Description

  The present invention relates to an information processing program, an information processing apparatus, and an information processing method.

  There is a conventional technique for starting another application from one application. For example, Patent Document 1 describes a technique in which a printer driver is activated when data is created by an application and a print instruction is input.

  On the other hand, some portable terminals have a function called “shared function”. The sharing function is a function for passing data processed by the sharing source application to the sharing destination application and processing the data by the sharing destination application. Therefore, by using this sharing function, for example, the image data that is the source of the image displayed on the screen of the mobile terminal by the image display application (share source application) is passed to the print application (share destination application). Can be printed on the printer. Note that, when the sharing source application uses the sharing function, the sharing destination application is activated.

  Some portable terminals are equipped with a hardware key for returning the screen to the previous screen or returning to the immediately preceding application (hereinafter, this hardware key is temporarily referred to as a “BACK key”). When the sharing function is used, the erroneous operation of the BACK key sometimes becomes a problem. For example, if the BACK key is pressed after the sharing destination application is activated by the sharing function, the sharing destination application is terminated and the sharing source application that is the immediately preceding application is returned. Along with this, the RAM area reserved for the sharing destination application is also released. Therefore, even if a preview image based on the image data passed from the sharing source application is created and stored in the RAM, the created preview image is lost due to the RAM area being released by pressing the BACK key. It is highly likely that The larger the number of image data passed from the sharing source application, the longer it takes to create a preview image, so the usability as an application is impaired.

  The present invention has been made in view of the above-described circumstances. When a preview image is displayed, an information processing program, an information processing apparatus, and an information processing program that improve usability by restricting processing for a predetermined operation. And an information processing method.

In order to achieve this object, an information processing program of the present invention is an information processing program as an application that is activated by a second application and causes a computer included in the information processing apparatus to function. Image display control means for displaying an image based on the image data passed from the second application on the display unit, and processing based on the image data passed from the second application when the operation accepting unit accepts the first operation A processing control unit that causes the image data processing unit to execute, an execution unit that executes termination or deactivation of the application when the operation receiving unit receives the second operation, and the display unit displays an image. When the operation accepting unit accepts the second operation, the execution control As limiting means for limiting the execution of the termination or deactivation of the application by, to function, said limiting means, if the number of image data to be passed from the second application is greater than a predetermined threshold value, the execution Execution of the termination or deactivation by means is restricted, and execution of the termination or deactivation is not restricted when the number of the image data is less than the predetermined threshold .

  The present invention can be realized in various modes such as an information processing device, a control device that controls the information processing device, an information processing system, an information processing method, and a recording medium that records an information processing program.

According to the information processing program of claim 1, when the display unit displays an image, even if the operation receiving unit receives the second operation (for example, operation of the BACK key), the application ends. Alternatively, since restrictions are placed on deactivation, each data created by the application can be prevented from being lost when the application is terminated or deactivated. Thereby, it is possible to prevent data loss due to a second operation (for example, an erroneous operation of the BACK key) that is erroneously performed. Therefore, there is an effect that it is possible to improve the usability as an application by eliminating the disadvantage of the user due to an erroneous operation, such as the need to re-create data that requires time.
According to the information processing program of the third aspect, in addition to the effect produced by the information processing program according to any one of the first to seventh aspects, the reception of the second operation by the operation reception unit is invalidated. Since the execution or deactivation of the application is restricted, an erroneous second operation (for example, an erroneous operation of the BACK key) is accepted by the operation accepting unit, and the application is terminated or deactivated and data is lost. There is an effect that can be prevented.
According to the information processing program of claim 4, in addition to the effect of the information processing program of claim 1 or 7, the display of the operation reception display on the display unit is limited, Since the execution of termination or deactivation is limited, there is an effect that it is possible to prevent erroneous operation from being accepted by the operation accepting unit and the application from being terminated or deactivated to lose data.
According to the information processing program of claim 1, 3 or 4, the data created based on the image data passed from the second application is lost when the application is terminated or deactivated. Later, it takes time to recreate the data. At this time, the larger the number of image data passed from the second application, the longer the time required for re-creating the data, and the greater the disadvantage suffered by the user. Therefore, if the number of image data passed from the second application is equal to or greater than a predetermined threshold, the above-mentioned disadvantage of the user is eliminated by setting the condition for terminating the termination or deactivation of this application. There is an effect that can be done. On the other hand, when the number of image data passed from the second application is small, even if the data created based on the image data passed from the second application is lost, the time required for re-creation is compared. It's less expensive. Therefore, when the number of image data passed from the second application is less than a predetermined threshold, by making the above conditions not to be restricted, the user's annoyance that is constrained by the restriction is reduced. There is an effect that can be.

According to the information processing program of the fifth aspect , in addition to the effect produced by the information processing program according to any one of the first to fourth aspects , the following effect is obtained. When the sharing destination application is an image output application (for example, a printing application), it takes time to create the image data of the preview image according to the output setting from the image data passed from the sharing source application However, since loss of data due to erroneous operation of the BACK key is prevented, there is an effect that usability as an image output application is increased.

According to the information processing program of the sixth aspect , in addition to the effect produced by the information processing program according to any one of the first to fifth aspects, the following effect is produced. The larger the data size of the image data passed from the second application, the longer the time required to recreate the data created based on the image data. Therefore, due to the loss of data due to termination or deactivation of this application The disadvantage suffered by the user is also increased. Therefore, when the data size of the image data passed from the second application is equal to or larger than a predetermined threshold, the above-mentioned disadvantage of the user is reduced by setting the condition for restricting the termination or deactivation of this application. There is an effect that it can be solved. On the other hand, when the data size of the image data delivered from the second application is small, even if the data created based on the image data is lost, the time required for re-creation can be relatively short. Therefore, by setting the case where the data size of the image data passed from the second application is less than the predetermined threshold as a condition for not performing the above-described restriction, the user's annoyance that is felt reversely by the restriction is reduced. There is an effect that can be.

According to the information processing program of the seventh aspect , in addition to the effect produced by the information processing program according to any one of the first to sixth aspects, the following effect is obtained. Depending on the format of the image data, for example, there is a format that can include a plurality of pages, such as a PDF format, and a format that needs to be converted into another format by an external device. It takes a relatively long time to create data based on image data. Therefore, when the format of the image data passed from the second application is a format that requires a relatively long time to create the data, the user suffers due to data loss due to termination or deactivation of the application. The disadvantage is also great. Therefore, when the image data passed from the second application is in a predetermined format, the above-described disadvantage of the user can be eliminated by setting the condition for restricting the termination or deactivation of this application. There is. On the other hand, when the image data passed from the second application is in a format other than the predetermined format, it is possible to reduce the user's annoyance that is constrained by the restriction by making the restriction not performed. There is an effect that can be.

According to the information processing program of the eighth aspect , in addition to the effect produced by the information processing program according to any one of the first to seventh aspects, the following effect is obtained. If the data created based on the image data passed from the second application is lost when the image data processing unit is not executing the process, there is a high possibility that the data needs to be recreated. Users are likely to suffer disadvantages. Therefore, by setting the case where the image data processing unit is not executing processing as a condition for restricting the termination or deactivation of this application, the above-described disadvantage of the user can be eliminated. On the other hand, when the image data processing unit executes the process, even if the data created based on the image data passed from the second application is lost, the data has already been achieved. It is likely that you will not need to recreate it. Therefore, by setting the case where the image data processing unit executes the process as a condition that does not perform the above-described restriction, there is an effect that it is possible to reduce the troublesomeness of the user who feels that the restriction is reversed.

According to the information processing program of the ninth aspect , in addition to the effect produced by the information processing program according to any one of the first to seventh aspects, the following effect is obtained. When the operation receiving unit has not received a third instruction that instructs the image data processing unit to execute processing based on image data passed from the second application, the image data passed from the second application If the data created based on the above is lost, there is a high possibility that the data needs to be recreated, so that the user is likely to suffer a disadvantage. Therefore, by setting the case where the operation accepting unit has not accepted the third instruction as a condition for restricting the execution or deactivation of the application, the above-described disadvantage of the user can be solved. On the other hand, when the operation accepting unit accepts the third instruction, even if the data created based on the image data passed from the second application is lost, the purpose has already been achieved. It is likely that the data does not need to be recreated. Therefore, by making the case where the operation accepting unit accepts the third instruction as a condition that does not perform the restriction, there is an effect that it is possible to reduce the troublesomeness of the user who feels that the restriction is reversed.

According to claim 2, wherein the information processing program, in addition to the effects of the information processing program according to claim 1 Symbol placement, before performing the termination or deactivation of the application, be displayed on the display unit Us This restricts the execution of the termination or deactivation, so that the user's intention can be met.

According to the information processing apparatus of the tenth aspect, the same effect as that of the information processing apparatus including the computer that executes the information processing program according to the first aspect is obtained.

According to the information processing method of the eleventh aspect, the same effect as that of the information processing apparatus including the computer that executes the information processing program according to the first aspect is obtained.

  With reference to FIG. 2, a sharing function realized by using the API of the OS 14a of the mobile terminal 10 will be described. The sharing function is a function for causing the application selected as the data output destination to process the data output from the data output source application. Note that the sharing function includes an implicit sharing function and an explicit sharing function. In FIG. 2, the sharing function will be described using the implicit sharing function as a representative example.

  FIG. 2 is a diagram for explaining the implicit sharing function, in which the screen of the data output source application (hereinafter referred to as the sharing source application 60) is in the foreground, that is, the sharing source application 60 is activated. In this state, the flow of processing when the user gives an instruction to start execution of the shared function is shown.

  As shown in FIG. 2, in the implicit sharing function, the sharing source application 60 calls the API of the OS 14a and requests execution of the sharing function (1). This request is executed for the shared data URI (Uniform Resource Identifier) of data (hereinafter shared data) to be processed by another application, the type indicating the format (format) of the shared data, and the shared data. Action indicating the processing to be performed. The URI is information indicating the location of the shared data, and in the case of this embodiment, is configured by a file path. The type is information that specifies the format of the shared data, and the action is information that specifies the type of processing. The OS 14a uses the type and action notified from the sharing source application 60 as search conditions, and selects the data output destination application (hereinafter, referred to as “all applications 62”) from all the applications installed in the mobile terminal 10 (hereinafter, “all applications 62”). Search for candidates that may become the sharing destination application 64) (2).

  Each application installed in the mobile terminal 10 declares in advance a type indicating a format that can be processed by the application and an action indicating the type of processing that can be executed. Therefore, the OS 14a searches for all the applications 62 using the type and action notified from the sharing source application 60 as search conditions. Then, it is possible to process data in the format specified by the type notified from the sharing source application 60, and extract an application corresponding to the type of processing specified by the action notified from the sharing source application 60. Information is acquired (3).

  Next, the OS 14a causes the LCD 18 to display a list of names of applications that are found and extracted by the search, that is, applications that are candidates for the sharing destination application 64 (4). When the user selects one (5), the OS 14a activates the selected sharing destination application 64, and the screen of the sharing destination application 64 is activated in the foreground, that is, the sharing destination application 64 is activated. The status is set, and the URI, type, and action of the shared data notified from the sharing source application 60 are notified (6).

  As a result, the screen of the sharing destination application 64 selected by the user is displayed in the foreground, and the sharing destination application 64 accesses the shared data specified by the notified URI and performs processing according to the action value. For example, various processes that can be executed by the sharing destination application 64, such as display output on the LCD 18 and output to the device 30, are performed.

  The device control application 14b of the present embodiment is activated as a sharing destination application 64 by the above-described implicit sharing function or explicit sharing function from the sharing source application 60 having an image viewer (gallery) function, a mail function, and the like. . For example, after the user selects one or more images as desired from the images displayed on the LCD 18 by the sharing source application 60, the list displayed on the LCD 18 is instructed to start execution of the sharing function. This is activated when the user selects the device control application 14b. Note that the sharing source application 60 is an application stored in the flash memory 14 as another application (not shown).

  Next, referring to FIG. 3, a screen when the screen of the device control application 14 b activated from the sharing source application 60 by the sharing function is displayed in the foreground (when the device control application 14 b is activated). Will be described.

  FIG. 3A shows the preview screen 70. The preview screen 70 displays an image 71 (preview image 71) of preview image data generated in accordance with the print settings stored in the print setting memory 14c based on the image data passed from the sharing source application 60. It is a screen. When the device control application 14b is started from the sharing source application 60 by the sharing function, the device control application 14b calls the API of the OS 14a to display the preview screen 70 on the LCD 18, and the sharing control from the sharing source application 60 therein. A preview image 71 generated based on the image data thus displayed is displayed.

  The preview screen 70 further includes a page display area 72 and a print button 73. The page display area 72 includes the total number of pages of the preview image 71 (that is, the total number of image data passed from the sharing source application 60) and the number of pages of the preview image 71 currently displayed. This is an area for displaying a page number indicating whether the image is a preview image. In the example shown in FIG. 3, “5/8” is displayed in the page display area 72, the total number of pages is “8”, and the page number of the currently displayed preview image 71 is “5”. Indicates.

  The print button 73 is an area for inputting a print function execution instruction to the device 30. When the user touches the print button 73, the device control application 14 b displays print data corresponding to the image data passed from the sharing source application 60 and the print setting stored in the print setting memory 14 c (that is, the preview image 71. The corresponding image print data) is output to the device 30. Specifically, the API of the OS 14 a is called to cause the print data generated by the CPU 11 according to the print settings from the image data delivered from the sharing source application 60 to be output from the wireless LAN transmission / reception unit 15 to the device 30.

  FIG. 3B is a diagram showing the inquiry screen 74. The inquiry screen 74 is a screen on which an inquiry area 75 is displayed. The inquiry screen 74 of the present embodiment is configured as a screen in which an inquiry area 75 is displayed on the front surface in which each part (the preview image 71, the page display area 72, and the print button 73) constituting the preview screen 70 is grayed out.

  The device control application 14b operates such that the BACK key 16a provided on the front surface of the housing 10a is operated (pressed) while the preview screen 70 is displayed in the foreground, and the preview image 71 is not printed. When the predetermined condition is satisfied, the API of the OS 14a is called to switch the screen displayed on the LCD 18 from the preview screen 70 to the inquiry screen 74. In the inquiry screen 74, user operations are accepted only in the inquiry area 75, and user operations are not accepted in the grayed out print button 73.

  The inquiry area 75 is an area for inquiring the user as to whether or not to terminate this application (device control application 14b). The inquiry area 75 displays a message for displaying a message for notifying the user that the preview image 71 has not been printed or that the data (preview image data) of the preview image 71 will be lost if the operation is continued. A region 75c, an OK button 75a, and a cancel button 75b are included.

  The OK button 75a is an area for inputting an instruction to continue processing according to the operation of the BACK key 16a. When the user touches the OK button 75a, the device control application 14b continues the process according to the operation of the BACK key 16a, that is, ends the present application (device control application 14b). Accordingly, the sharing source application 60 that is the immediately preceding application is activated.

  On the other hand, the cancel button 75b is an area for inputting an instruction to cancel the processing according to the operation of the BACK key 16a. When the user touches the cancel button 75b, the device control application 14b cancels the processing according to the operation of the BACK key 16a, calls the API of the OS 14a, and displays a screen to be displayed on the LCD 18 from the inquiry screen 74. Switch to 70.

  By the way, when the device control application 14b is terminated, the work area of the RAM 13 reserved for execution of the device control application 14b is released, so that the created preview image data is highly likely to be lost. When preview image data is lost, even if the device control application 14b is activated again, it is necessary to recreate the preview image data, and accordingly, it is necessary to spend time accordingly. However, as described above, the device control application 14b according to the present embodiment allows the inquiry screen 74 if the predetermined condition is satisfied even if the BACK key 16a is operated while the preview screen 70 is displayed in the foreground. Is displayed on the LCD 18. That is, the device control application 14b displays the inquiry screen 74 once on the LCD 18, thereby limiting the end of the application accompanying the operation of the BACK key 16a. Since the end of the device control application 14b is restricted, the loss of the preview image data created by this application can be prevented. As a result, it is possible to prevent the preview image data from being lost due to an erroneous operation of the BACK key 16a, so that it is possible to suppress the disadvantages (for example, time required for data re-creation) suffered by the user due to the erroneous operation. , Usability as an application increases.

  FIG. 4 is a flowchart showing the shared printing process executed in the mobile terminal 10. This process is started when the device control application 14b is activated when the user selects one or a plurality of images in the sharing source application 60 and then selects the device control application 14b as the sharing destination application 64 by the sharing function. The Note that each step shown in the flowchart of FIG. 4 described below will be described on the assumption that the device control application 14b causes the CPU 11 to execute, or the device control application 14b causes the CPU 11 to execute using a function such as the OS 14a. However, the steps included in each flowchart may be partially replaced with steps that the OS 11a and other applications cause the CPU 11 to execute.

  First, in step S401 (hereinafter, step is omitted), the CPU 11 determines the number of image data passed from the sharing source application 60, that is, the number of images selected by the user in the sharing source application 60 (hereinafter, this number is expressed as “ Is acquired based on the number of URIs ((6) in FIG. 2) of the shared data notified from the sharing source application 60 via the OS 14a (S401). Next, the CPU 11 passes the image data passed from the sharing source application 60, that is, the image data corresponding to the image selected by the user in the sharing source application 60 (hereinafter, this image data is referred to as “shared data”). Is acquired (S402). Specifically, the CPU 11 acquires the shared data path from the shared data URI notified from the sharing source application 60 via the OS 14a.

  Next, the CPU 11 previews based on the image data specified by the acquired shared data path (that is, the image data passed from the sharing source application 60) and the print settings stored in the print setting memory 14c. Image data is created (S403). Next, the CPU 11 sets a print flag (not shown) provided in the RAM 13 to zero (S404). The print flag is a flag indicating whether or not a user has issued a print instruction to the image data passed from the sharing source application 60. Specifically, when the print flag is set to zero, it indicates that the print instruction for the image data passed from the sharing source application 60 has not been issued yet. On the other hand, if the print flag is set to 1, it indicates that a print instruction has already been made for the image data passed from the sharing source application 60.

  Next, the CPU 11 displays the preview screen 70 (FIG. 3A) on the LCD 18 (S405). Next, when there is a print instruction, that is, when the user touches the print button 73 (S406: Yes), the CPU 11 executes a print process (S414). Specifically, the CPU 11 generates print data according to the image data delivered from the sharing source application 60 and the print settings stored in the print setting memory 14c, and the generated print data is transmitted to the wireless LAN transmission / reception unit 15. To the device 30. Receiving this print data, the device 30 prints an image based on the print data on a document by a print function. Next, the CPU 11 sets 1 in the print flag (S415), and the process proceeds to S406.

  On the other hand, when there is no print instruction, that is, when the user does not touch the print button 73 and the BACK key 16a is not operated (pressed) (S406: No, S407: No), the CPU 11 To S406. When there is no print instruction and the BACK key 16a is operated (S406: No, S407: Yes), the CPU 11 determines the number of shared data acquired in S401 (that is, the image passed from the sharing source application 60). It is determined whether or not the number of data is greater than 1 (S408).

  In S408, when the CPU 11 determines that the number of shared data is greater than 1 (S408: Yes), the CPU 11 determines whether 1 is set in the print flag (S409). In S409, when the CPU 11 determines that zero is set in the print flag (S409: No), the inquiry screen 74 (FIG. 3B) is displayed on the LCD 18 (S410).

  Next, when the cancel button 75b of the OK button 75a or the cancel button 75b displayed on the inquiry screen 74 is touched (S411: No), the CPU 11 deletes the inquiry screen 74 displayed on the LCD 18 ( (S412) The preview screen 71 is displayed (S413), and the process proceeds to S406. On the other hand, when the OK button 75a displayed on the inquiry screen 74 is touched (S411: Yes), the CPU 11 ends the processing by this application (device control application 14b). When the CPU 11 determines in S408 that the number of shared data is 1 or less (S408: No), or when the CPU 11 determines in S409 that the print flag is set to 1 (S409: Yes). In addition, the CPU 11 ends the processing by this application.

  As described above, according to the device control application 14b of the present embodiment, even when the BACK key 16a is operated by the user during the execution of the shared printing process activated by the sharing function from the sharing source application 60, the sharing is performed. When the number of data and the setting of the print flag satisfy predetermined conditions, the present application is not terminated and the process of S410 is executed. In other words, the device control application 14b is configured to limit the termination of the application accompanying the operation of the BACK key 16a by displaying the inquiry screen 74 once on the LCD 18 when a predetermined condition is satisfied. Yes. Therefore, even if the BACK key 16a is erroneously operated, the loss of the preview image data due to the termination of this application can be suppressed. Time). Further, whether or not to terminate the application is based on the user's operation on the buttons 75a and 75b displayed on the inquiry screen 74, so that the user's intention can be reflected. Therefore, the device control application 14b of this embodiment has high usability as an application.

  In addition, the device control application 14b has a condition for restricting the end of the application (device control application 14b) when the BACK key 16a is operated by the user. Therefore, even if the BACK key 16a is operated, the inquiry screen 74 is not necessarily displayed on the LCD 18, but conversely by restricting the end of the application (specifically, the inquiry screen 74 is displayed). The user's annoyance can be reduced.

  In particular, the device control application 14b uses the number of shared data, that is, the number of image data passed from the sharing source application 60 as a condition for whether or not to limit the end of the application. The greater the number of image data delivered from the sharing source application 60, the longer the time required for creating the preview image data, and the greater the disadvantage that the user suffers when the preview image data is lost. On the other hand, if the number of image data passed from the sharing source application 60 is small to some extent, even if the preview image data is lost, the user suffers relatively little disadvantage, and rather, the display of the inquiry screen 74 seems to be troublesome. Probability is high. Therefore, by setting the number of shared data as a condition for limiting the termination of the application, it is possible to further improve the usability as an application while eliminating the disadvantage of the user due to an erroneous operation.

  In addition, the device control application 14b sets a print flag (not shown) provided in the RAM 13, that is, whether or not a print instruction is issued by the user as a condition for limiting the end of the application. . If the user has not issued a print instruction (that is, if the print flag is set to zero), the device 30 naturally does not print an image based on the image data passed from the sharing source application 60. When the preview image data is lost, there is a high possibility that the preview image data needs to be recreated. Therefore, when the preview image data is lost, the user is likely to suffer a disadvantage. On the other hand, when the user gives a print instruction (that is, when the print flag is set to 1), even if the preview image data is lost, the purpose of printing has already been achieved. There is a high possibility that there is no need to re-create, and rather, it is highly likely that the display of the inquiry screen 74 is troublesome. Therefore, by setting the print flag as a condition for limiting the end of the application, it is possible to further improve the usability as an application while eliminating the disadvantage of the user due to an erroneous operation.

  Next, a second embodiment will be described with reference to FIG. In the first embodiment described above, the device control application 14b is configured to limit the end of the application by displaying the inquiry screen 74 on the LCD 18 when the BACK key 16a is operated. Then, by invalidating the BACK key 16a, the application is restricted from being terminated when the BACK key 16a is operated. FIG. 5 is a flowchart illustrating the shared printing process according to the second embodiment. The device control application 14b of the second embodiment is different from the first embodiment in that the CPU 11 executes the shared printing process shown in FIG. 5 instead of the shared printing process (FIG. 4) of the first embodiment. Are the same. Of the shared printing process shown in FIG. 5, the same parts as those in the shared printing process (FIG. 4) of the first embodiment are denoted by the same step numbers and the description thereof is omitted.

  In the shared printing process of the second embodiment, first, the CPU 11 invalidates the BACK key 16a (S501). Next, the CPU 11 executes the processes of S401 to S403 and S405 as in the first embodiment.

  Next, the CPU 11 determines whether or not the number of shared data acquired in S401 (that is, the number of image data passed from the sharing source application 60) is greater than 1 (S502). In S502, when the number of shared data is 1 or less (S502: No), the CPU 11 validates the BACK key 16a (S503), and the process proceeds to S406. On the other hand, if the number of shared data is greater than 1 in S502 (S502: Yes), the CPU 11 skips the process of S503 and proceeds to S406.

  Next, when there is a print instruction (S406: Yes), the CPU 11 executes print processing (S414). After the process of S414, the CPU 11 validates the BACK key 16a (S504), and returns the process to S406. On the other hand, when there is no print instruction and the BACK key 16a is not operated (pressed) (S406: No, S407: No), the CPU 11 returns the process to S406.

  On the other hand, when there is no print instruction and the BACK key 16a is operated (S406: No, S407: Yes), the CPU 11 ends the process by this application. As described above, the device control application 14b according to the second embodiment disables the BACK key 16a by the processing of S501. Therefore, the user operates the BACK key 16a unless the processing of S503 or S504 is executed. However, since the operation is invalidated, it is determined No in S407. Then, when the BACK key 16a is validated by the processing of S503 or S504, it is determined Yes in S407 when the BACK key 16a is operated.

  According to the device control application 14b of the second embodiment, since the BACK key 16a is invalidated in the shared printing process activated by the sharing function from the sharing source application 60, even if the BACK key 16a is operated, The operation is invalidated and this application is configured not to end. That is, the device control application 14b according to the second embodiment is configured to limit the end of the present application (device control application 14b) accompanying the operation of the BACK key 16a by invalidating the BACK key 16a. On the other hand, by enabling the disabled BACK key 16a, conditions are provided so as not to limit the termination of this application, so that the number of shared data is small, a print instruction is given, etc. Even if image data is lost, if the user suffers relatively little disadvantage, the BACK key 16a is configured to be activated so that the end of the application is restricted and the user feels the opposite. Can be reduced. Therefore, the usability as an application can be further improved while eliminating the disadvantage of the user due to an erroneous operation.

  Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. Can be inferred.

  For example, in the above-described embodiment, the mobile terminal 10 having a call function is an example of an information processing apparatus. However, various apparatuses that do not have a call function such as a personal computer and a digital camera are examples of the information processing apparatus. obtain. Further, the present invention can be applied to a device that does not have the touch panel 17 and inputs an operation from a hardware key.

  In the above embodiment, the OS 14a has been described as an Android OS. However, the present invention can be applied to an information processing apparatus equipped with another OS.

  In the above embodiment, the sharing function is described as being realized by the OS 14a, but the present invention can be applied to the case where the sharing function is realized by hardware or middleware instead.

  Further, in the above embodiment, the mobile terminal 10 and the device 30 are described as being connected by Wi-Fi, but instead, for example, when connected by Bluetooth (registered trademark), The present invention is applicable.

  In the above embodiment, the BACK key 16a, which is a hardware key, has been described as a key for terminating the device control application 14b activated from the sharing source application 60. However, the function of the BACK key 16a is displayed on the LCD 18. It is good also as a structure given to a button. That is, the device control application 14b displays a button to which the function of the BACK key 16a is assigned (hereinafter referred to as “BACK button”) in the preview screen 71 displayed on the LCD 18, and the BACK button is touched. In this case, the present application (device control application 14b) may be terminated. As described above, when the BACK button is displayed in the preview screen 71 displayed on the LCD 18, even if the BACK button is touched, the setting of the number of shared data and the setting of the print flag satisfies predetermined conditions. In such a case, the inquiry screen 74 may be displayed to limit the end of the application (that is, as in the first embodiment). Further, when a BACK button is displayed in the preview screen 71 displayed on the LCD 18, a user operation such as graying out the BACK button is accepted under a predetermined condition as in the second embodiment. It may be configured to limit the end of the application by making it not.

  Further, when the BACK button is configured to be displayed in the preview screen 71 displayed on the LCD 18, it is configured to limit the end of the application by not displaying the BACK button on the LCD 18 under a predetermined condition. May be. For example, in the shared printing process of FIG. 5, when displaying the preview screen 71 on the LCD 18 in S405, the CPU 11 does not display the BACK button in the preview screen 71, and the BACK in the processes of S503 and S504. Instead of the process of enabling the key 16, a BACK button may be displayed in the preview screen 71.

  In the above embodiment, the end of the device control application 14b is restricted when the number of shared data is greater than 1 or when the print flag is set to zero (that is, when a print instruction is issued). However, instead of this, or in addition to this, other cases may be used as conditions for restricting termination of the device control application 14b.

  For example, when the data size of the shared data (image data passed from the shared application 60) is set as a condition for restricting the end of the device control application 14b, the device control is performed when the total data size of the shared data is equal to or larger than a predetermined size. You may comprise so that completion | finish of the application 14b may be restrict | limited. Alternatively, the end of the device control application 14b may be limited when at least one shared data has a predetermined size or more. The larger the data size of the shared data, the longer the time required for re-creating the preview image data. Therefore, the disadvantage suffered by the user when the preview image data is lost increases. On the other hand, if the data size of the shared data is small to some extent, even if the preview image data is lost, the disadvantage suffered by the user is relatively small, rather, the termination of the device control application 14b is restricted. There is a high possibility of feeling annoying. Therefore, when the data size of the shared data is set as a condition for limiting the termination of the application accompanying the operation of the BACK key 16a, the same advantages as those in the above embodiment can be provided.

  As another example, when the format of the shared data (image data passed from the shared application 60) is a condition for restricting the end of the device control application 14b, and the shared data has a predetermined format, the device control application You may comprise so that completion | finish of 14b may be restrict | limited. For example, when the format of the shared data is a format that can include a plurality of pages, such as a PDF format or a TIFF format, the preview image data for a plurality of pages is re-created when the preview image data is lost. Can take a long time, which can be detrimental to the user. On the other hand, when the format of the shared data is a format in which one image data becomes one file, such as JPEG format or GIF format, even if the preview image data is lost, there is little disadvantage to the user. Rather, there is a high possibility that the end of the device control application 14b will be restricted and the user will feel bothered. Or, depending on the specifications of the mobile terminal, image data in some formats (for example, PDF format) cannot be displayed on the LCD, but can be displayed on the LCD using an external server or cloud. Some of them are converted into another format (for example, JPEG format). Since the conversion of the format using an external server or cloud requires a waiting time for the conversion, the loss of the preview image data created from the image data of the format after conversion gives a great disadvantage to the user. Therefore, when the format of the shared data is a format that needs to be converted using an external server or cloud, it is possible to provide high usability by restricting termination of the device control application 14b. it can. On the other hand, if the format of the shared data is a format that does not need to be converted using an external server or cloud, even if the preview image data is lost, the disadvantage suffered by the user is compared. Rather, there is a high possibility that the end of the device control application 14b will be restricted. Therefore, also when the format type of the shared data is set as a condition for limiting the termination of the application accompanying the operation of the BACK key 16a, the same advantages as in the above embodiment can be provided.

  In the above embodiment, the setting of the print flag provided in the RAM 13, that is, whether or not the user has issued a print instruction, and whether or not to limit the end of the application in accordance with the operation of the BACK key 16 a, did. Instead, when the print data is not output to the device 30 via the wireless LAN transmission / reception unit 15, the termination of the application accompanying the operation of the BACK key 16a is restricted, and at least a part of the print data (for example, When at least one page of a plurality of pages) is output to the device 30 via the wireless LAN transmission / reception unit 15, the application may be terminated in accordance with the operation of the BACK key 16a. . Alternatively, only when all of the print data is output to the device 30 via the wireless LAN transmission / reception unit 15, the application is terminated in accordance with the operation of the BACK key 16a, and at least a part of the print data is When the data is not output to the device 30 via the wireless LAN transmission / reception unit 15, the end of the application accompanying the operation of the BACK key 16a may be limited. In such a case, the restriction mode when no print data is output may be different from the restriction mode when only a part of the print data is output. For example, the content of the inquiry screen 74 displayed on the LCD 18 may be changed between when no print data is output and when only a part of the print data is output.

  In the above embodiment, whether or not the user has issued a print instruction is set as a condition for whether or not to terminate the application accompanying the operation of the BACK key 16a, but the image data passed from the sharing source application 60 Whether or not the preview image data created based on the above is output for display on an external device (or whether or not an instruction has been given), or whether or not the preview image data is output for storage in an external device (or Whether or not an instruction for that is given) may be used as a condition for restricting termination of the application accompanying the operation of the BACK key 16a. For example, when preview image data created based on image data passed from the sharing source application 60 is not output for display on an external device, the termination of the application associated with the operation of the BACK key 16a is restricted and created. If the preview image data thus output is output for display on an external device, the application may be terminated in accordance with the operation of the BACK key 16a.

  In the above embodiment, the application (device control application 14b) is terminated without deleting the preview image data. However, the preview image data may be deleted before the application is terminated.

  In the above embodiment, the device control application 14b is terminated in accordance with the operation of the Back key 16a. Instead of such a configuration, the present invention may be applied to a configuration in which the device control application 14b is in the background state and the sharing source application is in the foreground state in accordance with the operation of the Back key 16a. When the sharing source application enters the foreground state, the RAM area reserved for the background state application may be released for the OS 14a and other applications. Therefore, the present invention is effective for such a configuration. Note that the background state is an example of deactivation.

  In the above embodiment, when the BACK key 16a provided on the front surface of the housing 10a is operated with the preview screen 70 displayed in the foreground and a predetermined condition is satisfied, the device control application 14b is The screen of the OS 14a is called and the screen displayed on the LCD 18 is switched from the preview screen 70 to the inquiry screen 74. Instead of this, in the above case, the device control application 14b may be configured to call the API of the OS 14a and display on the LCD 18 a screen in which the preview screen 70 and the inquiry screen 74 are combined. Alternatively, in the above case, the device control application 14b may be configured to call the API of the OS 14a and additionally display the inquiry screen 74 on the preview screen 70 being displayed on the LCD 18.

  In the above embodiment, when the user touches the cancel button 75b, the device control application 14b calls the API of the OS 14a to switch from the inquiry screen 74 to the preview screen 70. Alternatively, in the above case, the device control application 14b may be configured to display the preview screen 70 by calling the API of the OS 14a. Alternatively, in the above case, the device control application 14b may be configured to call the API of the OS 14a and delete the inquiry screen 74 displayed on the preview screen 70 being displayed on the LCD 18.

  In the above embodiment, in S403 of the shared printing process (FIGS. 4 and 5), the CPU 11 is based on the image data passed from the sharing source application 60 and the print settings stored in the print setting memory 14c. The configuration is such that preview image data is created. Alternatively, in S403, the CPU 11 may create print data equivalent to that created in S414 and create preview image data to be displayed on the LCD 18 based on the created print data. Alternatively, in S403, the CPU 11 generates print data equivalent to that created in S414, and in S405, the CPU 11 displays the print data created in S403 on the LCD 18 using the API of the OS 14a. May be. That is, the print data may also be configured to serve as preview image data.

  In the shared printing process (FIG. 5) of the second embodiment, the print flag used in the shared printing process (FIG. 4) of the first embodiment is not used, that is, the processes of S404 and S415 are omitted. Instead of this, a print flag may be used in the shared printing process of the second embodiment. In other words, the shared printing process of the second embodiment may be configured to execute the processes of S404 and S415 similarly to the shared printing process of the first embodiment. In this case, for example, in the shared printing process of the second embodiment, if the process of S504 is omitted and the BACK key 16a is operated (S407: Yes), the first flag is set if the print flag is set to 1. Similarly to the embodiment, the inquiry screen 74 may be displayed on the LCD 18 (that is, the process of S410 is executed). In other words, as a configuration for suppressing the disadvantage suffered by the user due to an erroneous operation of the BACK key 16a, the activation of the BACK key 16a and the display of the inquiry screen 74 may be mixed.

  In the above embodiment, the telephone network communication unit 22 is connected to the Internet (not shown) via the mobile phone network 100 so that the mobile terminal 10 can use the Internet. Instead, the wireless LAN receiving unit 15 may connect to the Internet (not shown) via the access point 50 having a broadband router function so that the mobile terminal 10 can use the Internet.

  Moreover, you may employ | adopt embodiment which combined the characteristic of the said 1st Embodiment and 2nd Embodiment, and the characteristic of the said modification suitably.

<Effect>
According to the information processing program of the technical idea 1, when the display unit displays an image, even if the operation receiving unit receives a second operation (for example, operation of the BACK key), the application is terminated. Alternatively, since restrictions are placed on deactivation, each data created by the application can be prevented from being lost when the application is terminated or deactivated. Thereby, it is possible to prevent data loss due to a second operation (for example, an erroneous operation of the BACK key) that is erroneously performed. Therefore, there is an effect that it is possible to improve the usability as an application by eliminating the disadvantage of the user due to an erroneous operation, such as the need to re-create data that requires time.
According to the information processing program of the technical idea 2, in addition to the effect produced by the technical idea 1, the following effect is produced. When the sharing destination application is an image output application (for example, a printing application), it takes time to create the image data of the preview image according to the output setting from the image data passed from the sharing source application However, since loss of data due to erroneous operation of the BACK key is prevented, there is an effect that usability as an image output application is increased.
According to the information processing program of the technical idea 3, in addition to the effect produced by the technical idea 1 or 2, the following effect is produced. Of course, it takes time to re-create the data created based on the image data passed from the second application after the data is lost when the application is terminated or deactivated. At this time, the larger the number of image data passed from the second application, the longer the time required for re-creating the data, and the greater the disadvantage suffered by the user. Therefore, if the number of image data passed from the second application is equal to or greater than a predetermined threshold, the above-mentioned disadvantage of the user is eliminated by setting the condition for terminating the termination or deactivation of this application. There is an effect that can be done. On the other hand, when the number of image data passed from the second application is small, even if the data created based on the image data passed from the second application is lost, the time required for re-creation is compared. It's less expensive. Therefore, when the number of image data passed from the second application is less than a predetermined threshold, by making the above conditions not to be restricted, the user's annoyance that is constrained by the restriction is reduced. There is an effect that can be.
According to the information processing program of technical idea 4, in addition to the effect produced by any of technical ideas 1 to 3, the following effect is produced. The larger the data size of the image data passed from the second application, the longer the time required to recreate the data created based on the image data. Therefore, due to the loss of data due to termination or deactivation of this application The disadvantage suffered by the user is also increased. Therefore, when the data size of the image data passed from the second application is equal to or larger than a predetermined threshold, the above-mentioned disadvantage of the user is reduced by setting the condition for restricting the termination or deactivation of this application. There is an effect that it can be solved. On the other hand, when the data size of the image data delivered from the second application is small, even if the data created based on the image data is lost, the time required for re-creation can be relatively short. Therefore, by setting the case where the data size of the image data passed from the second application is less than the predetermined threshold as a condition for not performing the above-described restriction, the user's annoyance that is felt reversely by the restriction is reduced. There is an effect that can be.
According to the information processing program of the technical idea 5, in addition to the effect produced by any of the technical ideas 1 to 4, the following effect is produced. Depending on the format of the image data, for example, there is a format that can include a plurality of pages, such as a PDF format, and a format that needs to be converted into another format by an external device. It takes a relatively long time to create data based on image data. Therefore, when the format of the image data passed from the second application is a format that requires a relatively long time to create the data, the user suffers due to data loss due to termination or deactivation of the application. The disadvantage is also great. Therefore, when the image data passed from the second application is in a predetermined format, the above-described disadvantage of the user can be eliminated by setting the condition for restricting the termination or deactivation of this application. There is. On the other hand, when the image data passed from the second application is in a format other than the predetermined format, it is possible to reduce the user's annoyance that is constrained by the restriction by making the restriction not performed. There is an effect that can be.
According to the information processing program of technical idea 6, in addition to the effect produced by any of technical ideas 1 to 5, the following effect is produced. If the data created based on the image data passed from the second application is lost when the image data processing unit is not executing the process, there is a high possibility that the data needs to be recreated. Users are likely to suffer disadvantages. Therefore, by setting the case where the image data processing unit is not executing processing as a condition for restricting the termination or deactivation of this application, the above-described disadvantage of the user can be eliminated. On the other hand, when the image data processing unit executes the process, even if the data created based on the image data passed from the second application is lost, the data has already been achieved. It is likely that you will not need to recreate it. Therefore, by setting the case where the image data processing unit executes the process as a condition that does not perform the above-described restriction, there is an effect that it is possible to reduce the troublesomeness of the user who feels that the restriction is reversed.
According to the information processing program of the technical idea 7, in addition to the effect produced by any of the technical ideas 1 to 5, the following effect is produced. When the operation receiving unit has not received a third instruction that instructs the image data processing unit to execute processing based on image data passed from the second application, the image data passed from the second application If the data created based on the above is lost, there is a high possibility that the data needs to be recreated, so that the user is likely to suffer a disadvantage. Therefore, by setting the case where the operation accepting unit has not accepted the third instruction as a condition for restricting the execution or deactivation of the application, the above-described disadvantage of the user can be solved. On the other hand, when the operation accepting unit accepts the third instruction, even if the data created based on the image data passed from the second application is lost, the purpose has already been achieved. It is likely that the data does not need to be recreated. Therefore, by making the case where the operation accepting unit accepts the third instruction as a condition that does not perform the restriction, there is an effect that it is possible to reduce the troublesomeness of the user who feels that the restriction is reversed.
According to the information processing program of the technical idea 8, in addition to the effect produced by any of the technical ideas 1 to 7, an inquiry display is displayed on the display unit before the application is terminated or deactivated. This restricts the execution of the termination or deactivation, so that the user's intention can be met.
According to the information processing program of the technical idea 9, in addition to the effect produced by any of the technical ideas 1 to 7, the reception of the second operation by the operation reception unit is disabled, thereby terminating or not Since the execution of activation is limited, an effect of preventing an erroneous second operation (for example, an erroneous operation of the BACK key) from being accepted by the operation accepting unit and ending or deactivating the application is lost. There is.
According to the information processing program of the technical idea 10, the application is terminated or deactivated by restricting the display of the operation acceptance display on the display unit in addition to the effect produced by the technical idea 1 or 7. Therefore, there is an effect that it is possible to prevent an erroneous operation from being accepted by the operation accepting unit and ending or deactivating the application to lose data.
