  The present invention relates to an application program and an arithmetic processing device, and more particularly to an application program and an arithmetic processing device that notify that when normal processing is not executed.

  For example, Patent Document 1 below proposes a mobile phone that is controlled to reduce power consumption. Specifically, this mobile phone includes a touch panel, and when there is no input to the touch panel, the mobile phone shifts to a so-called sleep mode that reduces power consumption in the mobile phone, and input to the touch panel is performed. Shifts to the normal mode in which the power consumption increases.

  Some mobile phones can install various application programs. For example, it is a program for causing a mobile phone to realize a function for outputting image data from a mobile phone to a printer and recording an image represented by the image data on a recording sheet by the printer.

JP 2010-238078 A

  By the way, when the target process is not normally executed by the mobile phone, the application program normally notifies the user that the error has occurred by displaying on the display screen that an error has occurred. . However, for example, when shifting to the sleep mode with the error display being displayed in the normal mode, the inventors have a phenomenon that the error display is deleted from the display screen when shifting from the sleep mode to the normal mode. confirmed. In this case, for example, when the mobile phone shifts to the sleep mode without noticing the error display, there is a problem that the user has no opportunity to confirm the error display.

  The present invention has been made in the process of solving the above problems, and an object thereof is to provide an application program and an arithmetic processing unit capable of appropriately displaying the fact when normal processing is not executed. It is in.

  In order to achieve this object, the application program of the present invention is one of a plurality of programs executed by hardware means including a display unit, and has a predetermined function as a function to be executed by the hardware means. A display function for displaying that the display unit is not normally executed when the process is not normally executed, a detection function for detecting that the display displayed by the display function is deleted, and deletion by the detection function And a re-display function for re-displaying on the display section that the operation has not been performed normally.

  Moreover, the arithmetic processing apparatus of this invention is provided with the display part and the control part, The said control part displays that the said display part is not performed normally, when a predetermined | prescribed process is not normally performed. The display means, a detection means for detecting that the display has been deleted when the display function is executed, and the fact that the display function is not normally executed on condition that the deletion is detected by the detection function. Redisplay means for displaying again on the display unit.

  In the application program according to claim 1, when the display is unintentionally deleted even though the display by the display function is not intentionally deleted by providing the detection function, This can be grasped. If it is known that the display has been deleted unintentionally, even if the display indicating that the display is not executed normally is deleted by the redisplay function, the display indicating that the display is not executed normally is displayed again. Can do. For this reason, when a predetermined process is not normally performed, the fact can be appropriately displayed to the user.

  Since the application program according to claim 2 has a program for executing an energy saving control function having a sleep transition function and a normal transition function, the display on the display unit is not confirmed or perceived by the user in the sleep mode state. Tend to. For this reason, when the predetermined process is not normally executed in the sleep mode state, it is particularly desired to display that the normal process is not executed when the normal mode is entered. Therefore, in the application program according to claim 2, the utility value of the application program according to claim 1 is particularly great.

  In the application program according to claim 3, since the indication that the program is not executed normally can be deleted when shifting to the normal mode, in addition to the effect of the application program according to claim 2, the utility value of the redisplay function is particularly It has the feature of being large.

  In the application program according to the fourth aspect, attention is paid to the fact that the user is highly likely to confirm the display unit when shifting to the normal mode. That is, if redisplay is performed by shifting to the normal mode, the user is highly likely to confirm the contents. Whether or not this possibility is particularly high can be grasped by the prescribed number of times. In view of this point, after specifying a situation in which it is determined that the user has confirmed that the display is not executed normally by the specified number of times, the re-display restriction function restricts the re-display. Thereby, according to the application program according to claim 4, in addition to the effect of the application program according to any one of claims 1 to 3, it is possible to avoid a situation where unnecessary re-display is performed. There is an effect that can be done.

  The application program according to claim 5 is not executed normally in addition to the effect of the application program according to any one of claims 1 to 4 due to an organic combination of the continuation permission determination function and the redisplay function. When the situation has been resolved, an effect is obtained that it is possible to avoid a situation where a re-display indicating that the operation is not normally performed is performed.

  In the application program according to the sixth aspect of the present invention, attention is paid to the fact that when a situation that does not execute normally occurs, the situation can change with the passage of time. In view of this point, according to the application program according to claim 6, according to the application program according to claim 6, the content of the redisplay is made different depending on whether the elapsed time determination means determines that the time is not less than the specified time. In addition to the effect of the application program described in any one of the above, there is an effect that appropriate re-display can be performed according to a change in the situation.

  In the application program according to the seventh aspect, when the display is deleted by the user's instruction, the process of redisplaying is not executed. Thus, in addition to the effect of the application program according to any one of claims 1 to 6, it is possible to avoid a situation in which the user thinks that the process according to the instruction is not performed.

  In the application program according to the eighth aspect, it is determined whether or not to perform redisplay according to the type of the state that is not normally executed. Therefore, in addition to the effect of the application program according to any one of claims 1 to 7, it is determined whether or not to execute redisplay depending on whether or not redisplay is desirable. You can choose.

  In the application program according to claim 9, when an image cannot be recorded while a part of the image obtained from the image data transmitted from the transmission function is recorded by the recording device, the situation is overcome. Note that it is especially important to prompt the user. In view of this point, by setting the redisplay execution condition, the application program according to claim 7 can surely display the defect to be notified to the user in addition to the effect of the application program according to claim 8. There is an effect that can be.

  The arithmetic processing unit according to claim 10 includes the detection unit, and the display by the display unit is deleted unintentionally even though the display by the application program is not intentionally deleted. Can figure this out. If it is known that the display has been deleted unintentionally, the display means that the display is not executed properly even if the display indicating that the display is not executed normally is deleted. Can do. For this reason, when a predetermined process is not normally performed, the fact can be appropriately displayed to the user.

  Hereinafter, an embodiment according to the present invention will be described with reference to the drawings.

  FIG. 1 shows a configuration of a mobile phone 10 according to the present embodiment. As illustrated, the mobile phone 10 includes a central processing unit (CPU 14), a memory 16, a communication unit 18, and a user interface 20, which can communicate with each other via the input / output port 12. The CPU 14 is a hardware processing unit that executes a program stored in the memory 16. These programs include a printing application program (printing application Pb) that communicates with the operation system Pa and an apparatus having an external printing function. These programs are preferably stored in a non-volatile memory, such as a flash memory, which is a rewritable memory that stores and holds data regardless of whether power is supplied or not. This can be realized by providing the memory 16 with a nonvolatile memory. In the present embodiment, “Windows Phone (registered trademark)” is assumed as the operation system Pa. On the other hand, in this embodiment, the user interface 20 includes image display means such as a liquid crystal display (LCD) and a so-called touch panel that allows a user to perform an input operation on the image display area of the image display means. ing. This can be realized, for example, by superposing a touch panel on the LCD.

  The operation system Pa has a function of causing the CPU 14 to execute a process of shifting to a sleep mode that reduces power consumption in the mobile phone 10 with respect to the normal mode on condition that the user does not operate the mobile phone 10. . In the sleep mode, as shown in FIG. 2, for example, the image display function that is the output function of the user interface 20 is stopped, while the state in which the user can perform an input operation is maintained. Here, the stop of the image display function in the present embodiment means that display processing is not performed, for example, that the image display means is an LCD, and the backlight emission and the liquid crystal drive are stopped.

  On the other hand, when the print application Pb is executed by the CPU 14, communication processing between the multi-function peripheral device (MFP 30) having the print function shown in FIG. 3 and the mobile phone 10 is executed. The print application Pb causes the CPU 14 to execute a function of outputting image data from the mobile phone 10 to the MFP 30 and outputting a command for recording the image represented by the image data on the recording paper from the mobile phone 10 to the MFP 30. Further, if an error occurs in which the instruction issued to the MFP 30 via the mobile phone 10 is not executed, the print application Pb displays this on the user interface 20 of the mobile phone 10 to indicate that the user has an error. The CPU 14 is caused to execute the notification function.

  By the way, when image data is transmitted from the cellular phone 10 in accordance with a user instruction and the MFP 30 records an image represented by the image data on a recording sheet, it takes time from reception of the user instruction to recording of the image. For this reason, when the recording process is performed, the user does not need to perform an input operation on the mobile phone 10, and thus the mobile phone 10 may be left away from the user's hand. In this case, the state where the user does not perform an input operation to the user interface 20 may continue, and the operation system Pa may shift to the sleep mode. For this reason, the process that the print application Pb should cause the CPU 14 to execute is not normally executed, and the print application Pb may cause an error display on the user interface 20 and then shift to the sleep mode. In this case, if an error is displayed on the user interface 20 by shifting from the sleep mode to the normal mode in accordance with the user's input operation, the user can know the error.

  However, the inventors found a phenomenon in which the error display realized by the CPU 14 executing the printing application Pb is deleted along with the shift to the normal mode. When the error display is deleted, the user cannot be notified of the error via the user interface 20. Incidentally, it is considered that the subject that deletes the error display is the operation system Pa. This is because it is usually impossible for another application program to access the printing application Pb.

  Therefore, in the present embodiment, such a situation is dealt with by causing the CPU 14 to execute the following functions by the print application Pb.

  FIG. 4 shows a procedure of error display processing according to the present embodiment. This process is repeatedly executed at a predetermined cycle, for example, by the print application Pb being executed by the CPU 14. In addition, the process shown in FIG. 4 comprises a display function in this embodiment.

  In this series of processing, the CPU 14 first determines in step S10 whether or not a displayed flag indicating that an error has been displayed on the user interface 20 is ON. If the determination is negative in step S10, the CPU 14 determines whether an error has occurred in step S12. If the CPU 14 determines that an error has occurred in step S12, the CPU 14 causes the user interface 20 to display the error in step S14. In the present embodiment, an error is additionally displayed on the main screen displayed in the image display area of the user interface 20 in particular. For example, the display of the error is realized by displaying a pop-up screen indicating the error in the display area. This processing corresponds to the display function in the present embodiment. In step S14, the CPU 14 turns on the displayed flag. Further, in step S14, after the error display is deleted by the operation system Pa, the CPU 14 initializes a flag (redisplayed flag) indicating that the error display is redisplayed.

  On the other hand, when making a positive determination in step S10, the CPU 14 determines whether or not the error has been resolved in step S16. If the CPU 14 makes a negative determination in step S16, the CPU 14 measures the time during which an error has occurred in step S18. On the other hand, when an affirmative determination is made in step S16, the CPU 14 deletes the error display in step S20, initializes the displayed flag, and initializes the time measurement result in the process in step S18.

  Note that the CPU 14 once ends the series of processes when the processes of steps S14, S18, and S20 are completed or when a negative determination is made in step S12.

  FIG. 5 shows a procedure of error redisplay processing according to the present embodiment. This process is performed by the CPU 14 executing the print application Pb. Moreover, this process is repeatedly performed, for example with a predetermined period.

  In this series of processes, the CPU 14 first determines whether or not the displayed flag is on in step S30. If the determination in step S30 is affirmative, the CPU 14 determines in step S32 whether or not deletion of the error display is instructed by an input operation to the user interface 20 by the user. If the CPU 14 makes a positive determination in step S32, it deletes the error display in step S34. That is, the error display as a pop-up display is deleted while leaving the main screen displayed in the image display area of the user interface 20. This process is actually executed by the operation system Pa in response to a request from the print application Pb. In step S34, the CPU 14 initializes the displayed flag and initializes the time measurement result obtained in step S18.

  In contrast, if the CPU 14 makes a negative determination in step S32, it determines whether or not the error display has been deleted in step S36. This process is for determining whether or not the error display by the user interface 20 has been deleted by an unintended process for the print application Pb. In this process, when an error display is deleted, in a storage area for storing the fact, whether or not there is a write indicating that the error display has been deleted is obtained through a dedicated API (Application Programming Interface). Done. In addition, the process of step S36 comprises a detection function in this embodiment.

  If the CPU 14 makes an affirmative determination in step S36, it determines in step S38 whether or not the type of error in the deleted error display is a fatal error. Here, the fatal error is an error. The error is likely to cause the inconvenience such as the possibility that the user is not aware of the error at the timing and the transmission data may be lost if the error is left unattended. This is the case, for example, when an error occurs during the recording operation of the MFP 30. In this case, for example, when the image data received by the mobile phone 10 is transmitted to the MFP 30, the user may lose the image data by deleting the image data from the mobile phone 10 without noticing the error. is there. For example, when the PDF data file is output from the mobile phone 10 to the MFP 30 and the image represented by the PDF data file is recorded on the recording paper in the MFP 30, the PDF data file cannot be converted from the middle and forms an image. This occurs when processing cannot be performed. Incidentally, when all of the PDF data file cannot be converted into an image, an error is displayed immediately in response to the user's operation, and thus the user is likely to notice the error display. For this reason, in this embodiment, such an error is not regarded as a fatal error.

  CPU14 performs the process of step S38 based on the table which the printing application Pb memorize | stores. As shown in FIG. 6, this table stores information on the importance of displaying for each type of error that may occur during execution of the printing application Pb. Here, when the importance is “high”, it means a fatal error, and when it is “low”, it means that the importance is not a fatal error. FIG. 6 illustrates, as a fatal error, a case where ink runs out during recording an image on a recording sheet, in other words, a case where ink runs out during printing, in addition to those described above. did.

  When the CPU 14 makes an affirmative determination in step S38, in step S40, the CPU 14 stores the type of error in an area of the memory 16 that stores the contents to be redisplayed for errors. In the subsequent step S42, the CPU 14 determines whether or not a request for starting image display on the user interface 20 is generated with the transition from the sleep mode to the normal mode, in other words, whether or not there is a page display request. This processing is actually performed by grasping whether a page display request is written in a storage area for storing the page display request through a dedicated API. If the determination in step S42 is affirmative, the CPU 14 determines in step S44 whether or not the redisplayed flag is on. Here, when this processing is reached for the first time after an error occurs, the redisplayed flag is off. This is because the redisplayed flag is initialized by the process of step S14 of FIG. 4 at the stage where an error occurs.

  When making a negative determination in step S44, the CPU 14 determines whether or not the error has been resolved in step S46. This process is for determining whether or not the error has been resolved between the time when the affirmative determination is made in step S30 and the time when this process is reached. If the determination in step S46 is negative, the CPU 14 determines in step S48 whether or not the error duration time measured by the process in step S18 of FIG. 4 is equal to or greater than the threshold value Tth. This process is for determining whether it is better to change the error display contents between the time point when the error display is given by the process of step S14 of FIG. 4 and the current time point.

  If the CPU 14 makes a negative determination in step S48, in step S50, the CPU 14 displays the same error content as in step S14 in FIG. On the other hand, if the CPU 14 makes an affirmative determination in step S48, based on the type of error stored in step S40 in step S52, the error differs in content from the error display in step S14 in FIG. Display. Here, the error display displayed in step S52 is the same as the error display displayed in step S14, but the error type display is the same, but from the time point when the process of step S14 in FIG. 4 is performed. This reflects the change in error contents. Specifically, for example, a procedure for eliminating an error or contents indicating that an error has passed for a long time may be added. However, if the error content has not changed, the error content may be displayed in the same manner as in step S14 of FIG.

  When the processes in steps S50 and S52 are completed, the CPU 14 turns on the error redisplayed flag in step S54. In addition, the process of step S50, S52 comprises the redisplay function in this embodiment. In step S56, the CPU 14 erases the error content stored by the process in step S40.

  Since the CPU 14 performs such a process, after that, when the determination process of step S44 is performed by shifting again to the sleep mode and then shifting to the normal mode, an affirmative determination is made, so that the error is restored. No display is made. In addition, the process of step S44 comprises a redisplay restriction | limiting function in this embodiment.

  The CPU 14 terminates the series of processes once when the processes of steps S34 and S56 are completed, when a negative determination is made in the processes of steps S36 and S38, and when an affirmative determination is made in steps S44 and S46. To do.

  According to the embodiment described above, the following effects can be obtained.

  (1) When the printing application Pb itself has not deleted the error display, the storage area where the error display has been deleted is accessed via the API, and whether or not the error display has been deleted. Was detected. Thereby, it is possible to grasp when the display is deleted unintentionally even though the error display is not deleted by the printing application Pb. Furthermore, when the error display is deleted unintentionally, the user can be appropriately notified that the error has occurred by redisplaying the error.

  (2) The operation system Pa that realizes the energy saving control function for switching between the sleep mode and the normal mode is installed in the mobile phone 10. Here, in the sleep mode state, the error display is not perceived by the user. For this reason, when an error occurs in the sleep mode, it is particularly desirable to display an error when the mode is shifted to the normal mode. Therefore, the utility value of the redisplay function is particularly great.

  (3) Once redisplay is performed, even if the redisplay content is deleted, the redisplay is not performed when shifting to the normal mode. As a result, it is possible to avoid a situation where an error is displayed unnecessarily in a situation where it is considered that an error has been notified to the user.

  (4) Even if the error display is deleted unintentionally, when the error is resolved, the display is not performed again. Thereby, the situation where incorrect information is notified to a user can be avoided.

  (5) When the error continuation time is equal to or greater than the threshold value Tth, it is possible to perform appropriate re-display according to the change of the situation by changing the error display content when the error occurs.

  (6) An error only when the elapsed time from when the user no longer performs an input operation to the user interface 20 until an error occurs is longer than a predetermined time and an inconvenience occurs due to an error (in the case of a fatal error) Was redisplayed. As a result, it is possible to reliably display defects that should be particularly notified to the user.

  (7) For each type of error, a table indicating the importance of displaying an error is stored in the print application Pb. Thereby, it is possible to appropriately determine whether or not the fatal error should be redisplayed.

<Other embodiments>
The present invention has been described above based on the embodiments. However, the present invention is not limited to the above embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. It can be easily guessed. Examples of modifications are listed below.

"About multiple programs"
The operation system as one of the plurality of programs is not limited to the one exemplified in the above embodiment. Further, the program that is considered to delete the error display is not limited to the operation system. Even in the case of an application program or the like, it is effective to apply the present invention if the error display is deleted.

About the detection function
In the above embodiment, as an example of the detection function, the storage area storing that the error display has been deleted in a situation where the error display is not deleted by the print application Pb itself is exemplified by accessing the storage area at a predetermined cycle through the API. Absent. For example, the storage area may be accessed using a transition from the sleep mode to the normal mode as a trigger. However, the processing itself for accessing the storage area is not essential. For example, it may be a function for detecting the transition from the sleep mode to the normal mode. Further, for example, a page display request that occurs in accordance with the transition from the sleep mode to the normal mode may be input. Incidentally, the determination of the presence / absence of a page display request is shown in step S42 of FIG.

"Redisplay restriction function"
In the above embodiment, as a re-display restriction function, once re-display is performed, error display is not performed even if the content that has been re-displayed after shifting from the sleep mode to the normal mode again is deleted (FIG. 5, step). S44: YES) is exemplified, but not limited to this. For example, the re-display may be performed two or more specified times, and thereafter, even if the error display (re-display) is turned off, the re-display may not be performed. For example, the re-display process of FIG. 5 is terminated on the condition that the number of times of affirmative determination in step S44 is a predetermined number of times, while the step of step S44 is performed on the condition that the number of positive determinations is less than the predetermined number of times This can be realized by shifting to S46. In this case, the probability that the user confirms the error display can be increased as the specified number is increased.

"Display function"
In the above embodiment, the display function is assumed to fix the error display content, but is not limited thereto. For example, when displaying the time until the error is resolved, the time may be updated in real time.

"Redisplay function"
Redisplay objects by the redisplay function are not limited to those exemplified in the above embodiment. For example, all errors to be displayed may be displayed again. Further, for example, not only the table using the degree of display importance for each type of error but also the redisplay target can be set by the user, and the redisplay target may be set as the redisplay target.

"Energy saving control function"
The sleep mode realized by the energy saving control function is not limited to the one that stops the display function. For example, although the image display means is an LCD and the backlight is turned off, the driving of the liquid crystal may be continued. Further, for example, the light emission amount may be reduced by a value larger than zero than in the normal mode.

"About hardware means"
The multi-function mobile terminal as hardware means is not limited to the mobile phone 10 and may be a tablet terminal having no telephone function, for example. However, the hardware means is not limited to a portable wireless communication device, and may be a desktop computer, for example.

"others"
The process of storing the type of error in the area for storing the error redisplay target in the memory 16 is not limited to the process performed at the timing shown in FIG. It may be performed at the time (when affirmative determination is made in step S12 of FIG. 4).

  As a technique for determining whether or not the error display has been deleted against the intention of the printing application Pb, the CPU 14 determines whether or not a negative determination is made in the process of step S32 as illustrated in FIG. It is not restricted to what is transferred to the process. For example, the processes in steps S32 and S34 may be independent of the process in step S36. In this case, when making a positive determination in step S36, the CPU 14 may determine whether or not it is immediately after the process of step S34.

  The display function, the detection function, and the re-display function are not limited to software processing, and hardware means for realizing these functions may be configured.

  14 ... CPU (one embodiment of hardware means and control unit), 30 ... MFP (one embodiment of recording apparatus), S14 ... one embodiment of display function, S44 ... one embodiment of prohibiting means, S46 ... duration One embodiment of the determination function, S50, S52...
