  Next, FIG. 11 is referred to for the processing procedure of information display. FIG. 11 is a flowchart illustrating an example of a processing procedure of image data display.

  This processing procedure is an example of an information display program and method of the present disclosure. This processing procedure includes a process in which the captured image acquired by the information processing apparatus 12 (FIGS. 4 and 9) is provided as the projection image 26 at the time of holding.

  Therefore, in this processing procedure, as shown in FIG. 11, before the image data is changed, the image data in the image data source 54 is transferred from the display switching unit 56 to the display unit in accordance with an instruction from the input processing unit 66 (FIG. 8). 18 and the projection screen 24 of the projection device 14 (step S31). In this case, the image data provided to the display unit 18 and the projection device 14 is common, and the same image is displayed on the display unit 18 and the projection screen 24.

  While the image data is being displayed, the input processing unit 66 monitors the hold operation (step S32) and determines whether there is a hold operation. If there is no hold operation (NO in step S32), the common display image of the projection device 14 and the display unit 18 is maintained.

  If there is a hold operation (YES in step S32), at the time of operation, the input processing unit 66 instructs the data processing unit 62 to acquire (capture) the image data at that time from the image data source 54 (step). S33).

  The data processing unit 62 acquires the image data, stores the image data in the information storage unit 64 together with the history information, and saves it (step S34).

  Then, a hold signal is sent from the input processing unit 66 to the display switching unit 56, and an instruction is sent from the display switching unit 56 to the transmission unit 58 to transmit the image data (capture image) stored in the information storage unit 64 (step S35). ).

When an image data editing operation or the like is performed, the edited image is displayed in real time on the display unit 18 and the editing operation can be confirmed. Since the projected image 26 being displayed is fixed in the hold state in the projection device 14, the progress of editing work by the input processing unit 66 and its transition data are not displayed.

  While the image data is being changed, that is, while the captured image is being displayed on the projection screen 24, the input processing unit 66 monitors the hold release operation (step S37) and determines whether there is a hold release operation. If the hold release operation is not performed (NO in step S37), the projection device 14 maintains the display of the captured image, and the display unit 18 displays the image data being changed.

  If there is a hold release operation in the input processing unit 66 (YES in step S37), the input processing unit 66 sends a hold release signal to the display switching unit 56, and the display switching unit 56 sends an image data source to the transmission unit 58. 54 is instructed to transmit the edited image data (step S38).

  Upon receiving such an instruction, the transmission unit 58 switches from the captured image currently being transmitted to the image data of the image data source 54 and transmits it to the projection control unit 68. As a result, the image data of the image data source 54 is displayed on the projection screen 24 (step S39), and the display of the projection screen 24 is shared with the display unit 18.

  Then, the display end of the display process is monitored (step S40), and if the display end is not selected (NO in step S40), the process returns to step S31 and the above process is continued. If the display is finished (YES in step S40), this process is finished.

  Next, FIG. 12 is referred with respect to the change of the image data. FIG. 12 is a diagram illustrating an example of the image data history table.

  The image data history table 92 stores an image data ID 94, a change date 96, a change location 98, and a change content 100. In the image data ID 94, ID (IDentification) is stored as identification information for identifying the image data. For example, in addition to the title, the author, the date of writing, a summary sentence, a pickup image, and the like are stored. In the change date and time 96, the date and time when the image data was changed is recorded. The change part 98 stores information for specifying the change part of the image data. For example, in the case of document data, the page, the number of lines, the range of the change part, and the like are stored. The change content 100 stores information indicating the change content of the image data, for example, edit content.

  With respect to the second embodiment described above, features, advantages, modifications, and the like are listed.

  (1) The information processing apparatus 12 has a function of holding the projection image 26 with respect to the projection screen 24. When the hold operation is performed, image data is captured at that time, and if the hold state continues, the same projection image 26 is displayed on the projection screen 24 of the projection device 14. At this time, the image data of the image data source 54 is displayed on the display unit 18 serving as a primary monitor (primary display) and is in an editable state. When a hold release operation is performed in the information processing apparatus 12 after a change operation such as editing is completed, the edited image data is displayed on the projection screen 24 of the projection apparatus 14. In order to realize such a hold and hold release, the information processing apparatus 12 has a transmission function for transmitting image data to be displayed on the projection apparatus 14 that is a secondary monitor (secondary display) of the image data captured in response to the hold operation. Have. In this case, since the image data to be transmitted to the projection device 14 is selected on the information processing device 12 side, it is not necessary to provide a hold function or an image selection function on the projection device 14 side.

  (2) The hold operation and the hold release operation may be performed by assigning a hold (or hold release) function to the keyboard key in the keyboard operation.

  (3) Besides the keyboard operation, a soft key is displayed on the display unit 18 of the information processing device 12 as a task when the projection device 14 is connected, and is operated by a mouse operation or a touch operation, and the projection image 26 is held. Alternatively, the hold may be released.

  (4) In response to the data acquisition instruction from the input processing unit 66, the data processing unit 62 stores the image data acquired from the image data source 54 in the information storage unit 64 together with history information. The information storage unit 64 includes an image data storage unit 82 and a history storage unit 84.

  (5) The display switching unit 56 receives the hold release notification from the input processing unit 66 and switches the image data of the image data source 54 to be transmitted to the projection device 14 via the transmission unit 58. In this case, the image data acquired by the hold operation is a captured image that is a still image, and has a smaller data capacity than the image data developed on the display unit 18, and a series of processing from capture to display is performed. Easy. In addition, an operation such as scrolling or correction may be enabled on the projection screen 24 on which the still image is developed.

  (6) The information processing device 12 is constituted by an information processing terminal such as a personal computer or a mobile phone, and an electronic device having a data transmission function, and the projection device 14 projects received data such as an image monitor or a television receiver. What is necessary is just to comprise with the electronic device which has a function. In the above embodiment, the information display device of the present disclosure is exemplified by the information processing device 12 as a portable computer and the projection device 14 as a projector, but is not limited thereto.

  (7) The information processing device 12 and the projection device 14 may be connected by any mechanism capable of transmitting data, whether wired or wireless. For wired connection, a USB (Universal Serial Bus) cable or LAN (Local Area Network) may be used, and for wireless connection, a short-distance wireless connection such as Bluetooth may be used.

  (8) When the operator waiting on the information processing apparatus 12 side performs a hold operation, the projection image 26 displayed on the projection screen 24 of the projection apparatus 14 can be placed in the hold state.

  (9) Display information changes such as display correction and editing can be performed using only the display on the display unit 18 until the change contents are finalized (that is, until the hold is released). Is expensive.

  (10) The operator can process the display information without stress and is freed from the monitoring status of the participants and viewers. Further, when the same image is projected for a certain period of time, once the projection image 26 is held, another operation can be performed on the information processing apparatus 12 side, and the time can be effectively used. Also, when projecting with a two-screen operation, the images displayed on the primary monitor and the secondary monitor are different, so it is difficult to edit and operate on the spot. It is easy to operate, and it is possible to construct a highly convenient information display system such that display information can be freely changed.

[Third Embodiment]

  In the third embodiment, image data is held on the information processing apparatus and the projection apparatus side.

  The third embodiment will be described with reference to FIG. FIG. 13 is a flowchart illustrating an example of an information display processing procedure.

  Also in the information display device 2C (FIG. 14) of this embodiment, the above-described information display device 2B (FIGS. 4, 5, and 6) is used, and the hardware configuration (FIG. 9) of the information processing device 12 is also used. It is the same.

  The processing procedure of the information display apparatus 2C of this embodiment is an example of the information display program and method of the present disclosure, and is a process performed when the projection apparatus 14 is provided with a hold function for image data.

  Therefore, in this processing procedure, as shown in FIG. 13, material projection is performed by the projection device 14 (step S41). This material projection is an example of information display. After the document projection, the projection image hold operation is monitored (step S42). If the hold operation is not performed (NO in step S42), the process returns to step S41.

  When the hold operation is performed (YES in step S42), the information processing device 12 and the projection device 14 hold the projection image (step S43). That is, in this case, the projection image hold is to hold the display of the projection image 26 being projected on the projection device 14 side.

  During the hold operation, the hold release operation is monitored (step S44). When the hold release operation is not performed (NO in step S44), the process returns to step S43. When the hold release operation is performed (YES in step S44), the projection image hold release is executed (step S45), the projection image 26 is changed (step S46), and the edited display information (display image) is stored in the information storage unit. 64 (image data storage unit 82) (step S47), and the process returns to step S41.

  According to such processing, both the information processing device 12 and the projection device 14 have a hold function for image data. When the image data hold operation is performed, the information processing apparatus 12 captures the image data displayed at the time of the hold. The captured image data is transmitted to the projection device 14. The projection device 14 projects the capture image transmitted from the information processing device 12 onto the projection screen 24 (FIG. 4).

  In this case, the information processing apparatus 12 continuously displays editable image data from the image data source 54 on the display unit 18 and transmits the image data to the projection apparatus 14, but the projection apparatus 14 switches the image data to be displayed. . For this reason, the image data (capture image) at the time of holding is displayed on the projection screen 24. When the image data changing operation is completed in the information processing device 12 and the hold releasing operation is performed, the projection device 14 is switched to display of the image data displayed on the display unit 18. In this case, the held captured image is stored in the information storage unit 64 together with the history information.

  In such an image display, the function of transmitting the captured image data to the projection device 14 triggered by the hold operation on the information processing device 12 side, and the image data received at the same time receiving the image data in response to the hold operation on the projection device 14 side. A function for holding and displaying and a display switching function for image data when the hold is released may be provided. The capture image holding function may use a recording medium such as a USB memory, a Bluetooth memory, or a flash memory.

  Next, FIG. 14 will be referred to regarding the information display function unit. FIG. 14 is a diagram illustrating an example of a functional unit of the information display device according to the third embodiment. 14, the same parts as those in FIG. 8 are denoted by the same reference numerals.

  As shown in FIG. 14, the functional unit of the information display device 2C includes an image data source 54, a transmission unit 58, a display control unit 60, a data processing unit 62, and an information storage unit 64 on the information processing device 12 side. And an input processing unit 66. The projection device 14 includes a projection control unit 68, a data processing unit 102, and an information storage unit 104. That is, the functional unit of the information display device 2C is configured by adding the data processing unit 102 and the information storage unit 104 to the projection device 14 side of the second embodiment (FIG. 8), and other functional units. Is the same as in the second embodiment.

  The data processing unit 102 receives various instructions from the input processing unit 66 and executes various functions. This function includes a function for capturing image data being displayed, an instruction for saving a captured image to the information storage unit 104, an image switching function, a transfer of image data from the information storage unit 104 to the information storage unit 64, and an image for the information storage unit 64. Functions such as saving instructions are included. In this case, the data processing unit 102 may perform these processes via the data processing unit 62 on the information processing apparatus 12 side. That is, the image switching function by the display switching unit 56 in the second embodiment is executed by, for example, the input processing unit 66, the data processing unit 62, the image data source 54, and the transmission unit 58.

  The information storage unit 104 is a functional unit that stores image information, and stores image data being projected based on an instruction from the data processing unit 102.

  Unlike the second embodiment, the data processing unit 62 of this embodiment may be configured to exchange control information and exchange image data with the data processing unit 102.

  Therefore, in this information display device 2C, the input processing unit 66 receives a hold instruction, and captures the image data displayed on the display unit 18 at that time to the data processing unit 62 and obtains it as the image data file. Instruct. At the same time, a hold notification is sent to the projection control unit 68 of the projection device 14.

  The data processing unit 62 receives an image data file acquisition instruction from the input processing unit 66, and transfers the acquired image data file to the information storage unit 104. At this time, the transfer method includes infrared rays, a dedicated connection code, Bluetooth, and the like.

  After receiving the hold notification from the input processing unit 66, the projection control unit 68 of the projection device 14 confirms whether the image data file is stored in the information storage unit 104, opens the file, and is transmitted from the transmission unit 58. The projection is switched from the projection of the existing image data to the projection of the image data file in the information storage unit 104.

  At this time, since the projection control unit 68 of the projection device 14 switches the image data to be projected, the information processing device 12 does not need to stop image data transmission from the transmission unit 58.

  Also, if there is an input for releasing the hold from the input unit 16, the input processing unit 66 notifies the projection control unit 68 of the projection device 14 of the release of hold.

  Upon receiving a hold release notification from the input processing unit 66, the projection control unit 68 switches to the projection of the image data transmitted from the information processing device 12.

  The input processing unit 66 notifies the data processing unit 102 of the release of the hold, and the data processing unit 102 that has received the notification sends the image data file held and projected in the information storage unit 104 to the information storage unit 64 together with history information. Forward. At this time, the transferred image data on the information storage unit 104 side is discarded, and the information storage unit 104 is efficiently used. If the hold operation is performed multiple times, the data is not overwritten, but automatically renamed as a separate file and saved entirely.

  According to such a configuration, a captured image that is a still image is acquired by the hold operation, and as a merit, as described above, the data capacity is small and a series of processing is facilitated.

  In the information display device 2C, the capture image holding function is shifted to the projection device 14 side, and when the hold is released, the image data stored in the information storage unit 104 is transferred to the information storage unit 64 and stored. The burden on the information processing apparatus 12 is reduced by sharing the image data storage function.

  And in order to implement | achieve such a function part, since the hardware of the information processing apparatus 12 is the same as that of 2nd Embodiment (FIG. 9), the description is abbreviate | omitted.

  In this information display device 2C, the display unit 18 corresponds to the primary monitor, the projection screen 24 corresponds to the secondary monitor, and the two images are not operated, and the same image is displayed on the primary monitor and the secondary monitor. For example, the projection device 14 may be a projector, but may be an external display device.

  Also in this embodiment, the input unit 16 is input means such as a keyboard or a pointing device, and the input unit 16 may be provided with a key for hold instruction.

  Next, FIG. 15 will be referred to for hardware that realizes the functional units of the projection device 14. FIG. 15 is a diagram illustrating a hardware configuration example of the projection apparatus. 15, the same parts as those in FIG. 10 are denoted by the same reference numerals.

  In order to implement the projection control unit 68, the data processing unit 102, and the information storage unit 104, the projection device 14 includes a memory unit 106 as shown in FIG. Part 108 is provided.

  In the memory unit 106, the processor 86 controls data writing or reading. An image data storage unit 108 is set in the memory unit 106, and captured image and image change history information is stored in the image data storage unit 108. As described above, the image data and the history information in the memory unit 106 are transferred to the information storage unit 64 side when the hold is released.

  Since the other configuration of the projection device 14 is the same as that of the second embodiment, the description thereof is omitted.

  Next, FIG. 16 is referred to for the information display processing procedure on the information processing apparatus 12 side. FIG. 16 is a flowchart illustrating an example of a processing procedure of image data display.

  This processing procedure is an example of an information display program and method of the present disclosure. This processing procedure includes a process in which a captured image acquired by the data processing unit 62 in accordance with an instruction from the information processing apparatus 12 (FIGS. 4 and 9) is provided as the projection image 26 at the time of holding.

  Therefore, in this processing procedure, as shown in FIG. 16, normal processing is executed before the hold operation (step S51). As described above in the second embodiment, this normal processing means that the image data in the image data source 54 is displayed on the display unit 18 according to an instruction from the input processing unit 66 (FIG. 14) before the image data is changed. And displayed on the projection screen 24. In this case, the image data provided to the display unit 18 and the projection device 14 is common, and the same image is displayed on the display unit 18 and the projection screen 24.

  During the display of the image data by this normal processing, the input processing unit 66 monitors the hold operation (step S52) and determines whether there is a hold operation. If there is no hold operation (NO in step S52), the common display image on the projection screen 24 and the display unit 18 is maintained. That is, the normal process (step S51) is maintained.

  If there is a hold operation (YES in step S52), the input processing unit 66 instructs the data processing unit 62 to acquire (capture) the image data displayed at that time from the image data source 54. (Step S53).

  The data processing unit 62 acquires the image data and transfers the image data to the information storage unit 104 (step S54).

  Then, the input processing unit 66 sends a hold signal to the projection control unit 68 (step S55).

  The display control unit 60 displays the image data of the image data source 54 on the display unit 18, and the transmission unit 58 transmits the image data of the image data source 54 to the projection control unit 68 (step S56). The user can edit or change the image data from the input processing unit 66. Although this change is displayed on the display unit 18, since the captured image is displayed on the projection screen 24 during the change of the image data, the image data being changed and the operation thereof are not displayed.

  While the image data is being changed, that is, while the captured image is being displayed on the projection screen 24, the input processing unit 66 monitors the hold release operation (step S57) and determines whether there is a hold release operation. If the hold release operation is not performed (NO in step S57), the projection device 14 maintains the display of the captured image, and the display unit 18 displays the image data being changed.

  If there is a hold release operation in the input processing unit 66 (YES in step S57), a hold release signal is sent from the input processing unit 66 to the projection control unit 68 (step S58). A hold release signal is sent from the input processing unit 66 to the data processing unit 102 (step S59).

  The information storage unit 64 stores the data file transmitted from the data processing unit 102 as an editing history (step S60). As a result, the image display on the display unit 18 based on the image data on the display control unit 60 side and the projection image 26 displayed on the projection screen 24 on the projection control unit 68 side are the same.

  Then, the display end of the display process is monitored (step S61). If the display end is not selected (NO in step S61), the process returns to step S51 and the above process is continuously executed. If the display is finished (YES in step S61), this process is finished.

  Next, FIG. 17 will be referred to regarding the processing procedure on the projection device 14 side. FIG. 17 is a flowchart illustrating an example of a processing procedure of image data display.

  Before the hold operation, in the projection device 14, the projection control unit 68 projects the image data of the image data source 54 on the projection screen 24 and displays it (step S71). Whether the image data is sent from the data processing unit 62 is monitored (step S72). If the image data is sent (YES in step S72), the information storage unit 104 holds the image data (step S73).

  It is monitored whether there is a hold instruction notification from the input processing unit 66 to the projection control unit 68 (step S 74). If there is a hold instruction notification (YES in step S 74), the projection control unit 68 receives from the input processing unit 66. In response to the hold signal, the information storage unit 104 is referred to (step S75).

  The projection control unit 68 confirms whether there is image data in the information storage unit 104 (step S76). If there is image data (YES in step S76), the projection control unit 68 displays the image data in the information storage unit 104 on the projection screen 24 with priority over the image data from the transmission unit 58 (step S77).

  It is monitored whether there is a hold release notification from the input processing unit 66 to the projection control unit 68 (step S78). If there is a hold release notification (YES in step S78), the projection control unit 68 receives the hold release signal from the input processing unit 66 and displays the image data of the image data source 54 from the transmission unit 58 on the projection screen 24. (Step S79). That is, the display is switched to display of image data from the image data source 54.

  It is monitored whether there is a hold release notification from the input processing unit 66 to the data processing unit 102 (step S80). If there is a hold release notification (YES in step S80), the data processing unit 102 receives the hold release signal from the input processing unit 66, and stores the image data file in the information storage unit 104 in the information storage unit 64 (step S80). S81).

  Next, an image display processing sequence will be described with reference to FIG. FIG. 18 is a flowchart illustrating an example of a processing sequence of image data display.

  In this processing sequence, the relevance of the processing of the information processing device 12 and the projection device 14 is mentioned with respect to the processing procedures (FIGS. 16 and 17) of the information processing device 12 and the projection device 14 described above.

  Therefore, the information processing device 12 and the projection device 14 execute the above-described normal processing (step S91). During the display of the image data by the normal processing, the information processing apparatus 12 monitors the hold operation by the input processing unit 66 (step S92) and determines whether there is a hold operation. If there is no hold operation (NO in step S92), the normal process (step S91) is maintained.

  If there is a hold operation (YES in step S92), at the time of the operation, the input processing unit 66 acquires (captures) the displayed image data from the image data source 54 to the data processing unit 62. An instruction is given (step S93).

  The data processing unit 62 acquires image data (captured image), and transfers the image data to the information storage unit 104 (step S94). In response to this, in the projection device 14, the information storage unit 104 holds image data (step S95).

  Then, the input processing unit 66 of the information processing apparatus 12 sends a hold signal to the projection control unit 68 and the data processing unit 102 (step S96). On the projection device 14 side, the data processing unit 102 receives the hold signal from the input processing unit 66 and refers to the information storage unit 104 (step S97).

  The data processing unit 102 confirms that there is image data in the information storage unit 104, and opens the corresponding image data file (step S98). The projection control unit 68 displays the image data from the data processing unit 102 on the projection screen 24 with priority over the image data from the transmission unit 58 (step S99).

  While the image data is being changed, that is, while the captured image is being displayed on the projection screen 24, the information processing apparatus 12 monitors the hold release operation by the input processing unit 66 (step S100), and determines whether there is a hold release operation. To do.

  If there is a hold release operation (YES in step S100), a hold release signal is sent from the input processing unit 66 to the projection control unit 68 (step S101). On the projection device 14 side, the projection control unit 68 receives the hold release signal from the input processing unit 66, and displays the image data coming from the transmission unit 58 on the projection screen 24 (step S102). That is, the process returns to the normal process (step S91) (step S106).

  On the information processing apparatus 12 side, a hold release signal is sent from the input processing unit 66 to the data processing unit 102 (step S103). On the projection device 14 side, the data processing unit 102 receives the hold release signal from the input processing unit 66, and transfers the image data file and the history information in the information storage unit 104 to the information storage unit 64 (step S104).

  On the information processing apparatus 12 side, the information storage unit 64 holds the image data file as a backup file (step S105), and returns to the normal processing described above (step S106).

  In the third embodiment, the same effects as those of the second embodiment described above can be obtained, and image data can be stored in the information storage unit 104 on the projection device 14 side. Can be transferred to the information storage unit 64 together with the change history and stored.

[Fourth Embodiment]

  The fourth embodiment has a configuration that enables operations such as scrolling of display information displayed on the projection apparatus and switching of display materials.

  FIG. 19 is referred to for the fourth embodiment. FIG. 19 is a flowchart illustrating an example of an information display processing procedure.

  In this embodiment, the projector 14 (FIG. 4) is provided. The projection device 14 is an example of the display unit 42 described above, and constitutes a secondary monitor. In this case, the display unit 18 constitutes a primary monitor.

  Therefore, in this processing procedure, as shown in FIG. 19, the material projection is performed by the projection device 14 (step S111). This material projection is an example of information display. After the document projection, the projection image hold operation is monitored (step S112). When the hold operation is not performed (NO in step S112), the process returns to step S111.

  When the hold operation is performed (YES in step S112), the active window is backed up (step S113). Then, the projection image 26 is displayed as read-only on the projection screen 24 (step S114).

  During the hold operation, the hold release operation is monitored (step S115), and when the hold release is not performed (NO in step S115), the process returns to step S114. When releasing the hold (YES in step S115), the projection image 26 on the projection screen 24 is changed (step S116), and the process returns to step S111.

  The information display device 2D (FIG. 20) of this embodiment also has a hold function for the projection image 26 displayed on the projection screen 24, as in the above embodiment. When the hold operation is performed on the information processing apparatus 12 (primary monitor), backup data of an active file (for example, Excel or word file) is taken, and the information storage unit 110 is configured as a read-only storage unit. Therefore, the projection device 14 (secondary monitor) opens a backup file in the information storage unit 110 and displays it on the projection screen 24 as a read-only monitor. Thereby, on the projection screen 24 (FIG. 22) of the projection device 14, the display material cannot be edited, but operations other than editing such as scrolling and switching of the display material can be performed. In short, the information storage unit 110 constitutes a backup unit for the image data source 54 that stores editable image data.

  When the hold release operation is performed, an image on the display unit 18 of the information processing apparatus 12 is displayed on the projection screen 24 of the projection apparatus 14. That is, the image on the secondary monitor is replaced with the image on the primary monitor. At this time, the image data acquired at the time of the hold operation is saved as backup data in the information storage unit 110, and the original data can be restored if the edited content is inappropriate. In this case, the backup data in the backup data file unit 112 of the information storage unit 110 may be transferred to the information storage unit 64 for backup.

  In such a configuration, by performing the hold operation, the display on the projection device 14 side is switched to an independent read-only monitor, and thus, operations such as scrolling and switching of display materials can be performed on the projection screen 24. As a result, the operability on the projection screen 24 can be improved. Since the hold operation and the hold release operation are the same as those in the third embodiment, the description thereof is omitted.

  Next, FIG. 20 is referred with respect to the function part of the information display. FIG. 20 is a diagram illustrating an example of a functional unit of the information display device. 20, the same parts as those in FIG. 14 are denoted by the same reference numerals.

  In the information display device 2D, the information storage unit 110 on the projection device 14 side includes a backup data file unit 112. The backup data file unit 112 is a data backup unit and constitutes a read-only storage unit.

  Similarly, the information storage unit 64 includes a backup data file unit 114. The backup data file unit 114 is a data backup unit and constitutes a read-only storage unit.

  The input processing unit 66 receives a hold instruction from the input unit 16 and acquires the active window or document file (backup data) from the image data displayed on the display unit 18 at that time. To instruct. At the same time, a hold notification is sent to the projection control unit 68.

  In response to the data acquisition instruction from the input processing unit 66, the data processing unit 62 transfers the acquired image data file to the backup data file unit 112 of the information storage unit 110. At this time, the transfer method includes infrared rays, a dedicated connection code, Bluetooth, and the like.

  Upon receiving a hold notification from the input processing unit 66, the data processing unit 102 of the projection device 14 confirms that the image data has been stored in the information storage unit 110, and then opens the image data file for reading only, Transfer to the control unit 68.

  The projection control unit 68 projects the image data transmitted from the data processing unit 102 by switching from the image data projection from the transmission unit 58.

  When a hold release input is input from the input unit 16, the input processing unit 66 notifies the projection control unit 68 and the data processing unit 102 of the hold release.

  The projection control unit 68 receives the hold release notification from the input processing unit 66 and switches to the projection of the image data transmitted from the information processing apparatus 12. The data processing unit 102 stores the image data held and projected in the information storage unit 110 as backup data in the backup data file unit 114 of the information storage unit 64. At this time, the image data in the information storage unit 110 may be deleted by the data processing unit 102 for security.

  Next, referring to FIG. 21 and FIG. 22, the hardware for realizing the functional unit will be described. FIG. 21 is a diagram illustrating a hardware configuration example of the information processing apparatus, and FIG. 22 is a diagram illustrating a hardware configuration example of the projection apparatus. 21 and 22, the same parts as those in FIGS. 9 and 14 are denoted by the same reference numerals.

  In order to realize such a functional unit, the information processing apparatus 12 includes a backup data storage unit 118 in a data storage unit 78 in the memory unit 74 as shown in FIG. The backup data storage unit 118 constitutes the backup data file unit 114 described above.

  Further, as shown in FIG. 22, the projection device 14 includes a backup data storage unit 120 in the image data storage unit 108 in the memory unit 106. The backup data storage unit 120 constitutes the backup data file unit 112 described above.

  Also in this information display device 2D, the display unit 18 corresponds to the primary monitor and the projection screen 24 corresponds to the secondary monitor, and the two images are not operated, and the same image is displayed on the primary monitor and the secondary monitor. For example, the projection device 14 may be a projector, but may be an external display device.

  Also in this embodiment, the input unit 16 is input means such as a keyboard or a pointing device, and the input unit 16 may be provided with a key for hold instruction. Other configurations are the same as those of the second embodiment and the third embodiment, and thus description thereof is omitted.

  Next, FIG. 23 will be referred to for information display processing procedures. FIG. 23 is a flowchart illustrating an example of a processing procedure of image data display.

  This processing procedure is an example of an information display program and method of the present disclosure. This processing procedure includes a process in which a captured image acquired by the data processing unit 62 in response to an instruction on the information processing apparatus 12 (FIGS. 4 and 9) is provided to the projection image 26 at the time of holding.

  Therefore, in this processing procedure, as shown in FIG. 23, normal processing is executed before the hold operation (step S121). As described above in the third embodiment, this normal processing refers to image data in the image data source 54 displayed on the display unit 18 according to an instruction from the input processing unit 66 (FIG. 20) before the image data is changed. And displayed on the projection screen 24. In this case, the image data provided to the display unit 18 and the projection device 14 is common, and the same image is displayed on the display unit 18 and the projection screen 24.

  During the display of the image data by the normal processing, the input processing unit 66 monitors the hold operation (step S122) and determines whether there is a hold operation. If there is no hold operation (NO in step S122), the common display image of the projection device 14 and the display unit 18 is maintained. That is, the normal process (step S121) is maintained.

  If there is a hold operation (YES in step S122), the input processing unit 66 instructs the data processing unit 62 to acquire (capture) the displayed image data from the image data source 54 at the time of the operation. (Step S123).

  The data processing unit 62 transfers the backup data file as image data to the backup data file unit 112 of the information storage unit 110 (step S124).

  Then, the input processing unit 66 sends a hold signal to the projection control unit 68 (step S125).

  The display control unit 60 displays the image data of the image data source 54 on the display unit 18, and the transmission unit 58 transmits the image data of the image data source 54 to the projection control unit 68 (step S126). The user can edit or change the image data from the input processing unit 66. Although the change of the image data is displayed on the display unit 18, since the captured image is displayed on the projection screen 24 during the change of the image data, the image data being changed and the operation thereof are not displayed.

  While the image data is being changed, that is, while the captured image is being displayed on the projection screen 24, the input processing unit 66 monitors the hold release operation (step S127), and determines whether there is a hold release operation. If the hold release operation is not performed (NO in step S127), the projection device 14 maintains the display of the captured image, and the display unit 18 displays the image data being changed.

  If there is a hold release operation in the input processing unit 66 (YES in step S127), a hold release signal is sent from the input processing unit 66 to the projection control unit 68 (step S128). A hold release signal is sent from the input processing unit 66 to the data processing unit 102 (step S129).

  The information storage unit 64 stores the data file transmitted from the data processing unit 102 as a backup data file (step S130). As a result, the image display on the display unit 18 based on the image data on the display control unit 60 side and the projection image 26 displayed on the projection screen 24 on the projection control unit 68 side are the same.

  Then, the display end of the display process is monitored (step S131). If the display end is not selected (NO in step S131), the process returns to step S121, and the above process is continuously executed. If the display is finished (YES in step S131), this process is finished.

  Next, FIG. 24 will be referred to regarding the processing procedure on the projection device 14 side. FIG. 24 is a flowchart illustrating an example of a processing procedure of image data display.

  Before the hold operation, in the projection device 14, the projection control unit 68 projects the image data of the image data source 54 on the projection screen 24 and displays it (step S141). Whether the image data file is sent from the data processing unit 62 is monitored (step S142). If the image data file is sent (YES in step S142), the information storage unit 110 holds the image data (step S143). ).

  It is monitored whether there is a hold instruction notification from the input processing unit 66 to the projection control unit 68 (step S144). If there is a hold instruction notification (YES in step S144), the projection control unit 68 receives from the input processing unit 66. In response to the hold signal, the information storage unit 110 is referred to (step S145).

  The projection control unit 68 checks whether there is an image data file in the information storage unit 110 (step S146). If there is an image data file (YES in step S146), the projection control unit 68 opens the image data file sent to the information storage unit 110 in a read-only manner, giving priority to the image data from the transmission unit 58, and the projection screen. 24 (step S147).

  It is monitored whether there is a hold release notification from the input processing unit 66 to the projection control unit 68 (step S148). If there is a hold release notification (YES in step S148), the projection control unit 68 receives the hold release signal from the input processing unit 66 and displays the image data of the image data source 54 from the transmission unit 58 on the projection screen 24. (Step S149). That is, the display is switched to display of image data from the image data source 54.

  It is monitored whether there is a hold release notification from the input processing unit 66 to the data processing unit 102 (step S150). If there is a hold release notification (YES in step S150), the data processing unit 102 receives the hold release signal from the input processing unit 66, and stores the image data file in the information storage unit 110 in the information storage unit 64 (step S150). S151).

  Next, an image display processing sequence will be described with reference to FIG. FIG. 25 is a flowchart illustrating an example of a processing sequence of image data display.

  In this processing sequence, the relevance of the processing of the information processing device 12 and the projection device 14 is mentioned with respect to the above-described processing procedures of the information processing device 12 and the projection device 14 (FIGS. 23 and 24).

  Therefore, the information processing device 12 and the projection device 14 execute the normal processing described above (step S161). During the display of the image data by the normal processing, the information processing apparatus 12 monitors the hold operation by the input processing unit 66 (step S162) and determines whether there is a hold operation. If there is no hold operation (NO in step S162), the normal process (step S161) is maintained.

  If there is a hold operation (YES in step S162), at the time of the operation, the input processing unit 66 instructs the data processing unit 62 to take a backup data file of the image data source 54 (step S163).

  The data processing unit 62 transfers the image data file to the information storage unit 110 (step S164). In response to this, in the projection device 14, the information storage unit 110 holds the image data file (step S165).

  Then, the input processing unit 66 of the information processing apparatus 12 sends a hold signal to the projection control unit 68 and the data processing unit 102 (step S166). On the projection device 14 side, the data processing unit 102 receives the hold signal from the input processing unit 66 and refers to the information storage unit 110 (step S167).

  After confirming that there is image data in the information storage unit 110, the data processing unit 102 opens the corresponding image data file for reading only (step S168). The projection control unit 68 displays the image data from the data processing unit 102 on the projection screen 24 with priority over the image data from the transmission unit 58 (step S169).

  While the image data is being changed, that is, while the captured image is being displayed on the projection screen 24, the input processing unit 66 monitors the hold release operation (step S170), and determines whether there is a hold release operation.

  If there is a hold release operation (YES in step S170), a hold release signal is sent from the input processing unit 66 to the projection control unit 68 (step S171). On the projection device 14 side, the projection control unit 68 receives the hold release signal from the input processing unit 66, and displays the image data from the transmission unit 58 on the projection screen 24 (step S172). That is, the process returns to the normal process (step S161) (step S176).

  On the information processing apparatus 12 side, a hold release signal is sent from the input processing unit 66 to the data processing unit 102 (step S173). On the projection device 14 side, the data processing unit 102 receives the hold release signal from the input processing unit 66, and transfers the image data file in the information storage unit 110 to the information storage unit 64 (step S174).

  On the information processing apparatus 12 side, the information storage unit 64 holds the image data file as a backup file (step S175), and returns to the normal processing described above (step S176).

  Also in the fourth embodiment, the effects shown in the second embodiment can be obtained, and the image data stored as the backup data file backs up the image data source 54 for storing rewritable image data. it can. Thereby, the preservation | save property of image data can be improved.

[Comparative example]

  In a conference using a projection device that projects image information, an image is projected in real time. In this case, other operations have been performed on the terminal while projecting only the specific material by the two-screen operation. However, when editing the material being projected, the editing operation cannot be hidden. For this reason, when it is necessary to make changes to the material on the spot, all operations including security operations are always seen by the surrounding people, and it is lacking in safety such as information leakage. Since all operations such as typing can be seen, in the event of a mistake, not only the operator but also other participants are uncomfortable. In addition, when performing an exclusive operation such as changing the projection material, all attendees are waiting time during this time.

  Therefore, a system is constructed in which the projection screen is held once when changing the data on the secondary monitor, and the projection screen is switched to the changed screen after the change is confirmed on the primary monitor (terminal). In this case, there are the following three major projection methods using a secondary monitor. First, when it is set to be able to move on the primary monitor and the secondary monitor, second, when the same screen is displayed on the primary monitor and the secondary monitor, and thirdly, only on the secondary monitor This is the case.

  In the first case, since the primary monitor and the secondary monitor are different displays, there is no need to display a dummy in the first place. In the second case, the information being changed is displayed on the secondary monitor, which is a problem. In the third case, operability from the terminal side is also low, and this method is rarely used for presentations.
