Description

  The present invention relates to a linked display system that links a screen of a portable terminal and a screen of an image processing apparatus, an image processing apparatus, a program thereof, and a linked display method.

  In recent years, MFPs (Multi Function Peripherals) such as image forming apparatuses having functions such as printers, scanners, and facsimiles have been designed to save power consumption of the MFP with less power consumption than usual from the viewpoint of energy saving. It often has a function to shift to the power mode. For example, MFPs that shift to a power saving mode when a specified time (for example, one minute) has elapsed in a standby state, such as a state in which an operation is not accepted or a job is not being executed, are generally widely used.

  However, when the MFP frequently shifts to the power saving mode, the user must return the MFP from the power saving mode every time the MFP is used. Therefore, a plurality of techniques for limiting the transition to the power saving mode have been proposed.

  For example, Patent Document 1 discloses a method for preventing an MFP from entering a sleep mode while a setting input is being performed by a PC (Personal Computer) printer driver (see Patent Document 1). ).

  Further, Patent Document 2 discloses that an MFP shifts to a power saving mode without impairing the user's convenience by confirming whether or not the client device that transmits the job is permitted to shift to the power saving mode. A method is disclosed.

  By the way, a user may use a portable terminal such as an MFP and a tablet at the same time. For example, the user arranges the display unit of the MFP and the portable terminal side by side, and uses the two display units to display one large screen, or an explanation (guidance) screen for operations on the screen displayed by the MFP. On your mobile device. In the above-described example, when one of the screens is switched, the display contents of both devices are linked so that the other screen is switched.

  When the user uses the MFP and the portable terminal at the same time and links the display contents of both apparatuses, if the operation on the MFP is not performed for a certain period of time, such as by slowly checking the contents displayed on the portable terminal, the MFP Will shift to power saving mode. In that case, the user needs to release the power saving mode and wait until the operation becomes possible. Further, when resetting the setting contents that have been performed when the MFP shifts to the power saving mode, the user has to redo the setting. Therefore, even in such a case, it is necessary to limit the transition to the power saving mode.

  The method disclosed in Patent Document 1 does not support the case where the display contents of the screen displayed by the PC and the screen displayed by the MFP are linked.

  Note that if the display mode of the MFP and the portable terminal is shifted to a display mode in which the display contents of both screens are linked (referred to as a linked display mode), regardless of whether both devices are in use, the power saving mode Although a method of prohibiting the transition to is assumed, power is wasted if both devices are not used during the interlocking display mode.

  Further, in the method described in Patent Document 2, before the MFP shifts to the power saving mode, it is asked whether or not to shift to the power saving mode. Therefore, when the user operates only on the mobile terminal side while the display contents of the MFP and the mobile terminal are linked, the mobile terminal is often asked whether the MFP is allowed to enter the power saving mode. The convenience of the user who operates a portable terminal will be impaired.

  The operation display unit 50 includes a display unit 51 and an operation unit 52. Among these, the operation unit 52 includes a switch unit 53 such as a start button and a touch panel unit 54. The display unit 51 is configured by a liquid crystal display or the like, and fulfills a function of displaying various operation screens, setting screens, and the like.

  The touch panel unit 54 is provided on the display unit 51. The touch panel unit 54 detects a coordinate position on the display unit 51 pressed by a touch pen or a finger, a flick operation, a drag operation, and the like.

  The tilt sensor 47 detects the direction in which the display surface of the display unit 51 of the mobile terminal 40 faces. The method for detecting the tilt may be arbitrary. For example, the detection is performed using a sensor such as a gyro sensor or an electronic compass provided in the tilt sensor 47. The portable terminal 40 recognizes whether the display surface of the display unit 51 is upward or downward by detecting the inclination of the own device by the inclination sensor 47.

  The line-of-sight detection unit 48 detects the user's line of sight. The line-of-sight detection method may be arbitrary. For example, a detection camera is provided at the center of the upper edge of the operation display unit 50, an image captured by the detection camera is analyzed, and the user's line of sight is detected from the face orientation, the position of the pupil in the eye, and the like. The portable terminal 40 recognizes whether or not the user is looking at the display unit 51 by detecting the user's line of sight with the line-of-sight detection unit 48.

  In the present embodiment, the CPU 41 determines whether or not the own device is in use. The determination method will be described later.

  In the present embodiment, during execution of the interlocking display control, the CPU 41 causes the operation display unit 50 to display various guidance screens based on information received from the image forming apparatus 10 by the network communication unit 46. Further, the CPU 41 transmits the operation content received by the operation display unit 50 to the image forming apparatus 10 using the network communication unit 46.

  Next, a flow until the image forming apparatus 10 and the portable terminal 40 shift to the interlock display mode will be described.

  Next, a procedure for establishing communication between the image forming apparatus 10 and the portable terminal 40 will be described. When communication between the image forming apparatus 10 and the portable terminal 40 is established, the display mode of the own apparatus is shifted to the interlocked display mode, and the interlocked display control is started.

(1. When entering linked display mode from the image forming apparatus 10 side)
When entering the linked display mode from the image forming apparatus 10 side, first, it is determined whether or not the image forming apparatus 10 enters the linked display mode. The determination method will be described later. When it is determined that the interlock display mode is entered, it is checked whether or not there is a device (mobile terminal 40) that can communicate with the surroundings, and if there is a mobile terminal 40 that can communicate, communication with the mobile terminal 40 is established. For example, when it is determined that the linked display mode is entered and it is checked whether there is a device that can communicate with the surroundings, a list of devices that can communicate is displayed, and the user communicates with the device selected from the list. May be established. And if communication is established, it will enter into an interlocking display mode and an interlocking display control will be started with this portable terminal 40.

  If there is no device (portable terminal 40) that can communicate with the surroundings, it is determined that the interlocked display mode cannot be entered, and the check ends.

  In determining whether to enter the interlocked display mode, it is determined that the interlocked display mode is entered when an instruction to enter the interlocked display mode is received from the user or when a specific condition is satisfied.

  For example, when setting multiple items, it is necessary to set a certain item after or before other items (first priority, second priority, etc.) In this way, the setting is considered to be confusing for the user, or the user determines that he / she is in trouble because he / she does not know the setting operation method, such as going back and forth on the same screen. In addition, when the operation is not performed for a certain period of time on a specific screen, the user determines that the user does not know the setting operation method and is in trouble.

(2. When entering the interlocked display mode from the mobile terminal 40 side)
When communication is established from the mobile terminal 40 side, first, a linked display application is started on the mobile terminal 40, the application issues a communication establishment request to the image forming apparatus 10, and the image forming apparatus 10 that has received the communication establishment request. Communication is established. When communication is established, the display mode is switched to the linked display mode, and linked display control is started together with the image forming apparatus 10.

  In the interlocking display system 5, the portable terminal 40 and the image forming apparatus 10 determine whether or not the distance from the other device is equal to or greater than a predetermined value by exchanging position information before entering the interlocking display mode. To do. Then, only when it is determined that the distance is less than the predetermined value, the interlock display mode is entered, and execution of the interlock display control is started. When it is determined that the distance is greater than or equal to the predetermined value, the interlock display mode is not entered.

  For example, the predetermined value is a distance that allows the user to use the portable terminal 40 and the image forming apparatus 10 at the same time. Any method may be used for determining whether the distance between the portable terminal 40 and the image forming apparatus 10 is equal to or greater than a predetermined value.

  Next, a setting screen displayed by the image forming apparatus 10 that is executing the interlock display control in the interlock display mode will be described.

  FIG. 4 shows a copy setting screen 60 that is an example of a setting screen displayed by the image forming apparatus 10 that is executing the interlock display control in the interlock display mode.

  On the copy setting screen 60, a plurality of item buttons (61 to 67) for performing various settings relating to copying are displayed. Specifically, an item button 61 relating to the binding setting for stapling the output paper, an item button 62 relating to the single-sided / double-sided printing setting, an item button 63 relating to the (enlargement / reduction ratio) scale setting, and the paper to be used An item button 64 relating to selection (paper setting), an item button 65 relating to density setting, an item button 66 relating to monochrome / color setting, and an item button 67 relating to image quality setting are displayed.

  When any one of the item buttons 61 to 67 is selected, a screen of a lower hierarchy related to the selected item button is popped up and displayed on the copy setting screen 60 in an overlapping manner.

  FIG. 5 shows a binding setting screen 70 popped up when the item button 61 is selected. The binding setting screen 70 includes various setting items relating to stapling, punching, paper folding, and the like, an OK button 71 for confirming the setting relating to the setting item, and a cancel button 72 for canceling the setting. Has been placed. When the OK button 71 is pressed while a setting item in the binding setting screen 70 is selected, the image forming apparatus 10 confirms the setting contents in the selected state. When the cancel button 72 is pressed, the setting content selected in the binding setting screen 70 is canceled and the binding setting screen 70 is bound.

  As described above, the user displays the screen of the lower hierarchy related to each of the item buttons 61 to 67 and performs detailed settings on the screen.

  However, since the image forming apparatus 10 has a variety of functions, the user may not know what setting operation to perform in order to obtain the desired print result. In such a case, the user confirms each function and effect of the image forming apparatus 10 on the guidance screen displayed by the portable terminal 40 that is executing the interlocked display control together with the image forming apparatus 10, while checking the functions of the image forming apparatus 10. A setting operation is performed on the forming apparatus 10. Next, a guidance screen displayed by the portable terminal 40 that is executing the interlock display control in the interlock display mode will be described.

  FIG. 6 shows a copy guidance screen 80 which is an example of a guidance screen displayed on the mobile terminal 40 during execution of the interlocked display control. The copy guidance screen 80 is a screen corresponding to the copy setting screen 60 shown in FIG. 4. The copy guidance screen 80 is an operation procedure for copying, what settings should be performed to obtain a print result desired by the user, and copy settings. Items corresponding to the item buttons 61 to 67 on the screen 60 are displayed. The user can confirm the setting operation method and the like on the copy setting screen 60 on the copy guidance screen 80.

  When any item in the copy guidance screen 80 is selected, a transition is made to a screen showing a detailed description of the item. FIG. 7 shows a state in which the user selects an item relating to binding setting on the copy guidance screen 80.

  FIG. 8 shows a binding guidance screen 90 which is an example of a screen after transition when an item relating to binding setting is selected on the copy guidance screen 80. The binding guidance screen 90 displays detailed contents of each item relating to binding, such as stapling and punching. The user confirms the detailed content of each function related to binding on the binding guidance screen 90 and performs a setting operation on the image forming apparatus 10.

  The binding guidance screen 90 is a screen corresponding to the binding setting screen 70. When the image forming apparatus 10 receives the user's operation and displays the binding setting screen 70, the portable terminal 40 automatically displays the binding guidance screen 90. When the portable terminal 40 receives an operation and displays the binding guidance screen 90, the image forming apparatus 10 automatically displays the binding setting screen 70.

  Thus, in the interlocking display system 5, the image forming apparatus 10 and the mobile terminal 40 display a screen corresponding to the screen displayed by the other apparatus by interlocking display control. When one screen is switched, the other screen is also switched.

  In the interlocking display system 5, while the interlocking display control is being performed in the interlocking display mode, if either one of the image forming apparatus 10 and the portable terminal 40 is in use, both do not shift to the power saving mode. Next, a method for determining whether or not the image forming apparatus 10 and the portable terminal 40 are in use will be described.

  The image forming apparatus 10 determines whether or not the image forming apparatus 10 is in use based on at least one of the user's line of sight detected by the line-of-sight detection unit 21 or the operation status received by the apparatus from the user. Specifically, when the user's line of sight detected by the line-of-sight detection unit 21 is directed on the operation panel 30 or until a predetermined time has elapsed since the last operation was received, the own apparatus is in use. It is judged that.

  Whether or not the mobile terminal 40 is in use based on at least one of the user's line of sight detected by the line-of-sight detection unit 48, the detection result of the tilt sensor 47, and the status of the operation received by the self-device from the user. Judging. Specifically, when the user's line of sight detected by the line-of-sight detection unit 48 is pointed on the operation display unit, or until a certain time has elapsed since the last operation was received, the own apparatus is in use. Recognize that there is. Further, while the display unit 51 recognizes that the display surface of the display unit 51 is facing downward based on the detection result of the tilt sensor 47, it is determined that the own device is not being used.

  In the interlocking display system 5, during execution of interlocking display control in the interlocking display mode, the image forming apparatus 10 and the mobile terminal 40 repeatedly report to the other whether or not their own apparatus is in use. When either one of the image forming apparatus 10 and the portable terminal 40 is in use, the image forming apparatus 10 and the portable terminal 40 do not shift to the power saving mode. When both the devices are not used, the mode is shifted to the power saving mode. When the mode is shifted to the power saving mode, the communication between the image forming apparatus 10 and the portable terminal 40 is disconnected.

  In the interlocking display system 5, if the interlocking display control is not being executed, the power mode of the image forming apparatus 10 is independently controlled based on whether the image forming apparatus 10 is in use. Further, the power mode of the mobile terminal 40 is independently controlled based on whether or not the mobile terminal 40 is in use. That is, when the interlocking display control is not executed, a device that is in use does not shift to the power saving mode, and a device that is not used shifts to the power saving mode.

  Next, processing performed after the image forming apparatus 10 and the portable terminal 40 start interlocking display control in the interlocking display mode and before shifting to the power saving mode will be described.

  FIG. 9 shows processing performed by the image forming apparatus 10 after starting linked display control in the linked display mode until shifting to the power saving mode. First, communication with the portable terminal 40 is established, the mode is shifted to the linked display mode, and linked display control is started (step S101).

  Whether or not the device itself is in use is checked by the above-described method. If the device is in use (step S102; Yes), the process returns to step S102 to continue the processing. If the own device is not used (step S102; No), it is determined whether the portable terminal 40 is in use based on information received from the portable terminal 40 (step S103).

  If the portable terminal 40 is used (step S103; Yes), it will return to step S102 and will continue a process. If it is not in use (step S103; No), it shifts to the power saving mode while keeping the interlocking display mode (step S104), and this process is terminated.

  FIG. 10 shows processing that is performed from when the mobile terminal 40 starts linked display control in the linked display mode to when the portable terminal 40 shifts to the power saving mode. First, communication with the image forming apparatus 10 is established, the mode is shifted to the linked display mode, and linked display control is started (step S201).

  Whether or not the device itself is in use is checked by the above-described method. If the device is in use (step S202; Yes), the process returns to step S202 and continues. If the image forming apparatus 10 is not in use (step S202; No), it is determined whether the image forming apparatus 10 is in use based on information received from the image forming apparatus 10 (step S203).

  If the image forming apparatus 10 is being used (step S203; Yes), the process returns to step S202 and continues. If it is not in use (step S203; No), it shifts to the power saving mode while keeping the interlocking display mode (step S204), and this process is terminated.

  Next, a case where the interlocking display mode is terminated will be described. When the linked display system 5 is in the linked display mode and receives a setting operation from the user, the linked display mode 5 ends when the setting operation is completed.

  For example, when the setting completion button is pressed or when an operation for starting a job related to the setting operation received during the interlocking display mode is received, it is determined that the setting operation is completed, and the interlocking display mode is ended. .

  FIG. 11 shows processing performed after the image forming apparatus 10 starts executing the interlocked display control in the interlocked display mode until the interlocked display mode is canceled. First, communication with the portable terminal 40 is established, and interlocked display control is started in the interlocked display mode (step S301).

  When an operation for starting a job related to the setting operation is received, it is determined that the setting operation from the user has been completed (step S302; Yes), the interlocked display mode is canceled, and communication with the mobile terminal is disconnected ( Step S303), the process is terminated. Until it is determined that the setting operation has been completed (step S302; No), the process returns to step S302 and continues.

Note that the image forming apparatus 10 also determines that the setting operation has been completed and cancels the interlocked display mode even when at least one of the following two conditions is satisfied during the interlocked display mode.
When the setting completion button is pressed on the operation panel 30 When the setting completion button is pressed on the mobile terminal 40

  Next, a case where the image forming apparatus 10 and the portable terminal 40 shift to the power saving mode and return from the power saving mode while the linked display control is being executed in the linked display mode will be described.

  In the interlocking display system 5, when both the image forming apparatus 10 and the portable terminal 40 are not in use in the interlocking display mode, the image forming apparatus 10 and the portable terminal 40 recognize that fact, and perform the respective controls. Both of them shift to the power saving mode while keeping the interlocking display mode. And when it transfers to a power saving mode with an interlocking display mode, when either one returns from a power saving mode, the other is also returned from a power saving mode. That is, during the interlocking display mode, the image forming apparatus 10 and the portable terminal 40 are shifted to the power saving mode together or returned from the power saving mode together.

  For example, when the portable terminal 40 is returned from the power saving mode after both the image forming apparatus 10 and the portable terminal 40 are shifted to the power saving mode in the interlocking display mode, the portable terminal 40 is connected to the image forming apparatus 10. A request to return from the power saving mode is transmitted, and after receiving the request, the image forming apparatus 10 resumes the linked display control together with the portable terminal 40 that has transmitted the request.

  Next, referring to FIG. 12, a case will be described in which the image forming apparatus 10 is returned to the power saving mode after being shifted to the power saving mode while being in the interlocked display mode.

  FIG. 12 shows processing performed when the image forming apparatus 10 returns to the power saving mode after shifting to the power saving mode while maintaining the interlocking display mode. First, after the image forming apparatus 10 shifts to the power saving mode in the interlocked display mode and then returns from the power saving mode in response to an operation or the like (step S401), the image forming apparatus 10 is moved to the vicinity to shift to the power saving mode. At the same time, it is checked whether or not there is a portable terminal 40 that has performed the interlocking display control (step S402).

  Specifically, a communicable device in the vicinity is examined, and it is determined whether or not there is a mobile terminal 40 that has performed the interlock display control. When the portable terminal 40 is in the vicinity (step S402; Yes), a request for returning from the power saving mode is transmitted to the portable terminal 40 (step S403), and the portable terminal 40 returns from the power saving mode. Then, the interlocking display control is resumed and this process is terminated.

  When the portable terminal 40 that has performed the interlocking display control is not in the vicinity (step S402; No), the interlocking display mode is canceled (step S404), and this process ends. Note that when the image forming apparatus 10 returns from the power saving mode that has been switched to the linked display mode, even if there is a terminal other than the portable terminal 40 that has performed linked display control until the shift to the power saving mode is performed nearby. The linked display mode is canceled without performing linked display control with the terminal.

  Thus, in the interlocking display system 5, the display contents of the image forming apparatus 10 and the portable terminal 40 are interlocked by interlocking display control. While the interlocked display control is being executed in the interlocked display mode, if either the image forming apparatus 10 or the portable terminal 40 is in use, control is performed so that both the apparatuses are not shifted to the power saving mode. Thus, for example, even when the operation of the image forming apparatus 10 is not performed for a certain period of time by slowly confirming the content of the guidance screen displayed on the mobile terminal 40 during the interlocked display mode, the image forming apparatus It is possible to prevent the occurrence of a situation in which 10 shifts to the power saving mode and the setting contents that have been performed are canceled.

  In addition, when both devices are not in use, even in the linked display mode, the mode is shifted to the power saving mode. Can be suppressed.

  The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to that shown in the embodiment, and there are changes and additions within the scope of the present invention. Are also included in the present invention.

  In the embodiment of the present invention, the user's setting operation is received only by the image forming apparatus 10, but the mobile terminal 40 may receive the setting operation. Specifically, the portable terminal 40 displays a guidance screen on which settings similar to the setting screen displayed on the image forming apparatus 10 can be performed, and the contents of the setting operation received on the guidance screen are displayed on the image forming apparatus 10. Send. Then, the image forming apparatus 10 reflects the contents of the setting operation received by the mobile terminal 40 on the own apparatus.

  In the embodiment of the present invention, the portable terminal 40 can shift to the power saving mode, but the portable terminal 40 may not be able to shift to the power saving mode. In this case, in the interlocking display mode, if either one of the image forming apparatus 10 and the portable terminal 40 is in use, the transition to the power saving mode may be prohibited in the power mode of the image forming apparatus 10. .

  In the embodiment of the present invention, the image forming apparatus 10 in the interlocking display system 5 has been described as an example of the image processing apparatus, but the image processing apparatus is not limited to this. The image processing apparatus may be configured by extracting the CPU 11, the ROM 12, the RAM 13, the nonvolatile memory 14, the network communication unit 20, and the image processing unit 16 from the image forming apparatus 10. The present invention also relates to a program for operating the above-described image processing apparatus, information processing apparatus as in the embodiment, and a linked display method for causing the image processing apparatus and the mobile terminal to perform linked display control in the embodiment. May be.

  A case where the image processing apparatus is operated alone instead of the interlocking display system 5 will be described. The image processing apparatus transmits information (display data and the like) for displaying the guidance screen to the portable terminal while performing the interlock display control in the interlock display mode.

  During the linked display mode, information related to the usage status of the mobile terminal is received, and if either the image processing device or the mobile terminal is in use, the mobile terminal is prohibited from entering the power saving mode. Send instructions to do. When shifting to the power saving mode or returning from the power saving mode with the interlocking display mode, an instruction to shift to the power saving mode and an instruction to return from the power saving mode are transmitted to the portable terminal. When the display mode is not the interlocking display mode, the mobile terminal is caused to control the power mode of the mobile terminal independently.

  In the embodiment of the present invention, each of the image forming apparatus 10 and the portable terminal 40 determines whether or not to prohibit the transition to the power saving mode for the power mode of the own apparatus in the interlocking display mode. However, for example, a server is provided as the power saving control unit of the present invention, and the server determines whether or not the image forming apparatus 10 and the portable terminal 40 in the interlocking display mode are prohibited from entering the power saving mode. May be. Specifically, the server acquires information related to the usage status of the image forming apparatus 10 and the portable terminal 40 in the linked display mode, and based on the information, the image forming apparatus 10 and the portable terminal 40 are in the power saving mode. An instruction to prohibit the transition to is sent.

  In the embodiment of the present invention, each of the image forming apparatus 10 and the portable terminal 40 controls the power mode of the own apparatus. However, an external device such as a server is provided, and the server is connected to the image forming apparatus 10. The power mode of the mobile terminal 40 may be controlled. Specifically, the server acquires information related to the usage status of the image forming apparatus 10 and the portable terminal 40, and based on the information, instructs the image forming apparatus 10 and the portable terminal 40 to enter the power saving mode. Then, an instruction to return from the power saving mode is transmitted.
