  As shown in FIG. 1, the display control device S according to the embodiment includes an acquisition unit 2 and a control unit 2A.

  In this configuration, the acquisition unit 2 acquires feature image information corresponding to a feature image obtained by front-viewing a feature existing on the side of the moving path on which the moving object moves.

  Then, the control unit 2A uses the feature image information acquired by the acquisition unit 2 to simultaneously display the feature images for the features present on both sides of the moving path.

  As described above, according to the operation of the display control device S according to the embodiment, the feature image obtained by viewing the feature existing on the side of the moving path from the front is displayed on the feature object existing on both sides of the moving path. Are displayed at the same time, so that even if there is a feature that cannot be visually recognized because it is obstructed by a shield, for example, it is possible to confirm them on both sides of the moving path at the same time.

  Next, a specific example corresponding to the above-described embodiment will be described with reference to FIGS. The embodiment described below is an embodiment in which the present application is applied to display control of an image of a peripheral facility or the like using a navigation device mounted on a vehicle.

  FIG. 2 is a block diagram illustrating a schematic configuration of the navigation according to the embodiment, and FIG. 3 is a flowchart illustrating a display control process according to the embodiment. FIG. 4 is a diagram illustrating an example of a defeated facility according to the embodiment, and FIG. 5 is a diagram illustrating an example of a look-up facility according to the embodiment. At this time, in FIG. 2, the same component numbers as those in the display control device S are used for the components of the example corresponding to the components in the display control device S according to the embodiment illustrated in FIG. 1. ing.

  As shown in FIG. 2, the navigation device NV according to the embodiment is a navigation device mounted on a vehicle for a family, for example, having a wide roof. The navigation device NV includes an interface 1, a processing unit 2 including a CPU, a random access memory (RAM), a read only memory (ROM), and the like. A projection unit 3 for projecting and displaying a tilted facility display according to the example, an operation unit 4 including a touch sensor or a remote controller, and a tertiary according to the embodiment including a HDD (Hard Disc Drive) or an SSD (Solid State Drive) or the like. The storage unit 5 stores original data and the like, and a sensor unit 6 including a GPS (Global Positioning System) sensor or an independent sensor. At this time, the processing unit 2 corresponds to an example of the acquisition unit 2 according to the embodiment, an example of the control unit 2A, and an example of the “moving path information acquisition unit” according to the present application, and the processing unit 2 and the sensor unit 6 correspond to the present application. This corresponds to an example of such “distance information acquisition means”.

  In this configuration, under the control of the processing unit 2, the interface 1 controls wireless data transmission and reception with an external network such as the Internet. The sensor unit 6 detects the current position of the navigation device NV (in other words, the current position of the vehicle equipped with the navigation device NV) using the GPS sensor or the like under the control of the processing unit 2, The current position data indicating the current position is generated and output to the processing unit 2. On the other hand, when an operation to be executed by the navigation device NV is executed on the operation unit 4, the operation unit 4 generates an operation signal corresponding to the operation and outputs the operation signal to the processing unit 2. On the other hand, the storage unit 5 executes the guidance processing as the navigation device NV, starting with the three-dimensional data D of the peripheral facility and the like used for the display of the defeated facility according to the embodiment described below and the look-up facility according to the embodiment. For example, map data, a navigation program, a display control program for executing a display control process according to the embodiment, and the like are stored in a nonvolatile manner. At this time, in the three-dimensional data D, for example, position data indicating the position of the peripheral facility or the like in latitude / longitude, height data indicating the height of the peripheral facility or the like, and the peripheral facility or the like is looked down from above. In this case, house shape data indicating the house shape in the case of the above and three-dimensional data for projecting and displaying the surrounding facilities and the like three-dimensionally (in other words, three-dimensionally) are included. In addition to these, the storage unit 5 stores height threshold data indicating the threshold of the actual height of the peripheral facility or the like referred to when switching between the defeated facility display and the look-up facility display according to the embodiment as described later. Remember. The height threshold data is, for example, height threshold data set in advance for each region on the map, and an example to be described later when the actual height of a peripheral facility or the like is equal to or larger than the threshold of the height. Is displayed, and when the actual height of the peripheral facility or the like is less than the threshold value of the height, a defeated facility display according to the embodiment described later is executed.

  As the height threshold data, one height threshold data may be stored regardless of the area. Further, for example, the value of the height threshold data may be changed according to the attribute of a place such as an urban area, a residential area, and a station area. Further, for example, the value of the height threshold data is preset according to the number of peripheral facilities existing within a preset range from the current position of the navigation device NV (in other words, the vehicle in which the navigation device NV is mounted). May be.

  Accordingly, the processing unit 2 executes the guidance processing as the navigation device NV using the map data and the navigation program, and uses the display control program for performing the defeated facility display and the look-up facility display. Is performed. Then, under the control of the processing unit 2, the projection unit 3 projects and displays an image as a result of the display control process according to the embodiment together with, for example, an image for a guidance process on the vehicle interior ceiling.

  Here, the "defeated facility display" according to the above-described embodiment is a facility or a natural object (that is, the above-described peripheral facility or the like, which is present on both sides of a road on which a vehicle equipped with the navigation device NV moves). The facility and natural objects are collectively referred to as “peripheral facilities, etc.”), and the image obtained when the front is viewed horizontally (that is, when viewed horizontally) is simultaneously obtained for the peripheral facilities and the like present on both sides of the road. This means projecting and displaying on the ceiling inside the vehicle. There are two modes of the defeated facility display according to this embodiment, and each mode will be described in detail later.

  On the other hand, the “looking-up facility display” according to the above-described embodiment refers to a facility located on both sides of a road on which a vehicle equipped with the navigation device NV moves, which is located above the current position of the vehicle on the road. (I.e., the image obtained by looking up in the vertical direction) is simultaneously projected and displayed on the ceiling in the vehicle for the surrounding facilities and the like present on both sides of the road. The look-up facility display according to this embodiment will also be described later in detail.

  Next, a display control process according to the embodiment, which is mainly performed by the processing unit 2 in the navigation device NV having the configuration described with reference to FIG. 2, will be described more specifically with reference to FIGS. I do.

  As shown in a flowchart corresponding to the whole in FIG. 3A, the display control process according to the embodiment is started, for example, at a timing when a power switch (ACC (Accessory) switch of the vehicle) of the navigation device NV is turned on. Is done. Then, when the display control process is started, the processing unit 2 of the navigation device NV monitors, for example, whether the operation unit 4 instructs the projection unit 3 to project an image of a peripheral facility or the like onto the vehicle interior ceiling. (Step S1). In the monitoring of step S1, when the image projection to the ceiling in the vehicle is not instructed (step S1: NO), the processing unit 2 proceeds to step S9 described below.

  On the other hand, in the monitoring of step S1, when the image projection on the vehicle ceiling is instructed (step S1: YES), the processing unit 2 acquires the current position data indicating the current position of the vehicle from the sensor unit 6 ( Step S2). Thereafter, the processing unit 2 acquires, from the storage unit 5, height data indicating the height of a peripheral facility or the like around the current position indicated by the current position data acquired in step S2 (step S3). At this time, the peripheral facility or the like that acquires the height data acquires, for example, the height data of the peripheral facility or the like that is within the field of view viewed from the current position of the vehicle. Next, the processing unit 2 acquires the height threshold data corresponding to the area including the current position indicated by the current position data acquired in Step S2 from the storage unit 5 (Step S4). After that, the processing unit 2 outputs the three-dimensional data D for projecting the peripheral facilities and the like for which the height data has been acquired in step S3 to the ceiling in the vehicle as the defeated facility display according to the embodiment or the look-up facility display according to the embodiment. Is obtained from the storage unit 5 (step S5).

  Next, the processing unit 2 determines whether or not, for example, the maximum value of the height of the peripheral facility or the like acquired in Step S3 is equal to or greater than the height threshold data acquired in Step S3 (Step S6). In the determination in step S6, when the maximum value of the height of the peripheral facility or the like acquired in step S3 is less than the height threshold data acquired in step S3 (step S6: NO), the processing unit 2 stores The projection unit 3 and the like are controlled so as to execute the defeated facility display according to the embodiment using the three-dimensional data D stored in Step 5 (Step S7), and thereafter, the process proceeds to Step S9 described later. Step S7 will be described later in detail.

  On the other hand, in the determination in step S6, when the maximum value of the height of the peripheral facility or the like acquired in step S3 is equal to or greater than the height threshold data acquired in step S3 (step S6: YES), the processing unit 2 stores The projection unit 3 and the like are controlled so as to execute the look-up facility display according to the embodiment using the three-dimensional data D stored in the unit 5 (step S8). This step S8 will also be described later in detail.

  In the determination in step S6, the processing unit 2 may compare the average value of the heights of the peripheral facilities and the like acquired in step S3 with the height threshold data acquired in step S3. In addition, in the determination in step S6, the processing unit 2 may compare with the minimum value of the height of the peripheral facility or the like acquired in step S3, in addition to comparing with the maximum value or the average value. Further, the processing unit 2 may switch between step S7 and step S8 based on, for example, whether or not half or more of the peripheral facilities and the like are higher than the height threshold data as the determination in step S6. . In these cases, the processing unit 2 causes the look-up facility display according to the embodiment to be performed when the average value or the like of the heights compared with the height threshold data is equal to or greater than the height threshold data, and the average value or the like is displayed. When the height is less than the height threshold data, it is preferable to display the defeated facility according to the embodiment.

  Furthermore, the processing unit 2 may make the determination using only the height of the peripheral facility or the like existing on one side of the road on which the vehicle equipped with the navigation device NV moves in the determination of step S6, The determination may be made using the heights of peripheral facilities and the like present on both sides thereof. In this case, at the timing of performing the determination in step S6, the processing unit 2 performs the determination using only the height of the peripheral facility or the like existing on one side of the road or determines the height of the peripheral facility or the like existing on both sides of the road. May be used to make the determination, or when acquiring the height data in step S3, acquire only the height data of peripheral facilities or the like present on one side of the road. Alternatively, the user may select whether to acquire height data of peripheral facilities or the like existing on both sides thereof.

  After that, the processing unit 2 determines whether to terminate the display control process according to the embodiment, for example, because the power switch of the navigation device NV is turned off (Step S9). When the display control process is terminated in the determination of step S9 (step S9: YES), the processing unit 2 terminates the display control process as it is. On the other hand, if it is determined in step S9 that the display control process is to be continued (step S9: NO), the processing unit 2 returns to step S1 and repeats the above-described series of processes.

  Next, step S7 will be described in detail with reference to FIGS. When performing the tilted facility display as step S7, first, the processing unit 2 sets the top of the peripheral facility or the like inside the projection area when projecting and displaying an image obtained by viewing the peripheral facility or the like in a horizontal front view. An operation signal for instructing whether to display or display outside is acquired via the operation unit 4 (step S70). Here, the top of the peripheral facility or the like is the top of the roof when the peripheral facility or the like is, for example, a house, and the top floor or the tip of the roof when the peripheral facility or the like is, for example, a building or a tower. Department. If the operation signal acquired in step S70 indicates that the display is to be performed with the top of the peripheral facility or the like inside (step S70: inside), the processing unit 2 sets the top to the inside and displays the peripheral facility or the like. The projection unit 3 is controlled so that an image corresponding to the front is projected on the ceiling in the vehicle (step S72). After that, the processing unit 2 proceeds to step S9 shown in FIG. The display of the image by the projection in step S72 is hereinafter referred to as "inside-down facility display".

  Here, the inward tilt display in step S72 will be described more specifically with reference to FIGS. 4 (a) and 4 (b). 4B, FIG. 4C, and FIG. 5B, which will be described below, the upper part in the figure is the traveling direction (forward) of the vehicle on which the navigation device NV is mounted.

  First, as exemplified in a map in FIG. 4A, the current position of the vehicle equipped with the navigation device NV is the position indicated by the current position mark PM, and the surrounding facilities such as peripheral facilities 10 to 10 It is assumed that a facility or the like 17 is built (see steps S2 and S3 in FIG. 3A). Then, as the inward-facing facility display projected on the vehicle interior ceiling at the current position illustrated in FIG. 4A, as illustrated in FIG. 4B, FIG. 4B in the projection area AR of the vehicle interior ceiling is used. 10) Images 10G to 17G corresponding to the fronts of the peripheral facilities 10 to 17 are displayed on the middle left and right sides, respectively. In these images 10G to 17G, the respective tops are displayed so as to face the inside of the projection area AR. The processing unit 2 also displays images 10G to 13G corresponding to the fronts of the peripheral facilities 10 to 13 on the left side in the traveling direction of the road R illustrated in FIG. Are displayed on the left side of the vehicle in the order in which the peripheral facilities 10 to 13 are built in the moving direction of the vehicle. Further, for the peripheral facilities 14 to 17 located on the right side in the traveling direction of the road R illustrated in FIG. 4A, the processing unit 2 outputs images 14G to 17G corresponding to the respective fronts to the projection area AR. On the right side of the figure, the moving directions of the vehicle are displayed in the order in which the peripheral facilities 14 to 17 are built. In the case illustrated in FIG. 4B, the left edge of the projection area AR in FIG. 4B corresponds to the ground on the right side in the traveling direction of the road R, while the projection area AR in FIG. The middle right edge corresponds to the ground on the left side in the traveling direction of the road R. By projecting the images 10G to 17G into the projection area AR in the mode illustrated in FIG. 4B, the traveling direction (forward) of the vehicle on which the navigation device NV is mounted and the projected inside-down facility display are displayed. The traveling direction coincides with the traveling direction, and as a result, the direction in which the actual peripheral facility 10 or the like is viewed from the vehicle and the direction in the field of view of the viewer such as the image 10G or the like projected corresponding thereto. And the arrangement in the projection area AR of the image 10G or the like also matches the corresponding peripheral facility 10 or the like. That is, in the case of the inward-facing facility display according to the embodiment, the image 10G or the like is projected as a scene similar to the case where the surrounding facility or the like 10 is looked up from inside the vehicle.

  On the other hand, when the operation signal acquired in step S70 instructs that the top of the peripheral facility or the like is displayed outside (step S70: outside), the processing unit 2 sets the top to the outside and displays the peripheral facility or the like. An image corresponding to the front is projected on the ceiling in the vehicle (step S71). After that, the processing unit 2 proceeds to step S9 shown in FIG. The display of the image by the projection in step S71 is hereinafter referred to as “outside-leaved facility display”.

  Here, the outward tilt display in step S71 will be described more specifically with reference to FIGS. 4A and 4C. As in the case of step S72, the current position of the vehicle on which the navigation device NV is mounted is the position indicated by the current position mark PM illustrated in FIG. It is also assumed that peripheral facilities 17 are built. 4 (b). As an example of the outward-facing facility display projected on the vehicle interior ceiling at the current position illustrated in FIG. 4 (a), as illustrated in FIG. 10) Images 10G to 17G corresponding to the fronts of the respective peripheral facilities 10 to 17 are displayed such that the tops of the peripheral facilities 10 to 17 are directed to the middle left and right outer sides. In addition, a road image RG corresponding to the road R illustrated in FIG. 4A is displayed at the center of the projection area AR in this case, and the base of each of the images 10G to 17G is a road image. It is displayed along the RG and with each apex pointing outside the projection area AR. Further, the processing unit 2 converts the images 10G to 13G corresponding to the fronts of the peripheral facilities 10 to 13 on the left side in the traveling direction of the road R illustrated in FIG. In the area on the left side of the projection area AR, the moving direction of the vehicle is displayed in the order in which the peripheral facilities 10 to 13 are built. Further, for the peripheral facilities 14 to 17 located on the right side in the traveling direction of the road R illustrated in FIG. 4A, the processing unit 2 converts the images 14G to 17G corresponding to the fronts into road images RG. In the area on the right side of the projection area AR, the moving directions of the vehicle are displayed in the order in which the peripheral facilities 14 to 17 are built. By projecting the images 10G to 17G in the projection area AR in the mode illustrated in FIG. 4C, the traveling direction (forward) of the vehicle on which the navigation device NV is mounted and the projected outside tilted facility display are displayed. The traveling direction coincides with the traveling direction, and as a result, the direction in which the actual peripheral facility 10 or the like is viewed from the vehicle and the direction in the field of view of the viewer such as the image 10G or the like projected corresponding thereto. And the arrangement in the projection area AR of the image 10G or the like also matches the corresponding peripheral facility 10 or the like.

  Next, step S8 will be described with reference to FIG. First, as exemplified in a map in FIG. 5A, the current position of the vehicle equipped with the navigation device NV is the position indicated by the current position mark PM, and the surrounding facilities such as peripheral facilities 20 to 20 It is assumed that a facility 23 is built (see steps S2 and S3 in FIG. 3A. The peripheral facility 23 is a tower type facility). As a look-up facility display projected on the vehicle interior ceiling at the current position illustrated in FIG. 5 (a), as illustrated in FIG. 5 (b), a three-dimensional view toward the center of the projection area AR of the vehicle interior ceiling is obtained. The images 20G to 23G corresponding to the peripheral facilities 20 to 23, respectively, are displayed so that the peripheral facilities 20 to 23 rise. In these images 20G to 23G, the tops are stereoscopically displayed such that the tops are directed toward the center of the projection area AR. Further, the processing unit 2 converts the images 20G and 21G corresponding to the peripheral facilities 20 and the peripheral facilities 21 on the right side in the traveling direction of the road R illustrated in FIG. The moving directions of the vehicle are displayed in the order in which the surrounding facilities 20 and the surrounding facilities 21 are built so as to rise from the edge. Further, the processing unit 2, for the peripheral facilities 22 and the peripheral facilities 23 on the left side in the traveling direction of the road R illustrated in FIG. The moving directions of the vehicle are displayed in the order in which the surrounding facilities 22 and the surrounding facilities 23 are built so as to rise from the edge. 5B, the right edge of the projection area AR in FIG. 5B corresponds to the direction of the ground on the left side in the traveling direction of the road R, while the projection area AR in FIG. b) The middle left edge corresponds to the direction of the ground on the right side in the traveling direction of the road R.

  4B, 4C and 5B, for example, images 10G to 17G (see FIGS. 4B and 4C) and images 20G to 20G As shown in FIG. 22G (see FIG. 5B), in addition to the simplified image of the corresponding peripheral facility 10 and the like, an image of the corresponding peripheral facility 10 and the like is stored in the storage unit 5 in advance. Alternatively, the image 10G to the image 17G and the image 20G to the image 22G may be projected and displayed so as to be more realistic by using the actual photographed image.

  In addition, as a look-up facility display according to the embodiment (see FIG. 5), a portion above the upper edge of the window on both sides of the vehicle as viewed from the inside of the vehicle on which the navigation device NV is mounted (that is, the inside of the vehicle) From the position of the eyes, only the images 20G to 23G corresponding to the part that is not actually visible when blocked by the ceiling (roof) of the vehicle may be configured to be projected and displayed on the projection area AR. Here, when projecting and displaying the images 20G to 23G corresponding to portions higher than the preset height in the peripheral facility 10 or the like, for example, the preset height may be fixed, The preset height may be changeable. Further, when the preset height can be changed, for example, the user may freely change the height, or an attribute (for example, an attribute around the current position of the vehicle on which the navigation device NV is mounted) (for example, , An attribute such as a city area or a residential area).

  As described above, according to the display control processing according to the embodiment, images obtained by front-viewing peripheral facilities and the like existing on the side of the road are simultaneously projected and displayed on the peripheral facilities and the like existing on both sides of the road. Therefore, for example, even if there are peripheral facilities or the like that cannot be visually recognized because they are blocked by a shield, they can be simultaneously checked on both sides of the road.

  In addition, since images of each peripheral facility are displayed simultaneously in the order in which they are visually recognized by the movement of the vehicle, the peripheral facilities and the like existing on both sides of the road are displayed, so that the surrounding facilities can be checked while recognizing changes accompanying the movement. can do.

  Further, since the images 10G and the like of the peripheral facilities and the like are displayed while being moved in accordance with the movement of the moving body, it is possible to display the images 10G and the like on both sides with more realistic feeling.

  Furthermore, in the case of the inward-facing facility display (see FIG. 4B), the images 10G and the like of the respective peripheral facilities are displayed such that the tops of the respective peripheral facilities and the like are located inside in the projection area AR. The image 10G or the like can be displayed with an increased sense of realism.

  On the other hand, in the case of the outer-facing facility display (see FIG. 4C), the images 10G and the like of the respective peripheral facilities are displayed together with the road image RG such that the tops of the respective peripheral facilities and the like are located outside in the projection area AR. Therefore, it is possible to display the image 10G or the like with further enhanced realism.

  Further, since the images 10G and the like of the peripheral facilities and the like are displayed on the ceiling in the vehicle, the images 10G and the like can be displayed with an increased sense of reality as the vehicle moves.

  In the above-described embodiment, the display of the defeated facility according to the embodiment and the look-up facility display according to the embodiment are switched based on the relationship between the height of the surrounding facilities and the height threshold data (FIG. ) Refer to steps S6 to S8). In addition to the above, the defeated facility display according to the embodiment is not compared with the height threshold data but based on the attribute of the place such as "city area" or "residential area". It may be configured to perform switching to the look-up facility display according to the embodiment.

  Further, in the above-described embodiment, in the inverted facility display according to the embodiment, it is configured to switch whether the top of the peripheral facility or the like is displayed inside or outside the projection area in the projection area (FIG. 3B). Alternatively, step S70) may be a display mode of one of the preset navigation devices NV (either the display with the top inside or the display outside).

  Further, in the above-described embodiment, when a route to which the vehicle equipped with the navigation device NV is to be moved is set in advance, the vehicle travels along the route instead of the peripheral facilities or the like that can be visually recognized. The above-mentioned defeated facility display or look-up facility display may be performed for a peripheral facility or the like that is sometimes visible. In this case, for example, when the above-mentioned route for turning left at the intersection ahead in the traveling direction is set, the peripheral facility or the like which is visually recognized when the vehicle goes straight through the intersection (if the above-mentioned route is not set, it corresponds to this peripheral facility or the like) Instead of displaying an image of a falling facility or a facility looking up, the surrounding facility or the like that is visually recognized left and right when the intersection is turned left may be displayed. In this case, based on the information on the route, an image of each peripheral facility at the side of the road to be moved is displayed, so that the peripheral facility at the position to be moved can be recognized in advance.

  Furthermore, in the display of the defeated facility according to the embodiment, only the peripheral facilities and the like immediately beside the current position of the vehicle equipped with the navigation device NV (that is, the front side in the traveling direction) are viewed in a horizontal front view. In addition to projecting and displaying using the front image obtained as a result, other peripheral facilities and the like in the front and rear directions of the movement, in addition to the front image, the side of the other peripheral facilities and the like visible from the current position. By displaying the images together, it is also possible to perform a three-dimensional inverted facility display. In this case, the image of the other peripheral facility or the like is obliquely viewed (that is, obliquely viewed). Also in this case, by using the three-dimensional data D according to the embodiment, the three-dimensional inverted facility display can be performed. In this case, for other peripheral facilities etc. other than the peripheral facilities etc. in front of the side in the traveling direction of the road, an image obtained by obliquely viewing the same is displayed simultaneously for the peripheral facilities etc. present on both sides of the road. Therefore, images of the surrounding facilities and the like on both sides can be displayed with a higher sense of reality.

  Further, in the display of the defeated facility according to the embodiment, a peripheral facility or the like nearer the current position of the vehicle equipped with the navigation device NV may be displayed as a relatively large image.
