FIG. 4 is a flowchart illustrating display processing according to the embodiment, and FIG. 4 is a diagram illustrating the display processing.

  As shown in FIG. 1, the display system S1 according to the first embodiment includes a server device SV1, a terminal device T1, a terminal device T2,..., A terminal device Tn (n is a natural number), a terminal device T1, a terminal device T2, .., A camera Cn corresponding to the terminal device Tn, and a network NW such as a wireless local area network (LAN) or a wired LAN. In the following description, when the items common to the terminal device T1, the terminal device T2,..., The terminal device Tn are described, these are collectively referred to as “terminal device T”. Similarly, when the matters common to the camera C1, the camera C2,..., The camera Cn are described, these are collectively referred to as “camera C”.

  In the above configuration, each terminal device T is fixedly installed as a wall-hanging type, for example. The server device SV1 records display data to be displayed on each terminal device T. And server apparatus SV1 transmits the said display data with the timing set beforehand via the network NW with respect to the terminal device T with which it should be displayed. As a result, each terminal device T receives the display data transmitted from the server device SV1, and displays an image corresponding to the display data on a display described later included in each terminal device T.

  On the other hand, each terminal device T responds to the terminal device T with a shooting instruction Sc indicating that the image should be shot from the outside of the terminal device T while displaying the image corresponding to the display data transmitted to each terminal device T. Send to camera C. Here, the camera C to which the terminal device T corresponds refers to a camera C that includes in its shooting range a display screen on which the image is displayed. As a result, when the shooting instruction Sc is transmitted from the terminal device T to which each camera C corresponds, each camera C captures the image displayed on the terminal device T to which each camera C corresponds. Then, shooting data Scd corresponding to the shooting result is generated and transmitted to the corresponding terminal device T. Each terminal device T, when the shooting data Scd is transmitted from the corresponding camera C, transmits the shooting data Scd to the server device SV1 via the network NW.

  Next, when the shooting data Scd is transmitted from any of the terminal devices T, the server SV1 receives a shooting result corresponding to the shooting data Scd and display data corresponding to the shot image (that is, the terminal). Display data transmitted to the device T). Then, based on the comparison result, the server apparatus SV1 determines whether or not an afterimage unique to electronic paper constituting the display of the terminal apparatus T is included in the image. Thereafter, the server apparatus SV1 refreshes the terminal apparatus T that has transmitted the shooting data Scd corresponding to the shooting result of shooting the image including the afterimage to refresh the electronic paper of the terminal apparatus T. The signal and the display data corresponding to the shooting data Scd are transmitted via the network NW. In this case, the display data is retransmitted.

  Thus, the terminal device T to which the refresh signal and the display data are transmitted refreshes the electronic paper constituting the display based on the refresh signal, and then displays an image corresponding to the retransmitted display data. indicate.

  Next, detailed configurations of the server device SV1 and each terminal device T will be described with reference to FIG.

  As shown in FIG. 2A, the server apparatus SV1 according to the first embodiment includes a recording unit 1 composed of an HDD (Hard Disc Drive) or an SSD (Solid State Drive), a CPU, and a ROM (Read Only Memory). And a processing unit 2 including a RAM (Random Access Memory), an operation unit 3 including a keyboard or a mouse, a display unit 4 including a liquid crystal display, and an interface 5. At this time, the interface 5 corresponds to an example of a “server device transmission unit” according to the present invention, and the processing unit 2 corresponds to an example of a “determination unit” according to the present invention.

  In this configuration, the recording unit 1 records the display data to be transmitted to each terminal device T in a nonvolatile manner so that the database 1D including the data for each terminal device T can be read from the processing unit 2. On the other hand, the interface 5 controls transmission / reception of data between the server apparatus SV1 and each terminal apparatus T via the network NW under the control of the processing unit 2. On the other hand, when an operation for instructing the operation or the like of the server device SV1 is executed in the operation unit 3, the operation unit 3 generates an operation signal corresponding to the operation and outputs the operation signal to the processing unit 2. Accordingly, the processing unit 2 transmits the display data to the corresponding terminal device T. In addition, when the shooting data Scd is transmitted from any of the terminal devices T, the processing unit 2 compares the corresponding shooting result with the display data corresponding to the shooting data Scd and displays the result on the terminal device T. It is determined whether the afterimage is included in the image. When the afterimage is included in the image, the processing unit 2 transmits the refresh signal and transmits the display data to the terminal device T that has transmitted the shooting data Scd corresponding to the shooting result of shooting the image. Re-send.

  Next, as shown in FIG. 2B, the terminal device T according to the first embodiment includes a display 10 that uses the electronic paper as a display medium, a processing unit 11 that includes a CPU, ROM, RAM, and the like, and operation buttons. And the like, and an interface 13. At this time, the display 10 corresponds to an example of a “display unit” according to the present invention, and the interface 13 corresponds to an example of a “state information acquisition unit” and an example of a “state information transmission unit” according to the present invention. The unit 11 corresponds to an example of a “control unit” according to the present invention.

  In this configuration, the interface 13 controls data exchange between the terminal device T and the server device SV1 via the network NW under the control of the processing unit 11. On the other hand, when an operation for instructing the operation or the like of the terminal device T is executed in the operation unit 12, the operation unit 12 generates an operation signal corresponding to the operation and outputs the operation signal to the processing unit 11. Accordingly, when the display data is transmitted from the server device SV1, the processing unit 11 receives the display data and displays it on the display 10. For example, the processing unit 11 receives the new display data and generates the shooting instruction Sc at a timing when the corresponding image is displayed on the display 10, and transmits it to the corresponding camera C. When the shooting data Scd corresponding to the shooting instruction Sc is transmitted from the camera C, it is transmitted to the server SV1. When the refresh signal is transmitted from the server SV1 and the display data is retransmitted, the processing unit 11 first refreshes the electronic paper on the display 10 using the refresh signal, and then retransmits the display data. An image corresponding to the displayed display data is displayed on the display 10 again.

  Next, the display processing according to the first embodiment will be described collectively with reference to FIGS. 3 and 4. In each of the terminal devices T, the same display process is performed.

  First, in the server apparatus SV1, for example, the display process according to the first embodiment is started with the processing unit 2 as the center at the timing when the power is turned on. That is, as illustrated in FIG. 3, the processing unit 2 of the server device SV <b> 1 is configured to transmit the display data for each terminal device T after the start of the display processing according to the first embodiment. Display data to be transmitted to the terminal device T is transmitted to the terminal device T via the network NW (step S1). Thereafter, the processing unit 2 monitors whether or not the photographing data Scd corresponding to the photographing result of the image corresponding to the display data has been received from the terminal device T that has transmitted the display data (step S2). If no photographing data Scd is received from any terminal device T (step S2: NO), the processing unit 2 proceeds to step S6 described later.

  On the other hand, in each of the terminal devices T, for example, the display processing according to the first embodiment is started with the processing unit 11 as the center at the timing when the power is turned on. That is, as shown in FIG. 3, the processing unit 11 of each terminal device T monitors the reception of the display data from the server device SV1 after the start of the display processing according to the first embodiment (step S10). When display data is not received in step S10 (step S10: NO), the processing unit 11 proceeds to step S17 described later. On the other hand, when display data is received in step S10 (step S10: YES), the processing unit 11 displays the received display data using the display 10 (step S11). Thereafter, the processing unit 11 transmits the shooting instruction Sc to the effect that the image on the display 10 corresponding to the display data should be shot to the camera C corresponding to the terminal device T (step S12). Thereafter, the processing unit 11 monitors whether or not the shooting data Scd corresponding to the shooting instruction Sc is received from the camera C that has transmitted the shooting instruction Sc (step S13). If there is no reception of the shooting data Scd from the corresponding camera C (step S13: NO), the processing unit 11 continues to monitor reception of the shooting data Scd.

  On the other hand, in each camera C corresponding to each terminal device T, for example, the power is turned on, and the display processing according to the first embodiment is started from the timing. That is, as shown in FIG. 3, each camera C monitors the reception of the shooting instruction Sc from the corresponding terminal device T after the start of the display process according to the first embodiment (step S20). When the shooting instruction Sc is not received in step S20 (step S20: NO), each camera C proceeds to step S23 described later. On the other hand, when the shooting instruction Sc is received in step S20 (step S20: YES), each camera C is displayed on the display 10 of the terminal device T to which the camera C corresponds based on the received shooting instruction Sc. An image (that is, an image corresponding to display data) is photographed (step S21). Next, each camera C generates the shooting data Scd corresponding to the shooting result and transmits it to the corresponding terminal device T (step S22). Thereafter, each camera C determines whether or not to end the display processing according to the first embodiment as each camera C, for example, when the power is turned off (step S23). When the display process ends in the determination of step S23 (step S23: YES), each camera C ends the display process as it is. On the other hand, when the display process is continued in the determination in step S23 (step S23: NO), each camera C returns to step S20 and continues the display process described above.

  Next, when the processing unit 11 of each terminal device T that is monitoring in step S13 receives the shooting data Scd from the corresponding camera C in the monitoring (step S13: YES), the received shooting data Scd is transmitted to the server device SV1 via the network NW (step S14). Thereafter, each processing unit 11 monitors whether or not the refresh signal is transmitted and the display data is retransmitted from the server device SV1 (step S15). When there is no transmission of the refresh signal or the like in the monitoring in step S15 (step S15: NO), each processing unit 11 performs display processing according to the first embodiment as the terminal device T, for example, when the power is turned off. It is determined whether or not to end (step S17). When the display process ends in the determination of step S17 (step S17: YES), each processing unit 11 ends the display process as it is. On the other hand, when the display process is continued in the determination in step S17 (step S17: NO), each processing unit 11 returns to step S10 and continues the display process described above.

  On the other hand, when the processing unit 2 of the server apparatus SV1 that monitors in step S2 receives the shooting data Scd from any of the terminal devices T (step S2: YES), the shooting result corresponding to the shooting data Scd is received. Are compared with display data corresponding to images taken by the corresponding camera C (step S3). Next, the processing unit 2 responds to the captured data Scd as a determination as to whether or not the display quality of the display 10 of the terminal device T that has transmitted the captured data Scd is good based on the comparison result of step S3. It is determined whether the afterimage is included in the image corresponding to the display data (step S4).

  Here, a specific example of the afterimage will be described with reference to FIG. That is, for example, after the image G1 illustrated on the left in FIG. 4A is displayed on the display 10, the image G1 is switched to another image G2 based on other display data (see the right in FIG. 4A). Think about the case. At this time, the image G1 is an image including the character string “ABC”, and the image G2 is an image including another character string “XYZ” at a position different from the position of the character string “ABC” in the image G1. When the afterimage occurs in the electronic paper according to the first embodiment, as illustrated on the right side of FIG. 4A, the image G2 corresponding to the position where the character string “ABC” was displayed in the image G1. At the position, the character string “ABC” before switching is displayed lightly as an afterimage ZG (the display remains). Therefore, in the determination in step S4, the processing unit 2 determines whether or not an afterimage ZG as illustrated in FIG. 4 is included.

  If it is determined in step S4 that the afterimage ZG is not included, that is, it is determined that the display quality of the display 10 of the terminal device T that has transmitted the shooting data Scd is good (step S4: YES). Next, the processing unit 2 determines whether or not to end the display process according to the first embodiment as the server apparatus SV, for example, when the power is turned off (step S6). When the display process is ended in the determination in step S6 (step S6: YES), the processing unit 2 ends the display process as it is. On the other hand, when the display process is continued in the determination in step S6 (step S6: NO), the processing unit 2 returns to step S1 and continues the display process as the server apparatus SV1 described above. On the other hand, if the afterimage ZG is included in the determination in step S4, that is, if it is determined that the display quality of the display 10 of the terminal device T that has transmitted the shooting data Scd is not good (step S4: NO). The processing unit 2 transmits the refresh signal via the network NW and transmits the refresh signal to the terminal device T that has transmitted the photographing data Scd corresponding to the photographing result obtained by photographing the image including the afterimage ZG. The display data is retransmitted (step S5). Thereafter, the processing unit 2 proceeds to step S6.

  Next, when there is a transmission of the refresh signal and a re-transmission of the display data in the monitoring in step S15 (step S15: YES), the processing unit 11 of each terminal device T The electronic paper constituting the display 10 is refreshed (step S16).

  Here, the refresh of the electronic paper will be specifically described with reference to FIG. When it is found that the afterimage ZG is included in the display using the electronic paper as a display medium (see NO in step S4 in FIG. 3), the processing unit 11 of each terminal device T receives the refresh signal. Based on the electronic paper refresh. In this refresh, if the processing unit 11 of each terminal device T displays, for example, the image G1 shown on the left in FIG. 4A on the display 10, it will be exemplified in FIG. 4B instead of the image G1. The black image B of black and the white image W of white are alternately displayed within a preset time (see the portion surrounded by the broken line in FIG. 4B). Each processing unit 11 refreshes the electronic paper constituting the display 10 by performing this black and white alternate display a predetermined number of times within the predetermined time (step S16). Thereafter, for example, when an image G2 shown in the lower right of FIG. 4A is displayed, the afterimage ZG corresponding to the character string “ABC” in the original image G1 disappears as an effect of the refresh.

  Thereafter, each processing unit 11 shifts to step S11 to display the display data again using the display 10 using the retransmitted display data. Thereafter, each processing unit 11 repeats the display processing according to the first embodiment as each terminal device T described above.

  As described above, according to the display processing according to the first embodiment, when the display data transmitted from the server apparatus SV1 connected to each terminal apparatus T is displayed on the terminal apparatus T, the terminal apparatus Shooting data Scd indicating the display state at T is acquired by the terminal device T, and the display 10 is controlled (refreshed) in correspondence with the shooting data Scd. Therefore, according to the display state, the display data can be displayed on the terminal device T in an easy-to-see manner.

  In addition, when the terminal device T acquires the photographing data Scd indicating the display state (that is, the presence or absence of an afterimage) of the electronic paper as the display medium and transmits it to the server device SV1, the electronic paper is displayed when the refresh signal is received from the server device SV. Refresh. On the other hand, when the server apparatus SV1 receives the shooting data Scd from the terminal apparatus T, the server apparatus SV1 determines whether or not the electronic paper is in a display state that requires refreshing. A refresh signal is transmitted to the terminal device T that has transmitted the data Scd. Therefore, the display state of the electronic paper can always be maintained satisfactorily.

  Furthermore, since the shooting data Scd is shooting data obtained by shooting the display surface of the display 10, it is possible to determine the necessity of refresh based on the actual display state.

  That is, as shown in FIG. 5, the display system S2 according to the second embodiment includes a server device SV2, a terminal device TT1, a terminal device TT2,..., A terminal device TTn, a terminal device TT1, a terminal device TT2,. The illuminance sensor LS1, the illuminance sensor LS2,..., The illuminance sensor LSn respectively corresponding to the devices TTn, and the network NW similar to the first embodiment are configured. In the following description, when the items common to the terminal device TT1, the terminal device TT2,..., The terminal device TTn are described, these are collectively referred to as “terminal device TT”. Similarly, when the matters common to the illuminance sensor LS1, the illuminance sensor LS2,..., The illuminance sensor LSn are described, these are collectively referred to as “illuminance sensor LS”.

  In the above configuration, each terminal device TT is fixedly installed, for example, as a wall-hanging type like each terminal device T according to the first embodiment, and the server device SV2 displays display data to be displayed on each terminal device TT. It is recorded. Similarly to the server apparatus SV1 according to the first embodiment, the server apparatus SV2 transmits the display data to the terminal apparatus TT on which it is to be displayed via the network NW, and each terminal apparatus TT Each of the display data is received, and an image corresponding to the display data is displayed on a display included in each terminal device TT.

  On the other hand, each terminal device TT displays a measurement instruction Scc indicating that the illuminance of the environment in which each terminal device TT is placed should be measured while displaying the image corresponding to the display data transmitted to each terminal device TT. Transmit to the illuminance sensor LS corresponding to the device TT. Here, the illuminance sensor LS to which the terminal device TT corresponds refers to the illuminance sensor LS that includes the environment in which the terminal device TT is placed in the illuminance measurement range. Accordingly, when each of the illuminance sensors LS receives the measurement instruction Scc from the corresponding terminal device TT, the illuminance of the environment where the corresponding terminal device TT is placed is based on the measurement instruction Scc. , Illuminance data Scl corresponding to the measurement result is generated and transmitted to the corresponding terminal device TT. Then, when the illuminance data Scl is transmitted from the corresponding illuminance sensor LS, each terminal device TT transmits the illuminance data Scl to the server device SV2 via the network NW.

  Next, when the illuminance data Scl is transmitted from any one of the terminal devices TT, the server SV2 receives the illuminance indicated by the illuminance data Scl and displays the display data in the terminal device TT in the environment having the illuminance. It is determined whether or not the display color pattern is appropriate. In this case, the display color pattern refers to a gradation data pattern or a color data pattern when an image corresponding to display data on the display 10 of the terminal device TT is displayed. Thereafter, the server apparatus SV2 transmits (new) display data in which the display color pattern is optimized to the terminal apparatus TT whose display color pattern is not appropriate via the network NW.

  Thereby, the terminal device TT to which the new display data is transmitted displays an image corresponding to the new display data.

  Next, the configuration of the server device SV2 will be described with reference to FIG. The hardware configuration of each terminal device TT according to the second embodiment is basically the same as the hardware configuration of each terminal device T according to the first embodiment. Description is omitted. In contrast, the hardware configuration of the server apparatus SV2 according to the second embodiment is different from that of the server apparatus SV1 according to the first embodiment in the database 1D according to the first embodiment. In addition, the difference is that the database 1D2 according to the second embodiment is recorded in the recording unit 1. Note that other points in the hardware configuration of the server apparatus SV2 according to the second embodiment are basically the same as the hardware configuration of the server apparatus SV1 according to the first embodiment.

  Specifically, in the database 1D2 according to the second embodiment recorded in the recording unit 1, the database DB1 and the database DB2 are recorded in a nonvolatile manner as illustrated in FIG.

  At this time, in the database DB1, a pattern value indicating a display color pattern at that time on the display 10 is recorded for each image ID for identifying an image corresponding to display data transmitted to each terminal device TT. Specifically, in the case illustrated in FIG. 6A, the image with the image ID “1” and the image with the image ID “2” have the display color pattern “pattern A” at that time, and “3 The image with the image ID “” has the display color pattern “pattern B” at that time.

  On the other hand, in the database DB2, for each illuminance value indicated by the illuminance data Scl, there is a parameter value indicating a display color pattern that is preset as appropriate when displaying an image on the display 10 in the environment of the illuminance. It is recorded. Specifically, in the database DB2 illustrated in FIG. 6B, when the illuminance indicated by the illuminance data Scl is “1000”, it is appropriate to set the display color pattern to “pattern A”. 750 ”, it is appropriate to set the display color pattern to“ pattern B ”, and when the illuminance is“ 500 ”, it is appropriate to set the display color pattern to“ pattern C ”. , Each is recorded. And the process part 2 of server apparatus SV2 which concerns on 2nd Embodiment is transmitted to the terminal device TT in the environment which has the illumination intensity with respect to the illumination intensity shown with the illumination intensity data Scl from any terminal device TT. It is determined with reference to the database DB2 whether or not the display color pattern of the display data is appropriate. And server apparatus SV2 transmits the new display data which optimized the said display color pattern with respect to the terminal device TT whose said display color pattern is not appropriate.

  Next, display processing according to the second embodiment will be described collectively with reference to FIGS. 7 and 8. Each terminal device TT performs the same display process. In FIG. 7, processes similar to those of the display system S <b> 1 according to the first embodiment are denoted by the same step numbers, and detailed description thereof is omitted.

  First, in the server apparatus SV2, for example, the display process according to the second embodiment starts with the processing unit 2 as the center at the timing when the power is turned on. That is, as illustrated in FIG. 7, the processing unit 2 of the server apparatus SV performs step S <b> 1 of the display process (see FIG. 3, the same applies hereinafter) according to the first embodiment after the display process according to the second embodiment is started. Similar processing is performed. Thereafter, the processing unit 2 monitors whether or not the illuminance data Scl indicating the illuminance of the environment in which the terminal device TT is received is received from the terminal device TT that transmitted the display data (step S30). When no illuminance data Scd is received from any terminal device TT (step S30: NO), the processing unit 2 proceeds to the same processing as step S6 of the display processing according to the first embodiment.

  On the other hand, in each of the terminal devices TT, for example, the display process according to the second embodiment is started centering on the processing unit 11 from the timing when the power is turned on. That is, as illustrated in FIG. 7, the processing unit 11 of each terminal device TT performs the same processing as Step S10 and Step S11 of the display processing according to the first embodiment after the display processing according to the second embodiment is started. Do. Thereafter, each processing unit 11 transmits a measurement instruction Scc to the effect that the illuminance of the environment where the terminal device TT is placed is measured to the illuminance sensor LS corresponding to the terminal device TT (step S35). Thereafter, each processing unit 11 monitors whether or not the illuminance data Scl corresponding to the measurement instruction Scc has been received from the illuminance sensor LS that has transmitted the measurement instruction Scc (step S36). If no illuminance data Scl is received from the corresponding illuminance sensor LS (step S36: NO), each processing unit 11 continues to monitor reception of the illuminance data Scl.

  On the other hand, in each illuminance sensor LS corresponding to each terminal device TT, for example, the power is turned on, and the display processing according to the second embodiment is started from the timing. That is, as shown in FIG. 7, each illuminance sensor LS monitors the reception of the measurement instruction Scc from the terminal device TT to which it corresponds after the display process according to the second embodiment is started (step S40). When the measurement instruction Scc is not received in step S40 (step S40: NO), each illuminance sensor LS shifts to a process similar to step S23 of the display process according to the first embodiment. On the other hand, when the measurement instruction Scc is received in step S40 (step S40: YES), each illuminance sensor LS is provided with the terminal device TT to which the illuminance sensor LS corresponds based on the received measurement instruction Scc. The illuminance of the environment is measured (step S41). Thereafter, each illuminance sensor LS generates the illuminance data Scl corresponding to the measurement result and transmits it to the corresponding terminal device TT (step S42). Thereafter, each illuminance sensor LS shifts to a process similar to step S23 of the display process according to the first embodiment.

  Next, when the processing unit 11 of each terminal device TT that is monitoring in step S36 receives the illuminance data Scl from the corresponding illuminance sensor LS in the monitoring (step S36: YES), the received imaging Data Scd is transmitted to server apparatus SV via network NW (step S37). Thereafter, each processing unit 11 shifts to a process similar to step S17 of the display process according to the first embodiment.

  On the other hand, when the processing unit 2 of the server SV2 that is monitoring in step S30 receives the illuminance data Scl from any one of the terminal devices TT (step S30: YES), the terminal device that has transmitted the illuminance data Scl. The parameter value of the display color pattern in the image corresponding to the display data transmitted to the TT (see step S1 and step S10) is acquired with reference to the database DB1 (step S31). Next, the processing unit 2 checks a display color pattern appropriate for the illuminance indicated by the illuminance data Scl with reference to the database DB2 (step S32). Thereafter, the processing unit 2 compares the confirmation result in step S32 with the parameter value acquired in step S31, and the display color pattern corresponding to the parameter value acquired in step S31 is the illuminance indicated by the illuminance data Scl. It is determined whether or not the display color pattern is appropriate (step S33). If the display color pattern corresponding to the parameter value acquired in step S31 is an appropriate display color pattern in the determination in step S33 (step S33: YES), the processing unit 2 next displays the display according to the first embodiment. The process proceeds to the same process as step S6 of the process.

  On the other hand, when the display color pattern corresponding to the parameter value acquired in step S31 is not an appropriate display color pattern in the determination in step S33 (step S33: NO), the processing unit 2 next refers to the database DB2. Only the display color pattern of the display data transmitted in step S1 is optimized (that is, the image content corresponding to the display data is not changed), and new display data is regenerated (step S34). Here, in the regeneration of the display data in step S34, when the display color pattern before optimization is, for example, that shown in FIG. 8A, the contrast is higher in the illuminance environment indicated by the illuminance data Scl, for example. When a strong display color pattern is appropriate, the display color pattern is changed (optimized) to, for example, the display color pattern shown in FIG. 8B (that is, a display color pattern with strong contrast).

  Thereafter, the processing unit 11 returns to step S1, transmits the regenerated display data (see step S34) to the terminal device TT that has transmitted the illuminance data Scl, and further performs the second embodiment described above. The display process according to the form is continued.

  As described above, according to the display processing according to the second embodiment, when display data transmitted from the server apparatus SV2 connected to each terminal apparatus TT is displayed on the terminal apparatus TT, the terminal apparatus The terminal device TT acquires illuminance data Scl indicating the illuminance in the environment where the TT is placed, and controls the display color pattern on the display 10 in correspondence with the illuminance data Scl. Therefore, the display data can be easily displayed on the terminal device TT according to the environment in which it is placed.
