart " C " 404, and it comprises beats on the recording medium based on chart data " C " 402 Multiple fragments of print.Fig. 5 C shows an example of the chart 511 printed based on chart data " C " 402 of knowing clearly.Bag The fragment 512 being contained in chart 511 and other fragments are to combine, as C, M, Y and K color, the polychrome being configured Fragment.

It follows that in step S403, CPU103 makes graphics processing unit 114 hold chart data " C " 402 Row image procossing, and promote printer 115 print plot " C " 404.In polychrome is calibrated, owing to completing monochromatic school After standard, many color characteristics of equipment are adjusted, so graphics processing unit 114 uses generation in monochrome is calibrated 1D-LUT218 performs image procossing.

It follows that in step S405, the sensor that CPU103 is provided by scanner 119 or measuring unit 126 The polychrome of 127 printed product measuring chart " C " 404, and obtain measured value " C " 406.Measured value " C " 406 table Many color characteristics of printer 115 after monochromatic calibration are shown.Further, measured value " C " 406 with equipment without The color space closed is defined.According to this illustrative embodiments, measured value " C " 406 is Lab value.If Use scanner 119 in measurement, then CPU103 uses the RGB that three-dimensional (3D)-LUT (not shown) will obtain Value is converted into Lab value.

It follows that in step S 407, CPU103 obtains and is stored in the Lab → CMY in storage device 121 3D-LUT409, and prior with in the Lab → CMY3D-LUT409 obtained by reflected measurement value " C " 406 Difference between the desired value " C " 408 arranged generates Lab → CMY3D-LUT (controlled) 410.Lab→ CMY3D-LUT is three-dimensional LUT, for the CMY value that output is corresponding with the Lab value of input.

As an object lesson of the method for generation, CPU103 is by between measured value " C " 406 and desired value " C " 408 Difference joins the Lab value of the Lab → CMY3D-LUT409 of input side, and utilizes Lab → CMY3D-LUT This difference of 409 pairs of reflection Lab values performs interpolation calculation.Therefore, CPU103 can generate Lab → CMY 3D-LUT (controlled) 410.

It follows that in step S411, CPU103 obtains and is stored in the CMY → Lab in storage device 121 3D-LUT412 also utilizes Lab → CMY3D-LUT (controlled) 410 to perform calculating.Thus, CPU103 Generate CMYK → CMYK4D-LUT217.CMY → Lab3D-LUT is three-dimensional LUT, for output with The corresponding Lab value of CMY value of input.

Will be detailed below the method for generating CMYK → CMYK4D-LUT217.CPU103 based on CMY → Lab3D-LUT412 and Lab → CMY3D-LUT (controlled) 410 generates CMY → CMY 3D-LUT.It follows that CPU103 generate in the way of making input value K equal with output valve K CMYK → CMYK4D-LUT217.CMY → CMY3D-LUT is three-dimensional LUT, for the CMY of output with input It is worth the CMY value of corresponding adjustment.

Fig. 6 illustrates the example allowing users to select the UI screen 601 of monochromatic calibration and/or polychrome calibration. Display device 118 can show UI screen 601 as shown in Figure 6.Button 602 is used for receiving beginning monochrome calibration Input.Button 603 starts the input of polychrome calibration for receiving.Button 604 completes monochromatic calibration for receiving Perform the input of polychrome calibration afterwards.

If selected for button 604, then CPU103 starts monochromatic calibration, and after completing the calibration of this monochrome, Start polychrome calibration.

More specifically, after completing monochromatic calibration, CPU103 starts polychrome calibration and prints polychrome calibration figure simultaneously Table " C " 404.Alternatively, CPU103 can make display device 118 display comprise the button for starting polychrome calibration UI screen, and if user press this button, start polychrome calibration.

On the other hand, if selected for button 602, CPU103 only carries out monochromatic calibration.It is similar to, if selected Button 603, then CPU103 only carries out polychrome calibration.

The reason that monochromatic calibration knob and polychrome calibration knob are separately provided is as follows.CPU103 is being printed for polychrome With reference to the 1D-LUT218 generated in monochrome calibration during the chart " C " 404 calibrated.Thus, calibrated in monochrome After one-tenth, in other words, after monochromatic recurring features is adjusted, it is immediately performed polychrome and calibrates to adjust many Color reproductions Feature is desirable.But, if CPU103 performs two kinds of calibrations, complete described calibration the most for a user Need the relatively long process time.

Therefore, in order to reduce the process time, it is contemplated that use environment, CPU103 can make user select monochromatic calibration Or polychrome calibration.So, the frequency performing each calibration may is that variable.Such as, if user is frequently performed list Color prints, then the frequency performing polychrome calibration can reduce.On the other hand, if user is frequently performed multi-color printing (example As photo prints), then the frequency performing polychrome calibration can improve.

Additionally, when user can select desired button on the color adjustment menu of UI screen 601, limit the time It is favourable.

Generally, the power supply of image processing apparatus is closed at night and is opened in morning next day.So, in response to opening The power supply of MFP101, it is allowed to user select button 604 is useful.Alternatively, if two kinds of calibrations are predetermined The most be not performed within time, then it is useful for allowing user select button 604.Alternatively, if predetermined number Before the paper of amount is used for printing, two kinds of calibrations are not the most performed, then allowing user select button 604 is to have ?.

Further, if the scheduled time is through afterwards, or the paper of predetermined quantity is used for printing, or power supply is beaten Open, then monochromatic calibration and polychrome calibration can perform the most automatically.

As it has been described above, this system is configured to: when user performs calibration in the scheduled time, it is allowed to user only selects to press Button 604, and after completing monochromatic calibration at preset time intervals, prompting user selects polychrome to calibrate immediately.

As it has been described above, user can select to be to perform polychrome calibration (i.e. performing two kinds of calibrations) after completing monochromatic calibration, Or or perform monochrome calibration or perform polychrome calibration.Thus, it is contemplated that to the use condition of user, calibration can be fitted When execution.

Further, system can perform control to allow user to select to perform two kinds of calibrations at preset time intervals, and Prevent the reduction of the Adjustment precision of recurring features in the calibration caused because being not carried out one of two kinds of calibrations.

603 are pressed the button to select the operation of polychrome calibration it follows that be described below.When being used for only carrying out polychrome school When accurate button 603 is pressed, CPU103 promotes display device 118 to show UI screen, and this UI screen request is used Family judges whether to perform monochrome calibration before starting polychrome calibration.This UI screen shows and desirably prevents because not performing The reduction of the Adjustment precision of the polychrome calibration that monochrome is calibrated and caused.The flow chart of Fig. 7 illustrates when selecting polychrome calibration One example of the process of Shi Zhihang calibration process.Arrange CPU103 in the controller 102 to perform such as Fig. 7 institute The following process shown.Storage device 121 stores acquired data.Further, display device 118 display comprises To the UI screen of the instruction message of user, input equipment 120 receives the instruction from user.

In step s 701, CPU103 starts polychrome calibration.More specifically, when user is by input equipment 120 When pressing the button 603 shown by display device 118, start polychrome calibration.

It follows that in step S702, CPU103 shows the UI screen requiring that user judges whether to perform monochromatic calibration Curtain.Fig. 8 illustrates by an example of the UI screen 801 shown by display device 118.UI screen 801 includes Message field 802, shows that in this message field monochromatic recurring features is suitable condition in performing polychrome calibration Under (monochromatic calibration have been carried out under conditions of), perform the message of monochromatic calibration for pointing out user to judge whether. UI screen 801 includes two buttons 803 and 804, it is possible to makes user judge whether in advance and performs monochromatic calibration.If Select button 803 "Yes", then CPU103 performs monochrome calibration.If select button 804 "No", then CPU103 Do not perform monochromatic calibration.

It is chosen in the calibration of each polychrome and is performed before in polychrome calibration, UI screen 801 can be shown.Optional Ground, when the quantity of polychrome calibration that can be performed after the most monochromatic calibration is beyond threshold value, shows UI Screen 801.Such as, in performing calibration, when polychrome calibration is continuously performed five times, UI screen can be shown Curtain 801.

In step S703, CPU103 judges whether to perform monochromatic calibration in advance.More specifically, CPU103 judges User have selected button 803 or button 804 on UI screen 801.

If it is determined that monochromatic calibration is not performed (for "No" in step S703), then in step S704, CPU103 Execution polychrome is calibrated.The process that the process of execution is performed with step S401 to S411 in step S704 is similar Seemingly, so repeating no more.

If it is determined that monochromatic calibration is performed (for "Yes" in step S703), then, in step S705, CPU103 holds Row monochrome calibration.Then, in step S704, CPU103 performs polychrome calibration.The place performed in step S705 Manage the process performed with step S301 to S315 similar, so repeating no more.

In flow chart as shown in Figure 7, CPU103 continuously performs polychrome calibration after completing monochromatic calibration.But It is that it is useful for performing polychrome calibration to make user judge whether after completing monochromatic calibration.

By the above-mentioned process of flow chart shown in Fig. 7, before starting polychrome calibration, system may require that user judges Whether perform monochromatic calibration.In such manner, it is possible to prevent the adjustment essence in the polychrome calibration caused because not performing monochromatic calibration The reduction of degree.

It follows that when button 602 be pressed to select monochrome calibrate operation to be performed is described below.If used Family presses the button 602 and calibrates for only carrying out monochrome, then CPU103 makes display device 118 show UI screen, Require user to judge after completing monochromatic calibration and whether perform polychrome calibration.Such UI screen shows the most anti- The reduction of Adjustment precision in the calibration only caused because not performing polychrome calibration.

If as it has been described above, only order performs monochrome calibration, then system performs process, is used for requiring that user judges Whether perform polychrome calibration.

In the process above, as the result of request, when monochrome has been calibrated, user can refuse to hold continuously Row polychrome is calibrated.In the case, user can be continuing with reaching the printer of desired accuracy.

In view of said circumstances, system performs process as shown in Figure 9, and described process includes showing UI screen, with Just require user to judge after completing monochromatic calibration and whether perform polychrome calibration.

CPU103 in the controller 102 is set and performs the process of flow chart as shown in Figure 9.Storage device 121 The data that storage obtains.It addition, display device 118 display includes being shown to the UI screen of the instruction message of user, And input equipment 120 receives the instruction from user.

First, in step S901, CPU103 performs monochrome calibration.

More specifically, when user presses display button 602 on the display device 118 via input equipment 120, CPU103 starts monochromatic calibration.

The process performed in step S901 is similar, the most no longer with the process performed in step S301 to S315 Repeat.

Then, in step S902, CPU103 promotes display device 118 to show UI screen, in order to require user Judge whether to perform polychrome calibration.Figure 10 illustrates of the UI screen 1001 that can be shown equipment 118 display Example.UI screen 1001 includes message field 1002, and this message field shows for completing list to user's suggestion The message of polychrome calibration is performed after color calibration.UI screen 1001 includes two buttons 1003 and 1004, in order to allow User judges whether to perform polychrome calibration.If button 1003 "Yes" is selected, then CPU103 is carried out many Color is calibrated.If button 1004 "No" is selected, then CPU103 does not the most perform polychrome calibration.

When monochrome calibration is selected, UI screen 1001 just can be shown.Optionally, it is also possible to only upper The number of times of the monochromatic calibration performed after the calibration of secondary polychrome just shows UI screen 1001 when exceeding threshold value.Such as, holding During row calibration, after continuously performing five monochromatic calibrations, just show UI screen 1001.

In step S903, CPU103 judges whether to perform polychrome calibration.More specifically, CPU103 judges choosing In button be button 1003 "Yes" or button 1004 "No".

If it is determined that be not carried out polychrome calibration (for "No" in step S903), then CPU103 just terminates The process in flow chart as shown in Figure 9.

If it is determined that perform polychrome calibration (for "Yes" in step S903), then in step S904, CPU 103 perform polychrome calibration.The process performed in step S904 and the process performed in step S401 to S411 Similar, therefore repeat no more.

By the above-mentioned process in flow chart as shown in Figure 9, system can require that user judges complete two kinds of calibrations In monochromatic calibration after whether perform polychrome calibration.Therefore, system is prevented from after completing monochromatic calibration not performing Polychrome is calibrated.So, system is prevented from user and is not reaching to desired Adjustment precision in calibration and is continuing with Printer.

According to the processing procedure described in the first illustrative embodiments, as a kind of during user chooses two kinds of calibrations, CPU103 just requires that user judges whether to perform another kind of calibration.

But, as the result required, if two kinds of calibrations are by frequently and be consecutively carried out, then be accomplished by longer The process time.It addition, if it is considered that the use state of printer can be different according to each user, then Even if the one the most only performed in two kinds of calibrations, it is also possible to sufficiently adjusted result.Such as, In general, for comparing monochrome, polychrome is easier to change.Therefore, if user frequently generates many chromatic numbers According to, such as picture data, then compare with monochromatic calibration, perform polychrome calibration with upper frequency and obtain sufficiently Adjust result to may is that effectively.In the case, user can be by after continuously performing five polychromes calibrations Perform the mode of monochrome calibration, the execution frequency calibrated according to its micro-judgment.

Therefore in the second illustrative embodiments, if user sends the order performing polychrome calibration, then when wanting When asking user to judge whether performed monochromatic calibration before performing polychrome calibration, system is indicated in monochrome calibration last time The number of times of the most performed polychrome calibration.
