[0004] However, communication between a target device such as the colorimeter described in Patent Document 1 and a control device such as a smartphone may be disconnected unintentionally by the user. For example, when the smartphone goes into a sleep state, the communication between the smartphone and the colorimeter may be disconnected unintentionally by the user. Also, when the colorimeter is not operated continuously for a predetermined period of time or more, the power of the colorimeter may be turned off, and the communication between the smartphone and the colorimeter may be disconnected unintentionally by the user. Therefore, it is necessary to prevent communication between the target device and the control device from being disconnected unintentionally by the user. [Means for solving the problem]

For example, the display panel displays an application setting screen 300 shown in Fig. 3 and a colorimeter setting screen 400 shown in Fig. 4. The touch sensor also receives an operation from the user. The touch sensor generates a signal corresponding to the operation received from the user, and outputs the generated signal to the first control unit 11. The touch sensor detects, for example, an operation on the application setting screen 300 shown in FIG. The touch panel 12 corresponds to an example of a "display unit."

[0017] The first communication interface 13 is a communication interface that performs wireless communication with the colorimeter 2 in accordance with the Bluetooth (registered trademark) standard. The first communication interface 13 includes an antenna for transmitting and receiving Bluetooth (registered trademark) signals, and an interface circuit for processing signals transmitted through the antenna. The first communication interface 13 is an interface board having an antenna and an interface circuit, and is connected to a main board on which the first processor 11A and the like of the first control unit 11 are mounted. Alternatively, the antenna and interface circuit that constitute the first communication interface 13 are mounted on the main board of the first control unit 11. The first communication interface 13 receives second communication conditions from the colorimeter 2, and transmits various instruction information to the colorimeter 2. The first communication interface 13 corresponds to an example of a "first communication unit." The second communication condition will be further described with reference to FIG.

[0018] 1, the colorimeter 2 includes a second control unit 21, an operation mechanism 22, a display mechanism 23, a colorimeter mechanism 24, a second communication interface 25, and a second battery 26. The second battery 26 supplies power to each part of the colorimeter 2. The second control unit 21 controls each part of the colorimeter 2. Each of the operation mechanism 22, the display mechanism 23, the colorimeter mechanism 24, and the second communication interface 25 is connected to the second control unit 21 so as to be able to communicate with each other.

[0019] The second control unit 21 includes a second processor 21A such as a CPU, and a second memory 21B such as a ROM. The second memory 21B stores a second control program PG2.

[0020] The second processor 21A may be configured with multiple processors, or may be configured with a single processor. The second processor 21A may be hardware programmed to realize the functions of each unit described below. That is, the second processor 21A may be configured to have the second control program PG2 installed as a hardware circuit. In this case, the second processor 21A is configured, for example, with an ASIC, an FPGA, or the like. In the following description, the second processor 21A executes the second control program PG2 to thereby realize various functions of the second control unit 21.

[0021] The second memory 21B has a storage area for storing programs executed by the second processor 21A and data processed by the second processor 21A.

The second memory 21B may include, for example, a RAM, etc., as the volatile storage area.

[0022] The operation mechanism 22 is composed of various keys, LEDs (Light Emitting Diodes), etc., and receives operations from a user and outputs to the second control unit 21 an operation signal corresponding to the received operation. The display mechanism 23 includes a display panel such as an LCD, and displays various images on the display panel according to instructions from the second control unit 21.

[0023] The color measurement mechanism 24 measures the color of the image formed on the print medium according to an instruction from the second control unit 21, and outputs the color measurement result to the second control unit 21. The color measurement mechanism 24 has a plurality of color measurement elements. The color measurement element includes a light source that emits detection light and a sensor that receives reflected light. The color measurement element irradiates the image formed on the print medium with the detection light, receives the reflected light reflected by the image with the sensor, and performs color measurement. The color measurement element may include an optical element that separates, reflects, guides, or disperses the light incident on the sensor. The color measurement element may be a colorimeter that measures tristimulus values, or may be a spectrophotometer. The color measurement mechanism 24 outputs the color measurement result of each of the plurality of color measurement elements to the second control unit 21.

[0024] The second communication interface 25 is a communication interface that performs wireless communication with the smartphone 1 in accordance with the Bluetooth (registered trademark) standard. The second communication interface 25 includes an antenna that transmits and receives Bluetooth (registered trademark) signals, and an interface circuit that processes signals transmitted through the antenna.

The second communication interface 25 receives various instruction information from the smartphone 1 and transmits second communication conditions and the like to the smartphone 1. The second communication interface 25 corresponds to an example of a "second communication section."

[0025] Next, the configurations of the first control unit 11 and the second control unit 21 will be described with reference to Fig. 2. Fig. 2 is a diagram showing an example of the configurations of the first control unit 11 and the second control unit 21. The first control unit 11 according to this embodiment includes the first control unit 11 according to the first embodiment and the first control unit 11 according to the second embodiment. In the following description, first, the configuration common to the first control unit 11 according to the first embodiment and the first control unit 11 according to the second embodiment will be described, and then the configuration different between the first control unit 11 according to the first embodiment and the first control unit 11 according to the second embodiment will be described.

[0026] As shown in FIG. 2, the first control unit 11 functionally comprises a first setting unit 111, an acquisition unit 112, a judgment unit 113, a prohibition unit 114, a first display control unit 115, a first communication control unit 116, a first communication condition memory unit 117, and a second communication condition memory unit 118. Specifically, the first processor 11A reads out the first control program PG1 from the first memory 11B and executes the first control program PG1, thereby functioning as a first setting unit 111, an acquisition unit 112, a determination unit 113, a prohibition unit 114, a first display control unit 115, and a first communication control unit 116. In addition, the first processor 11A reads out the first control program PG1 from the first memory 11B and executes the first control program PG1, thereby causing the first memory 11B to function as a first communication condition storage unit 117 and a second communication condition storage unit 118. The first control program PG1 corresponds to an example of a "program".

[0027] The first communication condition storage unit 117 stores the first communication condition C1 in advance. The first communication condition C1 is a condition for transitioning the first communication interface 13 of the smartphone 1 from an active state in which the first communication interface 13 communicates with the colorimeter 2 to a suspended state in which the first communication interface 13 does not communicate with the colorimeter 2. The first communication condition C1 is a condition related to the state of the smartphone 1. The first communication condition C1 includes a first setting condition C11 and a second setting condition C12. The second setting condition C12 is a condition under which the first communication interface 13 is more difficult to transition from an active state to a suspended state than the first setting condition C11. The first communication condition storage unit 117 also stores first setting information SC1 indicating whether the first setting condition C11 or the second setting condition C12 is set. The first setting information SC1 is set by the first setting unit 111 and stored in the first communication condition storage unit 117 by the first setting unit 111.

[0028] The second communication condition storage unit 118 stores the second communication condition C2. The second communication condition C2 is a condition for transitioning the second communication interface 25 of the colorimeter 2 from an active state in which the second communication interface 25 communicates with the smartphone 1 to a suspended state in which the second communication interface 25 does not communicate with the smartphone 1. The second communication condition C2 is a condition related to the state of the colorimeter 2. The second communication condition C2 includes a third set condition C21 and a fourth set condition C22. The fourth set condition C22 is a condition under which it is more difficult for the second communication interface 25 to transition from the active state to the inactive state than the third set condition C21. The second communication condition storage unit 118 stores, for example, second setting information SC2 indicating whether the third setting condition C21 or the fourth setting condition C22 is set as the second communication condition C2. The second setting information SC2 is acquired from the colorimeter 2 by the acquisition unit 112, and is stored in the second communication condition storage unit 118 by the acquisition unit 112. The second communication condition storage unit 118 corresponds to an example of a "storage unit." The third set condition C21 corresponds to an example of the "first set condition." The fourth set condition C22 corresponds to an example of the "second set condition".

[0029] The first setting unit 111 sets the first communication condition C1, which is a condition for transitioning the first communication interface 13 from an active state in which it communicates with the colorimeter 2 to a dormant state in which it does not communicate with the colorimeter 2, to either the first setting condition C11 or the second setting condition C12 in response to operation by the user. For example, the first setting unit 111 sets the first communication condition C1 in response to an operation by the user on the application setting screen 300 displayed on the touch panel 12. The application settings screen 300 is further described with reference to FIG.

[0030] The first communication condition C1 includes a first setting condition C11 and a second setting condition C12. The second setting condition C12 is a condition under which it is more difficult for the first communication interface 13 to transition from an active state to a hibernation state than the first setting condition C11. The first communication condition C1 indicates, for example, a condition under which the smartphone 1 is put into a sleep state. The sleep state corresponds to an example of a "hibernation state." In the sleep state, power supply to the touch panel 12 and the first communication interface 13 is stopped or reduced in order to reduce power consumption of the smartphone 1. As a result, communication between the smartphone 1 and the colorimeter 2 is stopped in the sleep state.

[0031] The first setting condition C11 indicates that the smartphone 1 is to enter a sleep state when the touch panel 12 does not accept any operation from the user for a predetermined period of time or longer. The predetermined period of time is, for example, 10 minutes. The second setting condition C12 indicates that the smartphone 1 does not transition to a sleep state even if the touch panel 12 does not accept any operation from the user for a predetermined time or more. When the first setting condition C11 is the second setting condition C12, in the following description, the predetermined time may be described as, for example, "infinity." In other words, in this embodiment, since the specified time under the second setting condition C12 is longer than the specified time under the first setting condition C11, the second setting condition C12 is a condition in which it is more difficult for the first communication interface 13 to transition from an activated state to a suspended state than the first setting condition C11. However, without being limited to this example, the predetermined time in the first setting condition C11 may be 10 minutes, and the predetermined time in the second setting condition C12 may be 30 minutes. Also, the predetermined time in the first setting condition C11 may be 30 minutes, and the predetermined time in the second setting condition C12 may be "infinity." In other words, it is sufficient that the predetermined time in the second setting condition C12 is longer than the predetermined time in the first setting condition C11. In the smartphone 1, the process of switching between the active state and the sleep state is executed by an operating system (OS) (not shown).

[0032] The first setting unit 111 stores the first setting information SC1 as the first communication condition C1 in the first communication condition storage unit 117. The first setting information SC1 is information indicating whether the first setting condition C11 or the second setting condition C12 is set.

[0033] The acquisition unit 112 acquires, from the colorimeter 2, second communication conditions C2 that are conditions for the colorimeter 2 to transition from an active state in which it communicates with the first communication interface 13 to a dormant state in which it does not communicate with the first communication interface 13. The second communication conditions C2 include a third setting condition C21 and a fourth setting condition C22. The acquisition unit 112 acquires, for example, second setting information SC2 as the second communication condition C2. The second setting information SC2 indicates whether the third setting condition C21 or the fourth setting condition C22 is set in the colorimeter 2. The acquisition unit 112 stores the second setting information SC2 acquired from the colorimeter 2 in the second communication condition storage unit 118 as the second communication condition C2. The second setting information SC2 corresponds to an example of "information indicating a second communication condition."

[0034] In the first control unit 11 according to the first embodiment, for example, when communication between the first communication interface 13 and the colorimeter 2 is established, the acquisition unit 112 acquires the second setting information SC2 from the colorimeter 2. The processing of the first control unit 11 according to the first embodiment will be described with reference to FIG. In the first control unit 11 according to the second embodiment, for example, when the determination unit 113 determines that the second setting condition C12 is set as the first communication condition C1, the acquisition unit 112 acquires the second setting information SC2 from the colorimeter 2. The processing of the first control unit 11 according to the second embodiment will be described with reference to FIG.

[0035] The determination unit 113 determines whether or not the second setting condition C12 is set as the first communication condition C1. Furthermore, the determining unit 113 determines, based on the second setting information SC2 acquired by the acquiring unit 112, whether or not the third setting condition C21 is set as the second communication condition C2.

[0036] In the first control unit 11 according to the first embodiment, for example, when the acquisition unit 112 acquires the second communication condition C2 and the prohibition unit 114 prohibits changing the second communication condition C2 by operating the operation mechanism 22 of the colorimeter 2, the determination unit 113 determines whether or not the second setting condition C12 is set as the first communication condition C1. The processing of the first control unit 11 according to the first embodiment will be described with reference to FIG. In the first control unit 11 according to the second embodiment, for example, when the first communication interface 13 establishes communication with the colorimeter 2, the determination unit 113 determines whether or not the second setting condition C12 is set as the first communication condition C1. The processing of the first control unit 11 according to the second embodiment will be described with reference to FIG.

[0037] The prohibition unit 114 prohibits the colorimeter 2 from changing the second communication conditions C2 through operation of the operation mechanism 22. The prohibition unit 114 instructs the colorimeter 2 to prohibit, for example, changing the second communication conditions C2 through operation of the operation mechanism 22. The prohibition unit 114 transmits, for example, a prohibition command CMR to the colorimeter 2 indicating that changing the second communication conditions C2 through operation of the operation mechanism 22 of the colorimeter 2 is prohibited. When the second control unit 21 of the colorimeter 2 receives the prohibition command CMR from the smartphone 1, it does not accept a change to the second communication conditions C2 through operation of the operation mechanism 22. By providing such a prohibition unit 114, operations related to changing the settings of the colorimeter 2 can be consolidated in the smartphone 1, so that the smartphone 1 can centrally manage the settings of the colorimeter 2. Note that the prohibition unit 114 is not an essential component and may be omitted as appropriate.

[0038] In the first control unit 11 according to the first embodiment, for example, when the acquisition unit 112 acquires the second communication condition C2, the prohibition unit 114 instructs the colorimeter 2 to prohibit the operation of changing the second communication condition C2 in the colorimeter 2. The processing of the first control unit 11 according to the first embodiment will be described with reference to FIG. In the first control unit 11 according to the second embodiment, for example, when an operation to change the second communication condition C2 of the colorimeter 2 from the third setting condition C21 to the fourth setting condition C22 is accepted from the user on the colorimeter setting screen 400, the prohibition unit 114 instructs the colorimeter 2 to prohibit the operation to change the second communication condition C2 in the colorimeter 2. The processing of the first control unit 11 according to the second embodiment will be described with reference to FIG.

[0039] The first display control unit 115 controls the image to be displayed on the touch panel 12. The first display control unit 115 displays, for example, an application setting screen 300 shown in FIG. 3 and a colorimeter setting screen 400 shown in FIG. When the first setting unit 111 receives a first change operation P1 which is an operation for changing the setting of the first communication condition C1 so that the first communication interface 13 is less likely to transition from an active state to a suspended state, the first display control unit 115 causes the touch panel 12 to display second setting information SC2. The second setting information SC2 is information indicating the second communication condition C2. The first change operation P1 is, for example, an operation of changing the first communication condition C1 from the first set condition C11 to the second set condition C12. The first change operation P1 is an operation performed on the application setting screen 300 shown in FIG.

[0040] When the first setting unit 111 accepts a second change operation P2, which is an operation for changing the setting of the first communication condition C1 so that the first communication interface 13 can easily transition from an activated state to a suspended state, the first display control unit 115 does not display the second setting information SC2 on the touch panel 12. The second change operation P2 is, for example, an operation of changing the first communication condition C1 from the second set condition C12 to the first set condition C11. The second change operation P2 is an operation performed on the application setting screen 300 shown in FIG.

[0041] When the first setting unit 111 receives the first change operation P1, if the second communication condition C2 is the third setting condition C21, the display control unit 115 causes the touch panel 12 to display the second setting information SC2. Furthermore, when the first setting unit 111 receives the first change operation P1, if the second communication condition C2 is the fourth setting condition C22, the display control unit 115 does not cause the touch panel 12 to display the second setting information SC2.

[0042] The first communication control unit 116 controls the operation of the first communication interface 13 . For example, when the first communication interface 13 goes from a hibernation state to an active state, the first communication control unit 116 causes the first communication interface 13 to establish communication with the colorimeter 2. "When the first communication interface 13 goes from a hibernation state to an active state" refers to, for example, when the smartphone 1 returns from a sleep state to an active state.

[0043] Furthermore, "when the first communication interface 13 goes from a sleep state to an active state" refers to, for example, when the user activates application software that controls the colorimeter 2 on the smartphone 1. In other words, for example, when an icon corresponding to the application software that controls the colorimeter 2 is touched on a home screen displayed on the touch panel 12 of the smartphone 1. The application software that controls the colorimeter 2 corresponds to the first control program PG1 in this embodiment.

[0044] As shown in FIG. 2, the second control unit 21 functionally comprises a second setting unit 211, a second display control unit 212, a second communication control unit 213, and a second communication condition storage unit 214. Specifically, the second processor 21A reads out the second control program PG2 from the second memory 21B and executes the second control program PG2, thereby functioning as a second setting unit 211, a second display control unit 212, and a second communication control unit 213. In addition, the second processor 21A reads out the second control program PG2 from the second memory 21B and executes the second control program PG2, thereby causing the second memory 21B to function as a second communication condition storage unit 214.

[0045] The second communication condition storage unit 214 stores the second communication condition C2 in advance. The second communication condition C2 is a condition for transitioning the second communication interface 25 from an active state in which the second communication interface 25 communicates with the smartphone 1 to a suspended state in which the second communication interface 25 does not communicate with the smartphone 1. The second communication condition C2 includes a third setting condition C21 and a fourth setting condition C22. The fourth setting condition C22 is a condition for making it more difficult for the second communication interface 25 to transition from the active state to the suspended state than the third setting condition C21. Further, the second communication condition storage unit 214 stores second setting information SC2 indicating whether the third setting condition C21 or the fourth setting condition C22 is set. The second setting information SC2 is set by the second setting unit 211 and stored in the second communication condition storage unit 214 by the second setting unit 211.

[0046] The second setting unit 211 sets a second communication condition C2, which is a condition for transitioning the second communication interface 25 from an active state in which it communicates with the smartphone 1 to a suspended state in which it does not communicate with the smartphone 1, in response to an operation by a user. For example, the second setting unit 211 sets the second communication condition C2 in response to a user operation on the colorimeter setting screen 400 displayed on the touch panel 12 of the smartphone 1. In this case, a command instructing the colorimeter 2 to set the second communication condition C2 is transmitted from the smartphone 1 to the colorimeter 2. The second setting unit 211 sets the second communication condition C2 in response to the command transmitted from the smartphone 1. The colorimeter setting screen 400 will be further described with reference to FIG.

[0047] Also, for example, the second setting unit 211 sets the second communication condition C2 in response to an operation on the operation mechanism 22 by the user. However, when a prohibition command CMR is received from the smartphone 1, the second setting unit 211 prohibits the second communication conditions C2 from being changed by a user's operation of the operation mechanism 22. The prohibition command CMR indicates that the second communication conditions C2 from being changed by an operation of the operation mechanism 22 of the colorimeter 2 is to be prohibited.

[0048] The second communication condition C2 includes a third setting condition C21 and a fourth setting condition C22. The fourth setting condition C22 is a condition under which it is more difficult for the second communication interface 25 to transition from an active state to a hibernation state than the third setting condition C21. The second communication condition C2 indicates, for example, a condition under which the colorimeter 2 is put into a power saving state. The "power saving state" indicates a state in which the power supplied from the second battery 26 to each part of the colorimeter 2 is stopped or reduced. In the power saving state, the power supplied from the second battery 26 to the second communication interface 25 is stopped or reduced, and the second communication interface 25 is put into a hibernation state.

[0049] The third setting condition C21 indicates that the colorimeter 2 is switched to a power saving state when the operation mechanism 22 does not accept any operation for a predetermined time or longer. The predetermined time is, for example, 10 minutes. The fourth setting condition C22 indicates that, for example, even if the operation mechanism 22 does not accept any operation for a predetermined time or more, the colorimeter 2 does not transition to a power saving state. In this case, the predetermined time may be described as, for example, "infinity." In other words, in this embodiment, since the specified time under the fourth setting condition C22 is longer than the specified time under the third setting condition C21, the fourth setting condition C22 is a condition in which it is more difficult for the second communication interface 25 to transition from an activated state to a suspended state than the third setting condition C21. However, without being limited to this example, the predetermined time in the third setting condition C21 may be 10 minutes, and the predetermined time in the fourth setting condition C22 may be 30 minutes. Also, the predetermined time in the third setting condition C21 may be 30 minutes, and the predetermined time in the fourth setting condition C22 may be "infinity." That is, it is sufficient that the predetermined time in the fourth setting condition C22 is longer than the predetermined time in the third setting condition C21. In the colorimeter 2, the process of switching between the active state and the inactive state is executed by an OS (not shown).

[0050] The second setting unit 211 stores the second setting information SC2 as the second communication condition C2 in the second communication condition storage unit 214. The second setting information SC2 is information indicating whether the third setting condition C21 or the fourth setting condition C22 is set.

[0051] The second display control unit 212 controls the image to be displayed on the display mechanism 23 . The second display control section 212 displays, for example, the second setting information SC2. The second setting information SC2 is information indicating whether the third setting condition C21 or the fourth setting condition C22 is set.

[0052] The second communication control unit 213 controls the operation of the second communication interface 25 . The second communication control unit 213 causes the second communication interface 25 to establish communication with the smartphone 1 when, for example, the power of the colorimeter 2 is turned on.

[0053] Furthermore, in response to a request from the acquisition unit 112 of the smartphone 1, the second communication control unit 213 transmits the second setting information SC2 to the smartphone 1. In addition, the second communication control unit 213 receives the prohibition command CMR from the prohibition unit 114 of the smartphone 1 .

[0054] Next, an application setting screen 300 displayed by the touch panel 12 of the smartphone 1 will be described with reference to Fig. 3. Fig. 3 is a screen diagram showing an example of the application setting screen 300 displayed by the touch panel 12. The application setting screen 300 is displayed on the touch panel 12 by the first display control unit 115. An application setting screen 300 shown in FIG. 3 is a screen for making settings for application software (first control program PG1) installed on the smartphone 1, and the operation of the smartphone 1 is determined by these settings.

[0055] The application setting screen 300 includes a sleep condition setting section 310. The sleep condition setting section 310 sets a first communication condition C1 in response to an operation from a user. In other words, the first setting section 111 sets the first communication condition C1 in response to an operation on the sleep condition setting section 310 by the user. The sleep condition setting section 310 includes a title display section 311 and a condition setting section 312 . For example, "Sleep Suppression" is displayed in the title display section 311. "Sleep Suppression" indicates that the smartphone 1 is made to be in a state where it is difficult to transition to a sleep state.

[0056] The condition setting unit 312 displays, for example, "disabled," indicating that the smartphone 1 is set to a state in which it is easy to transition to a sleep state. In this case, the first setting unit 111 sets the first communication condition C1 to the first setting condition C11. The second setting condition C12 indicates, for example, that the predetermined time is, for example, "10 minutes." For example, as shown in Fig. 3, when the user touches the condition setting section 312 in a state in which "Invalid" is displayed on the condition setting section 312, "Valid" is displayed on the condition setting section 312. In this case, the first setting section 111 sets the first communication condition C1 to the second setting condition C12. The second setting condition C12 indicates, for example, that the predetermined time is "infinity".

[0057] The operation of changing the display content of the condition setting portion 312 from "invalid" to "valid" corresponds to an example of a first change operation P1. The operation of changing the display content of the condition setting portion 312 from "enabled" to "disabled" corresponds to an example of a second change operation P2.

[0058] Next, an application setting screen 350 displayed on the touch panel 12 of the smartphone 1 will be described with reference to Fig. 4. Fig. 4 is a screen diagram showing another example of the application setting screen 350 displayed on the touch panel 12. The application setting screen 350 shown in FIG. 4 is displayed on the touch panel 12 by the first display control unit 115 when a first change operation P1 is performed on the application setting screen 300 shown in FIG.

[0059] The application setting screen 350 includes a sleep condition setting section 360. The sleep condition setting section 360 sets a first communication condition C1 in response to an operation by a user. In other words, the first setting section 111 sets the first communication condition C1 in response to an operation by the user on the sleep condition setting section 360. The sleep condition setting section 360 includes a title display section 361 and a condition setting section 362 . For example, "Sleep Suppression" is displayed in the title display portion 361. "Sleep Suppression" indicates that the smartphone 1 is made to be in a state where it is difficult to transition to a sleep state.

[0060] The condition setting unit 362 displays, for example, "enabled." In this case, the first setting unit 111 sets the first communication condition C1 to the second setting condition C12. The second setting condition C12 indicates, for example, that the predetermined time is "infinite." In this case, even if the operation mechanism 22 does not continuously accept an operation, the smartphone 1 does not transition to a sleep state.

[0061] The application setting screen 350 also includes a colorimeter setting accepting section 370. The colorimeter setting accepting section 370 includes a guidance display section 371, an OK button 372, and a change button 373. For example, "The automatic power-off setting value of the colorimeter is 10 minutes" is displayed on the guidance display unit 371. In this case, if the operation mechanism 22 does not accept any operation from the user for 10 minutes or more, the colorimeter 2 is switched to a power saving state.

[0062] The OK button 372 is touched when the user does not want to change the settings of the colorimeter 2. When the OK button 372 is touched, the first display control unit 115, for example, stops the display of the colorimeter setting receiving unit 370. That is, the first display control unit 115, for example, erases the display of the colorimeter setting receiving unit 370.

[0063] The change button 373 is touched when the user wants to change the settings of the colorimeter 2. When the change button 373 is touched, the first display control unit 115 displays, for example, a colorimeter setting screen 400 shown in FIG.

[0064] Next, a colorimeter setting screen 400 displayed by the touch panel 12 of the smartphone 1 will be described with reference to Fig. 5. Fig. 5 is a screen diagram showing an example of the colorimeter setting screen 400 displayed by the touch panel 12. The colorimeter setting screen 400 is displayed on the touch panel 12 by the first display control unit 115 when, for example, the change button 373 shown in Fig. 4 is touched. The colorimeter setting screen 400 in FIG. 5 is a screen for remotely setting the colorimeter 2 via application software (first control program PG1) installed on the smartphone 1.

[0065] The colorimeter setting screen 400 includes a power-off setting section 410. The power-off setting section 410 sets the second communication condition C2 in response to a user operation. In other words, the second setting section 211 sets the second communication condition C2 in response to a user operation on the power-off setting section 410. The power-off setting section 410 includes a title display section 411 and a condition setting section 412 . In the title display section 411, for example, "Automatic power off setting" is displayed, indicating that the condition for turning off the power of the colorimeter 2 is set.

[0066] For example, "10 minutes" is displayed in the condition setting section 412. This indicates that the colorimeter 2 transitions to a power saving state when the operation mechanism 22 does not accept any operation from the user for 10 minutes or more. In this case, the second setting section 211 sets the second communication condition C2 to the third setting condition C21. 6 is displayed when the user touches the condition setting unit 412. In other words, when the user touches the condition setting unit 412, the first display control unit 115 displays the colorimeter setting screen 500 on the touch panel 12. Furthermore, when the first setting unit 111 accepts the first change operation P1, if the second communication condition C2 is the third setting condition C21, the first display control unit 115 displays the colorimeter setting screen 500 on the touch panel 12.

[0067] Next, a colorimeter setting screen 500 displayed by the touch panel 12 of the smartphone 1 will be described with reference to Fig. 6. Fig. 6 is a screen diagram showing another example of the colorimeter setting screen 500 displayed by the touch panel 12. The colorimeter setting screen 500 is displayed on the touch panel 12 by the first display control unit 115.

[0068] The colorimeter setting screen 500 includes a power-off setting section 510. The power-off setting section 510 sets the second communication condition C2 in response to a user operation. In other words, the second setting section 211 sets the second communication condition C2 in response to a user operation on the power-off setting section 510. The colorimeter setting screen 500 is a screen in which a power off setting section 510 is displayed as a pop-up with the colorimeter setting screen 400 as a background image.

[0069] The power-off setting section 510 has a title display section 511 , a condition setting section 512 , a cancel button 513 , and an OK button 514 . In the title display section 511, for example, "Automatic power off setting" is displayed, indicating that the condition for turning off the power of the colorimeter 2 is set.

[0070] In the condition setting section 412, for example, "off," "10 minutes," and "30 minutes" are displayed as selectable options. When the user selects "OFF" and touches the OK button 514, the second communication condition C2 is changed from the third setting condition C21 to the fourth setting condition C22. When the user selects "OFF" and touches the OK button 514, for example, the display control unit 115 transmits a command to the colorimeter 2 instructing the colorimeter 2 to change the second communication condition C2 from the third setting condition C21 to the fourth setting condition C22. Then, when the second setting unit 211 of the colorimeter 2 receives this command, it changes the second communication condition C2 from the third setting condition C21 to the fourth setting condition C22.

[0071] Furthermore, if the user selects "30 minutes" and touches the OK button 514, the colorimeter 2 transitions to a power saving state if the operation mechanism 22 does not accept user operations for 30 consecutive minutes or more. In this case, the second communication condition C2 is maintained at the third setting condition C21. However, the condition for transitioning to the power saving state is changed from the operation mechanism 22 not accepting user operations for 10 consecutive minutes or more to the operation mechanism 22 not accepting user operations for 30 consecutive minutes or more. Therefore, compared to the state shown in FIG. 5, it becomes more difficult for the colorimeter 2 to transition to the power saving state.

[0072] Next, the process of the first control unit 11 according to the first embodiment will be described with reference to Fig. 7. Fig. 7 is a flowchart showing an example of the process of the first control unit 11 according to the first embodiment. In Fig. 7, a case will be described in which the first setting condition C11 is set as the first communication condition C1 in the smartphone 1 in the initial state. As shown in FIG. 7, first, in step S101, the first communication control unit 116 determines whether or not the first communication interface 13 has established communication with the second communication interface 25 of the colorimeter 2. When the first communication control unit 116 determines that communication with the second communication interface 25 of the colorimeter 2 has not been established (step S101; NO), the process goes to a standby state. When the first communication control unit 116 determines that communication with the second communication interface 25 of the colorimeter 2 has been established (step S101; YES), the process proceeds to step S103.

[0073] Then, in step S103, the acquisition unit 112 acquires the second communication condition C2 from the colorimeter 2. The acquisition unit 112 acquires, for example, second setting information SC2 as the second communication condition C2. The second setting information SC2 indicates which of the first setting condition C11 and the second setting condition C12 is set in the colorimeter 2. Next, in step S105, the prohibition unit 114 prohibits the colorimeter 2 from changing the second communication condition C2 through operation of the operation mechanism 22 of the colorimeter 2. The prohibition unit 114 transmits, for example, to the colorimeter 2, a prohibition command CMR indicating that changing the second communication condition C2 through operation of the operation mechanism 22 of the colorimeter 2 is prohibited.

[0074] Next, in step S107, the first setting unit 111 determines whether or not a first change operation P1 has been accepted. The first change operation P1 is an operation of changing the first communication condition C1 from the first set condition C11 to the second set condition C12. More specifically, the first change operation P1 is an operation in which the user touches the condition setting unit 312 shown in Fig. 3 to change the display content from "disabled" to "enabled", for example. If the first setting unit 111 determines that the first change operation P1 has not been accepted (step S107; NO), the judgment unit 113 judges that the first setting condition C11 is set as the first communication condition C1, and then the process ends. If the first setting unit 111 determines that the first change operation P1 has been accepted (step S107; YES), the first setting unit 111 changes the first communication condition C1 from the first setting condition C11 to the second setting condition C12. Then, the judgment unit 113 determines that the second setting condition C12 is set as the first communication condition C1, and the process proceeds to step S109.

[0075] Then, in step S109, the determination unit 113 determines whether or not the third setting condition C21 is set as the second communication condition C2, based on the second setting information SC2 acquired by the acquisition unit 112 in step S103. If the determination unit 113 determines that the third setting condition C21 is not set as the second communication condition C2 (step S109; NO), the process ends. If the determination unit 113 determines that the third setting condition C21 is set as the second communication condition C2 (step S109; YES), the process proceeds to step S111. Then, in step S111, the first display control unit 115 displays the second communication condition C2 on the touch panel 12. More specifically, the first display control unit 115 displays, for example, a message such as "The automatic power-off setting value of the colorimeter is 10 minutes" on the touch panel 12, as shown in the guidance display unit 371 of FIG.

[0076] Next, in step S113, the first display control unit 115 determines whether or not an operation to change the second communication condition C2 from the third setting condition C21 to the fourth setting condition C22 has been accepted. More specifically, the first display control unit 115 determines whether or not the following three operations have been accepted in sequence. First, the user touches the change button 373 shown in FIG. 4 to cause the colorimeter setting screen 400 shown in FIG. 5 to be displayed on the touch panel 12. Next, the user touches the condition setting unit 412 to cause the power off setting unit 510 shown in FIG. 6 to be displayed. Next, it is determined whether or not the user has changed the second communication condition C2 from the third setting condition C21 to the fourth setting condition C22 by operating the power off setting unit 510. If the first display control unit 115 determines that an operation to change the second communication condition C2 from the third setting condition C21 to the fourth setting condition C22 has not been accepted (step S113; NO), the process ends. If the first display control unit 115 determines that an operation to change the second communication condition C2 from the third setting condition C21 to the fourth setting condition C22 has been accepted (step S113; YES), the process proceeds to step S115. Then, in step S115, the first display control unit 115 transmits a command to the colorimeter 2 to instruct the colorimeter 2 to change the second communication condition C2 from the third setting condition C21 to the fourth setting condition C22. When the second setting unit 211 of the colorimeter 2 receives this command, it changes the second communication condition C2 from the third setting condition C21 to the fourth setting condition C22. Then, the process ends.

[0077] Next, the process of the first control unit 11 according to the second embodiment will be described with reference to Fig. 8. Fig. 8 is a flowchart showing an example of the process of the first control unit 11 according to the second embodiment. In Fig. 8, a case will be described in which the first setting condition C11 is set as the first communication condition C1 in the smartphone 1 in the initial state. As shown in FIG. 8, first, in step S201, the first communication control unit 116 determines whether or not the first communication interface 13 has established communication with the second communication interface 25 of the colorimeter 2. When the first communication control unit 116 determines that communication with the second communication interface 25 of the colorimeter 2 has not been established (step S201; NO), the process goes to a standby state. When the first communication control unit 116 determines that communication with the second communication interface 25 of the colorimeter 2 has been established (step S201; YES), the process proceeds to step S203.

[0078] Next, in step S203, the first setting unit 111 determines whether or not a first change operation P1 has been accepted. The first change operation P1 is an operation of changing the first communication condition C1 from the first set condition C11 to the second set condition C12. More specifically, the first change operation P1 is an operation in which the user touches the condition setting unit 312 shown in Fig. 3 to change the display content from "disabled" to "enabled", for example. If the first setting unit 111 determines that the first change operation P1 has not been accepted (step S203; NO), the judgment unit 113 judges that the first setting condition C11 is set as the first communication condition C1, and then the process ends. If the first setting unit 111 determines that the first change operation P1 has been accepted (step S203; YES), the first setting unit 111 changes the first communication condition C1 from the first setting condition C11 to the second setting condition C12. Then, the judgment unit 113 determines that the second setting condition C12 is set as the first communication condition C1, and the process proceeds to step S205. Then, in step S205, the acquisition unit 112 acquires the second communication condition C2 from the colorimeter 2. The acquisition unit 112 acquires, for example, second setting information SC2 as the second communication condition C2. The second setting information SC2 indicates which of the first setting condition C11 and the second setting condition C12 is set in the colorimeter 2.

[0079] Next, in step S207, the determination unit 113 determines, based on the second setting information SC2 acquired by the acquisition unit 112, whether or not the third setting condition C21 is set as the second communication condition C2. If the determination unit 113 determines that the third setting condition C21 is not set as the second communication condition C2 (step S207; NO), the process ends. If the determination unit 113 determines that the third setting condition C21 is set as the second communication condition C2 (step S207; YES), the process proceeds to step S209. Then, in step S209, the first display control unit 115 displays the second communication condition C2 on the touch panel 12. More specifically, the first display control unit 115 displays a message such as "The automatic power-off setting value of the colorimeter is 10 minutes" on the touch panel 12, as shown in the guidance display unit 371 of FIG.

[0080] Next, in step S211, the first display control unit 115 determines whether or not an operation to change the second communication condition C2 from the third setting condition C21 to the fourth setting condition C22 has been accepted. More specifically, the first display control unit 115 determines whether or not the following three operations have been accepted in sequence. First, the user touches the change button 373 shown in FIG. 4 to cause the colorimeter setting screen 400 shown in FIG. 5 to be displayed on the touch panel 12. Next, the user touches the condition setting unit 412 to cause the power off setting unit 510 shown in FIG. 6 to be displayed. Next, it is determined whether or not the user has changed the second communication condition C2 from the third setting condition C21 to the fourth setting condition C22 by operating the power off setting unit 510. If the first display control unit 115 determines that an operation to change the second communication condition C2 from the third setting condition C21 to the fourth setting condition C22 has not been accepted (step S211; NO), the process ends. If the first display control unit 115 determines that an operation to change the second communication condition C2 from the third setting condition C21 to the fourth setting condition C22 has been accepted (step S211; YES), the process proceeds to step S213. Then, in step S213, the first display control unit 115 transmits a command to the colorimeter 2 to instruct the colorimeter 2 to change the second communication condition C2 from the third setting condition C21 to the fourth setting condition C22. Upon receiving this command, the second setting unit 211 of the colorimeter 2 changes the second communication condition C2 from the third setting condition C21 to the fourth setting condition C22. Next, in step S215, the prohibition unit 114 prohibits the colorimeter 2 from changing the second communication conditions C2 through operation of the operation mechanism 22 of the colorimeter 2. The prohibition unit 114 transmits, for example, a prohibition command CMR indicating that the second communication conditions C2 are prohibited from being changed through operation of the operation mechanism 22 of the colorimeter 2 to the colorimeter 2. When the prohibition command CMR is received, the colorimeter 2 prohibits the second communication conditions C2 from being changed through operation of the operation mechanism 22. Then, the process ends.

[0081] 7 and 8, the first control unit 11 according to the second embodiment is different from the first control unit 11 according to the first embodiment in the following two points. That is, the timing at which the acquisition unit 112 acquires the second communication condition C2 from the colorimeter 2 and the timing at which the prohibition unit 114 prohibits a change in the second communication condition C2 through the operation of the operation mechanism 22 of the colorimeter 2 are different.

[0082] In the first control unit 11 according to the first embodiment, the acquisition unit 112 acquires the second communication conditions C2 from the colorimeter 2 when communication is established between the smartphone 1 and the colorimeter 2. In contrast, in the first control unit 11 according to the second embodiment, the acquisition unit 112 acquires the second communication conditions C2 from the colorimeter 2 when the determination unit 113 determines that the second setting conditions C12 are set as the first communication conditions C1.

[0083] In the first control unit 11 according to the first embodiment, when the acquisition unit 112 acquires the second communication condition C2 from the colorimeter 2, the prohibition unit 114 prohibits changing the second communication condition C2 through operation of the operation mechanism 22 of the colorimeter 2. In contrast, in the first control unit 11 according to the second embodiment, when the first display control unit 115 issues an instruction to change the second communication condition C2 to the fourth setting condition C22, the prohibition unit 114 prohibits changing the second communication condition C2 through operation of the operation mechanism 22 of the colorimeter 2.

[0084] As described above with reference to Figures 1 to 8, the smartphone 1 of this embodiment includes a first communication interface 13 that communicates with the colorimeter 2, a first setting unit 111 that sets a first communication condition C1, which is a condition for transitioning the first communication interface 13 from an active state in which it communicates with the colorimeter 2 to a sleep state in which it does not communicate with the colorimeter 2, in response to an operation from a user, an acquisition unit 112 that acquires from the colorimeter 2 a second communication condition C2, which is a condition for transitioning the colorimeter 2 from an active state in which it communicates with the first communication interface 13 to a sleep state in which it does not communicate with the first communication interface 13, and a first display control unit 115 that controls the touch panel 12.When the first setting unit 111 accepts a first change operation P1, which is an operation for changing the setting of the first communication condition C1 so that the first communication interface 13 is less likely to transition from the active state to the sleep state, the first display control unit 115 displays information indicating the second communication condition C2 on the touch panel 12.

[0085] According to this, when the first setting unit 111 accepts the first change operation P1, the first display control unit 115 causes information indicating the second communication condition C2 to be displayed on the touch panel 12. The first change operation P1 is an operation for changing the setting of the first communication condition C1 so that the first communication interface 13 is less likely to transition from an active state to a suspended state. That is, when the user changes the setting of the first communication condition C1 to prevent the disconnection of communication between the smartphone 1 and the colorimeter 2, information indicating the second communication condition C2 is displayed on the touch panel 12. This allows the user to easily confirm the second communication condition C2. This makes it possible to prevent the communication between the colorimeter 2 and the smartphone 1 from being disconnected unintentionally by the user.

[0086] In addition, in the smartphone 1, when the first setting unit 111 accepts a second change operation P2, which is an operation for changing the setting of the first communication condition C1 so that the first communication interface 13 can easily transition from an activated state to a suspended state, the first display control unit 115 does not display information indicating the second communication condition C2 on the touch panel 12.

[0087] According to this, when the first setting unit 111 accepts the second change operation P2, the first display control unit 115 does not display information indicating the second communication condition C2 on the touch panel 12. The second change operation P2 is an operation for changing the setting of the first communication condition C1 so that the first communication interface 13 can easily transition from the activated state to the inactive state. That is, when the user changes the setting of the first communication condition C1 so as to promote the disconnection of communication between the smartphone 1 and the colorimeter 2, information indicating the second communication condition C2 is not displayed on the touch panel 12. This makes it possible to prevent information unnecessary for the user from being displayed on the touch panel 12. This improves user convenience.

[0088] In addition, in the smartphone 1, the second communication condition C2 includes a third setting condition C21 and a fourth setting condition C22 which is a condition under which the colorimeter 2 is less likely to transition to a hibernation state than the third setting condition C21, and when the first setting unit 111 accepts the first change operation P1, if the second communication condition C2 is the third setting condition C21, the first display control unit 115 causes the touch panel 12 to display information indicating the second communication condition C2.

[0089] According to this, when the first setting unit 111 accepts the first change operation P1, if the second communication condition C2 is the third setting condition C21, the first display control unit 115 causes the touch panel 12 to display information indicating the second communication condition C2. That is, when the user changes the setting of the first communication condition C1 so as to suppress disconnection of communication between the smartphone 1 and the colorimeter 2, if the second communication condition C2 is the third set condition C21, information indicating the second communication condition C2 is displayed on the touch panel 12. Thus, the user can easily confirm that the second communication condition C2 is the third set condition C21. Therefore, the user can easily determine that it is necessary to change the second communication condition C2. The user can determine, for example, that it is necessary to change the third set condition C21 to the fourth set condition C22.

[0090] In addition, in the smartphone 1, when the first setting unit 111 accepts the first change operation P1, if the second communication condition C2 is the fourth setting condition C22, the first display control unit 115 does not display information indicating the second communication condition C2 on the touch panel 12.

[0091] According to this, when the user changes the setting of the first communication condition C1 so as to prevent disconnection of communication between the smartphone 1 and the colorimeter 2, if the second communication condition C2 is the fourth setting condition C22, information indicating the second communication condition C2 is not displayed on the touch panel 12. This makes it possible to prevent information unnecessary for the user from being displayed on the touch panel 12. This improves user convenience.

[0092] The smartphone 1 also includes a second communication condition memory unit 118, and the acquisition unit 112 acquires the second communication condition C2 from the colorimeter 2 in advance during initial communication with the colorimeter 2, and stores the second communication condition C2 in the second communication condition memory unit 118.

[0093] According to this, the acquisition unit 112 acquires the second communication conditions C2 from the colorimeter 2 in advance in the initial communication with the colorimeter 2, and stores the second communication conditions C2 in the second communication condition storage unit 118. Therefore, when the first setting unit 111 accepts the first change operation P1, the second communication conditions C2 can be easily acquired. Therefore, the processing of the smartphone 1 can be simplified.

[0094] The smartphone 1 also includes a prohibition unit 114 that prohibits the colorimeter 2 from changing the second communication condition C2 through operation of the operation mechanism 22 of the colorimeter 2 when the second communication condition C2 is the fourth setting condition C22.

[0095] According to this, when the second communication condition C2 is the fourth set condition C22, the prohibition unit 114 prohibits the colorimeter 2 from changing the second communication condition C2 through operation of the operation mechanism 22 of the colorimeter 2. This makes it possible to prevent, for example, the second communication condition C2 from being changed from the fourth set condition C22 to the third set condition C21 through operation of the operation mechanism 22 of the colorimeter 2. This makes it possible to prevent communication between the smartphone 1 and the colorimeter 2 from being disconnected.

[0096] Furthermore, in the smartphone 1, when the first setting unit 111 accepts the first change operation P1, the acquisition unit 112 acquires the second communication condition C2 from the colorimeter 2.

[0097] According to this, when the first setting unit 111 accepts the first change operation P1, the acquisition unit 112 acquires the second communication conditions C2 from the colorimeter 2. Therefore, the acquisition unit 112 can acquire the second communication conditions C2 at an appropriate timing. Therefore, the user can appropriately determine whether or not it is necessary to change the second communication conditions C2.

[0098] Moreover, the control system 100 according to the present embodiment is a control system 100 including a colorimeter 2 and a smartphone 1 that controls the colorimeter 2, in which the colorimeter 2 includes a second communication interface 25, and the smartphone 1 includes a first communication interface 13 that communicates with the second communication interface 25, a first setting unit 111 that sets a first communication condition C1, which is a condition for transitioning the first communication interface 13 from an active state in which communication with the colorimeter 2 is performed to a sleep state in which communication with the colorimeter 2 is not performed, in response to an operation from a user, and the second communication interface 25. The device is equipped with an acquisition unit 112 that acquires from the colorimeter 2 a second communication condition C2, which is a condition for the first communication interface 13 to transition from an active state in which it communicates with the first communication interface 13 to a dormant state in which it does not communicate with the first communication interface 13, and a first display control unit 115 that controls the touch panel 12, and when the first setting unit 111 accepts a first change operation P1, which is an operation for changing the setting of the first communication condition C1 so that the first communication interface 13 is less likely to transition from the active state to the dormant state, the first display control unit 115 causes the touch panel 12 to display information indicating the second communication condition C2.

[0099] This provides the same effects as those provided by the smartphone 1 described above.

[0100] In addition, the first control program PG1 in this embodiment causes the first processor 11A, which controls the first communication interface 13 that communicates with the colorimeter 2, to function as a first setting unit 111 that sets a first communication condition C1, which is a condition for transitioning the first communication interface 13 from an active state in which it communicates with the colorimeter 2 to a sleep state in which it does not communicate with the colorimeter 2, in response to an operation from the user, an acquisition unit 112 that acquires, from the colorimeter 2, a second communication condition C2, which is a condition for transitioning the colorimeter 2 from an active state in which it communicates with the first communication interface 13 to a sleep state in which it does not communicate with the first communication interface 13, and a first display control unit 115 that controls the touch panel 12.When the first setting unit 111 accepts a first change operation P1, which is an operation for changing the setting of the first communication condition C1 so that the first communication interface 13 is less likely to transition from an active state to a sleep state, the first display control unit 115 causes information indicating the second communication condition C2 to be displayed on the touch panel 12.

[0101] This provides the same effects as those provided by the smartphone 1 described above.
