[0023] Hereinafter, this embodiment will be described. In addition, the embodiment described below is not an embodiment that unduly limits the content of the present disclosure described in the technical solution. Furthermore, the structures described in this embodiment are not necessarily all essential structural elements of the present disclosure.

[0024] Figure 1The block diagram illustrates the structural example of the color measurement system 10 of the present embodiment. The color measurement system 10 of the present embodiment includes a color measurement unit 12, an acquisition unit 15, and a processing unit 18. The processing unit 18 includes a display processing unit 19 and a comparison processing unit 20. In addition, the color measurement system 10 can include a display unit 22. The color measurement system 10 can be implemented, for example, by a colorimeter 30 described later, or by the colorimeter 30 and a terminal device 60 described later. In addition, it can be implemented in various ways such as communicating the colorimeter 30 with cloud computing.

[0025] The color measurement unit 12 performs color measurement. For example, the color measurement unit 12 measures the target color printed or the like on the printing medium and outputs the color measurement value as the color measurement result. The color measurement unit 12 can be implemented by a color measurement sensor or the like. The color measurement sensor can use, for example, a spectroscopic sensor. For example, the color measurement sensor can use a spectroscopic sensor made of MEMS (Micro Electro Mechanical Systems) or the like that can be mass-produced by wafer-level processing. The spectroscopic sensor is, for example, a sensor that detects the reflection spectroscopic spectrum. Specifically, the spectroscopic sensor can be implemented by, for example, a light source realized by using an LED or the like, an optical filter that selects and switches wavelengths by inputting the reflected light on the measurement surface of the light from the light source, and a light receiving device that measures the light amount of the reflected light passing through the optical filter. The optical filter can use a standard gauge or the like that is a wavelength filter using multiple interference of two opposed reflecting surfaces. By using the spectroscopic sensor to measure the reflection spectroscopic spectrum that measures the light amount of the reflected light at each wavelength of the reflected light, the color measurement of the target color is achieved. In addition, the color measurement sensor that realizes the color measurement unit 12 is not limited to such a spectroscopic sensor, and the color measurement sensor can also be realized by, for example, an image sensor. In addition, the color measurement unit 12 can also adopt a unit that measures not only the reflected light but also the transmitted light.

[0026] The acquisition unit 15 is a communication interface for acquiring the color measurement value measured by the color measurement unit 12. The acquisition unit 15 can be implemented by hardware such as a circuit device for communication or a program for communication. For example, the acquisition unit 15 can receive the data of the color measurement value from the color measurement unit 12 included in a device different from the device having the acquisition unit 15 via a wireless network or a wired network. The device having the acquisition unit 15 refers to, for example, the terminal device 60 described later, and the device different from the device having the acquisition unit 15 refers to, for example, the colorimeter 30 described later. In addition, for example, the acquisition unit 15 can also receive the data of the color measurement value from the color measurement unit 12 of the device existing in the same device as the device having the acquisition unit 15, and the device here refers to, for example, the colorimeter 30.

[0027] The processing unit 18 controls each part of the color measurement system 10. Although the processing unit 18 can be implemented by a processor of the processing unit 62 of the terminal device 60 described later, it can also be implemented by a processor of the processing unit 32 of the colorimeter 30 described later, or by both. The details will be described below. The processing unit 18 executes each process of the present embodiment based on the program of the present embodiment. This program is a program for causing a computer to function as each part of the present embodiment. The computer is, for example, a device having an operation unit, a processing unit, a storage unit, and an output unit. For example, the program of the present embodiment is a program for causing a computer to function as the display processing unit 19 and the comparison processing unit 20. This program is stored in an information storage medium, for example. That is, the color measurement system 10 of the present embodiment can execute each process of the present embodiment based on the program stored in the information storage medium. The information storage medium, which is a medium readable by a computer, is a medium for storing programs, data, etc., and its function can be realized by an optical disc, a hard disk device (HDD), a semiconductor memory, etc.

[0028] The display processing unit 19 performs display processing corresponding to the processing executed by the processing unit 18 based on the program of the present embodiment. For example, when the processing unit 18 acquires data of a color measurement value via the acquisition unit 15, the display processing unit 19 displays color data obtained based on the acquired color measurement value data in a predetermined area of the display unit 22. Specifically, although the display unit 22 is, for example, the display unit 68 of the terminal device 60, it can be the display unit 38 of the colorimeter 30 or another display device. In the following description, there are cases where the data of the color measurement value is simply referred to as the color measurement value, and cases where the color data is simply referred to as the color.

[0029] The display processing unit 19 performs display processing of a comparison graph formed by combining the reference color graph of the reference color area 100 and the sample color graph of the sample color area 110. The display processing unit 19 performs, for example, as Figure 2The process of displaying a square-shaped graphic image icon as the image icon of the comparison graphic as shown in E. In the following description, the image icon of the comparison graphic will be simply referred to as the comparison graphic. In addition, the comparison graphic is bisected by a diagonal line, and one is the image icon of the reference color graphic composed of the reference color area 100, and the other is the image icon of the sample color graphic composed of the sample color area 110. In the following description, the image icon of the reference color graphic will be simply referred to as the reference color graphic, and the image icon of the sample color graphic will be simply referred to as the sample color graphic. For example, the color measurement unit 12 measures the desired color in the sample that is the object of color measurement. When the acquisition unit 15 acquires the color measurement value of this color, the display processing unit 19 performs a display process in such a way that the sample color area 110 is filled with the sample color CS based on the color obtained from this color measurement value. Similarly, the display processing unit 19 performs a display process in such a way that the reference color area 100 is filled with the reference color CB. In addition, the reference color CB in the present embodiment is not limited to the color pre-stored in a storage unit (not shown) in the color measurement system 10. For example, the color based on the color measurement value measured by the color measurement unit 12 can also be set as the reference color CB. In addition, Figure 2 This is a diagram showing the case where the display unit 22 of the color measurement system 10 corresponds to the display unit 68 of the terminal device 60 described later. However, the display processing unit 19 can also perform a process of displaying the same screen on the display unit 38 of the colorimeter 30.

[0030] The comparison processing unit 20 compares the color value of the reference color CB set in the reference color area 100 with the color value of the sample color CS set in the sample color area 110. For example, the comparison processing unit 20 determines whether the reference color CB set in the reference color area 100 and the sample color CS set in the sample color area 110 are the same. The colors of the reference color CB and the sample color CS being the same means that the allowable conditions for color matching are satisfied, and the allowable conditions can be appropriately set by the user. For example, the comparison processing unit 20 determines that the reference color CB and the sample color CS are the same when the color difference ΔE between the reference color CB and the sample color CS is less than a given value. In addition, the allowable conditions can be other conditions regarding the color difference ΔE, conditions regarding the ambient light source, conditions for each color component, or conditions for the reflection spectral distribution. In addition, a combination of these conditions can also be the allowable conditions.

[0031] As described above, the color measurement system 10 of the present embodiment includes: an acquisition unit 15 that acquires color measurement values measured by the color measurement unit 12; a display processing unit 19 that performs display processing of a comparison graph formed by combining the reference color graph in the reference color region 100 and the sample color graph in the sample color region 110; and a comparison processing unit 20 that compares the color value of the reference color CB set in the reference color region 100 with the color value of the sample color CS set in the sample color region 110. Thus, by including the acquisition unit 15, the display processing unit 19, and the comparison processing unit 20, the color measurement system 10 of the present embodiment can perform color measurement using a comparison graph formed by combining the reference color graph in the reference color region 100 and the sample color region 110. Thereby, the user can clearly grasp the changes in the reference color CB and the sample color CS by color measurement and visual observation, and can obtain a color measurement result based on the color difference ΔE between the color value of the reference color CB and the color value of the sample color CS. Thereby, the user can perform color measurement corresponding to various use cases. Thereby, the color measurement system 10 can provide a user interface corresponding to various use cases in color measurement. For example, there is a case where the acquisition unit 15 acquires the color value of the sample color CS by performing color measurement, and there is a case where the color value of the reference color CB is acquired as described above. Therefore, when there is no appropriate user interface, the user may misjudge what is acquired by color measurement. Regarding this point, by applying the method of the present embodiment, the user can observe the comparison graph, and thus can easily grasp which one or both of the reference color CB and the sample color CS have changed.

[0032] In addition, the method of the present embodiment can also be implemented as a color measurement method. That is, the color measurement method of the present embodiment performs the following processing: acquiring color measurement values measured by the color measurement unit 12; performing display processing of a comparison graph formed by combining the reference color graph in the reference color region 100 and the sample color graph in the sample color region 110; and comparing the color value of the reference color CB set in the reference color region 100 with the color value of the sample color CS set in the sample color region 110. By setting it in this way, the same effects as described above can be obtained.

[0033] In addition, the method of this embodiment can also be implemented as a program. That is, the program of this embodiment causes the colorimetric system 10 to execute the following steps, namely: a step of obtaining the colorimetric value measured by the colorimetric unit 12; a step of performing display processing of a comparison graph composed of a reference color graph of the reference color area 100 and a sample color graph of the sample color area 110; and a step of comparing the color value of CB set in the reference color area 100 and the color value of the sample color CS set in the sample color area 110. By setting it in this way, the same effect as above can be obtained.

[0034] In addition, the user interface of this embodiment is not limited to the above-mentioned comparison graphics, and can also be a user interface composed of other image icons and comparison graphics. Figure 2 As shown in FIG. 1 , a user interface may be provided that combines a lock button icon 200 with a comparison graph. The lock button icon 200 is a button icon that switches the state of the reference color CB between a locked state and an unlocked state. Although the details of the locked state and the unlocked state will be described in detail in FIG. Figure 8 Although described below, by allowing the user to use the locked state and the unlocked state separately, appropriate color measurement can be implemented according to various use cases. For example, when the lock button icon 200 is in a state indicating the locked state, when the user selects the lock button icon 200 once, the lock button icon 200 changes from a state indicating the locked state to a state indicating the unlocked state. Then, when the user selects the lock button icon 200 again, the lock button icon 200 changes from a state indicating the unlocked state to a state indicating the locked state. Although the state indicating the locked state and the state indicating the unlocked state are different, for example, Figure 2 This can be achieved by using an image of a button, or other images can be used. Preferably, the image allows the user to intuitively understand the locked state and unlocked state. As described above, the display processing unit 19 implements a process of displaying the lock button icon 200 on the display unit 22. The lock button icon 200 is used to set whether to set the reference color CB of the reference color area 100 to a locked state or an unlocked state. By setting it in this way, the user can arbitrarily switch the state of the reference color CB to any one of the locked state and the unlocked state on the screen of the display unit 22. As a result, the color measurement system 10 can appropriately provide the user with a corresponding user interface according to the change of the use case.

[0035] In addition, for example, Figure 2As shown, it can also be set as a user interface formed by combining the first button icon 300 and the second button icon 310 with a comparison graphic. The first button icon 300 is a button icon for setting the reference color CB and is displayed at a position corresponding to the reference color area 100. The button icon for setting the reference color CB is a button icon for the user to switch between setting the reference color CB based on the existing color and setting the reference color CB based on the newly created color measurement according to the use case. The fact that the first button icon 300 is displayed at a position corresponding to the reference color area 100 means that the situation where the first button icon 300 has a stronger association with the reference color area 100 than the sample color area 110 is displayed at a position where the user can recognize it. The second button icon 310 is a button icon for setting the sample color CS and is displayed at a position corresponding to the sample color area 110. The button icon for setting the sample color CS is a button icon for the user to switch between setting the sample color CS based on the existing color and setting the sample color CS based on the newly created color measurement according to the use case. The fact that the second button icon 310 is displayed at a position corresponding to the sample color area 110 means that the situation where the second button icon 310 has a stronger association with the sample color area 110 than the reference color area 100 is displayed at a position where the user can recognize it. In this way, the display processing unit 19 performs the process of displaying the first button icon 300 for setting the reference color CB at a position corresponding to the reference color area 100 and the second button icon 310 for setting the sample color CS at a position corresponding to the sample color area 110. By setting it in this way, the user can easily switch the settings for the reference color CB and the sample color CS. As a result, the color measurement system 10 can provide the user with a user interface that can appropriately respond according to the use case. In addition, regarding the details after the user selects the first button icon 300 or the second button icon 310, it will be described later by using Figure 6 and Figure 7 In the following text.

[0036] In addition, for example, as Figure 2 shown, it can also be set as a user interface formed by combining the frame icon 400 with a comparison graphic. The frame icon 400 is an icon composed of a frame-shaped image that encloses the comparison graphic. The frame icon 400 is displayed in the same color as the color of the reference color area 100 or the sample color area 110 that has changed due to the last color measurement. For a specific screen example, it will be described in Figure 10This will be described later. That is, in the color measurement system 10 of the present embodiment, the display processing unit 19 performs processing to display the frame icon 400 on the display unit 22. The frame icon 400 is based on the color measurement value finally measured by the color measurement unit 12 and surrounds the comparison graph. Thus, the user can reliably grasp which of the reference color CB set in the reference color area 100 and the sample color CS set in the sample color area 110 is the color set by the last color measurement. Thus, the color measurement system 10 can provide a user-friendly user interface to the user.

[0037] The color measurement system 10 of the present embodiment is not limited to the content described above, and various modifications such as adding other structural elements can be implemented. Figure 3 and Figure 4 FIGS. are examples of the external views of the colorimeter 30 and the terminal device 60 constituting the color measurement system 10 of the present embodiment. In addition, Figure 3 and Figure 4 For example, as described above, the color measurement system 10 of the present embodiment can be constituted only by the colorimeter 30, and various modifications can be implemented. In addition, the appearance of the colorimeter 30 is not limited to Figure 3 or Figure 4 shown in the example, and the appearance of the terminal device 60 is not limited to Figure 3 shown in the example.

[0038] Figure 3 The colorimeter 30 shown, for example, has a substantially cubic shape, and a display unit 38, a color measurement button 40, and a cross key 42 are provided on its upper surface. In addition, a return button 44 and a power button 46 are also provided on the upper surface of the colorimeter 30. On the other hand, as Figure 4 shown, a color measurement unit 12 and a movable shutter 48 are provided on the lower surface of the colorimeter 30. The display unit 38 can be realized by, for example, a liquid crystal display or an organic EL display, and displays various information to the user. The color measurement button 40 is an operation device for instructing the colorimeter 30 to perform color measurement. For example, when the user presses the color measurement button 40, the colorimeter 30 performs color measurement using the color measurement unit 12. The cross key 42 is, for example, an operation device for indicating directions such as up, down, left, and right. The return button 44 is a button for performing a return operation also called a backward operation, and the power button 46 is a button for turning on and off the power of the colorimeter 30. The color measurement unit 12 is a unit realized by a color measurement sensor as described above, and for example, its shape in a top view is a substantially circular shape. The movable shutter 48 protects the color measurement unit 12 when the colorimeter 30 is not in use. For example, when the user does not use the colorimeter 30, the user performs an operation of moving the movable shutter 48 toward the color measurement unit 12 to close the movable shutter 48, so that external impacts and the like are not applied to the color measurement unit 12.

[0039] Figure 3 and Figure 4 The colorimeter 30 shown in the figure is shaped such that a user can hold it with one hand and perform a color measurement operation. For example, the user holds the side of the colorimeter 30 with the thumb, middle finger, ring finger, little finger, etc., and presses the color measurement button 40 or performs an operation of indicating a direction through the cross keys 42 with the index finger. However, Figure 3 and Figure 4 Taking the colorimeter 30 shown in the figure as an example, the colorimeter 30 may also be composed of other shapes.

[0040] The terminal device 60 is a communication terminal capable of communicating and connecting with the colorimeter 30, and is implemented by, for example, a smart phone or a tablet PC (Personal Computer). The terminal device 60 communicates and connects with the colorimeter 30 through wireless communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). The terminal device 60 has a display unit 68 and also has operation devices such as operation buttons. In addition, the display unit 68 is, for example, a touch panel, and the user performs various operations by touching the display unit 68 that is a touch panel.

[0041] Figure 5 FIG. is a block diagram showing a structural example of the color measurement system 10 including the colorimeter 30 and the terminal device 60. In addition, the color measurement system 10 including the colorimeter 30 and the terminal device 60 is not limited to Figure 5 the structure, and various modifications such as omitting some of its structural elements or adding other structural elements can be implemented.

[0042] The colorimeter 30 includes a color measurement unit 12, a processing unit 32, an operation unit 34, a storage unit 3, a display unit 38, and a communication unit 39. The color measurement unit 12 is implemented by a color measurement sensor as described above.

[0043] The processing unit 32 performs control processing for each part of the colorimeter 30 and each process of the present embodiment. For example, the processing unit 32 performs control processing for the color measurement unit 12 and acquisition processing for acquiring color measurement data from the color measurement unit 12. In addition, the processing unit 32 performs input processing for the operation information of the user input through the operation unit 34, reading processing for reading information from the storage unit 36, and writing processing for writing information to the storage unit 36. In addition, the processing unit 32 performs display processing for displaying information on the display unit 38, control processing for the communication of the communication unit 39, and so on. The processing unit 32 can be implemented by a processor. For example, each process of the present embodiment can be implemented by a processor that operates based on information such as a program and a memory that stores information such as a program. The memory is the storage unit 36. For the processor, for example, the functions of each part can be implemented by separate hardware, or the functions of each part can also be implemented by integrated hardware. For example, the processor can include hardware, and the hardware includes at least one of a circuit for processing digital signals and a circuit for processing analog signals. For example, the processor can also be constituted by one or more circuit devices or one or more circuit elements mounted on a circuit board. The processor can also be, for example, a CPU (Central Processing Unit). However, the processor is not limited to the CPU, and various processors such as a GPU (Graphics Processing Unit) or a DSP (Digital Signal Processor) can also be used. In addition, the processor can also be a hardware circuit implemented by an ASIC (Application Specific Integrated Circuit). In addition, the processor can also include an amplification circuit, a filter circuit, etc. for processing analog signals.

[0044] The operation unit 34 is an operation interface for inputting the operation information of the user. The operation unit 34 can be implemented by an operation device. If taking Figure 3 as an example, the operation unit 34 can be implemented by operation devices such as a color measurement button 40, a cross key 42, a return button 44, a power button 46, etc. However, the operation devices for implementing the operation unit 34 are not limited to these operation devices.

[0045] The storage unit 36 stores various kinds of information. For example, the storage unit 36 stores programs and data. The storage unit 36 functions as a working area for, for example, the processing unit 32 and the communication unit 39. For example, the storage unit 36 serving as a memory can be a semiconductor memory such as SRAM (Static Random Access Memory) or DRAM (Dynamic Random Access Memory), a register, or a hard disk device, etc. For example, by storing commands readable by a computer in the storage unit 36 serving as a memory and executing these commands by the processing unit 32 serving as a processor, the processing of each part of the processing unit 32 is realized. The commands here can be either a set of commands constituting a program or commands instructing the operation of the hardware circuit of the processor.

[0046] The display unit 38 displays various kinds of information to the user. The display unit 38 can be realized by various displays such as a liquid crystal display or an organic EL display, etc. The display unit 38 displays, for example, information required for the user to operate the colorimeter 30, various status information of the colorimeter 30, etc.

[0047] The communication unit 39 is a communication interface for wireless or wired communication with an external device. The communication unit 39 can be realized by hardware such as a communication ASIC or a communication processor, communication firmware, etc. For example, the communication unit 39 communicates with an external device such as the terminal device 60 through short-range wireless communication such as Bluetooth. Specifically, the communication unit 39 communicates with an external device through wireless communication conforming to the BLE (Bluetooth Low Energy) standard. Alternatively, the communication unit 39 can also communicate with an external device through other standard wireless communication such as Wi-Fi. In addition, the communication unit 39 can also perform wired communication based on standards such as USB.

[0048] The terminal device 60 includes a processing unit 62, an operation unit 64, a storage unit 66, a display unit 68, and a communication unit 69.

[0049] The processing unit 62 executes the control processing of each part of the terminal device 60 and the various processes of this embodiment. For example, the processing unit 62 executes input processing of the operation information of the user input through the operation unit 64, reading processing of reading information from the storage unit 66, writing processing of writing information to the storage unit 66. In addition, the processing unit 62 executes display processing of displaying information on the display unit 68, control processing of the communication of the communication unit 69, etc. The processing unit 62 can be realized by the above-mentioned processor, etc.

[0050] The operation unit 64 is an operation interface for inputting operation information of the user. The operation unit 64 can be implemented by an operation device. If Figure 3 is taken as an example, the operation unit 64 can be implemented by an operation device such as a touch panel of the display unit 68, operation buttons provided on the terminal device 60, etc. However, the operation devices for implementing the operation unit 64 are not limited to these operation devices.

[0051] The storage unit 66 stores various information. For example, the storage unit 66 stores programs and data. The storage unit 66 functions as a working area for the processing unit 62, the communication unit 69, etc., for example. For example, the storage unit 66 as a memory can be a semiconductor memory such as SRAM, DRAM, a register, or a hard disk device, an optical disk device. For example, the storage unit 66 as a memory stores commands readable by a computer, and these commands are executed by the processing unit 62 as a processor, thereby implementing the processing of each part of the processing unit 62.

[0052] The display unit 68 displays various information to the user. The display unit 68 can be implemented by various displays such as a liquid crystal display or an organic EL display, for example. In addition, the display unit 68 is implemented by, for example, a touch panel and also functions as the operation unit 64. The display unit 68 displays, for example, information required for the user to operate the terminal device 60, various status information of the terminal device 60 and the colorimeter 30, etc.

[0053] The communication unit 69 is a communication interface for performing wireless or wired communication with an external device. The communication unit 69 can be implemented by hardware such as a communication ASIC or a communication processor, communication firmware, etc. For example, the communication unit 69 communicates with an external device such as the colorimeter 30 through short-range wireless communication such as Bluetooth. Specifically, the communication unit 69 communicates with an external device through wireless communication based on the BLE standard. Alternatively, the communication unit 69 can also communicate with an external device through other standard wireless communication such as Wi-Fi. In addition, the communication unit 69 can also perform wired communication based on a standard such as USB.

[0054] Moreover, as described above, the processing of the color measurement system 10 of the present embodiment can also be implemented by, for example, the processing unit 62 of the terminal device 60. In this case, the processing unit 62 includes a reception unit 14, a processing unit 18, a display processing unit 19, and a comparison processing unit 20, and implements the processing of each of these parts. For example, the program of the present embodiment is installed on the terminal device 60 as an application program and stored in the storage unit 66, and this application program executes the processing of each of the reception unit 14, the processing unit 18, the display processing unit 19, and the comparison processing unit 20. Alternatively, the processing of the color measurement system 10 can also be implemented by the processing unit 32 of the colorimeter 30. In this case, the processing unit 32 includes a reception unit 14, a processing unit 18, a display processing unit 19, and a comparison processing unit 20, and executes the processing of each of these parts. For example, the program stored in the storage unit 36 executes the processing of each of the reception unit 14, the processing unit 18, the display processing unit 19, and the comparison processing unit 20. Alternatively, the processing of the color measurement system 10 can also be implemented by the distributed processing of the processing unit 32 and the processing unit 62.

[0055] Next, a screen example of the method to which the present embodiment is applied will be described in more detail. In addition, although the following screen examples are screen examples displayed on the display unit 68 of the terminal device 60, they can also be displayed on the display unit 38 of the colorimeter 30, or on both of them, and can be appropriately determined by the user. In addition, although the following screen example display processing is the processing implemented by the processing unit 62 as the display processing unit 19, in the following description, it is only described as the processing implemented by the display processing unit 19.

[0056] Using Figure 6 and Figure 7 screen examples to illustrate the method of setting the reference color CB and the sample color CS. For example, when the user selects Figure 2 the first button icon 300, Figure 6 the dialog box shown is displayed on the display unit 68 as the first selection menu screen. Similarly, when the user selects Figure 2 the second button icon 310, Figure 7 the dialog box shown is displayed on the display unit 68 as the second selection menu screen. In addition, although in Figure 6 the first selection menu screen is displayed as a dialog box, for example, the display processing unit 19 can also implement the display processing of changing from the Figure 2 screen to another screen, that is, the first selection menu screen. Regarding Figure 7The same applies to the second selection menu screen. That is, in the color measurement system 10 of the present embodiment, when the first button icon 300 is selected, the display processing unit 19 performs processing to display the first selection menu screen for selecting the reference color CB set in the reference color area 100. When the second button icon 310 is selected, the display processing unit 19 performs processing to display the second selection menu screen for selecting the sample color CS set in the sample color area 110. By setting it in this way, the user can perform detailed settings for the reference color CB and the sample color CS.

[0057] In Figure 6 the dialog box, there are displayed an option icon clearly marked as "input according to color measurement" shown in A1, an option icon clearly marked as "select from color history" shown in A2, an option icon clearly marked as "select from color samples" shown in A3, and an option icon clearly marked as "select from group" shown in A4. When the user selects the option icon clearly marked as "input according to color measurement" in A1, the color based on the color measurement value measured by the color measurement unit 12 is set as the reference color CB in the reference color area 100. In addition, when the user selects the option icon clearly marked as "select from color history" in A2, although not shown in the figure, the colors measured and stored in the storage unit 66 in the past are displayed in a manner that can be selected by the user. Then, the color selected by the user is set as the reference color CB in the reference color area 100. In addition, when the user selects the option icon clearly marked as "select from color samples" in A3, although not shown in the figure, the colors based on the predetermined color sample book stored in the storage unit 66 are displayed in a manner that can be selected by the user. In addition, the predetermined color sample book refers to, for example, PANTONE (registered trademark) and DIC colors (DIC is a registered trademark), etc. Then, the color selected by the user is set as the reference color CB in the reference color area 100. In addition, when the user selects Figure 6 the option icon in A4 clearly marked as "select from group", although not shown in the figure, a screen showing a list of color groups is displayed, and the reference color CB is set in the reference color area 100 based on the colors of the color group selected by the user. The color group refers to a set of colors that are comparison objects composed of n (n is an integer of 2 or more). That is, the option icon clearly marked as "select from group" in A4 is an icon for setting group color measurement.

[0058] In Figure 7In the dialog box, there are option icons clearly marked as "Input according to color measurement" as shown in B1, option icons clearly marked as "Select from color history" as shown in B2, and option icons clearly marked as "Select from color samples" as shown in B3. When the user selects the option icon clearly marked as "Input according to color measurement" in B1, the color based on the color measurement value measured by the color measurement unit 12 is set as the sample color CS in the sample color area 110. In addition, when the user selects the option icon clearly marked as "Select from color history" in B2, although not shown, the colors that have been color-measured and stored in the storage unit 66 in the past are displayed in a selectable manner for the user. Then, the color selected by the user is set as the sample color CS in the sample color area 110. In addition, when the user selects the option icon clearly marked as "Select from color samples" in B3, although not shown, the colors based on the predetermined color sample book stored in the storage unit 66 are displayed in a selectable manner for the user. Additionally, the predetermined color sample book refers to, for example, PANTONE or DIC colors, etc. Then, the color selected by the user is set as the sample color CS in the sample color area 110. Additionally, in Figure 7 the dialog box, there is no display of Figure 6 the option icon A4 clearly marked as "Select from group". As described above, this icon is an icon for setting group color measurement based on a color group. Although it is related to the setting of the reference color CB, it is not related to the setting of the sample color CS. As described above, in the color measurement system 10 of the present embodiment, the display processing unit 19 performs processing to display the color selected based on at least one of the color samples, color measurement values, color history values, and reference color group in the first selection menu screen as the reference color CB, and performs processing to display the color selected based on at least one of the color samples, color measurement values, and color history values in the second selection menu screen as the sample color CS. By setting it in this way, the user can obtain the reference color CB and the sample color CS through various methods. Thus, the user can handle various use cases.

[0059] Although a method corresponding to a use case of setting an existing color as a reference color CB and a color to be measured as a sample color CS has been known, there are also use cases where the reference color CB is not an existing color and use cases where the sample color CS is not the color to be measured, and thus the existing method cannot handle them. Regarding this, by applying the method of the present embodiment, the user can perform color measurement corresponding to various use cases. As a result, the color measurement system 10 can provide a user-friendly user interface to the user. In addition, a use case where the reference color CB is not an existing color means, for example, after producing a sample containing a color based on a request from a user who is a printer, due to a change in the requested color or other reasons, confirming whether the produced sample is within an allowable range with respect to the new requested color. In this case, since the existing color is not registered in the color measurement system 10, the user first needs to perform color measurement on a sample containing the newly requested color and set it as the reference color CB. In addition, a use case where the sample color CS is not the color to be measured means, for example, confirming whether there is a problem in the color measurement system 10 in setting an existing color as the sample color CS because there is a large deviation between the color measurement result of the sample to be measured and the designed result. After that, for the setting of the reference color CB, the user selects Figure 6 "Input according to color measurement" shown in A1, and for the setting of the sample color CS, the user selects Figure 7 "Input according to color measurement" shown in B1 will be described. Although such use cases include the first use case described below using Figure 9 and the second use case described below using Figure 12 , other use cases can also be considered.

[0060] Next, the difference between the above-mentioned locked state and unlocked state will be described in detail using Figure 8 . Here, it is assumed that the acquisition unit 15 acquires a color measurement value based on the color CM1 in the first color measurement, a color measurement value based on the color CM2 in the second color measurement, a color measurement value based on the color CM3 in the third color measurement, and a color measurement value based on the color CM4 in the fourth color measurement.

[0061] When the state of the reference color CB is in the locked state, in the first color measurement, the color CM1 is set in the reference color area 100. In the second color measurement, while maintaining the state where the color CM1 is set in the reference color area 100, the color CM2 is set in the sample color area 110. In the third color measurement, while maintaining the state where the color CM1 is set in the reference color area 100, the color CM3 is set in the sample color area 110. In the fourth color measurement, while maintaining the state where the color CM1 is set in the reference color area 100, the color CM4 is set in the sample color area 110. Thus, the state of the reference color CB being in the locked state means that the reference color CB set in the reference color area 100 is the initially set color CM1, and in subsequent color measurements, the reference color CB is also maintained as the color CM1.

[0062] On the other hand, when the state of the reference color CB is in the unlocked state, in the first color measurement, the color CM1 is set in the reference color area 100. In the second color measurement, while maintaining the state where the color CM1 is set in the reference color area 100, the color CM2 is set in the sample color area 110. Then, in the third color measurement, the unlocked state is different from the above-mentioned locked state in that the color CM2 is set in the reference color area 100 and the color CM3 is set in the sample color area 110. Similarly, in the fourth color measurement, the unlocked state is different from the above-mentioned locked state in that the color CM3 is set in the reference color area 100 and the color CM4 is set in the sample color area 110. Thus, the state of the reference color CB being in the unlocked state means the case where the color of the sample color CS in the previous color measurement is set in the reference color area 100 through the current color measurement. In addition, although the detailed content will be described later using Figure 14 and Figure 15 and will be described below, the sample color CS is displayed in the reference color area 100 through the third color measurement, and the reference color CB is displayed in the reference color area 100 through the fourth color measurement. Since these operations will be repeatedly performed later, it is also considered that the display processing unit 19 is performing a toggle display process.

[0063] Next, use Figure 9 、 Figure 10 、 Figure 11 to illustrate the first use case suitable for the case where the state of the reference color CB is in the locked state and the screen example of the color measurement in this first use case. As Figure 9As shown, the first use case is a use case in which the color of one sample is set as the reference color CB and the colors of multiple samples are set as the sample color CS. Additionally, in the following description, the action of measuring the color of the color that is the colorimetric target attached to the sample will be simply described as measuring the color of the sample. Similarly, the action of measuring the color of the color that is the colorimetric target attached to the sample will be simply described as measuring the color of the sample. Furthermore, for example Figure 9 The color CB11 shown is the color that is displayed on the display unit 68 as a result of measuring the color of sample 1-1, and in the following description, it will be simply described as the color CB11 of sample 1-1. In Figure 9 the other colors and Figure 12 the colors are the same. Specifically, although the color set in the reference color region 100 is only the color CB11 of sample 1-1, the colors set in the sample color region 110 are the four colors, namely, the color CS11 of sample 1-1, the color CS12 of sample 1-2, the color CS13 of sample 1-3, and the color CS14 of sample 1-4. In such a case, by setting the state of the reference color CB to the locked state, after measuring the color of sample 1-1, the colors of samples 1-1 to 1-4 are measured, whereby the color CB11 can be compared with the color CS11, the color CB11 can be compared with the color CS12, the color CB11 can be compared with the color CS13, and the color CB11 can be compared with the color CS14.

[0064] Figure 10 , Figure 11 FIG. is a diagram showing a specific screen example and its transition of the color measurement in the first use case. When the user starts a predetermined application program of the terminal device 60, the display processing unit 19 displays the screen shown in C0 on the display unit 68. When this application program is just started, as shown in C1, the reference color region 100 is displayed in black, and as shown in C2, the sample color region 110 is also blank. In this case, the second button icon 310 cannot be used by the user. That is, in the color measurement system 10 of the present embodiment, when the reference color CB is not set in the reference color region 100 and the sample color CS is not set in the sample color region 110, the display processing unit 19 performs display processing to make the second button icon 310 unusable. By setting it in this way, the user can prevent the situation where the sample color CS is set in the sample color region 110 in a state where the reference color CB is not set in the reference color region 100. Thereby, for example, problems such as the occurrence of an abnormal condition in the application program of the terminal device 60 can be avoided.

[0065] Specifically, as shown in C3, the display processing unit 19 performs display in such a way that the second button icon 310 is grayed out, but it is not limited thereto. For example, it can also be displayed in a semi-transparent manner, or the second button icon 310 can be temporarily deleted, which can be appropriately set by the user. That is, in the color measurement system 10 of the present embodiment, when the reference color CB is not set in the reference color area 100 and the sample color CS is not set in the sample color area 110, the display processing unit 19 performs display processing to gray out the second button icon 310. By setting it in this way, the user can understand that the second button icon 310 cannot be used. Thus, problems such as the occurrence of bad conditions in the application program of the terminal device 60 can be avoided.

[0066] In the screen shown in C0, as shown in C4, the lock button icon 200 is displayed in a form indicating that the state of the reference color CB is the locked state. In the locked state, when the user selects the button icon shown in C5, the first color measurement is performed, and the screen shown in C0 changes to the screen shown in C10. In addition, in the screen example of C10, the symbols of the reference color area 100, the sample color area 110, the lock button icon 200, the first button icon 300, and the second button icon 310 are omitted. The same applies to the screen examples of C20 and C30. In the screen of C10, as shown in C11, the color CB11 of sample 1-1 is set in the reference color area 100. In addition, as shown in C12, the time information of the color measurement related to the color CB11 is displayed. In addition, as shown in C13, the second button icon 310 becomes the same display mode as the first button icon 300. Thus, the user can understand that the second button icon 310 can be used. In addition, the frame icon 400 is displayed in the same color as the color CB11 related to the last color measurement performed.

[0067] Then, when the user selects the button icon shown in C14, the second color measurement is performed, and the screen shown in C10 changes to Figure 11 the screen shown in C20. In the screen of C20, as shown in C21, the color CS11 of sample 1-1 is set in the sample color area 110. In addition, as shown in C22, the time information of the color measurement related to the color CS11 is displayed. In addition, the frame icon 400 is displayed in the same color as the color CS11 related to the last color measurement performed.

[0068] Then, when the user selects the button icon shown in C23, the third color measurement is performed, and the screen shown in C20 changes to the screen shown in C30. In the screen of C30, as shown in C31, the color CS12 of Sample 1-2 is set in the sample color area 110. In addition, as shown in C32, the time information of the color measurement performed for the color CS12 is displayed. In addition, the frame icon 400 is displayed in the same color as the color CS12 related to the last color measurement performed. In addition, regarding the case where the color CS13 of Sample 1-3 is displayed by the fourth color measurement and the case where the color CS14 of Sample 1-4 is displayed by the fifth color measurement, since it is the same as the description of Figure 11 it is omitted.

[0069] Next, use Figure 12 , Figure 13 , Figure 14 , Figure 15 to illustrate the second use case applicable when the reference color CB is in the unlocked state and the screen example of the color measurement in this second use case. As Figure 12 shown, the second use case is a use case in which there are multiple combinations each consisting of one sample and one sample, and different reference colors CB and different sample colors CS need to be reset for each combination. Specifically, the color CB21 attached to Sample 2-1 is set in the reference color area 100, and the color CS21 attached to Sample 2-1 is set in the sample color area 110. Then, the color CB22 attached to Sample 2-2 is set in the reference color area 100, and the color CS22 attached to Sample 2-2 is set in the sample color area 110. Then, the color CB23 attached to Sample 2-3 is set in the reference color area 100, and the color CS23 attached to Sample 2-3 is set in the sample color area 110. Then, the color CB24 attached to Sample 2-4 is set in the reference color area 100, and the color CS24 attached to Sample 2-4 is set in the sample color area 110. In such a case, it is convenient for the user to perform color measurements in the order of Sample 2-1, Sample 2-2, Sample 2-2, Sample 2-3, Sample 2-3, Sample 2-4, Sample 2-4 after setting the color CB21 in the reference color area 100 by performing a color measurement on Sample 2-1 and setting the reference color CB to the unlocked state. Use Figures 13 to 15 to explain the reason.

[0070] When the user starts a predetermined application program of the terminal device 60, the display processing unit 19 displays Figure 13 the screen shown in D0 on the display unit 68. In the screen of D0, as shown in D1, it is displayed in a form indicating that the lock button icon 200 is in the unlocked state, and the rest is the same as the screen of C0 in Figure 10 .

[0071] When the user selects the button icon shown in D2, the first color measurement is performed, and the screen shown in D0 changes to the screen shown in D10. Additionally, in the example of the D10 screen, the symbols of the reference color area 100, the sample color area 110, the lock button icon 200, the first button icon 300, and the second button icon 310 are omitted. The same applies to the example of the D20 screen, the example of the D30 screen, and the example of the D40 screen. In the D10 screen, as shown in D11, the color CB21 of the sample 2-1 is set in the reference color area 100. Additionally, as shown in D12, the time information of the color measurement related to the color CB21 is displayed. Additionally, as shown in D13, the second button icon 310 has the same display mode as the first button icon 300. Thus, the user can understand that the second button icon 310 is available. Additionally, the frame icon 400 is displayed in the same color as the color CB21 related to the last color measurement performed.

[0072] Then, when the user selects the button icon shown in D14, the second color measurement is performed, and the screen shown in D10 changes to Figure 14 the D20 screen shown. In the D20 screen, as shown in D21, the color CS21 of the sample 2-1 is set in the sample color area 110. Additionally, as shown in D22, the time information of the color measurement related to the color CS21 is displayed. Additionally, the frame icon 400 is displayed in the same color as the color CS21 related to the last color measurement performed.

[0073] Then, when the user selects the button icon shown in D23, the third color measurement is performed, and the screen shown in D20 changes to the screen shown in D30. In the screen of D30, as shown in D31, the color CB22 of the sample 2-2 is set in the sample color area 110. In addition, as shown in D32, the time information of the color measurement related to the color CB22 is displayed. In addition, as shown in D33, the color CS21 set in the sample color area 110 in the previous color measurement is set in the reference color area 100. That is, in the color measurement system 10 of the present embodiment, when the acquisition unit 15 acquires a new color measurement value, the display processing unit 19 performs a switching display process of setting the sample color CS set in the sample color area 110 as the reference color CB in the reference color area 100 and setting the new color measurement value in the sample color area 110. By setting it in this way, the user can easily understand the change of the color measurement result in the unlocked state. Thus, the color measurement system 10 can provide a user-friendly user interface to the user. In addition, as shown in D34, the display of the time information of the color measurement related to the color CB21 is changed to the display of the time information of the color measurement related to the color CS21. In addition, the frame icon 400 is displayed in the same color as the color CB22 related to the last color measurement performed.

[0074] Then, when the user selects the button icon shown in D35, the fourth color measurement is performed, and the screen shown in D30 changes to Figure 15 the screen shown in D40. In the screen of D40, as shown in D41, the color CS22 of the sample 2-2 is set in the sample color area 110. In addition, as shown in D42, the time information of the color measurement related to the color CS22 is displayed. In addition, as shown in D43, the color CB22 set in the sample color area 110 in the previous color measurement is set in the reference color area 100. In addition, as shown in D44, the display of the time information of the color measurement related to the color CS21 is changed to the display of the time information of the color measurement related to the color CB22. In addition, the frame icon 400 is displayed in the same color as the color CS22 related to the last color measurement performed. Since the screens of the fifth and seventh color measurements after that are the same as those of the third color measurement described above, and the screens of the sixth and eighth color measurements are the same as those of the fourth color measurement described above, the description thereof is omitted.

[0075] As described above, when Figures 10 to 11 the change of the screen example and Figures 13 to 15When comparing the transitions of the screen examples, it can be seen that the above switching display process is implemented when the state of the reference color CB is unlocked, and the switching display process is not implemented when the state of the reference color CB is locked. That is, in the color measurement system 10 of the present embodiment, the display processing unit 19 implements a process of displaying the lock button icon 200 on the display unit 22. The lock button icon 200 is used to set whether the reference color CB of the reference color area 100 is set to the locked state or the unlocked state, and the switching display process is not implemented in the locked state, while the switching display process is implemented in the unlocked state. Thereby, the user can more clearly understand that the state of the reference color CB is the unlocked state. For example, even when the lock button icon 200 is difficult to visually confirm for a predetermined reason, the user can confirm the situation where the switching display process is executed by repeatedly performing color measurement, and thus can recognize the situation where the state of the reference color CB is the unlocked state. Thereby, the color measurement system 10 can provide a user-friendly user interface to the user.

[0076] When the user performs color measurement in the second use case without setting the state of the reference color CB to the unlocked state, since the user sets the reference color area 100 and the sample color area 110 to blank after the second color measurement, it is necessary to perform a process of initializing the application program, resulting in a relatively large workload for the user. In this regard, by the user setting the state of the reference color CB to the unlocked state, the color measurement results of the first, third, fifth, and seventh times are not required, and thus the desired color measurement result can be obtained only by the user performing the operation of alternately measuring the sample and the sample. That is, by displaying the lock button icon 200, the user can efficiently perform the color measurement operation in the second use case, and by combining the lock button icon 200 and the comparison screen, the user can perform color measurement while confirming the unlocked state. Thereby, the color measurement system 10 can provide a user-friendly user interface to the user. Figure 14 As described above, the present embodiment relates to a color measurement system including: an acquisition unit that acquires a color measurement value measured by a color measurement unit; a display processing unit that implements a display process of a comparison graph formed by combining a reference color graph of a reference color area and a sample color graph of a sample color area; and a comparison processing unit that compares the color value of the reference color set in the reference color area with the color value of the sample color set in the sample color area.

[0077] As described above,

[0078] According to the present embodiment, by setting a comparison graph formed by combining the reference color graph in the reference color area and the sample color area, it is possible to clearly grasp the changes in the reference color in the reference color area and the sample color in the sample color area through color measurement and visual observation, and it is possible to obtain a color measurement result of the color difference ΔE between the color value based on the sample color and the color value of the reference color. Thus, the user can perform color measurement corresponding to various use cases. Thus, the color measurement system can provide the user with a user interface corresponding to various use cases in color measurement.

[0079] In addition, it may be set that the display processing unit performs processing of displaying a lock button icon on the display unit, and the lock button icon is used to set whether the reference color in the reference color area is in a locked state or an unlocked state.

[0080] By setting it in this way, the user can arbitrarily switch the state of the reference color between the locked state and the unlocked state on the screen of the display unit.

[0081] In addition, it may be set that when the acquisition unit has acquired a new color measurement value, the display processing unit performs switching display processing, and the switching display processing is to set the sample color set in the sample color area as the reference color in the reference color area, and set the new color measurement value in the sample color area.

[0082] By setting it in this way, the user can easily understand the change of the color measurement result in the unlocked state.

[0083] In addition, it may be set that the display processing unit performs processing of displaying a lock button icon on the display unit, and the lock button icon is used to set whether the reference color in the reference color area is in a locked state or an unlocked state, and the switching display processing is not performed in the locked state, but is performed in the unlocked state.

[0084] By setting it in this way, it is possible to make the user more clearly understand the situation where the state of the reference color is in the unlocked state.

[0085] In addition, it may be set that the display processing unit performs processing of displaying a first button icon for setting the reference color at a position corresponding to the reference color area and a second button icon for setting the sample color at a position corresponding to the sample color area.

[0086] By setting it in this way, the user can easily switch the settings of the reference color and the sample color.

[0087] In addition, it can also be set such that when the reference color is not set in the reference color area and the sample color is not set in the sample color area, the display processing unit performs display processing to make the second button icon unusable.

[0088] By setting it in this way, it is possible to prevent the situation where the user sets the sample color in the sample color area while the reference color is not set in the reference color area.

[0089] In addition, it can also be set such that when the reference color is not set in the reference color area and the sample color is not set in the sample color area, the display processing unit performs display processing to gray out the second button icon.

[0090] By setting it in this way, the user can understand the situation where the second button icon cannot be used.

[0091] In addition, it can also be set such that when the first button icon is selected, the display processing unit performs processing to display the first selection menu screen for selecting the reference color set in the reference color area, and when the second button icon is selected, the display processing unit performs processing on the second selection menu screen for selecting the sample color set in the sample color area.

[0092] By setting it in this way, the user can set the reference color and the sample color in detail.

[0093] In addition, it can also be set such that the display processing unit performs processing to display the color selected based on at least one of the color samples, colorimetric values, color history values, and reference color groups in the first selection menu screen as the reference color, and performs processing to display the color selected based on at least one of the color samples, colorimetric values, and color history values in the second selection menu screen as the sample color.

[0094] By setting it in this way, the user can obtain the reference color and the sample color through various methods.

[0095] In addition, it can also be set such that the display processing unit performs processing to display a frame icon on the display unit, and the frame icon is based on the colorimetric value finally measured by the colorimetric unit and surrounds the comparison graph.

[0096] By setting it in this way, the user can understand the color that was finally colorimetrically measured.
