Can be executed in the navigation processing procedure.

(An example of navigation processing of the navigation device 300)
Next, an example of navigation processing performed by the navigation device 300 according to the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart illustrating an example of the navigation process of the navigation device according to the present embodiment.

  In the flowchart of FIG. 4, the navigation device 300 is in the normal mode in which the route search to the destination is completed and the map information is displayed on the display 312. In the normal mode, the navigation device 300 is in a standby state until an instruction to start mode switching is received (step S401: No loop). When an instruction to start mode switching is received (step S401: Yes), the current position of the vehicle Is identified (step S402). Then, it is determined whether or not the current position is within a predetermined distance from the home (step S403). When it is determined in step S403 that the current position is within a predetermined distance from the home (step S403: Yes), design image information is selected (step S404).

  On the other hand, if it is determined in step S403 that the current position is not within a predetermined distance from the home (step S403: No), it is determined whether or not the current position is an expressway (step S405). If it is determined in step S405 that the current position is an expressway (step S405: Yes), the process proceeds to step S404. On the other hand, if it is determined in step S405 that the current position is not an expressway (step S405: No), it is determined whether or not there is a guidance “for a while” (step S406). In step S406, if there is a guidance “for a while” (step S406: Yes), the process proceeds to step S404.

  After design image information is selected (step S404), the traveling speed of the vehicle is detected based on the output value from the vehicle speed sensor (step S407). Then, the design image information is changed according to the detected traveling speed of the vehicle (step S408). Then, the display 312 displays a design mode that changes according to the traveling speed (step S409). The displayed image is an image that is completed when the destination is reached.

  Then, it is determined whether there is guidance at the guidance position (step S410). The guidance position is, for example, near an intersection and is a position where guidance such as a course change such as a right turn or a left turn is performed. If it is determined in step S410 that there is guidance at the guidance position (step S410: Yes), it is determined whether or not the current position is near the destination (step S411). If it is determined in step S411 that the current position is near the destination (step S411: Yes), the final image of the design image information is displayed (step S412), and the design mode display is terminated (step S413).

  Then, map information is selected (step S414), the normal mode is displayed (step S415), and the series of processes is terminated. On the other hand, in step S406, when there is no guidance for “for a while” (step S406: No), the process proceeds to step S402. In Step S410, when it is determined that there is no guidance at the guidance position (Step S410: No), the process proceeds to Step S402. If it is determined in step S411 that the current position is not near the destination (step S411: No), the process proceeds to step S402.

  In the above-described navigation processing, it is assumed that the destination is set. However, the present invention is not limited to this. Even when the destination is not set, the mode can be switched in the same manner. it can. In step S403, whether or not the map information is to be displayed to the user is determined based on whether or not it is within a predetermined distance from the home. Based on this, for example, it may be determined whether there is a road that has passed a predetermined number of times within a predetermined period in the past. Further, the mode may be switched as appropriate by an operation input by the user. Although details will be described later, when the design mode is interrupted and restarted, information about the interrupt position of the design image information at the time of the interruption is stored before and after the interruption of the design mode. A continuous image is displayed.

  Further, when the above-described navigation processing is applied to the information display processing of the information display device, for example, the mode is not switched according to the current position of the vehicle, but is switched to the design mode by a user operation input. At the same time, a design mode that changes only in accordance with the traveling speed of the vehicle may be displayed.

(An example of processing for storing information about the interruption position of design image information when the design mode is interrupted)
Next, an example of processing for storing design image information when the design mode is interrupted in the navigation processing according to the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart illustrating an example of processing for storing design image information when the design mode is interrupted in the navigation processing according to the present embodiment.

  In FIG. 5, the navigation device 300 is in the normal mode and is in a standby state until an instruction to start the design mode is received (step S501: No). When the instruction to start the design mode is received (step S501: Yes), The display 312 displays the design mode (step S502). Then, it is determined whether or not an instruction for switching to the normal mode has been received (step S503).

  In step S503, the design mode is displayed on the display 312 until an instruction to switch to the normal mode is received (step S503: No). In step S503, when an instruction to switch to the normal mode is received (step S503: Yes), information related to the interruption position of the design image information is stored (step S504). The display 312 displays the normal mode (step S505), and determines whether an instruction to switch to the design mode has been received (step S506).

  In step S506, the normal mode is displayed on the display 312 until an instruction to switch to the design mode is received (step S506: No). In step S506, when an instruction to switch to the design mode is received (step S506: Yes), the design mode is restarted based on the stored design image information (step S507), and a series of processing ends.

(Example of design mode variations)
Next, an example of design mode variations according to the present embodiment will be described with reference to FIG. FIG. 6 is an explanatory diagram illustrating an example of variations of the design mode according to the present embodiment.

  In FIG. 6, a road 601, a destination suggestion point 602, and a character display 603 are displayed on the display screen 600 displayed on the display 312. The road 601, the destination suggestion point 602, and the character display 603 displayed on the display screen 600 are images irrelevant to actual map information. In the display screen 600 shown in FIG. 6, the vehicle travels on the white line 601 a of the road 601 and an image is displayed. In the display screen 600, a flag is displayed as a destination suggestion point 602 at a distance from the road 601. For example, the destination suggestion point 602 is displayed so as to be gradually positioned closer to the destination as the vehicle approaches the destination.

  The character display 603 is an arbitrary character, and may be any character such as hiragana, katakana, kanji, numbers, alphabets, Arabic characters, Greek characters, symbols, pictograms, and the like. The character display 603 moves on the display screen 600 sequentially from the top to the bottom, for example, and the moving speed changes according to the speed of the vehicle. Specifically, the character display 603 indicates that the character moving speed is slow when the vehicle is traveling at a low speed, and the character moving speed is fast when the vehicle is traveling at a high speed. ing. The character displayed on the character display 603 is, for example, an image generated based on a random number, and there is no regularity in how characters are arranged.

  Next, an example of design mode variations according to the present embodiment will be described with reference to FIG. FIG. 7 is an explanatory diagram showing an example of the final image of the variation shown in FIG.

  In FIG. 7, the display screen 600 displays a final image indicating that the destination suggestion point 602 is located on the near side and has reached the vicinity of the destination. The final image may be any image that allows the user to recognize the completion of the design mode. For example, the color of the flag may be changed, the flag may fall on the road 601, or the flag changes to the final image. What is necessary is just to change the degree of.

  In such a variation, when the destination is not set, for example, only the character display 603 may be displayed without displaying the destination suggestion point 602. In such a variation, the destination suggestion point 602 is not displayed in accordance with the distance to the destination, but is displayed in accordance with the time to reach the destination. The display may be moved to the front.

  According to such a variation, design image information corresponding to the speed of the vehicle can be easily displayed while suppressing the recording capacity of the magnetic disk 305 or the optical disk 307. Note that the image information of the road 601 and the white line 601a is displayed as a 3D image of the navigation device 300, and in this variation, a road at an arbitrary position different from the vehicle position is displayed. Therefore, it is not necessary to record new image information for the road 601 and the white line 601a.

(Example of design mode variations)
Next, an example of design mode variations according to the present embodiment will be described with reference to FIG. FIG. 8 is an explanatory diagram illustrating an example of variations of the design mode according to the present embodiment. The variation shown in FIG. 8 is a variation displayed by radar.

  In FIG. 8, a display screen 800 displayed on the display 312 displays a concentric circle 801, a current position 802, and a destination suggestion point 803. The concentric circles 801, the current position 802, and the destination suggestion point 803 displayed on the display screen 800 are images unrelated to the actual map information.

  The concentric circles 801 are decorative lines, and the intervals and scales of the concentric circles 801 are irrelevant to the actual map information. Realistic display is achieved by performing a rotational scan on the concentric circles. The current position 802 and the destination suggestion point 803 are displayed with a predetermined interval. The destination suggestion point 803 is displayed so as to gradually approach the current position 802 as the vehicle approaches the destination, for example.

  Next, an example of the final image in the design mode according to the present embodiment will be described with reference to FIG. FIG. 9 is an explanatory diagram showing an example of the final image of the variation shown in FIG.

  In FIG. 9, the display screen 800 displays a final image indicating that the destination suggestion point 803 coincides with the current position 802 and has reached the vicinity of the destination. In the final image, the color of the destination suggestion point 803 may be changed, or the destination suggestion point 803 may be blinked.

  In such a variation, the destination suggestion point 803 may be made closer to the current position 802 depending on the time until the destination is reached. Further, when the destination is not set, the rotational scanning speed on the concentric circles displayed on the display screen 800 may be changed according to the speed of the vehicle.

(Example of design mode variations)
Next, an example of design mode variations according to the present embodiment will be described with reference to FIG. FIG. 10 is an explanatory diagram illustrating an example of variations of the design mode according to the present embodiment. FIG. 10 shows a radar-displayed variation similar to FIG. 8, but is different from the version shown in FIG. 8 in that a passing point is displayed.

  In FIG. 10, a display screen 1000 displayed on the display 312 shows a radar display, and displays a concentric circle 1001, a current position 1002, and a passing point 1003 (1003a to 1003f). The concentric circle 1001, the current position 1002, and the passing point 1003 displayed on the display screen 1000 are images unrelated to the actual map information. The passing points 1003a to 1003f are arbitrary waypoints (for example, existing A intersection to F intersection) on the route to the destination, and the waypoints are randomly arranged on the concentric circle 1001. Therefore, the passage points 1003a to 1003f are arranged at points that are not related at all in the positional relationship with the points on the actual map information.

  Next, an example of a change in design mode according to the present embodiment will be described with reference to FIG. FIG. 11 is an explanatory diagram showing an example of variations of the variation shown in FIG.

  For example, it is assumed that the actual route of the vehicle passes in the order of passing points 1003a to 1003f. When the vehicle actually travels and approaches the actual A intersection, the passing point 1003a approaches the current position 1002 on the display screen 1000. When the vehicle passes through the A intersection, the passing point 1003a matches the current position 1002 and disappears on the display screen 1000. Similarly, every time the vehicle passes through the actual B intersection to F intersection, the passing points 1003b to 1003f approach the current position 1002 on the display screen 1000 and disappear when they coincide with the current position 1002. Note that the last passing point 1003f may be a destination.

  In such a variation, it is possible to further enhance entertainment by displaying points other than the destination and the waypoints. For example, the manufacturer displays in advance a point that is displayed when radar display is performed with respect to a specific existing point (for example, sightseeing spot X). The sightseeing spot X is not displayed as a specific point in the normal mode. Therefore, from the user's perspective, it is unclear where the set specific point actually exists on the radar-displayed screen.

  On the other hand, on the radar-displayed screen, for example, a specific point that is displayed lights up or a specific point approaches the current position 1002 as it approaches within a predetermined range from the sightseeing spot X. Inform the user that they are approaching the point. Then, when the tourist spot X is reached, the specific spot displayed disappears, for example, so that the user knows that the spot that has been set corresponds to the tourist spot X. In this way, by setting a plurality of points to be displayed in the radar display in, for example, various parts of Japan or all over the world in advance, it is possible to display an image that does not make the user more tired. .

  With such a configuration, a more designable image can be displayed in the design mode, and an image that is less tired can be displayed to the user.

(Example of design mode variations)
Next, an example of design mode variations according to the present embodiment will be described with reference to FIG. FIG. 12 is an explanatory diagram illustrating an example of variations of the design mode according to the present embodiment. The variation shown in FIG. 12 is a variation in which a specific figure is formed in a chain based on a certain rule.

  In FIG. 12, a chaos graphic 1201 is displayed on the display screen 1200 displayed on the display 312. This figure is formed according to a certain equation, and similar figures are continuously formed. The chaotic figure 1201 also changes the speed of the figure formed according to the speed of the vehicle. Specifically, when the vehicle is traveling at a low speed, the speed of the formed chaotic figure 1201 is reduced, while when the vehicle is traveling at a high speed, the speed of the formed chaotic figure 1201 is increased. Become.

  Next, an example of a change in design mode according to the present embodiment will be described with reference to FIG. FIG. 13 is an explanatory diagram showing an example of variation of the variation shown in FIG.

  As shown in FIG. 13, for example, as the vehicle approaches the destination, the chaos figure 1201 displayed on the display screen 1200 becomes larger. In the final image, the chaotic figure 1201 is displayed on the entire display screen 1200, for example, and becomes a plain image. The final image may be any image that allows the user to recognize the completion of the design mode. For example, the color of the chaotic figure 1201 may be changed.

  With such a configuration, it is possible to easily display a more designable image while suppressing the recording capacity of the magnetic disk 305 or the optical disk 307.

(Example of design mode variations)
Next, an example of design mode variations according to the present embodiment will be described with reference to FIG. FIG. 14 is an explanatory diagram illustrating an example of variations of the design mode according to the present embodiment. The variation shown in FIG. 14 is a variation for drawing a predetermined illustration.

  In FIG. 14, a display screen 1400 displayed on the display 312 describes a drawing unit 1401 and a locus 1402. The drawing unit 1401 draws, for example, with a single stroke according to the speed of the vehicle. Specifically, the drawing unit 1401 decreases the drawing speed if the vehicle is traveling at a low speed, and increases the drawing speed if the vehicle is traveling at a high speed. A locus 1402 is a locus that the drawing unit 1401 has passed.

  Next, an example of the final image in the design mode according to the present embodiment will be described with reference to FIG. FIG. 15 is an explanatory diagram showing an example of the final image of the variation shown in FIG.

  In FIG. 15, a predetermined illustration 1500 is drawn on the display screen 1400, and a final image indicating that the vicinity of the destination is reached is displayed. In the final image, it may be displayed such that the illustration is colored or the illustration itself moves.

  In such a variation of drawing an illustration, an illustration drawn by a user may be used. Specifically, the image information of the illustration read by the scanner may be received, and the illustration may be drawn based on this image information. Further, a photographic image may be drawn based on image information of a photograph taken with a digital camera or the like. In this case, according to the speed of the vehicle, a contour may be drawn and a final colored image may be formed.

  With such a configuration, a more designable image can be displayed in the design mode, and an image that is less tired can be displayed to the user.

  As described above, according to the navigation device 300 according to the present embodiment, the display 312 is either the normal mode in which the map information is displayed or the design mode in which the design image information that changes according to the running state of the vehicle is displayed. Display either of them. Therefore, when display of map information is unnecessary, the design mode can be displayed, and the display can be used effectively. In addition, the user does not need to turn off the navigation device 300 when map display is unnecessary on a familiar road or the like. Furthermore, the user can be prevented from getting bored with the display screen by displaying an entertaining image without displaying a monotonous map image. Therefore, the user can enjoy driving without feeling the taste of the display screen.

  Moreover, according to the navigation apparatus 300 concerning a present Example, the speed of the vehicle was detected and the design image information was changed according to the detected speed of the vehicle. Therefore, since the design image information is changed according to the constantly changing vehicle speed, the display 312 can display a variety of design image information.

  Further, according to the navigation device 300 according to the present embodiment, the current position of the vehicle is specified, and the determination result of determining whether to switch the display mode of the display 312 based on the specified current position of the vehicle. Based on the above, either map information or design image information is selected. That is, the display mode is switched based on the determination whether the current position is within a predetermined distance range from the home or the current position is an expressway. With such a configuration, the display mode can be switched as appropriate according to the current position of the vehicle without the user performing an operation input. Therefore, in the vicinity of homes where there is no need to watch the map with caution, users can be distracted by looking at the design mode even when they feel stress due to traffic jams or waiting for traffic lights. Leads to the enforcement of

  Further, according to the navigation device 300 according to the present embodiment, the traveling history of the vehicle is acquired, and it is determined whether or not to switch the display mode of the display 312 based on the acquired traveling history. May be. With such a configuration, the display mode of the display 312 can be switched based on, for example, whether or not the currently traveling road has traveled a predetermined number of times in the past from the acquired travel history. Therefore, the display 312 can be switched to the design mode at a place familiar to the user.

  Further, according to the navigation device 300 according to the present embodiment, guidance is appropriately performed in the vicinity of the branch position or the guidance position on the route to the destination, and the normal mode or the design mode is switched based on the guidance. You may make it judge whether it performs. With such a configuration, the display 312 can be switched from the design mode to the normal mode when there is guidance for a change of course such as a right turn or a left turn in the vicinity of an intersection or the like. Therefore, even if the display 312 is in the design mode, the user can appropriately obtain guidance information because the display 312 is appropriately switched to the normal mode. In addition, when there is a guidance “for a while”, the user can switch from the normal mode to the design mode without performing an operation input. Therefore, it is possible to notify the user of guidance information as appropriate, and furthermore, since the display mode is switched according to the guidance, the guidance is sharpened and the guidance information can be conveyed more appropriately.

  Further, according to the navigation device 300 of the present embodiment, when the design mode is interrupted, information related to the interrupt position of the design image information when the design mode is interrupted is stored. Then, when the design mode is resumed, the design image information is changed to be continuous with the design image information based on the information about the interruption position of the stored design image information. The display 312 displays continuous images before and after the design mode is interrupted. With such a configuration, even when the design mode is interrupted, the design image information is continuously displayed before the interruption after the restart of the design mode, so the same image is displayed every time the design mode is restarted. The display screen can be used more effectively even in the design mode.

  Further, according to the navigation device 300 according to the present embodiment, the distance to the destination is calculated, the design image information is determined according to the calculated distance to the destination and when the destination is reached. Changed to be the final image. As described above, since the design image information is changed according to the distance to the destination, the user can grasp the rough distance to the destination. In addition, by displaying the final image before reaching the destination, the user can recognize that the user is located near the destination.

  Further, according to the navigation device 300 according to the present embodiment, the time to the destination may be calculated, and the design image information may be changed according to the calculated time to the destination. Thus, by changing the design image information according to the time to the destination, the user can grasp the rough arrival time to the destination. In addition, by displaying the final image before reaching the destination, the user can recognize that the user is located near the destination.

  Moreover, according to the navigation apparatus 300 concerning a present Example, the design image information of several different variations was memorize | stored. Accordingly, design image information rich in variations can be displayed without always displaying the same design image information. Therefore, since the user can select a variation according to his / her preference, he can obtain more entertainment and can be prevented from getting bored with the display screen.

  The navigation device 300 according to the present embodiment can also be applied to an information display device. In this case, the design image information may be simply changed according to the running state of the vehicle. Therefore, by displaying an image having a design property, the user can be prevented from getting bored with the display screen even on a familiar road or the like.

  Further, according to the information display device, the navigation device 300 according to the present embodiment is in either the normal mode in which the map information is displayed or the design mode in which the design image information that changes according to the traveling state of the moving object is displayed. You may make it switch. With such a configuration, when display of map information is unnecessary, the design mode can be displayed, and the display can be used effectively. Therefore, the user can enjoy driving without feeling the taste of the display screen.

  As described above, according to the navigation device, the navigation method, the navigation program, the recording medium, the information display device, and the information display method of the present invention, the navigation device 300 can be used in the normal mode in which the map information is displayed or the vehicle travels. One of the design modes in which the design image information that changes according to the state is displayed is displayed. Therefore, when the display of the map information is unnecessary, the design mode in which the design image information is displayed can be displayed. As a result, the user can suppress annoyance caused by the display of a monotonous screen with a map on a familiar road, etc., and perform a comfortable driving without getting tired of the display screen. Can do.

  Note that the navigation method and information display method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. Further, this program may be a transmission medium that can be distributed via a network such as the Internet.
