[0010] The present embodiment will be described below. Note that the present embodiment described below does not unduly limit the content of the claims. Furthermore, not all of the configurations described in the present embodiment are necessarily essential components.

[0011] 1. Terminal device Fig. 1 shows an example of the configuration of a terminal device 10 according to this embodiment. Fig. 1 also shows an example of the configuration of a colorimeter 60. The terminal device 10 includes a communication unit 30, a terminal display unit 40, and a processing unit 20. The terminal device 10 is a device separate from the colorimeter 60. The terminal device 10 may be, for example, a smart device such as a smartphone or a tablet terminal, a wearable terminal such as a smart watch or smart glasses, or a personal computer.

[0012] The communication unit 30 performs wired or wireless communication with an external device such as the colorimeter 60. Specifically, the processing unit 20 performs communication control processing such as information transmission processing and information reception processing on the communication unit 30, causing the communication unit 30 to transmit information to the colorimeter 60 or receive information from the colorimeter 60. The communication unit 30 can be realized by, for example, a communication integrated circuit (IC) such as a communication ASIC or a communication processor, communication firmware, or the like.

[0013] The terminal display unit 40 displays various types of information. For example, the terminal device 10 can display information received from the colorimeter 60 on the terminal display unit 40. The terminal display unit 40 also serves as an operation interface for inputting user operation information. The terminal display unit 40 is, for example, a touch panel, and the user can perform various operations by touching the terminal display unit 40, which is a touch panel. The terminal display unit 40 can be realized by various types of displays, such as a liquid crystal display or an organic EL display that employs a touch panel system.

[0014] The storage unit 50 stores various types of information such as programs and data. The storage unit 50 functions as a work area for the processing unit 20 and the communication unit 30. The storage unit 50 can be realized by, for example, a semiconductor memory such as an SRAM (Static Random Access Memory), a DRAM (Dynamic Random Access Memory), or a flash memory, a register, a hard disk drive, or a combination of these.

[0015] The processing unit 20 performs control processing of the terminal device 10. The processing unit 20 performs various control processing related to the operation of the terminal device 10, such as control of the communication state of the communication unit 30 and control related to the display on the terminal display unit 40. The processing unit 20 can be realized by, for example, a logic circuit generated by an automatic placement and routing method such as a gate array, or various processors such as a microcomputer.

[0016] The colorimeter 60 performs color measurement and includes a colorimeter communication unit 80, a colorimeter unit 100, a colorimeter display unit 90, and a colorimeter processing unit .

[0017] The colorimetric unit 100 measures the color of a measurement target such as a printed material, and outputs colorimetric values ​​that are the colorimetric results. The colorimetric unit 100 can be realized by a colorimetric sensor such as a spectroscopic sensor or an image sensor.

[0018] The colorimeter display unit 90 displays various information to the user. Specifically, the colorimeter display unit 90 displays colors based on information about the colors measured by the colorimeter unit 100, and displays information necessary for the user to operate the colorimeter 60 and various status information about the colorimeter 60. The colorimeter display unit 90 can be realized by various displays, such as a liquid crystal display or an organic EL display.

[0019] The colorimeter processing unit 70 performs control processing for the colorimeter 60. For example, this includes various control processing related to the operation of the colorimeter 60, such as control processing for the colorimeter communication unit 80, control of the colorimeter unit 100, and control related to the display on the colorimeter display unit 90. The colorimeter processing unit 70 can be realized by a processor that operates based on information such as a program, and a memory that stores information such as the program.

[0020] The colorimeter communication unit 80 performs wired or wireless communication with an external device such as the terminal device 10. The colorimeter communication unit 80 can be realized by, for example, a communication integrated circuit (IC) such as a communication ASIC or a communication processor, or communication firmware. In this embodiment, the colorimeter processing unit 70 performs communication control processing, such as information transmission processing and information reception processing, on the colorimeter communication unit 80, so that the colorimeter communication unit 80 transmits information to an external device such as the terminal device 10 and receives information from the device. The colorimeter communication unit 80 can be realized by a communication integrated circuit (IC) or the like, similar to the communication unit 30 of the terminal device 10.

[0021] FIG. 2 is a diagram showing the top surface of the colorimeter 60 on which the operation panel is provided. As shown in FIG. 2, the colorimeter 60 is provided with, for example, a colorimeter button 61, a cross key 62, a back key 63, a power button 64, and a colorimeter display unit 90. Note that FIG. 2 shows a case where an example of a colorimeter result is displayed on the colorimeter display unit 90. The colorimeter button 61 is an operation device that allows the user to instruct the colorimeter 60 to perform colorimeter measurement. For example, when the user presses the colorimeter button 61, colorimeter unit 100 performs colorimeter measurement. The cross key 62 is an operation device that allows the user to instruct directions such as up, down, left, and right.

[0022] In FIG. 2, the colorimeter display 90 displays status information such as the time and remaining battery level at the top. Below this status information, in area A1, the measured color information is displayed in the L*a*b* color system. In the L*a*b* color system, L is a numerical parameter indicating brightness. L ranges from 0 to 100, with larger values ​​indicating brighter colors. Furthermore, a and b represent color shades, with a being a parameter indicating the change from red to green, and b being a parameter indicating the change from blue to yellow. The more positive a is, the more red the color becomes; the more negative a is, the more green the color becomes; the more positive b is, the more yellow the color becomes; and the more negative a is, the more blue the color becomes. When both a and b are zero, the color is achromatic. ΔE, displayed below L, a, and b, is a parameter indicating the color difference between the measured color and the color of the reference color patch.

[0023] 2, the measured color is displayed in a shaded area A2 surrounding an area A1 in which the numerical parameters L, a, and b are displayed on the colorimeter display unit 90. This allows the user to visually grasp the measured color along with the numerical information about the colorimetric results.

[0024] FIG. 3 shows an example of a screen displayed on the terminal display unit 40 of the terminal device 10 of this embodiment. Specifically, this is an example of a screen displayed on the terminal display unit 40 when the terminal device 10 communicates with the colorimeter 60 and receives color measurement result information from the colorimeter 60. Status information such as the time and remaining battery level is displayed at the top of the screen. Below that, information about the colorimeter 60, the device with which the terminal device 10 is communicating, is displayed, indicating that the terminal device 10 is in communication with the colorimeter 60. In area B1 below that, information about the color measured by the colorimeter 60 is also displayed on the terminal display unit 40 of the terminal device 10. The values ​​of the numerical parameters L, a, and b of the measured color are displayed to the right of area B1. The measured color is also displayed in area B2, which is surrounded by diagonal lines. This allows the user to visually grasp the color measurement results in addition to the values ​​of the numerical parameters L, a, and b. In addition, area B3 below that displays, for example, the three most recent color measurement results along with the date and time of color measurement as the measurement history of the colorimeter 60. Area B4 at the bottom of the screen displays, from left to right, an icon corresponding to the color measurement button, an icon corresponding to the button for comparing the color measurement results with a color patch, an icon corresponding to the button for displaying the color measurement result history, and an icon corresponding to the button for displaying library information. These icons are images that enable some of the operations performed on the colorimeter 60 to be performed on the screen of the terminal device 10.

[0025] FIG. 4 shows a situation in which a user performs a color measurement test using the colorimeter 60 and the terminal device 10. In FIG. 4, the user uses the colorimeter 60 to measure the color of an object placed opposite the bottom surface of the colorimeter 60. The object is a product or color chart whose color is to be measured. First, the user places the colorimeter 60 on the color to be measured among the colors on the object and presses the color measurement button 61 on the colorimeter 60. Then, the colorimeter unit 100 located below the colorimeter 60 measures information about the color on the object, and the color measurement results are displayed on the colorimeter display unit 90. While performing the above operations on the colorimeter 60, the user can simultaneously check the color measurement results measured by the colorimeter 60 on the terminal display unit 40 of the terminal device 10, which is in communication with the colorimeter 60. In this case, the user operates the colorimeter 60 with his right hand and holds the terminal device 10 with his left hand. Therefore, when a user measures the color of an object to be measured using the colorimeter 60 and the terminal device 10, the distance D between the colorimeter 60 and the terminal device 10 is usually about several tens of centimeters.

[0026] Next, we will explain the problems that arise when a user performs color measurement using a terminal device 10 in conjunction with a colorimeter 60. In the process of inspecting the color of an object to be measured, a color group containing multiple color patches is typically provided, and color measurement is performed on each color patch belonging to the color group in a predetermined order. If the color being inspected matches a predetermined color, it is determined to be normal. If it does not, it is determined to be abnormal. Therefore, it is necessary to thoroughly inspect each color patch belonging to a color group and reliably detect colors that do not meet predetermined color standards to maintain product quality. Patent Document 1 (JP-A-2005-102626) discloses an inspection method that uses a terminal device 10 in conjunction with a colorimeter 60 to meet such needs. According to this method, the terminal device 10 compares a predetermined color patch with a color measured by the colorimeter 60. If the color difference between the measured color and the corresponding color patch meets the standard, it is determined to be normal. On the other hand, if the color difference between the measured color and the corresponding color patch does not meet the standard, it is determined to be abnormal. If an abnormality is determined, a warning message is displayed by flashing on the portion of the color patch determined to be abnormal in the color group displayed on the terminal display unit 40 of the terminal device 10, thereby reliably detecting that the measured color does not meet the specified quality. Furthermore, when applying the inspection method of Patent Document 1, the color measurement results can be displayed on the colorimeter display unit 90 of the colorimeter 60 as well as on the terminal display unit 40. In this case, the measured color may be displayed in different colors on the terminal display unit 40 and the colorimeter display unit 90. For example, the display device used for the colorimeter display unit 90 and the display device used for the terminal display unit 40 often have different color resolutions and color reproducibility, which can lead to such color differences. If such color differences occur, the user may confuse the color being measured with the color of another color patch belonging to the color group, which may lead to incorrect color measurement operation of the colorimeter 60.

[0027] In this regard, the terminal device 10 of this embodiment shown in FIG. 1 includes a communication unit 30 that communicates with a colorimeter 60 including a colorimeter display unit 90, and a processing unit 20 that performs display processing on the terminal display unit 40. The processing unit 20 can perform processing to determine whether to display the color of the colorimeter 60's color measurement result on both the colorimeter display unit 90 and the terminal display unit 40, or to display it on the terminal display unit 40, based on the distance from the colorimeter 60. That is, when the distance D between the terminal device 10 and the colorimeter 60 is short and the user can see the displays of both the terminal device 10 and the colorimeter 60, the processing unit 20 displays the color of the colorimeter result on the terminal display unit 40, but not on the colorimeter display unit 90. On the other hand, when the distance D between the terminal device 10 and the colorimeter 60 is far, the processing unit 20 performs processing to determine whether to display the color of the colorimeter result on both the terminal display unit 40 and the colorimeter display unit 90. In this manner, when the user can see the displays of both the terminal device 10 and the colorimeter 60, the user can perform color measurement by looking only at the colors displayed on the terminal display 40, which has excellent color reproducibility, and can avoid confusing colors by looking at multiple displays with different color reproducibility. On the other hand, when the distance D between the terminal device 10 and the colorimeter 60 is large, the measured colors are displayed on both the colorimeter display 90 and the terminal display 40, so the user can perform color measurement using the colorimeter 60 while looking at the colorimeter display 90. In this case, because the user cannot see the terminal display 40, there is no risk of confusing colors even if the measured colors are displayed in different colors on both the colorimeter display 90 and the terminal display 40. In other words, performing color measurement using the terminal device 10 of this embodiment makes it possible to avoid confusing color patches within a color group and resulting erroneous color measurement operations using the colorimeter 60.

[0028] Furthermore, a predetermined distance Dt can be set as a criterion in the above-described process for determining the display state selection. The predetermined distance Dt is the distance D at which the user is expected to be able to perform color measurement while viewing both the colorimeter display unit 90 and the terminal display unit 40. That is, as described above, the predetermined distance Dt is expected to be approximately several tens of centimeters. For example, when the distance D is equal to or less than the predetermined distance Dt, the user can operate the colorimeter 60 with one hand, as described in FIG. 4, and simultaneously view the colorimeter display unit 90 of the colorimeter 60 while viewing the terminal display unit 40 of the terminal device 10 held with the other hand. In this case, by displaying the color measurement results only on the terminal display unit 40, rather than on the colorimeter display unit 90, the user can avoid confusing color patches within a color group and resulting erroneous color measurement operation of the colorimeter 60. However, when the distance D is greater than the predetermined distance Dt, the user cannot view the terminal display unit 40 of the terminal device 10 while operating the colorimeter 60. That is, the user is not in a state where he or she is operating the colorimeter 60 with one hand while holding the terminal device 10 with the other hand, as described in FIG. 4 . Therefore, the user cannot see the terminal display unit 40 of the terminal device 10. Therefore, in this case, even if the color of the color measurement result is displayed on both the colorimeter display unit 90 and the terminal display unit 40, the user will not confuse color patches within a color group. Therefore, if the distance D is greater than the predetermined distance Dt, it may be determined that the color of the color measurement result is displayed on both the colorimeter display unit 90 and the terminal display unit 40.

[0029] FIG. 5 is a flowchart illustrating an example of processing performed by the terminal device 10 of this embodiment. First, in step S1, the processing unit 20 of the terminal device 10 determines whether the distance D is equal to or less than a predetermined distance Dt. Specifically, the processing unit 20 determines whether the distance D between the terminal device 10 and the colorimeter 60 is equal to or less than the predetermined distance Dt (step S1). If it is determined in step S1 that the distance D is equal to or less than the predetermined distance Dt (YES), the processing unit 20 of the terminal device 10 determines to display the color of the colorimeter result on the terminal display unit 40, not on the colorimeter display unit 90 (step S2). On the other hand, if it is determined in step S1 that the distance D is greater than the predetermined distance Dt (NO), the processing unit 20 of the terminal device 10 determines to display the color of the colorimeter result on both the colorimeter display unit 90 and the terminal display unit 40 (step S3). After steps S2 and S3, the processing is repeated again, starting from step S1.

[0030] That is, when the distance D between the colorimeter 60 and the terminal device 10 is equal to or less than the predetermined distance Dt, the processing unit 20 can display the color of the colorimeter result on the terminal display unit 40 without displaying it on the colorimeter display unit 90. Furthermore, when the distance D between the colorimeter 60 and the terminal device 10 is greater than the predetermined distance Dt, the processing unit 20 can determine that the color of the colorimeter result should be displayed on both the colorimeter display unit 90 and the terminal display unit 40. This eliminates the need for unnecessary control processing, such as not displaying the color of the colorimeter result on the colorimeter display unit 90, even when there is no risk of the user mixing up color patches within a color group or performing an incorrect color measurement operation on the colorimeter 60. That is, it is possible to accurately identify cases where there is a risk of the user mixing up color patches and then perform control processing to not display the color of the colorimeter result on the colorimeter display unit 90.

[0031] The terminal device 10 of this embodiment can also be realized as a program. That is, the program of this embodiment causes a computer to function as a communication unit 30 that communicates with a colorimeter 60 including a colorimeter display unit 90, and a processing unit 20 that performs display processing on the terminal display unit 40. The processing unit 20 can determine, based on the distance D from the colorimeter 60, whether to display the color of the color measurement result of the colorimeter 60 on both the colorimeter display unit 90 and the terminal display unit 40, or to display it on the terminal display unit 40. Here, the computer can be a smartphone, a tablet terminal, a wearable terminal such as a smartwatch, a network terminal such as a personal computer, or the like. In this way, the same effects as those described above can be achieved.

[0032] The terminal device 10 of this embodiment can also be realized as a processing method. That is, the processing method of this embodiment can perform communication with the colorimeter 60 including the colorimeter display unit 90, display processing on the terminal display unit 40, and processing to determine whether the color of the color measurement result of the colorimeter 60 should be displayed on both the colorimeter display unit 90 and the terminal display unit 40, or on the terminal display unit 40, based on the distance D from the colorimeter 60. In this way, it is possible to obtain the same effect as above.

[0033] 2. Detailed processing example Next, a detailed processing example of this embodiment will be described. In the terminal device 10 of this embodiment, the result of the determination process can be transmitted to the colorimeter 60 via the communication unit 30 of the terminal device 10. For example, when the distance D between the terminal device 10 and the colorimeter 60 is equal to or less than a predetermined distance Dt, the colorimeter 60 is instructed to prohibit display of the colorimeter result on the colorimeter display unit 90 so that the colorimeter result is not displayed on the colorimeter display unit 90 but on the terminal display unit 40. On the other hand, when the distance D is greater than the predetermined distance Dt, the colorimeter 60 is instructed to permit display of the colorimeter result on the colorimeter display unit 90 so that the colorimeter result is displayed on both the colorimeter display unit 90 and the terminal display unit 40. In this way, depending on the distance D, instruction information permitting or prohibiting display on the colorimeter display unit 90 can be transmitted to the colorimeter 60. Furthermore, the instruction information can be transmitted to the colorimeter 60 via the communication unit 30 of the terminal device 10.

[0034] That is, the processing unit 20 of the terminal device 10 of this embodiment determines whether to display the color measurement results of the colorimeter 60 on both the colorimeter display unit 90 and the terminal display unit 40, or to display the color measurement results on the terminal display unit 40, based on the distance D between the terminal device 10 and the colorimeter 60. Then, based on the result of this determination, the processing unit 20 performs processing to transmit instruction information to the colorimeter 60 via the communication unit 30, indicating whether to permit or prohibit display of the color measurement results on the colorimeter display unit 90. By transmitting such instruction information, the colorimeter 60 can determine whether display is permitted or prohibited based on the instruction information and change the display state. For example, if the distance D between the terminal device 10 and the colorimeter 60 is short and the user can see both the colorimeter display unit 90 and the terminal display unit 40, as described above, it is necessary not to display the color measurement results on the terminal display unit 40 to prevent the user from confusing color patches within a color group. In this case, instruction information prohibiting the display of the colorimeter 60 is sent from the terminal device 10 to the colorimeter 60, so the colorimeter 60 can prevent the colorimeter 60 from displaying the colorimeter results on the colorimeter display unit 90 based on the instruction information. On the other hand, if the distance D is far and the user can only see the colorimeter display unit 90, as described above, even if the colorimeter results are displayed on the terminal display unit 40, there is no risk that the user will confuse color patches within a color group. In this case, instruction information permitting the display of the colorimeter results on the colorimeter display unit 90 is sent from the terminal device 10 to the colorimeter 60, so the colorimeter 60 can display the colorimeter results on the colorimeter display unit 90 based on the instruction information.

[0035] Furthermore, as described above, the processing unit 20 of the terminal device 10 performs a determination process based on the distance D between the terminal device 10 and the colorimeter 60 as to whether to display the color of the colorimeter result on both the colorimeter display unit 90 and the terminal display unit 40, or to display it on the terminal display unit 40. The determination result is then transmitted as instruction information from the communication unit 30 of the terminal device 10 to the colorimeter 60. Specifically, the instruction information is transmitted from the communication unit 30 of the terminal device 10 to the colorimeter communication unit 80 of the colorimeter 60. Then, based on the instruction information, the display state of the colorimeter display unit 90 is changed under the control of the colorimeter processing unit 70.

[0036] Now, in order to determine whether to display the color measurement results of the colorimeter 60 on both the colorimeter display unit 90 and the terminal display unit 40, or to display the color on the terminal display unit 40, it is desirable for the processing unit 20 to constantly grasp the distance D between the terminal device 10 and the colorimeter 60. This is because the determination of whether the distance D is equal to or less than a predetermined distance Dt changes dynamically depending on the state of use of the colorimeter 60 and the terminal device 10 by the user. Here, a distance determination method based on the received signal strength of a beacon signal can be used as a method for constantly grasping the distance D. The determination method will be described below.

[0037] It is generally known that when the distance between a device transmitting a wireless signal and a device receiving the wireless signal is d, the received signal strength indication (RSSI) of the wireless signal received by the device at distance d weakens in inverse proportion to the square of the distance d. Therefore, if the received signal strength RSSI at a position a reference distance away from the transmitting device is a reference signal strength value SIs, the distance d can be expressed by equation (1).

number

[0038] For example, if the reference distance is 1 meter, the reference signal strength value SIs is 4, and the measured received signal strength RSSI is 1, then the distance d is 2 meters. In this way, the distance d between the transmitting device and the receiving device can be calculated based on the reference signal strength value SIs and the received signal strength RSSI.

[0039] Distance determination using such a wireless signal can be achieved by transmitting and receiving a beacon signal containing information such as the reference signal strength value SIs described above between a transmitting device and a receiving device. FIG. 6 shows an example of the data structure of a beacon signal. As shown in FIG. 6, the beacon signal contains information such as a source address, identification information of the terminal device, a reference signal strength value, and a user's device usage history. The source address is address information indicating the source of the beacon signal, such as a Bluetooth (Bluetooth is a registered trademark) device address such as Bluetooth Low Energy (BLE). The device identification information is information that uniquely identifies the source device, such as a MAC address. As described above, the reference signal strength value SIs is the received signal strength (RSSI) value received by the receiving device at a reference distance from the transmitting device, and is information used to estimate the distance between devices communicating wirelessly. Note that the beacon signal may include data not included in the example data structure of FIG. 6, or conversely, some of the data in FIG. 6 may not be included.

[0040] 7 shows an example of the dependency of the signal strength SI received by the terminal device 10 on the distance D based on the above explanation. That is, the signal strength SI is expressed by equation (2).

number

[0041] Because the signal strength SI is inversely proportional to the square of the distance D, it decreases sharply as the distance D increases at short distances and decreases more gradually as the distance D increases. Therefore, to calculate the distance D from the signal strength SI using a distance determination method based on the received signal strength of a beacon signal, the storage unit 50 of the terminal device 10 stores information on a relational expression equivalent to Equation (2) and a reference signal strength value SIs, and the distance D can be calculated by substituting the measured signal strength SI. Alternatively, the information on Equation (2) may be stored in the storage unit 50 as a lookup table, and the distance D may be calculated by retrieving appropriate data from the lookup table based on the reference signal strength value SIs and the measured signal strength SI. The processing unit 20 compares the distance D calculated in this manner with a predetermined distance Dt and determines whether or not to display the color of the color measurement result on the colorimeter display unit 90.

[0042] FIG. 8 is a flowchart illustrating a processing example in which the above-described distance determination method based on the received signal strength of a beacon signal is applied to the processing example described in FIG. 8 . Specifically, in the processing example of FIG. 8 , the communication unit 30 communicates with the colorimeter 60 via wireless communication, and the processing unit 20 determines the distance D between the terminal device 10 and the colorimeter 60 based on the signal strength SI of the wireless communication. First, in step S11, the terminal device 10 determines whether it is communicating with the colorimeter 60 via wireless communication. Specifically, the processing unit 20 of the terminal device 10 determines whether it is communicating with the colorimeter 60 via wireless communication (step S11). Specifically, the processing unit 20 determines whether wireless communication between the communication unit 30 and the colorimeter communication unit 80 is established. Next, if it is determined in step S11 that wireless communication is being performed (YES), the processing unit 20 calculates the distance D based on the signal strength SI and determines whether the distance D is equal to or less than a predetermined distance Dt (step S12). If it is determined in step S12 that the distance D is equal to or less than the predetermined distance Dt (YES), the processing unit 20 determines to display the color of the color measurement result not on the colorimeter display unit 90 but on the terminal display unit 40 (step S13). On the other hand, if it is determined in step S11 by the processing unit 20 that the communication unit 30 is not communicating with the colorimeter 60 via wireless communication (NO), or if it is determined in step S12 by the processing unit 20 that the distance D is greater than the predetermined distance Dt (NO), the processing unit 20 determines to display the color of the color measurement result on both the colorimeter display unit 90 and the terminal display unit 40 (step S14). After steps S13 and S14, the processing is repeated again in order from step S11.

[0043] In this way, the processing unit 20 of the terminal device 10 can calculate the distance D between the colorimeter 60 and the terminal device 10 based on the signal strength SI of the wireless signal. Therefore, even if the distance D between the terminal device 10 and the colorimeter 60 changes dynamically depending on the user's work state, it is possible to constantly grasp the distance D. Therefore, it is possible to select a display state suitable for the user's work state without delay.

[0044] In the case of FIG. 8, the distance D may be calculated using the averaged signal strength SI. As explained in FIG. 7, the dependency of the signal strength SI on the distance D is inversely proportional to the square of the distance D. However, in reality, interference between wireless signals occurs, so the greater the distance between devices, the greater the deviation from equation (1). For this reason, by measuring the signal strength SI multiple times and calculating the distance D using the average value, the deviation from equation (1) due to interference between wireless signals can be reduced. FIG. 9 shows a flowchart of a processing example in this case. The difference from FIG. 8 is that, if communication is performed via wireless communication (YES) in step S11 of FIG. 8, step S22 is added in FIG. 9, which calculates the average value of the signal strength SI for N measurements. Also, in step S23 of FIG. 9, which corresponds to step S12 of FIG. 8, a determination is made as to whether the averaged signal strength SI, rather than the signal strength SI, is equal to or greater than a predetermined strength SIt.

[0045] Here, as a method for averaging the signal strength SI, for example, the method shown in the flowchart of FIG. 10 can be used. First, after the processing unit 20 detects that the user has pressed the colorimetric button 61 (step S31), the colorimeter 60 measures the signal strength SI a predetermined number of times (step S32). In FIG. 10, the predetermined number of times is described as N times, where N is an integer equal to or greater than 2. Then, the processing unit 20 performs averaging processing on the N pieces of signal strength SI data to calculate the average value of the signal strength SI (step S33). That is, in the averaging method shown in FIG. 10, the processing unit 20 does not always measure the signal strength SI of the wireless signal, but measures the signal strength SI when it detects that the user has pressed the colorimetric button 61 of the colorimeter 60.

[0046] On the other hand, the averaging process method shown in FIG. 11 is based on the assumption that the terminal device 10 periodically measures the signal strength SI of a wireless signal. First, as in the case of FIG. 10, the processing unit 20 detects that the user has pressed the colorimeter button 61 of the colorimeter 60 (step S41). Next, in the method of FIG. 11, the processing unit 20 calculates the average value of the most recent N signal strengths SI (step S42). That is, the processing unit 20 references the signal strength SI data for the N measurements made up until the time the processing unit 20 detected that the colorimeter button 61 was pressed, and performs averaging of the data. Here, the averaging process method shown in FIG. 10 has the advantage that the processing unit 20 does not periodically measure the signal strength SI in the background, thereby reducing the burden on the control process of the processing unit 20. On the other hand, in the averaging process method shown in FIG. 10, the processing unit 20 measures the signal strength SI for N measurements after detecting that the colorimeter button 61 has been pressed, and then performs averaging. Therefore, there is a disadvantage in that there is a time lag between when the user presses the colorimetric measurement button 61 and when instruction information for permitting or prohibiting display of the color measurement result on the colorimetric device display unit 90 is sent to the colorimetric device 60. In contrast, the averaging method shown in FIG. 11 has a disadvantage in that the processing unit 20 periodically measures the signal strength SI in the background, which increases the burden on the control processing of the processing unit 20. However, because the processing unit 20 periodically measures the signal strength SI in the background, the time lag between when the user presses the colorimetric measurement button and when instruction information for permitting or prohibiting display of the color measurement result on the colorimetric device display unit 90 is sent to the colorimetric device 60 is reduced, allowing the user to select a display state appropriate for their work status without delay. The averaging process may be performed using any of the arithmetic mean, geometric mean, harmonic mean, etc. Furthermore, instead of the averaged signal strength SI, the median of N signal strength SI data may be used. That is, in the terminal device 10 of this embodiment, the processing unit 20 averages the signal strength SI to determine the distance D from the colorimetric device 60. In this way, when calculating the distance D based on the signal strength SI, it is possible to reduce problems such as errors caused by interference between wireless signals, and it is possible to reliably achieve a display state that is appropriate for the user's work state.

[0047] In the processing examples of FIGS. 8 and 9, whether the distance D is equal to or greater than the predetermined distance Dt can also be determined by checking whether the magnitude of the signal intensity SI is equal to or greater than the predetermined intensity SIt. That is, if the measured signal intensity SI or the averaged signal intensity SI is equal to or greater than the predetermined intensity SIt, the processing unit 20 can determine that the distance D is equal to or less than the predetermined distance Dt. In this case, the processing unit 20 can determine to display the color of the color measurement result on the terminal display unit 40 without displaying it on the colorimeter display unit 90. Conversely, if the measured signal intensity SI or the averaged signal intensity SI is less than the predetermined intensity SIt, the processing unit 20 can determine that the distance D is greater than the predetermined distance Dt. In this case, the processing unit 20 can determine to display the color of the color measurement result on both the colorimeter display unit 90 and the terminal display unit 40. FIG. 12 shows a flowchart of a processing example in this case. The difference from FIGS. 8 and 9 is step S54, which corresponds to step S12 in FIG. 8 and step S23 in FIG. 9. In step S54 of FIG. 12 , the processing unit 20 does not determine whether the distance D is equal to or less than the predetermined distance Dt. Instead, it determines whether to proceed to step S55 or step S56 depending on whether the signal intensity SI or the averaged signal intensity SI is equal to or greater than the predetermined intensity SIt. The above determination process can be realized by storing the signal intensity SI when the distance D between the terminal device 10 and the colorimeter 60 is equal to the predetermined distance Dt as the predetermined intensity SIt in, for example, the storage unit 50 of the terminal device 10, and then having the processing unit 20 compare the measured signal intensity SI with the predetermined intensity SIt. This determination process allows the processing unit 20 to determine whether to permit or prohibit the display of the color measurement result on the colorimeter display unit 90 by directly comparing the signal intensity SI with the predetermined intensity SIt, without calculating the distance D based on the signal intensity SI and comparing the distance D with the predetermined distance Dt. This simplifies and speeds up the control process in the processing unit 20.

[0048] 5, 8, 9, and 12, each process may be started when it is detected that the user has pressed the color measurement button 61 of the colorimeter 60. That is, in the terminal device 10 of this embodiment, the processing unit 20 can perform a process of determining whether to display the color of the color measurement result of the colorimeter 60 on both the colorimeter display unit 90 and the terminal display unit 40, or to display it on the terminal display unit 40, based on the distance D between the terminal device 10 and the colorimeter 60 when the instruction operation for color measurement by the colorimeter 60 is performed.

[0049] In this way, when the user issues an instruction to perform colorimetry, the processing unit 20 of the terminal device 10 performs the above-described determination process of whether or not to display the color of the colorimetry result on the colorimeter display unit 90. Therefore, when the user does not issue an instruction to perform colorimetry, the above-described determination process does not need to be performed, and the load on the control process of the processing unit 20 can be reduced.

[0050] As mentioned above, when the color measurement results are displayed on both the terminal display unit 40 of the terminal device 10 and the colorimeter display unit 90 of the colorimeter 60, there is a risk that the user may confuse the color being measured with the color of another color patch due to differences in the color reproducibility of the terminal display unit 40 and the colorimeter display unit 90.

[0051] In this regard, the colorimeter 60 of this embodiment includes a colorimeter unit 100 that performs color measurement, a colorimeter communication unit 80 that communicates with the terminal device 10, a colorimeter display unit 90, and a colorimeter processing unit 70 that performs display processing on the colorimeter display unit 90, and the colorimeter processing unit 70 performs processing to display the colors of the colorimeter result by the colorimeter unit 100 on the colorimeter display unit 90 when communication with the terminal device 10 via the colorimeter communication unit 80 is not established, and when communication with the terminal device 10 via the colorimeter communication unit 80 is established, determines whether to display the colors of the colorimeter result on the colorimeter display unit 90 based on instruction information from the terminal device 10 to prohibit or allow display. Here, the colorimeter communication unit 80, the colorimeter display unit 90, the colorimeter processing unit 70, and the colorimeter unit 100 are as described in FIG. 1. In the colorimeter 60 of this embodiment, the colorimeter processing unit 70 of the colorimeter 60 first determines whether communication has been established between the colorimeter communication unit 80 and the communication unit 30 of the terminal device 10. If communication has not been established, the colorimeter 60 cannot transmit the colorimeter results to the terminal device 10. Therefore, the colorimeter results are not transmitted from the colorimeter 60 to the terminal device 10, and the colorimeter processing unit 70 of the colorimeter 60 executes processing to display the colorimeter results on the colorimeter display unit 90. In other words, if communication has not been established between the colorimeter 60 and the terminal device 10, the colorimeter results are displayed only on the colorimeter display unit 90. Here, when communication is not established between the colorimeter communication unit 80 and the terminal device 10, the distance D between the colorimeter 60 and the terminal device 10 is large, and the user can see the colorimeter display unit 90 of the colorimeter 60 but cannot see the terminal display unit 40 of the terminal device 10. Therefore, no inconvenience occurs even if the colorimeter results are not displayed on the terminal display unit 40 of the terminal device 10. On the other hand, when communication is established, the colorimeter processing unit 70 of the colorimeter 60 determines whether to display the colors of the colorimeter results on the colorimeter display unit 90 based on instruction information from the terminal device 10 to prohibit or permit display. In this case, as described above, the terminal device 10 transmits instruction information to prohibit display when the distance D is close, and transmits information to permit display when the distance D is far. First, the colorimeter 60 receives the instruction information, and if the instruction information prohibits display, does not display the colorimeter results on the colorimeter display unit 90.Specifically, the colorimeter communication unit 80 of the colorimeter 60 receives the instruction information, and based on the instruction information, the colorimeter processing unit 70 performs control processing to prevent the colorimeter results from being displayed on the colorimeter display unit 90. Therefore, when the distance D between the colorimeter 60 and the terminal device 10 is short, the colorimeter results are displayed only on the terminal display unit 40 of the terminal device 10, which has excellent color reproducibility. Therefore, by displaying the colorimeter results in different colors on both the colorimeter display unit 90 and the terminal display unit 40, it is possible to prevent the user from confusing the color being measured with the color of another color patch. Furthermore, when the instruction information permits display, the colorimeter communication unit 80 of the colorimeter 60 displays the colorimeter results on the colorimeter display unit 90. Specifically, the colorimeter communication unit 80 of the colorimeter 60 receives the instruction information, and based on the instruction information, the colorimeter processing unit 70 performs control processing to display the colorimeter results on the colorimeter display unit 90. Therefore, when the distance D between the colorimeter 60 and the terminal device 10 is large, the color measurement results are displayed on both the colorimeter display 90 of the colorimeter 60 and the terminal display 40 of the terminal device 10. In this case, because the distance D is large, the user is performing color measurement by looking only at the colorimeter display 90 of the colorimeter 60, and can perform color measurement by looking at the color measurement results displayed on the colorimeter display 90. In this way, an appropriate display state of the color measurement results can be selected depending on the distance D between the colorimeter 60 and the terminal device 10. Therefore, the color to be measured is displayed in different colors on both the terminal device 10 and the colorimeter 60, which prevents the user from confusing the color to be measured with the color of another color patch and resulting in erroneous color measurement operation of the colorimeter 60.

[0052] Furthermore, in the colorimeter 60 of this embodiment, the measured color can also be displayed in area A2 of the colorimeter display unit 90, as described with reference to FIG. 2 . That is, the measured color can be displayed on the colorimeter display unit 90 so as to surround area A1, in which information on the colorimeter result, such as L, a, and b, is displayed. The colorimeter display unit 90 of the colorimeter 60 often has a smaller display area than the terminal display unit 40 of the terminal device 10. Therefore, the colorimeter display unit 90 may not have enough space to display the numerical parameters, such as L, a, and b, of the measured color and the measured color separately. Therefore, this embodiment makes it possible to effectively use the limited display area of ​​the colorimeter display unit 90 to provide the user with more information. Furthermore, as a result, the user can visually grasp the color of the colorimeter result together with the numerical parameter information, which helps prevent the user from mistaking the color of the measurement target for the color of another color patch or from erroneously operating the colorimeter 60.

[0053] As described above, the terminal device of this embodiment includes a communication unit that communicates with a colorimeter including a colorimeter display unit, and a processing unit that performs display processing on the terminal display unit, and the processing unit is related to the terminal device that performs processing to determine whether the color of the colorimeter's color measurement results should be displayed on both the colorimeter display unit and the terminal display unit, or on the terminal display unit, based on the distance from the colorimeter.

[0054] According to this embodiment, if the user can see the display units of both the terminal device and the colorimeter, the user can measure the color by looking only at the color displayed on the terminal display unit, which has excellent color reproducibility. Therefore, by displaying the color to be measured in different colors on multiple display units, it is possible to prevent the user from confusing the color to be measured with the color of another color patch in the color group and resulting in erroneous color measurement operation of the colorimeter.

[0055] In addition, in the terminal device of this embodiment, when the distance to the colorimeter is less than a predetermined distance, the processing unit may determine to display the color of the color measurement result on the terminal display unit instead of on the colorimeter display unit.

[0056] In this way, there is no need to perform unnecessary control processing such as not displaying the color of the color measurement result on the colorimeter display unit, even in cases where there is no risk of the user mistaking the color being measured or performing an incorrect color measurement operation on the colorimeter.

[0057] In addition, in the terminal device of this embodiment, when the distance to the colorimeter is greater than a predetermined distance, it may be determined that the color of the color measurement result is to be displayed on both the colorimeter display unit and the terminal display unit.

[0058] In this way, when the colorimeter and the terminal device are far apart and it is necessary to display the color of the colorimeter result on both the colorimeter display unit and the terminal display unit, the color of the colorimeter result will be displayed on both displays, thereby avoiding a situation where the colorimeter result cannot be confirmed on the colorimeter display unit.

[0059] In addition, in the terminal device of this embodiment, the processing unit may perform a process of sending instruction information to the colorimeter via the communication unit to allow or prohibit the display of the color of the colorimeter result on the colorimeter display unit based on the result of the judgment process.

[0060] In this way, the colorimeter can determine whether or not to display the color measurement results on the colorimeter display unit based on the instruction information transmitted from the terminal device.

[0061] In the terminal device of this embodiment, the communication unit may communicate with the colorimeter by wireless communication, and the processing unit may determine the distance to the colorimeter based on the signal strength of the wireless communication.

[0062] In this way, the processing unit of the terminal device can calculate the distance between the colorimeter and the terminal device based on the signal strength of the wireless signal, making it possible to constantly grasp the dynamically changing distance and to promptly select a display state that is appropriate for the user's work status.

[0063] In the terminal device of this embodiment, the processing unit may determine the distance to the colorimeter by performing an averaging process on the signal strength.

[0064] In this way, when calculating distance based on signal strength, problems caused by interference between wireless signals can be avoided, and a display state suited to the user's working state can be reliably achieved.

[0065] In the terminal device of this embodiment, the processing unit may determine that the color of the color measurement result is to be displayed on the terminal display unit instead of on the colorimeter display unit when the signal strength is equal to or greater than a predetermined strength.

[0066] In this way, the control process in the processing section can be simplified and accelerated.

[0067] In the terminal device of this embodiment, the processing unit may determine to display the color of the color measurement result on both the colorimeter display unit and the terminal display unit when the signal strength is less than a predetermined strength.

[0068] In this way, if there is no risk of the user performing an erroneous color measurement operation on the colorimeter, the color of the color measurement result can be displayed on both the colorimeter display unit and the terminal display unit.

[0069] In the terminal device of this embodiment, the processing unit may perform the determination process based on the distance to the colorimeter when an instruction operation for color measurement by the colorimeter is performed.

[0070] In this way, when the user does not issue an instruction to perform colorimetry, there is no need to perform a decision process as to whether or not to display the color of the colorimetry result on the colorimeter display unit, thereby reducing the burden of control processing on the processing unit.

[0071] Another aspect of this embodiment includes a colorimeter unit that performs color measurement, a colorimeter communication unit that communicates with a terminal device, a colorimeter display unit, and a colorimeter processing unit that performs display processing on the colorimeter display unit, and the colorimeter processing unit is related to a colorimeter that performs processing to display the colors of the colorimeter results measured by the colorimeter unit on the colorimeter display unit when communication with the terminal device via the colorimeter communication unit is not established, and determines whether to display the colors of the colorimeter results on the colorimeter display unit based on instruction information from the terminal device to prohibit or allow display when communication with the terminal device via the colorimeter communication unit is established.

[0072] According to this embodiment, if the colorimeter is installed within a distance that allows communication with the terminal device and the user can see the display units of both the terminal device and the colorimeter, the user can measure the color by looking only at the color displayed on the terminal display unit, which has excellent color reproducibility. Therefore, by displaying the color to be measured in different colors on multiple display units, it is possible to prevent the user from confusing the color to be measured with the color of another color patch in the color group and resulting in erroneous color measurement operations using the colorimeter.

[0073] This allows the appropriate display state of the color measurement results to be selected depending on the distance between the colorimeter and the terminal device. As a result, the color being measured is displayed in different colors on both the colorimeter and the terminal device, which prevents the user from confusing the color being measured with the color of another color patch and resulting in incorrect color measurement operations using the colorimeter.

[0074] In the colorimeter of this embodiment, the colorimeter processing unit may perform processing to display the color of the colorimeter result on the colorimeter display unit so as to surround the display area of ​​the numerical value of the colorimeter result.

[0075] In this way, the limited display area of ​​the colorimeter display can be used effectively to provide the user with more information. Also, the user can visually grasp the color tone of the color measurement results together with the numerical parameter information, which helps to avoid confusing the color of the measurement target with the color of another color patch or erroneous color measurement operation of the colorimeter.

[0076] Another aspect of this embodiment relates to a program that causes a computer to function as a communication unit that communicates with a colorimeter including a colorimeter display unit, and a processing unit that performs display processing on the terminal display unit, and the processing unit performs processing to determine whether the color of the colorimeter's color measurement results should be displayed on both the colorimeter display unit and the terminal display unit, or on the terminal display unit, based on the distance from the colorimeter.

[0077] Another aspect of this embodiment relates to a processing method that performs communication with a colorimeter including a colorimeter display unit, display processing on the terminal display unit, and determination processing based on the distance from the colorimeter as to whether the color of the colorimeter's color measurement results should be displayed on both the colorimeter display unit and the terminal display unit, or on the terminal display unit.
