Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram illustrating an example of a hardware configuration of an information processing apparatus applicable to a color profile adjustment apparatus.

  In FIG. 1, reference numeral 101 denotes a CPU that comprehensively controls each device and controller connected to the system bus 104. Further, the ROM 102 or the external memory 111 is necessary to realize a BIOS (Basic Input / Output System) or an operating system program (hereinafter referred to as an OS), which is a control program of the CPU 101, or a function executed by each server or each PC. Various programs to be described later are stored.

  Reference numeral 103 denotes a RAM which functions as a main memory, work area, and the like for the CPU 101. The CPU 101 implements various operations by loading a program necessary for execution of processing from the ROM 102 or the external memory 111 into the RAM 103 and executing the loaded program.

  An input controller 105 controls input from a keyboard (KB) 109 or a pointing device such as a mouse (not shown). A video controller 106 controls display on a display device such as a CRT display (CRT) 110. Although described as CRT 110 in FIG. 1, the display device is not limited to the CRT, but may be another display device such as a liquid crystal display. These are used by the administrator as needed.

  A memory controller 107 is provided in an external storage device (hard disk (HD)), a flexible disk (FD), or a PCMCIA card slot for storing a boot program, various applications, font data, user files, editing files, various data, and the like. Controls access to an external memory 111 such as a compact flash (registered trademark) memory connected via an adapter.

  A communication I / F controller 108 is connected to and communicates with an external device via a network (for example, the LAN 600 shown in FIG. 1), and executes communication control processing in the network. For example, communication using TCP / IP is possible.

  Note that the CPU 101 enables display on the CRT 110 by executing outline font rasterization processing on a display information area in the RAM 103, for example. Further, the CPU 101 enables a user instruction with a mouse cursor (not shown) on the CRT 110.

Various programs to be described later for realizing the present invention are recorded in the external memory 111, and are executed by the CPU 101 by being loaded into the RAM 103 as necessary. Further, definition files and various information tables used when executing the program are also stored in the external memory 111, and detailed descriptions thereof will be described later.
Furthermore, forms, various data, setting files, and the like used in the present embodiment are also stored in the external memory 111 or a database (not shown).
Next, the profile creation process in this embodiment will be described with reference to FIGS. Each step is executed by the CPU 101.
2 and 3 are flowcharts of the entire profile creation process.

  In step S201, the user specifies an adjustment profile file that is a profile to be adjusted this time. Also input the specified adjustment profile. The adjustment profile is a file in which a color conversion table (LUT information) used for matching the color display between devices is described.

  In step S202, an adjustment image file used to create an adjustment profile is designated. Also input the specified image file. The image file for adjustment is used when the color is adjusted in the subsequent steps.

In step S203, the adjustment routine is entered. In this adjustment routine, the table for changing the color to be output from the printer is adjusted by changing the output RGB value of the LUT. By this adjustment, the output RGB value with respect to the input RGB value of the profile is changed, and the color of the printed matter output from the printer is changed even with the same image data. In other words, the LUT can be changed by this adjustment so that the output product has the expected color.
In step S204, an input of a color to be adjusted by a user operation is received. The input of the color to be adjusted is accepted on the screen of FIG.
FIG. 10 is an image diagram showing an adjustment screen.

  In FIG. 10, the image of the image file captured in step S202 is displayed as an image before adjustment. When a dot in this image is clicked, the input RGB value and output RGB value for the clicked dot are displayed, and this output RGB value is changed to another value and confirmed. A coefficient is applied to the amount of change, and the points around the input RGB value that has been adjusted are changed on the LUT using a complementary operation. The new output LUT after the change is displayed in the numerical window of the screen and the 3D gamut.

In step S205, it is confirmed whether the record in the LUT instructed to be changed in step S204 is locked. Detailed description will be given with reference to FIG.
FIG. 4 is a detailed flow of step S205 “LUT lock confirmation” in FIG.

  Check the LUT lock once it has been adjusted, and when the color of that part is confirmed, there is no need to make any further changes to the color of that part. This is a process to prevent further adjustment.

  In step S401, it is determined whether there is a locked record in the record of the LUT whose color is to be changed. It is confirmed whether or not the input RGB of the record that has been adjusted currently exists in the adjustment history file and the output RGB value for the input RGB value matches. If there is no matching record, the process proceeds to END as it is. When it exists, it progresses to step S402.

A step S402 searches the history file for a record having the same input RGB value as the locked record. If there is a history adjustment record having the same input RGB value as the locked record, the row of the adjustment record is displayed blinking on the status screen of FIG.
In step S403, it is determined whether the locked record is also changed by the user's operation.

If change is selected, the process proceeds to step S404. If not changed is selected, the process proceeds to step S405. Note that changing a locked record means changing the color once determined.
In step S404, all the locks of the records having the input RGB values currently being adjusted (the LUT save file in FIG. 7) are released.

  In step S405, it is determined whether or not only the record that is not locked by the current adjustment is changed by the user's operation. If change is selected, the process proceeds to step S407. If not change is selected, the process proceeds to S406. Note that changing only the unlocked record means changing only the unlocked record without changing the locked record with the color near the changed color. Therefore, the user confirms the image by comparing the images.

In step S406, the LUT lock application flag is set as the lock flag of the LUT storage file in FIG. The LUT lock application flag is a flag used in the determination in step S207.
In step S407, the blinking of the record that was blinking on the status screen in FIG. 11 is stopped.

  Returning to FIG. 2, in step S207, the presence or absence of the LUT lock application flag determined in step S205 is confirmed. If there is an LUT lock application flag, the process proceeds to S206, and if not, the process proceeds to S208.

  In step S206, the LUT lock application flag determined in step S205 is deleted from the lock flag of FIG. 7, and the process returns to step S204 to perform adjustment again.

  In step S208, the LUT information (record) for which the lock flag is not set in the LUT save file in FIG. 7 is changed to the output RGB value according to the adjustment result, and saved in the temporary LUT save file in FIG. The LUT information (record) for which the lock flag is set is stored in the temporary LUT storage file of FIG. 8 with the output RGB values before adjustment. Records that have not been changed as a result of adjustment are stored in the temporary LUT storage area with the output RGB values as they are.

  In step S209, the image used for adjustment is displayed after color adjustment using the output RGB values in the temporary LUT storage area. This is for the user to determine how much the difference in color before and after the adjustment is visually observed on the screen. By using the adjustment profile before adjustment and the adjustment profile after adjustment, it is possible to confirm on the screen whether the intended adjustment is performed by displaying the image input in S202.

  In step S210, the previous adjustment history is read from the history file of FIG. The data read from the history file is the input RGB value of the grid point LUT that is affected (changed) by the adjustment. This information is used in step S211.

  In step S211, the previous adjustment history and the input RGB value adjusted this time are compared. The read adjustment history and the input RGB values of the grid point LUT affected by the current adjustment are compared one by one. The difference in the output RGB value is a record affected by the current adjustment. The record affected by this adjustment is memorized. This is stored in order to compare whether the adjustment once made is affected.

  In step S212, it is determined whether there is any output RGB value that differs in the same input RGB value table of the LUT. That is, it is a process for determining whether there is a record affected by the current adjustment. If there is even one location stored in S211, the process proceeds to step S213 to output an influence range alert. If there is no portion stored in step S211, the process advances to step S215 without outputting the influence range alert, and the history file is saved.

In step S213, the range of influence on the image is displayed on the screen of FIG. Details regarding this portion will be described with reference to FIG. As a result, the user can check the location affected by the current adjustment from the screen. Further, by pressing the “print” button on this screen, it is possible to print with the color of the screen, and it is possible to check the influence state on the image in the same way even on a paper medium.
FIG. 5 is a detailed flow of “display status of influence on image” in step S213 of FIG.

  In step S501, on the status screen of FIG. 11, the record with the matching output RGB blinks. That is, the row of the adjustment record associated with the output RGB value found in S212 is blinked. This is to visually indicate to the user whether past adjustments have been affected by this adjustment.

In step S502, an image of an adjustment record (for example, an image of a mountain landscape) that overlaps with the current adjustment is acquired according to the path of the adjustment image in FIG. 9, and an image of the current adjustment (an image that is currently adjusted, for example, (1) in FIG. 6 together with the image of the river flow.
In step S503, the process is repeated to search the entire image for each image displayed in step S502.
In step S504, for all dots in the image, it is checked whether the color is constructed using the input RGB values of the adjustment record found in S212.

  In step S505, the dot that matches the input RGB value as a result of the check in step S504 is blinked and displayed. The dots that do not match do not blink and remain normal.

  By repeating the processing from step S503 to S505, the user can visually confirm which side of the image the current adjustment affects in the current adjustment result.

Next, in order to select what adjustment is to be performed in (2) to (4) of FIG. 6, an image by a plurality of adjustments is presented. In step S506, an image of an adjustment record (for example, an image of a mountain landscape) overlapped with the current adjustment changed by the output RGB value by the current adjustment, and an image of the current adjustment changed by the output RGB value by the current adjustment. (Currently adjusted image, for example, river flow image) is displayed vertically at the image position of (2).
In step S507, the 3D gamut based on the output RGB value changed this time is displayed below the image position displayed in step S306.

  In step S508, an adjustment record image (for example, an image of a mountain landscape) that has been changed by the output RGB value of the overlapping history and an output RGB value of the overlapping history that has been changed this time, and the current output that has been changed by the overlapping history output RGB value. The adjustment image (currently adjusted image, for example, river flow image) is displayed vertically at the image position (3). As the output RGB value of the overlapping history, the output RGB value corresponding to the input RGB value of the adjustment record currently overlapped with the input RGB value as a key is used for the LUT currently in the temporary LUT storage area.

In step S509, the 3D gamut based on the output RGB values of the history superimposed under the image position in (3) is displayed. The output RGB values of the overlapping history are displayed using the values used in step S508.
In step S510, the center value of the output RGB value for the same input RGB value in the overlapping history as the current adjustment is calculated.

  In step S511, the calculated output RGB value of the median value is replaced with the LUT value used in tap S508 or step S509, and an image adjusted using this LUT (for example, an image of a mountain landscape), and this LUT The image of the current adjustment adjusted using (currently adjusted image, for example, river flow image) is vertically displayed at the position (4).

  In step S512, a 3D gamut based on the output RGB value (median value) of the calculation result is displayed below the image position of (4). The output RGB value of the calculation result is the one used in step S511.

  Returning to the flowchart of FIG. 3, in step S <b> 214, the process branches depending on the selection of the user in the display of the influence state on the image. When (2) “current adjustment” or (4) “complicated plan” in FIG. 6 is selected by the user, the process proceeds to step S215. If (3) “History XX adjustment” in FIG. 6 is selected, the current adjustment is not performed and the process proceeds to step S220.

In step S215, the history file shown in FIG. 9 is saved. There are two purposes for creating a history file. One is to check whether or not the previous adjustment is affected by “display the influence state on the image” in step S214. The other is to display past adjustments on the status screen of FIG. 11 showing the adjustments made so far.
In step S215, the adjustment result is saved in a history file. If the history file does not exist, create a history file.

Here, the history file of FIG. 9 will be described.
The contents stored in the history file are as follows.
・ Adjustment record ・ Path of image used for change ・ Date and time ・ Input RGB value and output RGB value of grid point LUT affected by adjustment

  The adjustment record is a record indicating the order of the adjustment. Each time an adjustment is added, the number of records is incremented by one. In other words, the number of adjustments performed in the adjustment record is managed. One adjustment record is not unique per record, and the same record number is given across several records. If there are a plurality of input RGB values changed by one adjustment, the same number is assigned to the adjustment record. It is unique by the two terms of input RGB value and adjustment record.

  As the adjusted image path, the path to the adjusted image is recorded. This makes it possible to call up and confirm an image later when referring to past adjustments in “display the influence state on the image”. The adjustment record and the adjustment image have the same path. For example, if the adjustment record is 1 and the adjustment image path is “C: \ image \ mountain landscape.jpg”, even if there is an adjustment record 1 in another line, the adjustment record 1 The path of the adjustment image is “C: \ image \ mountain landscape.jpg”.

  For the date and time, record the time of adjustment. Get the saved time from the system date and time. Thereby, it uses for the function which displays the date which adjusted in the status screen of FIG. Here, the adjustment record and the date and time are the same. For example, if the adjustment record is 1 and the date and time when the adjustment record is 1 is “2012/5/10 10:30”, the date and time will always be “2012” even if there is an adjustment record 1 in another row. / 5/10 10:30 ".

  As the input RGB value and output RGB value of the lattice point LUT affected by the adjustment, the input RGB value at the adjusted location and the output RGB value after the adjustment are recorded. As a result, when the effect display on the image is performed in step S214, it is used to determine whether or not the same input RGB value is being adjusted. In addition, records having the same “input RGB value” do not exist in the same “adjustment record”.

  In step S216, it is determined whether to lock the adjustment result. Whether or not the adjustment result is locked is determined by displaying a hop-up window and allowing the user to make a selection. If “lock” is selected, the process proceeds to S218. If “Do not lock” is selected, the process proceeds to S217.

  In step S217, the contents of the temporary LUT storage file of FIG. 7 are overwritten and stored in the LUT storage file of FIG. At this time, since it is determined not to lock, the lock flag is not set at the changed position.

  In step S218, since it is determined to be locked, the contents of the temporary LUT storage file of FIG. 6 are overwritten and stored in the LUT storage file of FIG. 7 while setting a lock flag for the changed LUT.

  In step S219, the adjustment history of this time is additionally displayed on the status screen of FIG. This history is displayed according to the history file of FIG. 9 stored in step S215.

  In the adjustment record of FIG. 11, the adjustment record of the history file is output. The file name at the end of the adjustment image path of the history file is output as the adjustment image. The date and time of the history file is output at the adjusted time.

In step S220, it is determined whether or not the adjustment is completed in accordance with the user operation. If the adjustment is complete, the process proceeds to S221. If the adjustment is still performed, the process returns to S202, and the adjustment is performed again. The user determines whether to perform the adjustment again, based on the display of the influence state on the image and information on the status window.
In step S221, a profile is created and output based on the LUT storage file of FIG. In the present embodiment, the output value is an RGB value, but it may be a CMYK value.

  As described above, the profile adjustment apparatus 100 as the information processing apparatus adjusts the profile for color conversion. The profile adjustment apparatus reads the profile to be adjusted (profile read) and is used to adjust the profile. Is read (image read), the profile output value is changed using the read image, the changed output value and the image used in the output value change are stored in association with each other, and other images are stored. When reading and changing the output value of the profile, it is determined whether or not a change related to the previously stored output value is made (change determination). The location where the value is changed is identified and displayed on the stored image.

  In addition, the previously stored image output using the output value changed using the other image and the other image output using the output value changed using the other image are displayed in comparison. .

  Further, the contrast display displays the image corresponding to the stored output value output using the previously stored output value and the other image output using the stored output value. .

  In addition, when the stored output value is prioritized, the stored output value is locked so as not to be changed, and the identification display identifies and displays the location corresponding to the locked output value on the stored image. To do.

  Further, when giving priority to the output value changed using another image, the locked output value is released (unlocked), and the profile data is corrected using the output value changed using the other image.

  As described above, according to the present embodiment, when adjusting a specified color within a gamut, a history of past adjustments is acquired, the effect of past adjustments is displayed, and color adjustment in profile creation is performed. Efficiency can be improved.

  In actual operation, when mapping (adjusting) the designated color of the same system, the mapping is always carried out while paying attention to the influence range. Specifically, whether or not there is an effect on the specified color that has been adjusted before, an image related to the specified color is output each time and the effect is confirmed, and the operator is forced to spend time on the confirmation work become.

Therefore, according to the present embodiment, when an influence occurs on the previously mapped designated color, priority is given to the newly performed mapping, or re-mapping is performed so as not to affect the previous mapping, or the compromise is made. It is possible to easily determine whether the plan is used and to reduce the labor of the operator.
