Description

TECHNICAL FIELD

[0001] The present application relates to a terminal device, a colorimeter, a recording medium, and a processing method. BACKGROUND

[0002] In Patent Literature 1, a color measurement method that reliably detects a color patch in which an abnormality exists in a color measurement value is disclosed. The color measurement method implements color measurement by a computer that has: a chart image display section that displays a color measurement result of a color patch on a color chart in an overlapping manner; a comparison determination section that compares the color measurement result with a reference value; a warning section that performs warning display in a manner that makes an abnormality in the color measurement result flicker on the color chart; and a correction section that performs color measurement again on a color patch determined to be abnormal and corrects the color measurement result.

[0003] In Patent Literature 1, as a color measurement device that prevents overlooking a color patch in which an abnormality exists, a color measurement device that displays warning information in a flickering manner on a computer screen is disclosed. In the case of using the color measurement device disclosed in Patent Literature 1, by also providing a display section on the colorimeter independently of the computer screen and displaying the color of the color measurement result on the display section, it is possible to further improve the convenience of the user. However, it was ascertained that, in this case, if the color reproducibility is different on the computer screen and the display section of the colorimeter, there is a problem in which the user can erroneously operate the colorimeter.

[0021] Hereinafter, the present embodiment will be explained. Note that the present embodiment explained hereinafter is not intended to unduly limit the content of the present disclosure recited in the claims. Furthermore, not all of the contents of the structure explained in the present embodiment are necessarily essential structural elements.

[0022] 1. Terminal device

[0023] Figure 1 A structure example of the terminal device 10 of the present embodiment is shown in FIG. 1. Furthermore, a structure example of the colorimeter 60 is also shown in FIG. 2. The terminal device 10 includes a communication section 30, a terminal display section 40, and a processing section 20. The terminal device 10 is a machine that is separate from the colorimeter 60. As the terminal device 10, 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 can be assumed. Figure 1

[0024] The communication section 30 performs wired or wireless communication with an external device such as the colorimeter 60. Specifically, the processing section 20 causes the communication section 30 to transmit or receive information to or from the colorimeter 60 or the like by performing a control process of communication such as a transmission process and a reception process of information with respect to the communication section 30. The communication section 30 can be implemented by, for example, a communication IC (Integrated Circuit) such as a communication ASIC (Application Specific Integrated Circuit) or a communication processor, or a communication firmware or the like. ​

[0025] The terminal display section 40 implements display of various kinds of information. On the terminal display section 40, display of information received by the terminal device 10 from the colorimeter 60, for example, can be implemented. Further, the terminal display section 40 is also an operation interface that inputs operation information of the user. The terminal display section 40 is, for example, a touch panel, and the user can implement various operations by touching the terminal display section 40 as a touch panel. The terminal display section 40 can be realized by various displays such as a liquid crystal display or an organic EL (Electro Luminescent) display that employs a touch panel method, for example.

[0026] The storage section 50 stores various kinds of information such as programs or data, for example. The storage section 50 functions as a work area of the processing section 20 or the communication section 30, for example. The storage section 50 can be realized by a semiconductor memory such as an SRAM (Static Random Access Memory), a DRAM (Dynamic Random Access Memory), a flash memory, a register, a hard disk device, or the like, or a combination thereof.

[0027] The processing section 20 implements control processing of the terminal device 10. The processing section 20 implements various kinds of control processing related to the operation of the terminal device 10 such as control of the communication state of the communication section 30 or control related to display of the terminal display section 40, for example. The processing section 20 can be realized by a logic circuit generated using an automatic configuration wiring method such as a gate array, or various kinds of processors such as a microcomputer.

[0028] The colorimeter 60 implements color measurement. The colorimeter 60 includes a colorimeter communication section 80, a color measurement section 100, a colorimeter display section 90, and a colorimeter processing section 70.

[0029] The color measurement section 100 implements color measurement of a color measurement target such as a printed matter, for example, and outputs a color measurement value as a color measurement result. The color measurement section 100 can be realized by a color measurement sensor such as a spectrosensory or an image sensor.

[0030] The colorimeter display section 90 displays various kinds of information to the user. Specifically, the colorimeter display section 90 displays a color based on information of the color measured by the color measurement section 100, or displays information necessary for the user to operate the colorimeter 60 or various kinds of state information of the colorimeter 60, for example. The colorimeter display section 90 can be realized by various displays such as a liquid crystal display or an organic EL display.

[0031] The colorimeter processing section 70 implements control processing of the colorimeter 60. For example, control processing of the colorimeter communication section 80, control of the color measurement section 100, control related to display of the colorimeter display section 90, and various kinds of control processing related to the operation of the colorimeter 60. The colorimeter processing section 70 can be implemented by a processor that operates based on program or the like and a memory that stores program or the like.

[0032] The colorimeter communication section 80 implements wired or wireless communication with external devices such as the terminal device 10. The colorimeter communication section 80 can be implemented by, for example, a communication-use IC (Integrated Circuit) such as a communication-use ASIC or a communication-use processor, a communication-use firmware, or the like. In the present embodiment, the colorimeter processing section 70 implements control processing of communication such as transmission processing or reception processing of information by the colorimeter communication section 80, and thereby causes the colorimeter communication section 80 to transmit or receive information to or from external devices such as the terminal device 10. The colorimeter communication section 80 can be implemented by a communication-use IC (Integrated Circuit) or the like similarly to the communication section 30 of the terminal device 10.

[0033] Figure 2 Fig. 6 shows the upper surface of the colorimeter 60 provided with an operation panel. As shown in Fig. 6, on the colorimeter 60, there are provided, for example, a color measurement button 61, a cross key 62, a back key 63, a power button 64, and a colorimeter display section 90. In addition, in the present embodiment, a case where a color measurement result is displayed in the colorimeter display section 90 is shown. Figure 2 Figure 2 The color measurement button 61 is an operation device for a user to instruct the colorimeter 60 to implement color measurement. For example, by the user pressing the color measurement button 61, color measurement is implemented by the color measurement section 100. The cross key 62 is, for example, an operation device for instructing directions such as up, down, left, and right.

[0034] In the present embodiment, the colorimeter 60 is implemented by a colorimeter that is capable of performing color measurement of a color of an object. The colorimeter 60 is capable of performing color measurement of a color of an object by, for example, a color measurement method such as a spectral method, a color matching method, or a color difference method. Figure 2 ​In the colorimeter display section 90, in the uppermost portion, time, battery level, and other status information are displayed. In the area Al below this status information, information on the color that was measured is displayed using the L*a*b* color system. In the L*a*b* color system, L is a numerical parameter that indicates brightness. L takes a value between 0 and 100, and the larger the value, the brighter the color. Further, a and b indicate color, a is a parameter that indicates a change in color from the red color system to the green color system, and b is a parameter that indicates a change in color from the blue color system to the yellow color system. The more a changes in the positive direction, the stronger the red color, and the more it changes in the negative direction, the stronger the green color. Further, the more b changes in the positive direction, the stronger the yellow color, and the more it changes in the negative direction, the stronger the blue color. When a and b are both zero, the color becomes achromatic. ΔE, which is displayed below L, a, and b, is a parameter that indicates a color difference between the color that was measured and the color of the color standard that is the reference.

[0035] Further, as shown in FIG. 9, in the colorimeter display section 90, in the area A2, which is indicated by diagonal lines and surrounds the area Al in which the numerical parameters of L, a, and b are displayed, the color that was measured is displayed. Thus, the user is able to grasp the color that was measured visually while grasping numerical information on the measurement results. Figure 2

[0036] Figure 3 ​Fig. 6 is an example of a screen displayed on the terminal display section 40 of the terminal device 10. Specifically, it is an example of a screen displayed on the terminal display section 40 in a case where the terminal device 10 is in communication with the colorimeter 60 and has received information of a colorimetric result from the colorimeter 60. At the uppermost part of the screen, time, battery level, and the like are displayed. Below this, information on the device of the colorimeter 60 as a communication target, and the like are displayed, and it is shown that the terminal device 10 is in a communication state with the colorimeter 60. Further, in a region B1 below this, information on a color that has been colorimetrically measured by the colorimeter 60 is also displayed on the terminal display section 40 of the terminal device 10. The values of the numerical parameters of L, a, and b of the color that has been colorimetrically measured are displayed on the right side of the region B1. Further, the color that has been colorimetrically measured is displayed in a region B2 around this, which is indicated with a diagonal line. Thus, the user can not only grasp the values of the numerical parameters of L, a, and b, but also visually grasp the colorimetric result. Further, in a region B3 below this, the colorimetric results of the last three times are displayed together with the colorimetric date and time, as a measurement history of the colorimeter 60. In a region B4 at the lowermost part of the screen, an icon corresponding to a colorimetric measurement button, an icon corresponding to a colorimetric result and color chart comparison button, an icon corresponding to a history display button of the colorimetric result, and an icon corresponding to a program library information display button are displayed in this order from the left. These icons are images for enabling a part of the operation performed in the colorimeter 60 to be performed on the screen of the terminal device 10.

[0037] Figure 4 The state of the user performing a colorimetric measurement check using the colorimeter 60 and the terminal device 10 is shown. In Figure 4 The user is performing a colorimetric measurement of a colorimetric measurement target object configured to oppose the lower surface of the colorimeter 60 using the colorimeter 60. The colorimetric measurement target object is a product or a color chart, or the like, having a color to be colorimetrically measured. First, the user places the colorimeter 60 over the color to be colorimetrically measured among the colors of the colorimetric measurement target object, and presses the colorimetric measurement button 61 of the colorimeter 60. Then, information on the color of the colorimetric measurement target object is measured by the colorimetric measurement section 100 provided in the lower part of the colorimeter 60, and the colorimetric result is displayed on the colorimeter display section 90. Further, the user can perform the above-described operation of the colorimeter 60 while confirming the colorimetric result colorimetrically measured by the colorimeter 60 on the terminal display section 40 of the terminal device 10 in a communication state with the colorimeter 60. In this case, the user performs the operation of the colorimeter 60 with the right hand, and holds the terminal device 10 with the left hand. Thus, in a case where the user performs a colorimetric measurement of a colorimetric measurement target object using the colorimeter 60 and the terminal device 10, the distance D between the colorimeter 60 and the terminal device 10 is usually several tens of centimeters or so.

[0038] Next, points of concern in a case where a user uses the terminal device 10 together with the colorimeter 60 in such a manner to perform color measurement will be described. In a color inspection process of a color carried by a color measurement target, a color group including a plurality of color patches is generally provided, and color measurement is performed in a predetermined order with respect to each color patch belonging to the color group. Then, if the color to be inspected becomes a predetermined color, it is determined to be normal, and if it does not become the predetermined color, it is determined to be abnormal. Therefore, it is necessary to inspect each color patch belonging to the color group without omission, and reliably detect a color that does not satisfy the reference of the predetermined color, so as to maintain the quality of products. In Patent Literature 1, an inspection method of using the terminal device 10 together with the colorimeter 60 in order to satisfy such a need is disclosed. According to the method, a color patch that is prescribed in advance in the terminal device 10 and a color that is measured by the colorimeter 60 are compared, and in a case where a color difference of the color of the color patch corresponding to the measured color satisfies a reference, it is determined to be normal. On the other hand, in a case where the color difference of the color of the color patch corresponding to the measured color does not satisfy the reference, it is determined to be abnormal. Also, in a case where it is determined to be abnormal, by causing a portion of the color patch determined to be the abnormality in the color group to be displayed in a flickering manner on the terminal display portion 40 of the terminal device 10, it is possible to reliably detect a case where the measured color does not satisfy the predetermined quality. Further, in the application of the inspection method of Patent Literature 1, it is possible to cause the colorimeter display portion 90 of the colorimeter 60 to also display the color measurement result together with the terminal display portion 40. In this case, sometimes the measured color is displayed in different color tones on the terminal display portion 40 and the colorimeter display portion 90, respectively. For example, in a case where a display device used in the colorimeter display portion 90 and a display device used in the terminal display portion 40 differ in resolution of colors, reproducibility of colors, and the like, such a difference in color tones is likely to occur. In a case where such a difference in color tones occurs, the user can confuse the color to be measured with the color of another color patch belonging to the color group, and thus cause an erroneous color measurement operation of the colorimeter 60.

[0039] At this point, Figure 1The terminal device 10 of the present embodiment shown includes a communication section 30 that communicates with the colorimeter 60 including the colorimeter display section 90, and a processing section 20 that implements display processing of the terminal display section 40, and the processing section 20 is capable of implementing a judgment process based on the distance from the colorimeter 60, whether to display the color of the colorimetric result on both the colorimeter display section 90 and the terminal display section 40, or to display on the terminal display section 40. That is, the processing section 20, in the case where the distance D between the terminal device 10 and the colorimeter 60 is close and the user is able to observe the display sections of both the terminal device 10 and the colorimeter 60, does not display the color of the colorimetric result on the colorimeter display section 90, but displays on the terminal display section 40. On the other hand, in the case where the distance D between the terminal device 10 and the colorimeter 60 is far apart, a judgment process is implemented to display the color of the colorimetric result on both the terminal display section 40 and the colorimeter display section 90. If this approach is taken, in the case where the user is able to observe the display sections of both the terminal device 10 and the colorimeter 60, the user is able to perform the colorimetric work by observing only the color displayed on the terminal display section 40, which is superior in color reproducibility, and thus is able to avoid the situation of observing multiple display sections that differ in color reproducibility and thus confusing the colors. On the other hand, in the case where the distance D between the terminal device 10 and the colorimeter 60 is far apart, since the color of the colorimetric result is displayed on both the colorimeter display section 90 and the terminal display section 40, the user is able to perform the colorimetric work while observing the colorimeter display section 90 using the colorimeter 60. In this case, since the user is unable to observe the terminal display section 40, even if the color of the colorimetric result is displayed in different colors on both the colorimeter display section 90 and the terminal display section 40, there is no possibility of confusing the colors. That is, by using the terminal device 10 of the present embodiment to perform colorimetry, it is possible to avoid confusion of the color standards within a color group, or erroneous colorimetric operation of the colorimeter 60 resulting therefrom.

[0040] Further, in the judgment process regarding the selection of the display state described above, a predetermined distance Dt can be set as a judgment criterion. The predetermined distance Dt is a distance D that is considered to be a distance D at which the user is able to perform colorimetry while observing either of the colorimeter display section 90 and the terminal display section 40. That is, it is assumed that the predetermined distance Dt is on the order of tens of centimeters as described above. For example, in the case where the distance D is equal to or less than the predetermined distance Dt, the user is able to perform colorimetry while observing the colorimeter display section 90 as in the case where the distance D is equal to or less than the distance Dth, and thus the color of the colorimetric result is displayed on the colorimeter display section 90 and the terminal display section 40. Figure 4As explained in the foregoing, the user can observe the state of the terminal display section 40 of the terminal device 10 held by the other hand while operating and observing the colorimetry display section 90 of the colorimeter 60 with one hand. In this case, by not displaying the color of the colorimetry result on the colorimetry display section 90 but displaying it only on the terminal display section 40, the user can avoid confusing the color indices within the color group or erroneous colorimetry operation of the colorimeter 60 resulting therefrom. However, in the case where the distance D is greater than the predetermined distance Dt, the user cannot operate the colorimeter 60 while observing the terminal display section 40 of the terminal device 10. That is, the user is not in the state of operating the colorimeter 60 with one hand while holding the terminal device 10 with the other hand as explained in the foregoing. Therefore, the terminal display section 40 of the terminal device 10 cannot be observed. Therefore, in this case, even if the color of the colorimetry result is displayed on both the colorimetry display section 90 and the terminal display section 40, the user does not confuse the color indices within the color group or the like. Therefore, in the case where the distance D is greater than the predetermined distance Dt, it can be judged that the color of the colorimetry result is displayed on both the colorimetry display section 90 and the terminal display section 40. Figure 4 As explained in the foregoing, the user can observe the state of the terminal display section 40 of the terminal device 10 held by the other hand while operating and observing the colorimetry display section 90 of the colorimeter 60 with one hand. In this case, by not displaying the color of the colorimetry result on the colorimetry display section 90 but displaying it only on the terminal display section 40, the user can avoid confusing the color indices within the color group or erroneous colorimetry operation of the colorimeter 60 resulting therefrom. However, in the case where the distance D is greater than the predetermined distance Dt, the user cannot operate the colorimeter 60 while observing the terminal display section 40 of the terminal device 10. That is, the user is not in the state of operating the colorimeter 60 with one hand while holding the terminal device 10 with the other hand as explained in the foregoing. Therefore, the terminal display section 40 of the terminal device 10 cannot be observed. Therefore, in this case, even if the color of the colorimetry result is displayed on both the colorimetry display section 90 and the terminal display section 40, the user does not confuse the color indices within the color group or the like. Therefore, in the case where the distance D is greater than the predetermined distance Dt, it can be judged that the color of the colorimetry result is displayed on both the colorimetry display section 90 and the terminal display section 40.

[0041] Figure 5 The flowchart of the processing example of the terminal device 10 of the present embodiment will be explained. First, in step SI, the processing section 20 of the terminal device 10 judges whether or not the distance D is equal to or less than the predetermined distance Dt. Specifically, the processing section 20 judges whether or not the distance D between the terminal device 10 and the colorimeter 60 is equal to or less than the predetermined distance Dt (step SI). Then, in the case where it is judged in step SI that the distance D is equal to or less than the predetermined distance Dt (Yes), the processing section 20 of the terminal device 10 makes a judgment not to display the color of the colorimetry result on the colorimetry display section 90 but to display it on the terminal display section 40 (step S2). On the other hand, in the case where it is judged in step SI that the distance D is greater than the predetermined distance Dt (No), the processing section 20 of the terminal device 10 makes a judgment to display the color of the colorimetry result on both the colorimetry display section 90 and the terminal display section 40 (step S3). Then, after steps S2 and S3, the processing is performed in order from step SI again.

[0042] That is, the processing section 20 can display the color of the colorimetric result on the terminal display section 40, not on the colorimeter display section 90, in a case where the distance D between the colorimeter 60 and the terminal device 10 is equal to or less than the predetermined distance Dt. Further, the processing section 20 can determine to display the color of the colorimetric result on both the colorimeter display section 90 and the terminal display section 40 in a case where the distance D between the colorimeter 60 and the terminal device 10 is greater than the predetermined distance Dt. If this approach is employed, the user does not need to perform such a useless control process that the color of the colorimetric result is not displayed on the colorimeter display section 90 even in a case where it is not possible to make a mistake in the color standard within the color group or to perform an erroneous colorimetric operation of the colorimeter 60. That is, the control process that the color of the colorimetric result is not displayed on the colorimeter display section 90 can be executed on the basis of accurate determination that there is a possibility that the user makes a mistake in the color standard.

[0043] Further, the terminal device 10 of the present embodiment can also be realized as a program. That is, the program of the present embodiment causes a computer to function as the communication section 30 that communicates with the colorimeter 60 including the colorimeter display section 90 and the processing section 20 that performs the display process of the terminal display section 40, and the processing section 20 can perform the judgment process whether the color of the colorimetric result of the colorimeter 60 is displayed on both the colorimeter display section 90 and the terminal display section 40 or on the terminal display section 40 on the basis of the distance D from the colorimeter 60. Here, as the computer, a smartphone or a tablet terminal, a wearable terminal such as a smartwatch, a network terminal such as a personal computer, or the like can be assumed. By employing this approach, the same effects as described above can be obtained.

[0044] Further, the terminal device 10 of the present embodiment can also be realized as a processing method. That is, in the processing method of the present embodiment, the communication with the colorimeter 60 including the colorimeter display section 90, the display process of the terminal display section 40, and the judgment process whether the color of the colorimetric result of the colorimeter 60 is displayed on both the colorimeter display section 90 and the terminal display section 40 or on the terminal display section 40 on the basis of the distance D from the colorimeter 60 can be performed. By employing this approach, the same effects as described above can be obtained.

[0045] 2. Detailed processing example

[0046] Next, a detailed processing example of the present embodiment will be described. In the terminal device 10 of the present embodiment, the result of the judgment processing can be transmitted to the colorimeter 60 via the communication section 30 of the terminal device 10. For example, since the color of the colorimetric result is not displayed on the colorimeter display section 90 but on the terminal display section 40 in the case where the distance D between the terminal device 10 and the colorimeter 60 is equal to or less than the predetermined distance Dt, the colorimeter 60 is instructed to be prohibited from displaying the color of the colorimetric result on the colorimeter display section 90. On the other hand, since the color of the colorimetric result is displayed on both the colorimeter display section 90 and the terminal display section 40 in the case where the distance D is greater than the predetermined distance Dt, the colorimeter 60 is instructed to be permitted to display the color of the colorimetric result on the colorimeter display section 90. In this way, the colorimeter 60 can be instructed to permit or prohibit the display on the colorimeter display section 90 as the indication information according to the distance D. Further, the indication information can be transmitted to the colorimeter 60 via the communication section 30 of the terminal device 10.

[0047] That is, the processing section 20 of the terminal device 10 of the present embodiment performs the judgment processing on whether the color of the colorimetric result of the colorimeter 60 is displayed on both the colorimeter display section 90 and the terminal display section 40 or on the terminal display section 40 based on the distance D between the terminal device 10 and the colorimeter 60. Then, the processing section 20 performs the processing of transmitting the indication information of the permitted display or the prohibited display of the color of the colorimetric result on the colorimeter display section 90 to the colorimeter 60 via the communication section 30 based on the result of the judgment. By transmitting such indication information, the colorimeter 60 can judge whether the display is permitted or prohibited based on the indication information, and further change the display state. For example, in the case where the distance D between the terminal device 10 and the colorimeter 60 is close and the user can observe both the colorimeter display section 90 and the terminal display section 40, it is necessary to not display the colorimetric result on the terminal display section 40 as described above so as not to confuse the user with the color scale within the color group or the like. In this case, since the indication information of the prohibited display of the colorimetric result on the colorimeter display section 90 is transmitted from the terminal device 10 to the colorimeter 60, the colorimeter 60 can not display the colorimetric result on the colorimeter display section 90 based on the indication information. On the other hand, in the case where the distance D is far and the user can only observe the colorimeter display section 90, there is no possibility of confusing the user with the color scale within the color group or the like even if the colorimetric result is displayed on the terminal display section 40 as described above. In this case, since the indication information of the permitted display of the colorimetric result on the colorimeter display section 90 is transmitted from the terminal device 10 to the colorimeter 60, the colorimeter 60 can display the colorimetric result on the colorimeter display section 90 based on the indication information.

[0048] Further, as described above, the processing section 20 of the terminal device 10 performs the judgment process of whether to display the color of the colorimetric result on both the colorimeter display section 90 and the terminal display section 40 or on the terminal display section 40 based on the distance D between the terminal device 10 and the colorimeter 60. Then, the judgment result is transmitted as the instruction information from the communication section 30 of the terminal device 10 to the colorimeter 60. Specifically, the instruction information is transmitted from the communication section 30 of the terminal device 10 to the colorimeter communication section 80 of the colorimeter 60. Then, based on the instruction information, the display state of the colorimeter display section 90 is changed by the control of the colorimeter processing section 70.

[0049] Further, in performing the judgment process of whether to display the color of the colorimetric result of the colorimeter 60 on both the colorimeter display section 90 and the terminal display section 40 or on the terminal display section 40, it is desirable that the processing section 20 always grasp the distance D between the terminal device 10 and the colorimeter 60. This is because the judgment of whether the distance D is below the predetermined distance Dt changes fluidly depending on the usage state of the colorimeter 60 and the terminal device 10 of the user. Here, as a method of always grasping the distance D, a distance determination method based on the received signal strength of the beacon signal can be used. Hereinafter, the determination method will be described.

[0050] Generally, it is known that, in a case where the distance between a device that transmits a wireless signal and a device that receives the wireless signal is set to d, the received signal strength RSSI (Received Signal Strength Indication) of the wireless signal received by the device weakens in inverse proportion to the square of the distance d within the distance d. Therefore, if the received signal strength RSSI at a position that is only a reference distance away from the transmitting-side device is set to a reference signal strength value SIs, the distance d can be expressed by Equation (1).

[0051] Mathematical Expression 1

[0052]

[0053] For example, in a case where the reference distance is set to 1 meter, the reference signal strength value SIs is 4, and in a case where the measured received signal strength RSSI is 1, the distance d becomes 2 meters. In this way, the distance d between the transmitting-side device and the receiving-side device can be calculated by the operation based on the reference signal strength value SIs and the received signal strength RSSI.

[0054] In order to perform the judgment using the distance of the wireless signal, it can be realized by, for example, transmitting and receiving a beacon signal containing information such as the above-described reference signal strength value SIs between the transmitting-side device and the receiving-side device.Figure 6 For example, the data structure of a beacon signal. Figure 6 As shown, the beacon signal includes information such as the source address, terminal device identification information, reference signal strength value, and device usage history formed by the user. The source address refers to the address information indicating the source of the beacon signal, such as the device address of Bluetooth (Bluetooth is a registered trademark), such as Bluetooth Low Energy (BLE). The device identification information is information that uniquely identifies the device as the source, such as a MAC address. As mentioned earlier, the reference signal strength value SIs is the received signal strength RSSI value received by the receiving device at a distance from the transmitting device that serves only as a reference, and is used when inferring the distance between devices implementing wireless communication. Additionally, the beacon signal may also contain... Figure 6 Data not included in the data structure example can, conversely, be omitted. Figure 6 Part of the data.

[0055] Figure 7 Based on the above description, an example of the dependence of the signal strength SI received by the terminal device 10 on the distance D is shown. That is, the signal strength SI is represented by equation (2).

[0056] Mathematical formula 2

[0057]

[0058] Since the signal strength SI is inversely proportional to the square of the distance D, it decreases sharply as the distance D increases in a short distance, and decreases slowly as the distance D becomes larger. Therefore, when the distance D is calculated from the signal strength SI using the judgment method of the distance based on the received signal strength of the beacon signal, by previously saving information corresponding to the relational expression of Equation (2) and the reference signal strength value SIs in the storage section 50 of the terminal device 10, and substituting the measured signal strength SI, the distance D can be calculated by calculation. Alternatively, the information of Equation (2) can be previously saved in the storage section 50 as a lookup table, and based on the reference signal strength value SIs and the measured signal strength SI, the appropriate data can be taken out from the lookup table, and the distance D can be calculated. The processing section 20 can perform a comparison of the distance D calculated in this way and the predetermined distance Dt, and perform a judgment process of whether to display the color of the color measurement result on the colorimeter display section 90. In addition, it is considered that in the case where the user puts the terminal device 10 in a pocket or a bag, etc., although the actual distance is close, since the measured signal strength SI is weak, it can be judged that the distance D is far. However, since it can be considered that the user does not observe the display of the terminal device 10 in such a case, there is no problem in causing the colorimeter 60 to perform the display in the case where the distance D is far. That is, only the distance D that is assumed in the case where the terminal device 10 and the colorimeter 60 are in an ideal state needs to be calculated.

[0059] Figure 8 is expressed as Figure 5 The flowchart of the processing example in the case where the above-described judgment method of the distance based on the received signal strength of the beacon signal is applied in the processing example described above. That is, in the processing example described above Figure 8In the processing example, the communication section 30 performs communication with the colorimeter 60 by wireless communication, and the processing section 20 judges the distance D between the terminal device 10 and the colorimeter 60 on the basis of the signal strength SI of the wireless communication. First, in step Sll, the terminal device 10 judges whether or not communication is being performed with the colorimeter 60 by wireless communication. Specifically, the processing section 20 of the terminal device 10 judges whether or not the communication section 30 is performing communication with the colorimeter communication section 80 of the colorimeter 60 by wireless communication (step Sll). Specifically, the processing section 20 judges whether or not wireless communication between the communication section 30 and the colorimeter communication section 80 is established. Next, in the case where it is judged in step Sll that wireless communication is being performed (YES), the processing section 20 calculates the distance D on the basis of the signal strength SI and by arithmetic operation, and judges whether or not the distance D is below the predetermined distance Dt (step S12). Then, in the case where it is judged in step S12 that the distance D is below the predetermined distance Dt (YES), the processing section 20 makes a judgment to the effect that the color of the color measurement result is displayed on the terminal display section 40 rather than on the colorimeter display section 90 (step S13). On the other hand, in the case where it is judged by the processing section 20 in step Sll that the communication section 30 is not performing communication with the colorimeter 60 by wireless communication (NO) or in the case where it is judged by the processing section 20 in step S12 that the distance D is greater than the predetermined distance Dt (NO), the processing section 20 makes a judgment to the effect that the color of the color measurement result is displayed on both the colorimeter display section 90 and the terminal display section 40 (step S14). Then, after steps S13 and S14, the processing is performed in order from step Sll again.

[0060] If this approach is taken, the processing section 20 of the terminal device 10 is able to calculate the distance D of the colorimeter 60 from the terminal device 10 on the basis of the signal strength SI of the wireless signal. Therefore, even in the case where the distance D between the terminal device 10 and the colorimeter 60 changes fluidly due to the user's working state, the distance D can be grasped at all times. Therefore, the display state that is appropriate for the user's working state can be selected without delay.

[0061] Further, in the case where the distance D is calculated using the signal strength SI that has been subjected to averaging processing, the distance D can be calculated using the signal strength SI that has been subjected to averaging processing. As explained in the Figure 8 Figure 7 As explained in the above-described example, the dependence of the signal strength SI on the distance D is inversely proportional to the square of the distance D. However, in actuality, since there is interference of the wireless signals with one another, the greater the separation of the devices, the greater the departure from equation (1). Therefore, by measuring the signal strength SI a plurality of times and using the average value thereof to calculate the distance D, it is possible to reduce the departure from equation (1) that is caused by the interference of the wireless signals with one another.​Figure 9 In this case, a processing example in this case is shown by a flowchart. The difference from Figure 8 is that, when communication is performed by wireless communication in step Sll of Figure 8 , YES, in step S22 of Figure 9 , a step of calculating an average value of the signal strength SI for N times is added, and, in step S23 of Figure 8 corresponding to step S12 of Figure 9 , a determination is not made as to whether the signal strength SI is above the predetermined strength SIt, but a determination is made as to whether the signal strength SI to which the averaging process has been performed is above the predetermined strength SIt.

[0062] Here, as a method of the averaging process of the signal strength SI, a method shown by a flowchart of Figure 10 may be used. First, after the processing section 20 detects the pressing of the color measurement button 61 by the user (step S31), the colorimeter 60 performs the measurement of the signal strength SI for a predetermined number of times (step S32). In Figure 10 , the predetermined number of times is recorded as N times. N is an integer of 2 or more. Then, the processing section 20 performs the averaging process with respect to the data of the signal strength SI for N times, and calculates the average value of the signal strength SI (step S33). That is, in the averaging method shown in Figure 10 , the processing section 20 does not always perform the measurement of the signal strength SI of the wireless signal, but performs the measurement of the signal strength SI in the case where the color measurement button 61 of the colorimeter 60 is pressed by the user is detected.

[0063] On the other hand, Figure 11 , the method of the averaging process is a method in which the terminal device 10 periodically performs the measurement of the signal strength SI of the wireless signal. First, as in the case of Figure 10 , the processing section 20 detects the pressing of the color measurement button 61 of the colorimeter 60 by the user (step S41). Next, in the method of Figure 11 , the average value of the signal strength SI for the most recent N times is calculated (step S42). That is, the processing section 20 performs the averaging process of the data of the signal strength SI for N times measured until the pressing of the color measurement button 61 is detected, with reference to the data. Here, in the method of the averaging process shown in Figure 10 , since the processing section 20 does not periodically perform the measurement of the signal strength SI in the background, there is an advantage that the burden of the control process of the processing section 20 is small. On the other hand, in Figure 10In the method of the averaging process shown, the processing section 20 performs the measurement of the signal intensity SI N times after detecting the depression of the color measurement button 61 and performs the averaging process. Therefore, there is a disadvantage of having a time lag from when the user depresses the color measurement button 61 until the indication information of the permission display or the prohibition display of the color of the color measurement result to the colorimeter display section 90 is sent to the colorimeter 60. In this regard, in the Figure 11 In the method of the averaging process shown, since the processing section 20 periodically measures the signal intensity SI in the background, this becomes a disadvantage in that the burden of the control process of the processing section 20 is increased. However, since the processing section 20 periodically measures the signal intensity SI in the background, the time lag from when the user depresses the color measurement button 61 until the indication information of the permission display or the prohibition display of the color of the color measurement result to the colorimeter display section 90 is sent to the colorimeter 60 is reduced, and thus the display state suitable for the user's working state can be selected without delay. In addition, the averaging process can also be performed by any one of an arithmetic mean, a geometric mean, or a harmonic mean, or the like. Furthermore, instead of the signal intensity SI subjected to the averaging process, the median value of the data of the signal intensity SI N times can also be used. That is, in the terminal device 10 of the present embodiment, the processing section 20 performs the averaging process of the signal intensity SI and judges the distance D to the colorimeter 60. If such a method is employed, the adverse situation such as an error caused by the interference of the wireless signals with each other can be reduced when the distance D is calculated based on the signal intensity SI, and thus the display state suitable for the user's working state can be reliably achieved.

[0064] In addition, in the processing example of Figure 8 , Figure 9 , as to whether the distance D is equal to or greater than the predetermined distance Dt, it is also possible to judge by whether the magnitude of the signal intensity SI is equal to or greater than the predetermined intensity SIt. That is, the processing section 20 can judge that the distance D is equal to or less than the predetermined distance Dt in the case where the measured signal intensity SI or the signal intensity SI subjected to the averaging process is equal to or greater than the predetermined intensity SIt. Then, in this case, the processing section 20 can make a judgment of the gist of not displaying the color of the color measurement result on the colorimeter display section 90 but displaying it on the terminal display section 40. On the contrary, the processing section 20 can judge that the distance D is greater than the predetermined distance Dt in the case where the measured signal intensity SI or the signal intensity SI subjected to the averaging process is less than the predetermined intensity SIt. Then, in this case, the processing section 20 can make a judgment of the gist of displaying the color of the color measurement result on both the colorimeter display section 90 and the terminal display section 40. In Figure 12 In the processing example in Figure 8 , Figure 9 , the difference from Figure 8corresponding to the step S23 of the process example shown in FIG. 6. Figure 9 corresponding to the step S23 of the process example shown in FIG. 6. Figure 12 In the step S54, the processing section 20 does not judge whether the distance D is below the predetermined distance Dt, but judges which one of the step S55 or the step S56 to proceed to, based on whether the signal intensity SI or the signal intensity SI subjected to the averaging process is above the predetermined intensity SIt. The above judgment process can be implemented by storing the signal intensity SI at the time when the distance D between the terminal device 10 and the colorimeter 60 becomes the predetermined distance Dt as the predetermined intensity SIt in the storage section 50 of the terminal device 10, for example, in advance, and the processing section 20 compares the measured signal intensity SI and the predetermined intensity SIt. According to this judgment process, the distance D is calculated based on the signal intensity SI and by arithmetic operation, and even if the distance D and the predetermined distance Dt are not compared, the judgment of the permission or prohibition of the display of the color of the colorimetric result on the colorimeter display section 90 can be implemented by directly comparing the signal intensity SI and the predetermined intensity SIt. Therefore, the simplification and the speed-up of the control process in the processing section 20 can be achieved.

[0065] In addition, in the process example shown in FIG. 6, Figure 5 , Figure 8 , Figure 9 , Figure 12 In the process example shown in FIG. 6, the judgment process of whether to display the color of the colorimetric result of the colorimeter 60 on the colorimeter display section 90 or on the terminal display section 40 can be implemented based on the distance D between the terminal device 10 and the colorimeter 60 at the time when the instruction operation of the colorimetry by the colorimeter 60 is implemented.

[0066] If such a method is adopted, the processing section 20 of the terminal device 10 initially implements the judgment process of whether to display the color of the colorimetric result on the colorimeter display section 90 at the time when the user issues the instruction to implement the colorimetry. Therefore, the above judgment process is not implemented at the time when the instruction to implement the colorimetry is not issued from the user, and thus the burden of the control process of the processing section 20 can be reduced.

[0067] As described above, in the case where the colorimetric result is displayed on both the terminal display section 40 of the terminal device 10 and the colorimeter display section 90 of the colorimeter 60, it is possible that the user confuses the color to be the colorimetric object with the color of the other color scale due to the difference in the reproducibility of the colors of the terminal display section 40 and the colorimeter display section 90, and the like.

[0068] At this point, the colorimeter 60 of the present embodiment includes a color measurement section 100 that performs color measurement, a colorimeter communication section 80 that performs communication with the terminal device 10, a colorimeter display section 90, and a colorimeter processing section 70 that performs display processing of the colorimeter display section 90. The colorimeter processing section 70 performs processing to display the color of the color measurement result obtained by the color measurement section 100 on the colorimeter display section 90 in a case where communication between the colorimeter communication section 80 and the terminal device 10 is not established, and performs processing to judge whether or not to display the color of the color measurement result on the colorimeter display section 90 based on the instruction information of prohibition of display or permission of display from the terminal device 10 in a case where communication between the colorimeter communication section 80 and the terminal device 10 is established. Here, as to the colorimeter communication section 80, the colorimeter display section 90, the colorimeter processing section 70, and the color measurement section 100, the same as in the first embodiment, the colorimeter communication section 80 performs communication with the terminal device 10, the colorimeter display section 90 displays the color of the color measurement result, the colorimeter processing section 70 performs display processing of the colorimeter display section 90, and the color measurement section 100 performs color measurement. Figure 1As described above. In the colorimeter 60 of the present embodiment, first, the colorimeter processing section 70 of the colorimeter 60 judges whether or not the communication between the colorimeter communication section 80 and the communication section 30 of the terminal device 10 is established. In the case where the communication is not established, the colorimeter 60 cannot transmit the color measurement result to the terminal device 10. Therefore, the color measurement result is not transmitted from the colorimeter 60 to the terminal device 10, but the process of displaying the color measurement result on the colorimeter display section 90 is executed by the colorimeter processing section 70 of the colorimeter 60. That is, in the case where the communication between the colorimeter 60 and the terminal device 10 is not established, the color measurement result is displayed only on the colorimeter display section 90. Here, in the state where the communication between the colorimeter communication section 80 and the terminal device 10 is not established, the distance D between the colorimeter 60 and the terminal device 10 is apart, although the user can observe the colorimeter display section 90 of the colorimeter 60, since the state where the terminal display section 40 of the terminal device 10 cannot be observed, even if the color measurement result is not displayed on the terminal display section 40 of the terminal device 10, no adverse situation occurs. On the other hand, in the case where the communication is established, the colorimeter processing section 70 of the colorimeter 60 judges whether or not to display the color of the color measurement result on the colorimeter display section 90 based on the instruction information of the prohibition of display or the permission of display from the terminal device 10. In this case, as described above, the terminal device 10 transmits the instruction information of the prohibition of display when the distance D is close, and transmits the instruction information of the permission of display when the distance D is apart. First, the colorimeter 60 receives the instruction information, and in the case where the instruction information is the prohibition of display, does not display the color measurement result on the colorimeter display section 90. Specifically, the colorimeter communication section 80 of the colorimeter 60 receives the instruction information, and based on the instruction information, the colorimeter processing section 70 implements the control process of not displaying the color measurement result on the colorimeter display section 90. Therefore, in the case where the distance D between the colorimeter 60 and the terminal device 10 is close, the color measurement result is displayed only on the terminal display section 40 of the terminal device 10 where the color reproduction is excellent. Therefore, it is possible to avoid the situation where the color measurement result is displayed in different colors on both the colorimeter display section 90 and the terminal display section 40, and the user mistakes the color being measured for the color of another color standard. Further, in the case where the instruction information is the permission of display, the colorimeter communication section 80 of the colorimeter 60 displays the color measurement result on the colorimeter display section 90. Specifically, the colorimeter communication section 80 of the colorimeter 60 receives the instruction information, and based on the instruction information, the colorimeter processing section 70 implements the control process of displaying the color measurement result on the colorimeter display section 90. Therefore, in the case where the distance D between the colorimeter 60 and the terminal device 10 is apart, the color measurement result is displayed on both the colorimeter display section 90 of the colorimeter 60 and the terminal display section 40 of the terminal device 10.In this case, since the distance D is far, the user is in a state of performing the color measurement operation by observing only the colorimeter display section 90 of the colorimeter 60, and can perform the color measurement by observing the color measurement result displayed on the colorimeter display section 90. By adopting such a manner, the appropriate display state of the color measurement result can be selected in accordance with the distance D of the colorimeter 60 from the terminal device 10. Therefore, it is possible to avoid a situation in which the color to be measured is displayed in different colors on both the terminal device 10 and the colorimeter 60, and the user confuses the color to be measured with the colors of other color patches, or an erroneous color measurement operation of the colorimeter 60 caused thereby.

[0069] Further, in the colorimeter 60 of the present embodiment, the color measured can also be displayed in the region A2 of the colorimeter display section 90 as explained in Figure 2 In the colorimeter display section 90, the color measured can be displayed in a manner of surrounding the region Al in which the information of the color measurement result of L, a, b, etc. is displayed. The display area of the colorimeter display section 90 of the colorimeter 60 is mostly narrower than that of the terminal display section 40 of the terminal device 10. Therefore, there is a case in which the numerical parameters of L, a, b, etc. with respect to the color measured are displayed on the colorimeter display section 90, and there is no sufficient space to display the color measured. Therefore, if the present embodiment is configured as such, the limited display area of the colorimeter display section 90 can be effectively used, and more information can be provided to the user. As a result, the user can also visually grasp the color of the color measurement result together with the information of the numerical parameters, and it is possible to avoid a situation in which the color to be measured is confused with the colors of other color patches, or an erroneous color measurement operation of the colorimeter 60.

[0070] As explained above, the terminal device of the present embodiment relates to a terminal device including a communication section that communicates with a colorimeter including a colorimeter display section, and a processing section that performs display processing of a terminal display section, the processing section performing a judgment process of whether to display the color of the color measurement result of the colorimeter on both the colorimeter display section and the terminal display section, or on the terminal display section, based on the distance from the colorimeter.

[0071] According to the present embodiment, in a case in which the user can observe the display sections of both the terminal device and the colorimeter, the user can perform the color measurement by observing only the color displayed in the terminal display section in which the color reproduction is excellent. Therefore, it is possible to avoid a situation in which the color to be measured is displayed in different colors on a plurality of display sections, and the user confuses the color to be measured with the colors of other color patches within the color group, or an erroneous color measurement operation of the colorimeter caused thereby.

[0072] Further, in the terminal device of the present embodiment, the following method can also be employed, that is, the processing section judges to display the color of the color measurement result on the terminal display section instead of the colorimeter display section when the distance from the colorimeter is equal to or less than a predetermined distance.

[0073] If such a method is employed, it is not necessary to implement a useless control process of not displaying the color of the color measurement result on the colorimeter display section even in a case where the user is likely to make a mistake in the color to be measured or perform a color measurement operation with an error.

[0074] Further, in the terminal device of the present embodiment, the following method can also be employed, that is, the processing section judges to display the color of the color measurement result on both the colorimeter display section and the terminal display section when the distance from the colorimeter is greater than a predetermined distance.

[0075] If such a method is employed, since the distance between the colorimeter and the terminal device is separated so that it is necessary to display the color of the color measurement result on both the colorimeter display section and the terminal display section, the color of the color measurement result is displayed on either display section, so it is possible to avoid a case where the confirmation of the color measurement result cannot be performed on the colorimeter display section.

[0076] Further, in the terminal device of the present embodiment, the following method can also be employed, that is, the processing section transmits the indication information of the permitted display or the prohibited display of the color of the color measurement result to the colorimeter via the communication section based on the result of the judgment processing.

[0077] If such a method is employed, the colorimeter can perform the judgment of whether to display the color measurement result on the colorimeter display section based on the indication information transmitted from the terminal device.

[0078] Further, in the terminal device of the present embodiment, the following method can also be employed, that is, the communication section communicates with the colorimeter through wireless communication, and the processing section judges the distance from the colorimeter based on the signal strength of the wireless communication.

[0079] If such a method is employed, since the processing section of the terminal device can calculate the distance from the colorimeter based on the signal strength of the wireless signal, it is possible to always grasp the distance that changes with fluidity, so it is possible to select the display state suitable for the working state of the user without delay.

[0080] Further, in the terminal device of the present embodiment, the following method can also be employed, that is, the processing section performs the averaging processing of the signal strength to judge the distance from the colorimeter.

[0081] If such a method is employed, when distance is calculated based on signal strength, adverse situations caused by interference of wireless signals with each other can be avoided, and thus a display state suitable for the user's operation state can be reliably realized.

[0082] Further, in the terminal device of the present embodiment, the following method can also be employed, that is, the processing section judges to display the color of the colorimetric result on the terminal display section instead of the colorimeter display section when the signal strength is equal to or greater than a predetermined strength.

[0083] If such a method is employed, simplification and speed-up of the control processing in the processing section can be realized.

[0084] Further, in the terminal device of the present embodiment, the following method can also be employed, that is, the processing section judges to display the color of the colorimetric result on both the colorimeter display section and the terminal display section when the signal strength is less than a predetermined strength.

[0085] If such a method is employed, the color of the colorimetric result can be displayed on both the colorimeter display section and the terminal display section when the user does not perform an erroneous colorimetric operation of the colorimeter.

[0086] Further, in the terminal device of the present embodiment, the following method can also be employed, that is, the processing section performs the judgment processing based on the distance from the colorimeter when an instruction operation for colorimetry by the colorimeter is performed.

[0087] If such a method is employed, when an instruction for performing colorimetry is not issued from the user, the judgment processing of whether to display the color of the colorimetric result on the colorimeter display section is not performed, and thus the burden of the control processing of the processing section can be reduced.

[0088] Another aspect of the present embodiment relates to a colorimeter including a colorimetric section that performs colorimetry, a colorimeter communication section that performs communication with a terminal device, a colorimeter display section, and a colorimeter processing section that performs display processing of the colorimeter display section, the colorimeter processing section performing processing of displaying the color of a colorimetric result obtained by the colorimetric section on the colorimeter display section when communication between the colorimeter and the terminal device by the colorimeter communication section is not established, and judging whether to display the color of the colorimetric result on the colorimeter display section based on instruction information of prohibition of display or permission of display from the terminal device when communication between the colorimeter and the terminal device by the colorimeter communication section is established.

[0089] According to the present embodiment, in a case where the colorimeter is disposed at a distance capable of communicating with the terminal device, and the user can observe both the display sections of the terminal device and the colorimeter, the user can perform color measurement by observing only the color displayed on the terminal display section on which the color reproduction is excellent. Thus, it is possible to avoid a case where the color to be measured is displayed in different colors on the plurality of display sections, and the user confuses the color to be measured with the colors of other color standards in the color group, or a color measurement operation of the colorimeter resulting from the confusion.

[0090] By employing such a manner, it is possible to select an appropriate display state of the color measurement result according to the distance between the colorimeter and the terminal device. Thus, it is possible to avoid a case where the color to be measured is displayed in different colors on both the colorimeter and the terminal device, and the user confuses the color to be measured with the colors of other color standards, or a color measurement operation of the colorimeter resulting from the confusion.

[0091] Further, in the colorimeter of the present embodiment, the color measurement result can be displayed on the colorimeter display section by the colorimeter processing section in a manner of surrounding the display region of the numerical value of the color measurement result.

[0092] If such a manner is employed, it is possible to effectively use the limited display area of the colorimeter display section, and thus, it is possible to provide more information to the user. Further, the user can visually grasp the color of the color measurement result together with the information of the numerical value, and thus, it is possible to avoid a case where the color to be measured is confused with the colors of other color standards, or a color measurement operation of the colorimeter resulting from the confusion.

[0093] Another aspect of the present embodiment relates to a program that causes a computer to function as a communication section that communicates with a colorimeter including a colorimeter display section, and a processing section that performs display processing of a terminal display section, and the processing section performs a judgment process of whether to display the color of the color measurement result of the colorimeter on both the colorimeter display section and the terminal display section, or on the terminal display section, based on the distance from the colorimeter.

[0094] Another aspect of the present embodiment relates to a processing method in which a communication with a colorimeter including a colorimeter display section, display processing of a terminal display section, and a judgment process of whether to display the color of the color measurement result of the colorimeter on both the colorimeter display section and the terminal display section, or on the terminal display section, based on the distance from the colorimeter are performed.

[0095] In addition, although the present embodiment has been described in detail as described above, various modifications that do not substantially depart from the novel subject matter and effects of the present disclosure are readily understood by those skilled in the art. Therefore, such modified examples are intended to be included in the scope of the present disclosure. For example, a term recited at least once in the specification or the drawings together with a more general or synonymous different term is capable of being substituted for that different term anywhere in the specification or the drawings. Furthermore, all combinations of the present embodiment and the modified examples are also included in the scope of the present disclosure. Furthermore, the structure, the action, and the like of the terminal device, the colorimeter, the program, and the processing method are not limited to those described in the present embodiment, and various modifications can be made thereto.

[0096] For example, whether to display the color of the colorimetric result of the colorimeter on both the colorimeter display portion and the terminal display portion or on the terminal display portion alone can be implemented by either of the terminal device and the colorimeter or by a device other than either of them.

[0097] Furthermore, the distance D between the terminal device 10 and the colorimeter 60 can be determined based on any method other than the signal strength. For example, it can be determined based on the time taken for a sound emitted by one of the terminal device 10 and the colorimeter 60 to reach the other. Alternatively, it can be determined by another method. It can also be determined without actually calculating the distance, but based on a parameter dependent on the distance, such as a value taking into account the signal strength.
