With reference to Fig. 2, system according to color example embodiment of the present invention, that be used to adjust print data comprises printer driver 130, be used for will from install at computing machine 100 and the application program 110 of operation (for example, document editor, image editor etc.) document that transmits is converted to the print data that is suitable for printer 200, and sends this print data to printer 200.Soft print data of drawing a design 130 conversions of the 150 pairs of printer drivers in unit is used the soft processing of drawing a design.When handling print data in the soft unit 150 of drawing a design, color look-up table (LUT) 170 provides the color adjusted value for final print data.The soft unit 150 of drawing a design comprises display unit 156, is used to show it has been used the soft print data of drawing a design and using.Described document can only comprise image or comprise image and the mixing of other data.
The soft unit 150 of drawing a design comprises: interface unit 151 is connected with printer driver 130; Print data acquiring unit 152 obtains the print data in the storage unit 131 that is stored in printer driver 130; The soft applying unit 153 of drawing a design is used the soft processing of drawing a design to the print data of being obtained by print data acquiring unit 152; Color-values is adjusted and input block 154, adjusts and the input color-values; Color look-up table updating block 155, the color-values of utilizing color-values adjustment and input block 154 to adjust is upgraded color look-up table 170.And display unit 156, show the print data of it having been used the color look-up table 170 after upgrading.
After this, with reference to Fig. 2 to Fig. 4 the processing of being carried out by the system according to color example embodiment of the present invention, that be used to adjust print data is described.
At first, when the user to application program (for example, Word processor, Photoshop etc.) when importing the order that is used for document printing (operation S201), printer driver 130 utilizes classic method that the data of the document of application program establishment are converted to printer 200 discernible print datas (operate S101 and operate S103).Be stored in (operation S105) in the storage unit 131 (for example, frame buffer) with being printed the print data that machine driver 130 is converted to the form that is suitable for printer 200.In example embodiment of the present invention, be apparent that to those skilled in the art the print data that is stored in the storage unit 131 will be sent to printer 200, and print from printer 200.In other words, when the print data that is converted into the form that is suitable for printer 200 is stored in the storage unit 131, if the user does not carry out the soft application of drawing a design (operation S107 and S202), the print data that then is stored in the memory buffer unit 131 is transmitted to printer 200, and exports (operation S118 and operation S119) by print processing from printer 200.
On the other hand, if when be converted into the print data that is suitable for printer 200 when being stored in the storage unit 131 user carry out the soft application of drawing a design (operation S107), then print data is used soft processings of drawing a design (operating S109 and S203).When having imported fill order in the predetermined amount of time of user after print data is stored in the storage unit 131 (for example, frame buffer), to carry out the soft application of drawing a design with the similar mode of situation of Print Preview application basically.
If select to carry out the soft application of drawing a design in operation S107, then print data acquiring unit 152 obtains the print data that is stored in the storage unit 131, and display unit 156 shows to the soft print data (operation S109 and S110) of drawing a design and handling of its application.When print data acquiring unit 152 obtained the print data that is stored in the storage unit 131, the soft applying unit 153 of drawing a design was applied to this print data with color look-up table 170, and provided soft to the user and draw a design (operation S210).In example embodiment of the present invention, can utilize known soft of those of ordinary skills to draw a design to use and soft drawing a design provides method.
When the user wishes to adjust the color of print data in the soft processing of drawing a design, color-values adjustment and input block 154 are by the soft color adjusted value of input window reception from user's print data of drawing a design, select such as brightness, contrast, color balance and preferred color, as shown in Figure 5 and Figure 6 (operation S111 and S212).As long as the user has imported new color adjusted value (operation S213) by color-values adjustment and input block 154, the color look-up table updating block 155 of the soft unit 150 of drawing a design just upgrades the new color adjusted value (operation S113 and S214) by color-values adjustment and input block 154 inputs in color look-up table 170.Then, the color look-up table 170 that the soft unit 150 of drawing a design will upgrade new color adjusted value therein (promptly, color look-up table after the renewal) is applied to print data, and display unit 156 shows the print data of it having been used the color look-up table after upgrading, carries out soft drawing a design (operation S114 and S215) to allow the user in real-time mode.
When finishing soft the drawing a design of print data, the display screen by as shown in Figure 6 determines whether to print has used soft print data of drawing a design (operation S115) to it.During print button on the display screen in pressing Fig. 6, change the color of print data, and send it to printer driver 130 (operation S116, operation S118) by interface 151 according to the color look-up table of upgrading back (revising the back).When receiving described print data at printer driver 130 places, color look-up table is upgraded inspection unit 132 and is checked whether upgraded color look-up table 170 (operation S204).When having upgraded color look-up table 170, the color look-up table 170 after color look-up table applying unit 133 will upgrade is applied to final print data, and final print data is sent to printer 200 to print from it.(operation S118, operation S119 and operation S205).On the other hand, when the user does not wish print print data in operation S115, revert to previous color look-up table 170 by the color look-up table 170 after will upgrading and stop this processing (operation S117 and S217).
According to example embodiment of the present invention, can use soft drawing a design by the final print data that a plurality of processing of being carried out by printer driver are obtained and handle and carry out the soft processing of drawing a design based on more accurate result.
After this, will describe in detail according to method another example embodiment of the present invention, that adjust the color of print data.
When the color of output image and the desirable color of user of wishing to print described print data with desirable color not simultaneously, the user can use the method for the color of revising original image or by using color adjustment label to revise the method for color in printer driver.Yet,, may damage original image according to preceding a kind of method.According to a kind of method in back, there is following problems, promptly the accurate color modification of revising of user is uncertain, and may have influence on other color.In addition, must the chop and change setting when printing.Therefore, the objective of the invention is to, when the configuration file of the printer that uses as the user has the color look-up table type, can easily revise this color look-up table, and the user can come print image with desirable color.
The ICC configuration file of the printer that uses in example embodiment has color look-up table (CLUT) type.Use 17 * 17 * 17CLUT to describe the notion of CLUT as the example of CLUT type below.
CLUT17 * 17 * 17 are divided into 17 grades respectively with rgb value, to mate black (CMYK) color of green grass or young crops product reddish yellow that the machine that will be printed is printed in advance.When rgb value is consistent with CLUT, in other words, when each rgb value is 17 multiple (multiple number), this rgb value is output as the CMYK value in the relevant position that is stored in CLUT.In Figure 14, the point on each angle is accurately consistent with 17 multiple.Yet internal point CP is accurately not consistent with 17 multiple.By using three-dimensional linear interpolation (trilinear interpolation) or tetrahedron interpolation (tetrahedralinterpolation) to predict corresponding rgb value with internal point CP with reference to adjacent color.In current example embodiment of the present invention, be apparent that to those skilled in the art the division numbers of CLUT can be 9 * 9 * 9,33 * 33 * 33 etc.
After this, with reference to the method for Fig. 8 to Figure 14 detailed description according to the color of the adjustment print data of another example embodiment of the present invention.
As shown in figure 10, printer user will be loaded into (as shown in Figure 12) on the printer driver 20 (operation S10) as the reference picture (RI) of color conversion reference.When reference image R I is loaded on the driver 20, handles acquisition reference image R I as printer profile by soft drawing a design, and this reference picture is presented at (operation S20) on the screen.Obtain reference image R I by the soft processing of drawing a design, thereby the color of actual print image can be shown.Next, handle to obtain to be used for classification chart GC that color selects as printer profile by soft drawing a design, and this classification chart GC is presented at (operation S30) on the screen.In current example embodiment of the present invention, can use form and aspect classification chart as classification chart GC.Yet, also can use XYZ classification chart or label classification chart.
When complete operation S30, the color that the user selects to revise in reference image R I (operation S40).For the color of selecting to revise, the user clicks color CC as shown in figure 10 or drags several color CC_1 and CC_2 as shown in figure 12.When color that the user has selected to revise in reference image R I, driver such as Figure 10 and CC, CC_1 and the CC_2 (operation S50) of on classification chart GC, selected color being shown as shown in Figure 12.
When the user operation select among the S40 be a zone rather than a color time, show that on classification chart GC all colors in this zone may make the user feel confused, therefore, can only show influences the representative in selected zone color.According to selected zone, this representative color can be one or more.
When the user has selected one among the S40 when regional in operation, be used to search for and represent the process of color as follows.
The grid (grid) of supposing the CLUT of printer profile is 17 * 17 * 17.For example, when the user drags one when regional in reference image R I, printer driver is carried out following calculating to each color in this zone.For example, when rgb value was RGB (154,234,64), the net point that may influence this color divided by 17, obtained having the value of first decimal with each color-values, was added on it 0.5, and removed value behind the radix point.That is, when RGB (154,234,64) divided by 17 o'clock, it becomes CLUT (9.0,13.7,3.7).When with 0.5 be added on it and after removing radix point value the time, promptly round off, it becomes CLUT (9,14,4).
This CLUT (9,14,4) value becomes and is used to represent color that the user selects allocation really.In order to be RGB with this value representation again, that each is on duty with 17.Therefore, CLUT (9,14,4) becomes RGB (153,238,68).
When all colors in the reference picture zone have all been used above-mentioned processing, obtain representing the CLUT group of the representative color in this zone.
When obtaining representing color, search is represented the consistent rgb value of color with this in this zone.When having this consistent rgb value, on user's reference image R I and classification chart GC, show corresponding rgb value.Yet, when not existing with the accurately consistent rgb value of this representative color, by the range formula of distance between two points in the usage space, search is positioned at the locational rgb value near this representative color, and shows on user's reference image R I and classification chart GC and should be worth accordingly.
As a reference, the range formula of distance between two points is as follows in the space.When 2 be (x1, y1, z1) and (x2, y2 in the time of z2), obtain the distance of point-to-point transmission in the space by following formula 1.
[formula 1]
When complete operation S50, user such as Figure 11 and shown in Figure 13 dragging at color CC, CC_1 and the CC_2 shown in the classification chart GC, and they are revised as different color NCC, the NCC_1 of the desirable color of user and NCC_2 (operation S60).In Figure 11 and Figure 13, represent to use the new configuration file of the amended color among the classification chart GC with NRI.
When revising color in classification chart GC in operation S60, printer driver calculates new CLUT (operation S70) by using amended color NCC, NCC_1 and NCC_2.This describes with reference to Figure 14.
At first, when generating new CLUT, when the amended R ' G ' B ' value of comparing with the rgb value before the modification changes, the edge effect of jumping such as tone may take place.Therefore, can generate new CLUT by minimizing this edge effect.The method that minimizes edge effect is as follows.
Rgb value before supposing respectively to represent to revise, represent that with CenterRGB amended R ' G ' B ' value, usefulness (Δ R, Δ G, Δ B) represents poor (CenterRGB-BeforeRGB) between two values with BeforeRGB.Next,, all input RGB are used Gauss (Gaussian) normal distribution curve, can obtain new CLUT by minimizing edge effect by using change among the amended CenterRGB as weights W.Represent relevant therewith conversion formula with following formula 2.
[formula 2]
(R
out，G
out，B
out)＝(R
in，G
in，B
in)+(ΔR，ΔG，ΔB)*W(R，G，B)
