DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] [System Overview] 1 is a block diagram showing an example of the configuration of an information display system 100 according to an embodiment. The information display system 100 includes a plurality of unit sets 1A and 1B. The number of unit sets 1A and 1B is not limited to two, and there may be three or more.

[0016] In this embodiment, a plurality of unit sets 1A, 1B are mounted on a plurality of ships SH1, SH2, respectively.

[0017] Each of the plurality of unit sets 1A and 1B includes an information processing device 10, a wireless communication unit 11, a display unit 12, an operation unit 13, and a video generating unit .

[0018] The information processing device 10 is a computer including a CPU, a RAM, a ROM, a non-volatile memory, an input / output interface, etc. The CPU of the information processing device 10 executes information processing according to a program loaded from the ROM or the non-volatile memory to the RAM.

[0019] The program may be supplied via an information storage medium such as an optical disk or a memory card, or may be supplied via a communication network such as the Internet or a LAN.

[0020] The wireless communication unit 11 is connected to the antenna 11a and enables wireless communication between the unit sets 1A and 1B. That is, the wireless communication unit 11 enables the information processing devices 10 to communicate with each other.

[0021] The wireless communication by the wireless communication unit 11 may be, for example, direct wireless communication using a wireless LAN based on IEEE 802.11, or may be, for example, indirect wireless communication via a base station using a mobile communication system such as LTE.

[0022] The display unit 12 is, for example, a display device such as a liquid crystal display or an organic EL display, etc. The operation unit 13 is, for example, a pointing device such as a touch panel or a trackball.

[0023] The video generating unit 14 is a device that generates video data, such as a radar device, a fish finder, a sonar, or a plotter device. The video data is data that is displayed moment by moment on the display unit of each device. There may be multiple video generating units 14.

[0024] The radar device emits microwaves using an antenna, receives the reflected waves, and generates radar information based on the received signals. The radar information includes information on the distance and direction of targets around the ship. The radar device generates video data based on the radar information.

[0025] A fish finder and a sonar emit ultrasonic waves into the water using an ultrasonic transducer installed on the bottom of a ship, receive the reflected waves, and generate underwater detection information based on the received signals. The underwater detection information includes information on schools of fish and the seabed. The fish finder generates video data based on the underwater detection information.

[0026] The plotter device calculates the position of the ship based on radio waves received from a Global Navigation Satellite System (GNSS), generates plot information that plots the position of the ship on an electronic chart, and generates video data based on the plot information.

[0027] Fig. 2 is a diagram showing a display example of the screen 30 of the display unit 12. Fig. 3 is a diagram showing an example of a screen division table for displaying the screen 30. The screen division table is read from the non-volatile memory when the information processing device 10 is started up, and is used for displaying the screen 30.

[0028] 2, the screen 30 is divided into one main area M and multiple sub-areas S1 to S3. The main area M is an area for displaying in real time video data generated by a video generating unit 14 of the ship or another ship.

[0029] The sub-areas S1 to S3 are areas for sequentially displaying time-series image data generated on the own ship or other ships based on video data. The main area M displays video data corresponding to image data selected from the sub-areas S1 to S3.

[0030] The number and positions of the sub-regions S1 to S3 are not limited to the example shown in the drawing. Furthermore, the number and positions of the sub-regions S1 to S3 may be changeable by the user.

[0031] 3, in the screen division table, the main area M and the sub-areas S1 to S3 are associated with a source and a location of video data. The source of the video data represents the video generation unit 14. The location of the source represents the ship on which the video generation unit 14 is installed.

[0032] In the illustrated example, video data from the ship's radar device is displayed in the main area M, image data from the ship's radar device is displayed in the sub-area S1, image data from the fish finder of another ship 1 is displayed in the sub-area S2, and image data from the plotter device of another ship 2 is displayed in the sub-area S3.

[0033] 4 is a block diagram showing an example of the configuration of the information processing device 10 according to the embodiment. The information processing device 10 includes a video acquisition unit 21, an image generation unit 22, a transmission processing unit 23, a display control unit 24, a video request unit 25, a drawing generation unit 26, a display request unit 27, and an audio transmission / reception unit 28.

[0034] These functional units are realized by the CPU of the information processing device 10 executing information processing in accordance with a program loaded from the ROM or non-volatile memory to the RAM.

[0035] In this embodiment, the information processing device 10 includes these functional units, and thereby functions as both the first information processing device and the second information processing device described above.

[0036] The video acquisition unit 21 acquires video data from a video generation unit 14 such as a radar device, a fish finder, a sonar, or a plotter device (on the ship itself) connected to the information processing device 10.

[0037] The image generating unit 22 generates a plurality of time-series image data having a smaller amount of data than the video data based on the video data acquired by the video acquiring unit 21.

[0038] The transmission processing unit 23 sequentially transmits the time-series image data generated by the image generating unit 22 to the other information processing device 10. Furthermore, the transmission processing unit 23 transmits moving image data to the other information processing device 10 in response to a moving image request.

[0039] The display control unit 24 displays moving image data in a main area M divided within a screen 30 of the display unit 12, and sequentially displays time-series image data in sub-areas S1 to S3 (see FIGS. 2 and 3).

[0040] When an operation of selecting one of the sub-areas S1 to S3 is detected, the video request unit 25 transmits a video request for requesting video data to the other information processing device 10. That is, the video request includes information indicating which source has been selected as the video data to be displayed in the main area M.

[0041] The drawing generation unit 26 generates drawing data representing an image drawn in the main region M by a user operation, and transmits the drawing data to the other information processing device 10.

[0042] The display request unit 27 transmits a display request that specifies the video data to be displayed in the main region M to the other information processing device 10.

[0043] The voice transmitting / receiving unit 28 transmits and receives voice data input by a user. Voice data input from a microphone (not shown) is transmitted to the other information processing device 10, and voice data received from the other information processing device 10 is output from a speaker (not shown).

[0044] [Toggle main area display] Hereinafter, a process relating to switching of the display of the main region M in the information processing method according to the embodiment, which is realized in the information processing device 10, will be described.

[0045] 5 is a diagram for explaining switching of display in the main region M. The sub-regions S1 to S3 are made into buttons, and can be selected by the user. The user may select by touching or clicking, for example.

[0046] When one of the sub-areas S1 to S3 is selected, the main area M displays video data corresponding to the image data displayed in the selected sub-area.

[0047] Specifically, when a sub-area that displays image data received from another information processing device 10 is selected, video data corresponding to the image data is obtained from the other information processing device 10 and displayed in the main area M.

[0048] 6 and 7 are flow diagrams showing an example of a procedure for switching the display of the main region M. The information processing device 10 executes the information processing shown in the figures according to a program, thereby functioning as a video acquisition unit 21, an image generation unit 22, a transmission processing unit 23, a display control unit 24, and a video request unit 25.

[0049] In the description of this example, the information processing device 10 that provides the video data is referred to as a “first information processing device,” and the information processing device 10 that receives the video data is referred to as a “second information processing device.” The information processing device 10 of each ship can be either the first information processing device or the second information processing device.

[0050] As shown in FIG. 6, first, the first information processing device acquires moving image data from the moving image generating unit 14 (see FIG. 1) (S11: processing as the moving image acquiring unit 21).

[0051] Next, the first information processing device generates time-series image data having a smaller amount of data than the video data, based on the acquired video data (S12: processing as the image generating unit 22).

[0052] The time-series image data is generated by, for example, reducing at least one of the resolution and the frame rate of the video data. The time-series image data may be divided into individual image data or may be collected into a single file like the video data.

[0053] Next, the first information processing device transmits the generated time-series image data to the second information processing device in sequence (S13: processing as the transmission processing unit 23).

[0054] Specifically, the second information processing device periodically transmits a request for image data to be displayed in the sub-area to the first information processing device, and the first information processing device transmits time-series image data in sequence to the second information processing device.

[0055] When the second information processing device receives time-series image data from the first information processing device, it displays the received time-series image data in sequence in the sub-area defined in the screen division table (see FIG. 3) (S21: processing as the display control unit 24).

[0056] Next, when the second information processing device detects a user operation of selecting a sub-area in which time-series image data is displayed (S22: YES), it sends a video request to the first information processing device to request video data (S23: processing as video request unit 25).

[0057] When the first information processing device receives the video request from the second information processing device (S14: YES), it transmits video data to the second information processing device (S15: processing as the transmission processing unit 23). Note that even after starting to transmit the video data, the first information processing device continues generating and transmitting time-series image data.

[0058] When the second information processing device receives the video data from the first information processing device, the second information processing device displays the received video data in the main area (S24: processing as the display control unit 24).

[0059] 7, next, when an operation to cancel the display of the video data in the main region is detected (S25: YES), the second information processing device transmits a stop request to stop transmission of the video data to the first information processing device (S26: processing as the video request unit 25). The operation to cancel the display is, for example, a user operation to select another sub-region.

[0060] When the first information processing device receives the stop request from the second information processing device (S16: YES), the first information processing device stops transmitting the video data (S17: processing as the transmission processing unit 23). Note that even if the first information processing device stops transmitting the video data, it continues generating and transmitting the time-series image data.

[0061] As described above, by limiting the display destination of video data to the main area and sequentially displaying time-series image data, which has a smaller amount of data than the video data, in the sub-area, it is possible to reduce network bandwidth usage.

[0062] In addition, by switching the video data displayed in the main area when a sub-area is selected by user operation, the switching operation can be performed easily and intuitively compared to, for example, switching after displaying a menu screen.

[0063] In addition, by displaying the image data in chronological order in the sub-areas, it is possible to roughly grasp the state of each video data while keeping the amount of data down. This makes it possible to comprehensively grasp the information obtained from each vessel and improve the efficiency of fishing operations.

[0064] [User-drawn] Hereinafter, a process relating to drawing by a user, which is implemented in the information processing device 10 and is included in the information processing method according to the embodiment, will be described.

[0065] 8 is a diagram for explaining drawing by a user. The main area M is available for drawing by the user. That is, an image DM drawn by the user is added to an image of the video data displayed in the main area M.

[0066] The image DM is drawn in the form of, for example, a marker, a pen, a stamp, etc. The drawing may be drawn by the user's touch, or may be drawn by operating a trackball, for example.

[0067] The drawing data representing the image DM drawn by the user is shared between the information processing devices 10 that display the same video data in the main area M. This makes it possible to visually share information such as the points where to cast nets between ships.

[0068] 9 and 10 are flow diagrams showing an example of a procedure for drawing by a user. The information processing device 10 executes the information processing shown in the figures according to a program, thereby further functioning as a drawing generation unit 26. Steps that overlap with the above procedure example are given the same numbers and detailed explanations are omitted.

[0069] In the description of this example, the information processing device 10 that provides the video data is referred to as a “first information processing device,” and the information processing device 10 that receives the video data is referred to as a “second information processing device.” The information processing device 10 of each ship can be either the first information processing device or the second information processing device.

[0070] As shown in FIG. 9, first, the first information processing device transmits video data to the second information processing device (S15), and the first and second information processing devices display the video data in the main area (S31, S24: processing as the display control unit 24).

[0071] When a drawing is performed in the main area by a user's operation (S32: YES), the first information processing device generates drawing data and transmits it to the second information processing device (S33, S34: processing as the drawing generation unit 26).

[0072] When the second information processing device receives drawing data from the first information processing device, if the video data to be displayed in the main area is common (S41: YES), the second information processing device displays the drawing data together with the video data in the main area (S42: processing as the display control unit 24).

[0073] As shown in FIG. 10, next, when a drawing is performed in the main area by a user operation (S43: YES), the second information processing device generates drawing data and transmits it to the first information processing device (S44, S45: processing as the drawing generation unit 26).

[0074] When the first information processing device receives drawing data from the second information processing device, if the video data to be displayed in the main area is common (S35: YES), the first information processing device displays the drawing data together with the video data in the main area (S36: processing as the display control unit 24).

[0075] Further, a process in the case where a third information processing device different from the second information processing device transmits a video request to the first information processing device (S51) will be described.

[0076] When the first information processing device receives the video request from the third information processing device (S37: YES), it transmits the video data and previous drawing data to the third information processing device (S38: processing as the transmission processing unit 23 and drawing generation unit 26).

[0077] When the third information processing device receives the video data and the previous drawing data from the first information processing device, it displays the previous drawing data together with the video data in the main area (S52: processing as the display control unit 24).

[0078] Here, the previous drawing data refers to drawing data that was generated and shared by the first and second information processing devices before the third information processing device transmits the video request.

[0079] In this way, by transmitting previous drawing data to the third information processing device that subsequently transmitted a video request, it is possible to quickly share the intentions previously expressed in drawings by the users of the first and second information processing devices.

[0080] [Change own and other ship settings] The following describes the process of changing the settings of the own ship and other ships in the information processing method according to the embodiment, which is implemented in the information processing device 10.

[0081] 11 is a diagram for explaining how to change the settings for the own ship and other ships. The setting screen 40 is provided with an own ship display field 41 that shows the source and display of the own ship, and a other ship display field 42 that shows the source and display of the other ships. Using the setting screen 40, it is possible to change the video data displayed in the main area for not only the own ship but also other ships.

[0082] Each of the own ship display field 41 and the other ship display field 42 is provided with a source selection button 43 for receiving a source selection, and a selection display frame 44 showing the source selected for display in the main area. The source selection button 43 and the selection display frame 44 display thumbnails representing video data.

[0083] A check box 45 for switching whether or not to apply the source change is provided in each of the selection display frames 44. Furthermore, an all check box 46 for switching all the check boxes 45 at once is provided above the selection display frames 44.

[0084] As shown in the example, when the check boxes 45 in the selection display frames 44 for both the own ship and the other ship are checked and the source selection button 43 for the other ship's source is selected, video data from the selected other ship's source is displayed in the main areas of both the own ship and the other ship.

[0085] 12 and 13 are flow diagrams showing an example of a procedure for changing the settings of the own ship and other ships. The information processing device 10 executes the information processing shown in the figures according to a program, thereby further functioning as a display request unit 27. Steps that overlap with the above example of the procedure are given the same numbers and detailed explanations are omitted.

[0086] In the description of this example, the information processing device 10 that changes the settings is referred to as a “first information processing device,” and the other information processing device 10 is referred to as a “second information processing device.” The information processing device 10 of each ship can be either the first information processing device or the second information processing device.

[0087] As shown in FIG. 12, first, the first information processing device displays the setting screen 40 (see FIG. 11) (S61).

[0088] Next, when the own ship's source is selected for display on the setting screen 40 (S62: YES), the first information processing device displays the video data of the own ship's source in the main area of ​​the own ship's screen (S63).

[0089] A case where the own ship's source is selected for displaying the own ship is a case where the check box 45 in the own ship's selection display frame 44 on the setting screen 40 shown in Figure 11 is checked and the source selection button 43 for the own ship's source is selected.

[0090] Next, if the source of the own ship is selected to display other ships on the setting screen 40 (S64: YES), the first information processing device transmits video data of the source of the own ship and a request to display it to the second information processing device (S63: processing as the display request unit 27).

[0091] A case where the own ship's source is selected to display other ships is a case where the check box 45 in the other ship selection display frame 44 on the setting screen 40 shown in Figure 11 is checked and the source selection button 43 for the own ship's source is selected.

[0092] The display request is a request for displaying designated video data in the main area of ​​the request destination information processing device.

[0093] When the second information processing device receives a display request from the first information processing device (S71: YES), it displays the video data specified by the display request, here the video data received from the first information processing device, in the main area (S72).

[0094] As shown in FIG. 13, next, when a source of another ship is selected to display the own ship on the setting screen 40 (S66: YES), the first information processing device sends a video request to the second information processing device to request video data of the source of the other ship (S67).

[0095] A case where a source of another ship is selected for displaying the own ship is a case where the source selection button 43 for the source of another ship is selected while the check box 45 in the selection display frame 44 for the own ship is checked on the setting screen 40 shown in Figure 11.

[0096] When the second information processing device receives the video request from the first information processing device (S73: YES), the second information processing device transmits video data to the first information processing device (S74).

[0097] When the first information processing device receives the video data from the second information processing device, the first information processing device displays the received video data in the main area (S68).

[0098] Next, when the source of another ship is selected to display another ship on the setting screen 40 (S69: YES), the first information processing device sends a display request to the second information processing device to request the display of video data of the source of the other ship (S70: processing as the display request unit 27).

[0099] A case where the other ship source is selected for displaying other ships is a case where the source selection button 43 for the other ship source is selected while the check box 45 in the other ship selection display frame 44 on the setting screen 40 shown in Figure 11 is checked.

[0100] When the second information processing device receives a display request from the first information processing device (S75: YES), it displays the video data specified by the display request, in this case the video data that the second information processing device acquires from the source, in the main area (S76).

[0101] By using the setting screen 40 described above, it is possible to change not only the video data displayed in the main area of ​​one's own ship, but also the video data displayed in the main area of ​​other ships.

[0102] When the system is composed of three or more information processing devices mounted on three or more ships, for example, it is possible to specify video data displayed in the main area of ​​the second information processing device by an operation on the first information processing device as a source of the third information processing device. In this case, a display request is transmitted from the first information processing device to the second information processing device, and a video request for the second information processing device is transmitted from the first or second information processing device to the third information processing device.

[0103] Furthermore, while FIG. 11 shows only one source each for the own ship and other ships, if multiple video generating units 14 are connected, multiple sources will be displayed in a list for selection.

[0104] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made by those skilled in the art. [Explanation of symbols]
