  The communication unit 14 controls communication with the mobile terminal 3 and the server 4 through the network 2 under the control of the control unit 10.

  The ROM 15 stores programs and data for controlling basic functions (such as voice calls) preinstalled in the mobile phone 1.

  The RAM 16 stores programs and various data downloaded by the communication unit 14, or programs and data read from the removable memory device 18 through the memory device attaching / detaching unit 17. In this embodiment, route CG data 16b, event data 16c, and BGM data 16d to be reproduced and output by the viewing program 16a are stored in addition to the viewing program 16a that plays back and outputs the content downloaded from the server 4. Further, additional CG data 16e, additional event data 16f, additional BGM data 16g, etc. downloaded to update the route CG data 16b, event data 16c, and BGM data 16d are stored. The viewing program 16a is executed by the control unit 10, thereby realizing the functions of the playback unit 30, the download unit 31, and the event execution unit 32 (details will be described later).

The memory device attaching / detaching unit 17 is a unit for attaching / detaching the removable memory device 18, and mediates reading / writing of data with respect to the removable memory device 18 by the control unit 10.
The GPS unit 19 acquires position data, time data, and the like using a GPS (Global Positioning System).

The reproduction unit 30 realized by the control unit 10 includes a CG reproduction unit 30a, a telop reproduction unit 30b, and an audio reproduction unit 30c.
The CG reproduction unit 30a reproduces and outputs content data downloaded from the server 4, that is, the viewing program 16a, route CG data 16b, and event data 16c stored in the RAM 16, and includes a CG reproduction unit 30a, a telop reproduction unit 30b, An audio playback unit 30c is included.

  The CG reproduction unit 30a reproduces and outputs a video based on the CG technology based on the route CG data 16b. The CG playback unit 30a can change the video based on the CG data in accordance with the situation such as the time of day, the time, and the change in the line of sight. In the CG technology, once a model (CG data) is assembled (modeling), it is possible to easily change the expression and viewpoint in the video. The CG playback unit 30a creates a video corresponding to the situation based on the CG data (shape data) (rendering).

  The telop reproduction unit 30b adds a telop indicating that an event can be executed in the video reproduced and output by the CG reproduction unit 30a according to the event point data embedded in the route CG data 16b.

  The sound reproducing unit 30c reproduces sound at the timing of event point data (BGM point) embedded in the route CG data 16b based on the BGM data 16d. By reproducing the audio at a timing corresponding to the BGM point incorporated in the route CG data 16b, it is possible to output audio (BGM) that matches the displayed video.

FIG. 2A is a diagram illustrating an example of a data format of the route CG data 16 b downloaded through the communication unit 14.
In the route CG data 16b, CG data (modeled shape data) defining a video output by the CG reproducing unit 30a is set in time series. As shown in FIG. 2A, event point data (event points, BGM points) is embedded in the route CG data 16b.

  Event points 1, 2,... Indicate the timing for displaying the telop together with the video. For example, in the telop, contents corresponding to each are displayed in accordance with the timing at which buildings (stores, public facilities, tourist facilities, etc.) and landscapes (sea, mountains, islands, rivers, etc.) are displayed in the video. . The telop indicates that the event can be executed, and a predetermined function set for the corresponding event point is executed by performing a predetermined input operation during the telop display. In the present embodiment, for an input operation (function execution instruction) performed during telop display, for example, a telephone function (phone to function) by the telephone function unit 32a and a web access function (Web to function) by the web function unit 32b The application unit 32c can execute an application function (for example, an application for giving a quiz).

  The event data 16c can be partially changed by the additional CG data 16e downloaded from the server 4. For example, a new building can be displayed in the video, or an event point or BGM point can be added to enable execution of a new event.

  BGM points 1, 2,... Indicate the timing for displaying audio (music) to be output together with the video. For example, when a characteristic landscape is displayed in the video, a BGM adapted to the landscape can be output at that timing.

FIG. 2B is a diagram showing BGM data 16d associated with the route CG data 16b.
The BGM data 16d includes music data (BZM1, 2,...) Corresponding to the BGM points 1, 2,... Embedded in the route CG data 16b. The BGM data 16d may be downloaded together with the appreciation program 16a and the route CG data 16b, use music data downloaded from the server 4 that distributes music content, and further stored in the removable memory device 18 in the PC 5. It is also possible to read out and use the recorded music data through the memory device attaching / detaching unit 17. Further, the additional BGM data 16g downloaded from the server 4 can be used.

3A and 3B are diagrams showing an example of the data configuration of the event data 16c.
The event data 16c can include event data 1, 2,... Having a plurality of different purposes. The event data 1, 2,... Can be individually downloaded from the server 4. For example, event data for sightseeing spots displayed in the video, event data for guiding the scenery, and event data corresponding to the line-of-sight direction (forward, left, etc.) can be prepared.

  In the event data, data corresponding to the function (phone, web access, application) executed at the point is set in association with the event point at which the event is executed. For example, in order to execute the telephone function at the event point 1 where the store is displayed in the video, the phone number of the store is set in the event data. Similarly, in order to execute the Web access function, a URL (uniform resource locator) address indicating an access destination is set. For the application function, for example, an application start command for setting a quiz about a tourist facility (such as a shrine or temple) displayed in the video is set. Of course, the application may be another application other than the quiz questions.

Next, the operation of the mobile phone 1 (viewing program 16a) in the present embodiment will be described with reference to the flowcharts shown in FIGS.
First, the overall flow of the viewing process by the viewing program 16a will be described with reference to the flowchart shown in FIG. The appreciation process in the present embodiment will be described by taking as an example a case of reproducing content for viewing the scenery around the railway line.

  The control unit 10 accesses the server 4 via the network 2 in response to a user operation on the input unit 12, downloads the viewing program 16 a and stores it in the RAM 16. The control unit 10 enables the playback unit 30, the download unit 31, and the event execution unit 32 to be executed by executing the viewing program 16a.

  When selection of a route to be viewed is input by a user operation (step A1), the control unit 10 determines whether route CG data 16b corresponding to the selected route has already been downloaded. Here, if the corresponding route CG data 16b has not been downloaded (step A2, No), the download unit 31 accesses the server 4 through the communication unit 14 and downloads the route CG data 16b (step A3).

  On the other hand, although the corresponding route CG data 16b is downloaded (step A2, Yes), for example, when viewing with the latest data (step A4, No), downloading of additional data is executed. Whether to use the existing route CG data 16b (initial data) or to download additional data may be selected by the user, or the server 4 determines whether the existing route CG data 16b is the latest data. Additional data may be downloaded unconditionally when inquiring and not up-to-date.

  When downloading the BGM data corresponding to the route CG data 16b (step A5, Yes), the download unit 31 accesses the server 4 to download the additional BGM data 16g (step A7). If no BGM data is added (step A5, No), the existing initial data (BGM data 16d) is used (step A6).

  Moreover, when downloading the additional data of the route CG data 16b and the event data 16c (step A8, Yes), the download unit 31 accesses the server 4 to add the additional CG data 16e and the corresponding data. Event data 16f is downloaded (step A10). If the route CG data 16b is not changed (step A8, No), the existing initial data (route CG data 16b, event data 16c) is used (step A9).

  Next, the reproducing unit 30 executes sightseeing play mode processing for reproducing and outputting the content downloaded from the server 4 (step A11). The details of the sightseeing play mode process will be described later (FIG. 5).

  The control unit 10 repeatedly executes the sightseeing play mode process until the end of the viewing process is instructed (step A12, Yes).

Next, details of the sightseeing play mode process will be described with reference to the flowchart shown in FIG.
The reproducing unit 30 reads data to be reproduced and output from the route CG data 16b (or additional CG data 16e) stored in the RAM 16 (step B1). The reproducing unit 30 determines whether the read data is data indicating an event point or a BGM point (steps B2 and B3).

  If the read data is not an event point or a BGM point (step B2 / B3, No), the CG playback unit 30a creates a video by CG based on the CG data (modeled shape data), and displays the display unit. 11 (step B4). Hereinafter, a CG image based on the sequentially read CG data is displayed. The reproduction unit 30 continues the reproduction process until reproduction output for all the CG data of the route CG data 16b is finished (step B8, Yes).

  On the other hand, when it is determined that it is an event point (step B2, Yes), the telop playback unit 30b adds a telop corresponding to the event point to the video displayed by the CG playback unit 30a (step B5). The telop playback unit 30b continuously displays the telop for a predetermined time (for example, while the object is displayed in the video).

  FIG. 7A shows a display example in which the telop “Enoshima” is displayed in the video. FIG. 7A shows an example of a video image of the railway “Enoshima Electric Railway”. Enoshima appears in the video image. In the route CG data 16b, an event point (for example, event point 4) for displaying the telop “Enoshima” is embedded in accordance with the timing at which the video of Enoshima is displayed.

  As shown in FIG. 7A, when an execution instruction for a predetermined function is operated while a telop is displayed, a function (event) related to the telop can be executed (event execution processing). (Step B12)). Details will be described later.

  If it is determined that the read data is a BGM point (step B3, Yes), the audio reproduction unit 30c performs a BGM reproduction process for reproducing and outputting music based on the BGM data corresponding to the BGM point. Execute (Step B6). The audio reproducing unit 30c continuously reproduces and outputs the music until the reproduction of the music is completed or until a BGM point instructing reproduction of another BGM is determined.

  If there is a button operation by the user during playback and output of the video (step B7, Yes), the control unit 10 determines that the direction of the line of sight is changed by operating the cursor button (step B9, Yes). The line-of-sight direction of the video reproduced by the reproduction unit 30a is changed.

  When the video based on the CG data is generated, the CG playback unit 30a displays the video with the line-of-sight direction changed in the direction specified by the user (steps B10 and B4). Since the CG reproducing unit 30a generates a video based on the CG data, the video can be easily changed in response to a change instruction of the line-of-sight direction.

  FIG. 7B shows a video example when an instruction to change the line-of-sight direction to the left at the timing when the video shown in FIG. 7A is displayed. In FIG. 7A, the line direction (front) is the line-of-sight direction, but in FIG. 7B, the line-of-sight direction is changed to the left front.

  In addition, the telop added to the video shown in FIG. 7B is changed to “Nanarigahama Beach”. For example, it is assumed that the event data 1 shown in FIG. 3A is for the route direction, and the event data 2 shown in FIG. 3B is for the left front direction.

  The telop reproduction unit 30b displays a telop corresponding to the line-of-sight direction as shown in FIG. 7B when the line-of-sight direction is changed even at the same event point (for example, event point 4). Accordingly, when an execution instruction for a predetermined function is operated while the left front telop is displayed, a function (event) based on the left front event data 2 can be executed.

  When the button operation by the user while the telop is displayed is an event execution instruction (step B7 / B11, Yes), the event execution unit 32 performs an event execution process according to the input operation (step B12). .

Next, event execution processing will be described with reference to the flowchart shown in FIG.
For example, when there is a function execution instruction (for example, an operation with a selection execution button) while the telop is displayed, the event execution unit 32 responds to the data set in association with the corresponding event point. Execute the function.

  For example, if the telephone number data is set, it is determined that the telephone function is to be executed (step C1, Yes). The telephone function unit 32a executes a calling process using the telephone number set in the event data 16c as the connection destination (step C2). The event execution unit 32 displays a message for notifying the user that the transmission is being performed on the display unit 11 (step C3). For example, when a telop is added to a famous store in the video, it is possible to call the store by simply pressing the selection execution button while the telop is displayed.

  If the URL address is set in the event data 16c, it is determined that the Web access function is executed (step C4, Yes). The web function unit 32b executes a web access process using the URL address set in the event data 16c as an access destination (step C5). The event execution unit 32 causes the display unit 11 to display the web page accessed by web access (step C6). For example, if a telop is added to a landscape that appears in the video, you can access a Web page that contains data related to the landscape simply by pressing the execute button while the telop is displayed. Can be displayed.

  If an application activation command is set in the event data 16c, it is determined that the application is to be executed (step C7, Yes). The application unit 32c executes an activation command, and executes an application (program) stored in the RAM 16 (or ROM 15, removable memory device 18) (step C8). The event execution unit 32 causes the display unit 11 to display an application execution screen (step C9). For example, if a telop has been added to a shrine or temple that appears in the video, simply press the select execution button while the telop is displayed, and the application that asks questions related to that shrine or temple will be executed. be able to.

  When the execution of each function is completed (step C10, Yes), the event execution unit 32 ends the event execution process.

  In the above description, only the selection execution button is operated while the telop is displayed. In this case, operability can be improved because the operation method is unified without being aware of what data is set in the event data (regardless of the function (event) to be executed). . On the other hand, the executable function is one for one telop.

  On the other hand, a button provided in the input unit 12 is assigned to each function so that a plurality of functions (events) can be executed for one telop, and activated depending on which button is operated. A function may be selected. For example, a telephone number, a URL address, and an application activation command are all set for one event point, and a telephone set in event data when a button for instructing execution of a telephone function is operated. Try to call the number. Thereby, a function (event) required by the user can be arbitrarily selected and executed.

  In addition, although it has been described that one telop is displayed in the video, if multiple telops are displayed, select a telop with a predetermined button to instruct the execution of the event It can be so.

  In the above description, the video generated based on the CG data is changed according to the instruction to change the line-of-sight direction. However, the video may be generated according to a change in other situations. . For example, the video based on the CG data is generated by the CG reproduction unit 30a according to the date and time that is counted by the control unit 10. As a result, in the same manner as when the actual landscape changes due to a change in time or due to a difference in time, an image corresponding to a difference in time or time can be displayed for the video reproduced and output by the CG playback unit 30a. . By changing the video according to the difference in the situation, it is possible to enjoy the situation in which the video reproduced by the mobile phone 1 corresponds to the actual landscape.

  In the above description. The viewing route is selected and the route CG data 16b is downloaded (FIG. 4, steps A1 to A3), but content data including the route CG data 16b corresponding to the current position detected by the GPS unit 19 is received from the server 4. You can download it for viewing. For example, when it is determined from the position data detected by the GPS unit 19 that the user is on the route of “Enoshima Electric Railway”, the server 4 is accessed through the communication unit 14 to download the content about “Enoshima Electric Railway”. In addition, instead of downloading the entire content of “Enoshima Electric Railway”, content targeted for a limited range may be sequentially downloaded according to position data that changes with movement.

  In the above description, the sight line direction when displaying the CG image is an example of the front and the left front. However, other sight line directions may be used as a matter of course. For example, it is possible to arbitrarily specify a horizontal direction, a downward direction, an upward direction, a backward direction, and the like. Since the reproduction unit 30 (CG reproduction unit 30a) reproduces and outputs the video by CG, the video can be displayed according to the designated viewing direction.

  In addition, the reproduction of video and audio by the reproduction unit 30 can be executed by returning the reproduction position. For this reason, even if the video (telop display) for which the event was to be executed is ended, the playback position can be returned and the same video and audio can be reproduced and output again to execute the desired event.

  In addition, although an example in which the mobile phone 1 is used to appreciate the railway line scenery has been described, the following usage method is also possible.

  (1) Sightseeing that can be enjoyed on a train driving game that simulates driving operations while displaying landscape images viewed from the train driver's seat using CG data modeled on live-action images.・ Promotional software. Similarly, a car driving game that simulates driving operations while displaying images from the driver's seat of the car.

  (2) Guidance software that displays terrain in 3D (three-dimensional) images instead of two-dimensional maps.

  (3) Environmental software that can freely replace music to be played back and output together with video and customize it according to user preferences.

  (4) Advertising software that distributes image songs etc. tie-ups with companies and local governments.

  (5) Educational software that expresses past cityscapes and future cityscapes with CG images, allowing you to experience the present, past, and future.

  (6) Software that can display various questions at the same time as the scenery of the cityscape, etc., and allows the user to perform various learning by returning a reaction.

  In this way, the mobile phone 1 (viewing program 16a) in the present embodiment displays an image based on the downloaded route CG data 16b, and an image according to the BGM point embedded in the route CG data 16b. You can output music that suits your needs. In addition, event points are embedded in the route CG data 16b, and a telop corresponding to the video can be displayed according to the event points. Then, by performing a predetermined input operation while the telop is displayed, a function (event) using a communication function (communication unit 14) provided in the mobile phone 1, that is, a telephone function or a Web function is executed. be able to. It is also possible to execute an arbitrary application for a target in a video to which a telop is added.
