[0007] また、上記特許文献 1の場合、携帯端末装置の場合を問わず、従来、表示画面に 表示させている情報の優先度と、表示画面のレイアウトとの関係が考慮されていなか つた。したがって、複数の情報を確認するために表示画面内の各表示箇所を見なけ ればならな力つた。このような表示画面は、視点移動が多いために、閲覧する利用者 に負担がかかると!、う問題が一例として挙げられて 、る。 [0007] Further, in the case of Patent Document 1, the relationship between the priority of information displayed on the display screen and the layout of the display screen has not been considered conventionally, regardless of the case of the mobile terminal device. Therefore, it was necessary to see each display location in the display screen in order to confirm multiple information. Such a display screen has many viewpoint movements, and it can be a burden on the user to browse!

[0014] 以下に添付図面を参照して、この発明にかかる経路誘導装置、経路誘導方法、経 路誘導プログラムおよび記録媒体の好適な実施の形態を詳細に説明する。 Hereinafter, preferred embodiments of a route guidance device, a route guidance method, a route guidance program, and a recording medium according to the present invention will be described in detail with reference to the accompanying drawings.
[0015] (経路誘導装置の機能的構成) [0015] (Functional configuration of route guidance device)
まず、この発明の実施の形態に力かる経路誘導装置の機能的構成について説明 する。図 1は、この発明の本実施の形態の経路誘導装置の機能的構成の一例を示 すブロック図である。図 1のように、この発明の実施の形態に力かる経路誘導装置 10 0は、生成部 101と、表示制御部 102と、検出部 103とを含んで構成される。さらに、 表示制御部 102は、取得部 104と、レイアウト部 105とを含んで構成される。また、経 路誘導装置 100には、設定された目的地への経路を誘導する地図画像を表示させ る表示画面 110が接続されている。経路とは、利用者によって設定された目的地まで の道筋を経路探索装置により検索して得られた誘導経路である。 First, the functional configuration of the route guidance apparatus according to the embodiment of the present invention will be described. FIG. 1 is a block diagram showing an example of a functional configuration of the route guidance device according to the present embodiment of the present invention. As shown in FIG. 1, a route guidance apparatus 100 according to the embodiment of the present invention includes a generation unit 101, a display control unit 102, and a detection unit 103. Further, the display control unit 102 includes an acquisition unit 104 and a layout unit 105. The route guidance device 100 is connected to a display screen 110 that displays a map image for guiding a route to a set destination. A route is a guidance route obtained by searching a route to a destination set by a user using a route search device.
[0016] 生成部 101は、表示画面 110に表示させる誘導情報を生成する。誘導情報とは、 経路誘導装置 100を搭載した移動体の現在地点前方の誘導経路上に存在する複 数の交差点または分岐点における進行すべき方向を示す画像である。なお、以下便 宜上交差点または分岐点の双方の意味を含めて「分岐点」とよぶ。 The generation unit 101 generates guidance information to be displayed on the display screen 110. The guidance information is an image indicating the direction to travel at a plurality of intersections or branching points existing on the guidance route ahead of the current location of the moving body on which the route guidance device 100 is mounted. In the following, for the sake of convenience, the meaning of both an intersection and a branch point will be referred to as a “branch point”.
[0017] ここで、誘導画像について詳しく説明する。誘導画像とは、右左折方向をあらわす 矢印や、文字力もなる画像である。具体的には、たとえば、矢印からなる誘導画像は 、特定された進行方向を向いて誘導経路走行した場合に、実際に利用者が右左折 する方向を示した矢印の画像により構成されている。また、矢印があらわす方向は、 単純に右、左、斜め右、斜め左のみでもよいが、実際の分岐点における誘導経路の 形状に合わせた矢印の画像を生成してもよ 、。 [0017] Here, the induced image will be described in detail. A guidance image is an image that also shows an arrow indicating the direction of turning left and right, and a character. Specifically, for example, a guidance image composed of arrows is configured by an arrow image that indicates the direction in which the user actually turns right and left when traveling on a specified route in the specified traveling direction. The direction of the arrow may be simply right, left, diagonal right, or diagonal left, but it is also possible to generate an arrow image that matches the shape of the guidance route at the actual branch point.
[0018] なお、生成部 101において、矢印を実際の誘導経路とどれだけ類似した形状の矢 印の誘導画像を生成できるかは、生成部 101に提供される分岐点に関する情報 (詳 しくは、段落番号 [0021]で説明する)の精度に依存する。また、あまりに実際の形状 と類似させた矢印の画像を生成しても、利用者が瞬時に右左折判断をおこなうには 適さない矢印の画像になってしまう場合もある。したがって、基本的には、単純な形
状の矢印の画像を生成するように設定する。その後、利用者が適宜、生成する矢印 の画像の形状のノリエーシヨンを設定し、最適な画像を生成するようにしてもよ!、。 [0018] It should be noted that how much the arrow can generate a guide image of an arrow having a shape similar to the actual guide path in the generation unit 101 is information on a branch point provided to the generation unit 101 (more specifically, Depends on the accuracy of paragraph number [0021]. Moreover, even if an arrow image that is too similar to the actual shape is generated, the arrow image may not be suitable for the user to make a right or left turn instantaneously. Therefore, basically, simple form To generate an image of the arrow. After that, the user may set the nomination of the shape of the arrow image to be generated as appropriate to generate the optimal image!
[0019] また、文字からなる誘導画像は、利用者が右左折する方向を示したアルファベット や漢字の映像によって構成されている。具体的には、たとえば、右折をあらわす「R」 、「右」、左折をあらわす「L]、「左」の画像が生成される。また、斜め右や斜め左をあ らわす場合には、基本的な斜めをあらわす文字を追加してもよいし、文字自体を実際 の分岐の形状に合わせて傾けた画像を生成してもよい。 [0019] In addition, the guidance image made up of characters is composed of images of alphabets and kanji that indicate the direction in which the user turns left and right. Specifically, for example, “R”, “right” representing a right turn, and “L”, “left” representing a left turn are generated. In addition, when representing diagonally right or diagonally left, you may add a basic diagonal character or generate an image with the character itself tilted to match the actual branch shape. .
[0020] また、上述した矢印や文字による誘導画像の他に、利用者によって右左折をあらわ す画像を生成するように個別に設定してもよい。たとえば、生成部 101が、分岐点に 関する情報として分岐点付近の進行すべき方向の目印となるランドマークの画像情 報を取得した場合、このランドマークの画像情報を誘導画像として利用してもよい。こ のように、利用者ごとに誘導画像の内容を設定可能であるため、各利用者それぞれ が最も認識しやす 、誘導画像を生成することができる。 [0020] Further, in addition to the above-described guidance image with arrows and characters, the user may individually set so as to generate an image showing a left or right turn. For example, when the generation unit 101 acquires image information of a landmark that is a landmark in the direction to travel near the branch point as information about the branch point, the image information of the landmark may be used as a guide image. Good. In this way, since the content of the guidance image can be set for each user, the guidance image can be generated most easily for each user.
[0021] なお、生成部 101は、誘導画像を生成するために、誘導経路から分岐点に関する 情報を取得している。分岐点に関する情報とは、分岐点の位置情報、右左折情報を 含んだ情報である。また、分岐点に関する情報とは、上述の情報に加えて、分岐点の 名称 (たとえば、「X〇小学校前」、「口町三丁目」など)情報や、分岐点の目印となる ランドマークの画像情報などを含んでもよい。これらの分岐点に関する情報は、誘導 経路の地図画像力 抽出される。 [0021] Note that the generation unit 101 acquires information about a branch point from the guidance route in order to generate a guidance image. The information on the branch point is information including the position information of the branch point and the left / right turn information. In addition to the above-mentioned information, the information related to the branch point includes information on the name of the branch point (for example, “X 〇 Elementary School”, “Kuchimachi 3-chome”), and the landmark that serves as the landmark of the branch point. Image information and the like may be included. Information about these bifurcation points is extracted from the map image power of the guidance route.
[0022] また、生成部 101において誘導画像を生成するには、上述した分岐点に関する情 報とともに、現在地点の情報が必要となる。したがって、生成部 101には、移動体の 現在地点の情報が提供されている。この現在地点の情報とは、経路誘導装置 100の 利用者が現在位置する場所をあらわす情報である。具体的には、たとえば、緯度経 度情報が提供される。また緯度経度情報以外にも所定の基準点に対応した座標情 報が提供されてもよい。 [0022] In addition, in order to generate a guide image in the generation unit 101, information on the current location is required in addition to the information on the branch point described above. Therefore, the generation unit 101 is provided with information on the current location of the moving object. The current location information is information indicating the location where the user of the route guidance device 100 is currently located. Specifically, for example, latitude and longitude information is provided. In addition to the latitude and longitude information, coordinate information corresponding to a predetermined reference point may be provided.
[0023] なお、現在地点を検出する手法として、たとえば、 GPS (Global Positioning Sy stem)信号を受信して現在地点を検出する手法が挙げられる。 GPS信号を用いた 手法の場合、経路誘導装置 100に GPS信号レシーバを備え、この GPSレシーバに
より受信した GPS信号に基づいて、緯度経度情報を算出する。また、 GPS信号を受 信する手法の他に、携帯電話や PHS (Personal Handy -phone System)の通 信基地局情報を利用して現在地点を検出する手法などがあり、どの手法を利用して ちょい。 [0023] As a method for detecting the current location, for example, there is a method for detecting the current location by receiving a GPS (Global Positioning System) signal. In the case of a method using GPS signals, the route guidance device 100 is equipped with a GPS signal receiver, Latitude and longitude information is calculated based on the received GPS signal. In addition to the method of receiving GPS signals, there is a method of detecting the current location using communication base station information of mobile phones and PHS (Personal Handy-phone System), which method is used. A little.
[0024] 表示制御部 102は、移動体が誘導経路に沿って移動した場合に、生成部 101によ つて生成された誘導画像を分岐点に到達する順序に配列して表示画面 110に表示 させる。また、表示制御部 102は、移動体が生成部 101により生成した誘導画像の中 の一の誘導画像に対応する分岐点を通過した場合に、この一の誘導画像を表示画 面 110から消去させてもよい。表示制御部 102は、この消去処理とともに、表示画面 110に表示されて 、な 、あらたな誘導画像を分岐点に到達する順序に応じて配列し て表示させる。 [0024] When the moving body moves along the guidance route, the display control unit 102 arranges the guidance images generated by the generation unit 101 in the order in which they reach the branch point, and displays them on the display screen 110. . In addition, when the moving body passes through a branch point corresponding to one of the guide images generated by the generation unit 101, the display control unit 102 deletes the one guide image from the display screen 110. May be. The display control unit 102 displays the new guidance image arranged in accordance with the order of arrival at the branch point, which is displayed on the display screen 110 together with the erasing process.
[0025] また、表示制御部 102は、移動体の走行位置の移動に応じて表示画面 110上で、 誘導画像をスクロールさせることもできる。このような表示制御をおこなう場合には、生 成部 101に提供されている現在地点の情報における等時間間隔の変化量を検出し 、各時間間隔における現在地点の変化量を算出して速度を検出すればよい。または 、移動体に、検出部 103を備えてもよい。検出部 103は、移動体の走行速度を検出 する。この検出部 103により検出された走行速度に応じて誘導画像をスクロールさせ ることがでさる。 [0025] The display control unit 102 can also scroll the guide image on the display screen 110 in accordance with the movement of the traveling position of the moving object. When such display control is performed, the amount of change at equal time intervals in the current point information provided to the generation unit 101 is detected, and the amount of change at the current point at each time interval is calculated to calculate the speed. What is necessary is just to detect. Alternatively, the detection unit 103 may be provided in the moving body. The detection unit 103 detects the traveling speed of the moving body. The guide image can be scrolled in accordance with the traveling speed detected by the detecting unit 103.
[0026] また、表示制御部 102は、表示画面 110の表示領域を分割して任意の画像を表示 させるために、取得部 104と、レイアウト部 105とを備えてもよい。取得部 104は、移 動体の前方の地図画像を設定された目的地へ誘導する地図画像を取得する。レイ アウト部 105は、誘導画像を取得部 104により取得した地図画像と同じ表示画面に 表示させるように表示画面 110の表示領域を左右に分割する。そして。分割した一の 表示領域に生成部 101により生成した誘導画像を表示させるように設定し、他の表 示領域に取得部 104により取得した地図画像を表示させるように設定する。 [0026] The display control unit 102 may include an acquisition unit 104 and a layout unit 105 in order to divide the display area of the display screen 110 and display an arbitrary image. The acquisition unit 104 acquires a map image that guides the map image ahead of the moving object to the set destination. The layout unit 105 divides the display area of the display screen 110 into left and right so that the guide image is displayed on the same display screen as the map image acquired by the acquisition unit 104. And then. The guide image generated by the generation unit 101 is set to be displayed in one divided display area, and the map image acquired by the acquisition unit 104 is set to be displayed in another display area.
[0027] また、表示制御部 102は、生成部 101により生成された誘導画像を走行位置の前 方の誘導経路順に配置して表示させる。誘導経路順とは、現在地点から目的地まで 誘導経路を走行した場合に、利用者が到達する分岐点の順序である。また、誘導画
像の配置は、単純に等間隔で配置させてもよいが、好ましくは、実際の分岐点間の 距離を縮尺した間隔で表示させるとともに、走行位置が分岐点に近づくごとに、当該 分岐点の誘導画像をレイアウト部 105により設定した表示領域の下方へ移動するよう に表示させるとよい。このような表示により、つぎの分岐点までの距離を利用者に直 感的に確認させることができる。 [0027] Further, the display control unit 102 arranges and displays the guidance images generated by the generation unit 101 in the order of the guidance route in front of the traveling position. The guide route order is the order of the branch points that the user reaches when traveling on the guide route from the current point to the destination. In addition, induction image The images may be simply arranged at equal intervals, but preferably, the distance between the actual branch points is displayed at a reduced interval, and each time the traveling position approaches the branch point, The guide image may be displayed so as to move downward in the display area set by the layout unit 105. Such a display allows the user to intuitively confirm the distance to the next branch point.
[0028] また、誘導経路順に配置させた誘導画像は、生成部 101にお 、て、分岐点の数だ け生成されている力 誘導経路の全長や、表示の縮尺設定によっては、すべての誘 導画像を同時に表示画面 110に表示できない。したがって、表示制御部 102は、誘 導経路順に所定の数の誘導画像だけ表示させてもよい。 [0028] In addition, the guide images arranged in the order of the guide routes are all generated by the generation unit 101 depending on the total length of the force guide routes generated by the number of branch points and the scale setting of the display. The derived image cannot be displayed on the display screen 110 at the same time. Therefore, the display control unit 102 may display only a predetermined number of guide images in the order of the guide route.
[0029] また、表示制御部 102は、上述したように、レイアウト部 105により表示画面 110の 表示領域を左右に分割し、一方の誘導画像を、他方に地図画像を表示させることが できるが、さらに、一方の表示領域の下方には、誘導画像のうち、走行位置から所定 の距離以内の分岐点の誘導画像を表示させるように制御してもよい。同時に、他方 の表示領域の下方には、地図情報のうちの走行位置直近の地図画像を表示させる ように制御する。 [0029] Further, as described above, the display control unit 102 can divide the display area of the display screen 110 into left and right by the layout unit 105, and can display one guide image and a map image on the other. Further, below the one display area, control may be performed so that a guide image of a branch point within a predetermined distance from the travel position is displayed among the guide images. At the same time, control is performed so that the map image closest to the traveling position in the map information is displayed below the other display area.
[0030] 上述のような表示制御をおこなうことにより、表示制御部 102は、誘導経路を確認す るために今すぐに必要な、現在地点の直前の情報を表示画面 110の下方に集中し て表示させることができる。利用者は、今すぐに必要な情報を確認するには、表示領 域の下方を注目すればよぐ無用な視点移動を必要としない。また、利用者がどのよ うな角度で表示画面 110を見ている力、どのような進行方向であるかに応じて走行位 置周辺の情報を、表示領域の上方に集中させるように制御してもよい。また、表示画 面 110を上下に分割した場合には、表示領域の右方または左方に走行位置周辺の 情報が集中するように制御してもよ 、。 [0030] By performing the display control as described above, the display control unit 102 concentrates the information immediately before the current point necessary for confirming the guidance route immediately below the display screen 110. Can be displayed. The user does not need an unnecessary viewpoint movement if he / she pays attention to the lower part of the display area in order to confirm the necessary information immediately. In addition, control is performed so that the information around the driving position is concentrated above the display area according to the angle at which the user views the display screen 110 and the direction of travel. Also good. In addition, when the display screen 110 is divided into upper and lower parts, it may be controlled so that information about the driving position is concentrated on the right or left side of the display area.
[0031] さらに利用者が誘導経路を認識しやすい表示をおこなうため、表示制御部 102は、 検出部 103により走行速度が検出される場合には、検出された走行速度に応じて誘 導画像のスクロールの速度を調整して表示させている。このように、実際の走行速度 とスクロールの速度とを調整することにより、利用者に、誘導情報以外にも走行速度 を視覚的にわかりやすぐまた、認識しやすい表示を実現することができる。
[0032] また、同じく利用者が誘導経路を認識しやすい表示をおこなうため、表示制御部 10 2は、誘導経路上のいずれかの分岐点が走行位置力も所定の距離以内に近づくと、 分岐点の誘導画像を拡大して表示させてもよ!ヽ。誘導画像を拡大する他にも誘導画 像の色合 、や濃度を変化させるなど、走行位置から所定の距離以内に近づ ヽた誘 導画像が重要な情報であることを認識させるような表示をおこなってもよい。 [0031] Further, in order to display the guide route so that the user can easily recognize the guidance route, the display control unit 102, when the detection unit 103 detects the traveling speed, displays the guidance image according to the detected traveling speed. The scroll speed is adjusted and displayed. In this way, by adjusting the actual traveling speed and the scrolling speed, it is possible to realize a display that allows the user to visually understand the traveling speed in addition to the guidance information and to easily recognize it. [0032] Further, in order to perform a display in which the user can easily recognize the guidance route, the display control unit 102, when any of the branch points on the guidance route approaches the travel position force within a predetermined distance, You can enlarge and display the guide image! In addition to magnifying the guide image, display such as changing the color or density of the guide image to recognize that the guide image approaching within a predetermined distance from the running position is important information. You may do it.
[0033] (経路誘導装置の処理の内容) [0033] (Processing contents of route guidance device)
つぎに、経路誘導装置 100の処理の内容について説明する。図 2は、経路誘導装 置の処理の内容の一例を示すフローチャートである。図 2のフローチャートにおいて、 まず、現在地点前方の経路上に分岐点がある力否かを判断する (ステップ S201)。こ こで、経路上に分岐点がない場合は (ステップ S201 :No)、誘導画像を表示させる 必要がないため、そのまま一連の処理を終了する。一方、ステップ S201において、 経路上に分岐点がある場合は (ステップ S201: Yes)、分岐点において進行すべき 方向をあらわす誘導画像を生成する (ステップ S202)。 Next, the processing contents of the route guidance device 100 will be described. FIG. 2 is a flowchart showing an example of the contents of processing of the route guidance device. In the flowchart of FIG. 2, first, it is determined whether or not there is a branch point on the route ahead of the current point (step S201). Here, when there is no branch point on the route (step S201: No), it is not necessary to display the guidance image, and thus the series of processing ends. On the other hand, if there is a branch point on the route in step S201 (step S201: Yes), a guidance image representing the direction to travel at the branch point is generated (step S202).
[0034] つぎに、経路上のすべての分岐点の誘導画像を生成したか否かを判断する (ステツ プ S203)。ここで、すべての分岐点の誘導画像を生成していない場合は (ステップ S 203 :No)、ステップ S202の処理に戻り、残りの分岐点の誘導画像を生成する。 Next, it is determined whether or not guide images of all branch points on the route have been generated (step S203). If the guidance images for all branch points have not been generated (step S 203: No), the process returns to step S 202 to generate the remaining branch point guidance images.
[0035] 一方、ステップ S203において、すべての分岐点の誘導画像を生成した場合は (ス テツプ S203 :Yes)、生成した誘導画像を到達順に配列し (ステップ S204)、現在地 点に応じて誘導画像を表示画面 110に表示する (ステップ S205)。 [0035] On the other hand, when the guidance images of all branch points are generated in step S203 (step S203: Yes), the generated guidance images are arranged in the order of arrival (step S204), and the guidance images are generated according to the current location. Is displayed on the display screen 110 (step S205).
[0036] そして、移動体の移動にともな 、、分岐点を通過したか否かを判断する (ステップ S 206)。ここで、移動体が分岐点を通過した場合は (ステップ S206 : Yes)、通過した 分岐点の誘導画像を表示画面 110から消去する (ステップ S 207)。なお、移動体が 分岐点を通過していない場合は(ステップ S 206 : No)、そのままステップ S208の処 理に移行する。 [0036] Then, as the moving body moves, it is determined whether or not the vehicle has passed a branch point (step S206). Here, when the moving body passes through the branch point (step S206: Yes), the guidance image of the branch point that passed is deleted from the display screen 110 (step S207). If the moving body has not passed the branch point (step S 206: No), the process proceeds to step S 208 as it is.
[0037] その後、移動体が目的地に到達したか否かを判断し (ステップ S208)、 目的地に到 達するまで、ステップ S205の処理に戻り、誘導画像の表示および消去を繰り返す (ス テツプ S208 :Noのループ)。ステップ S208において、移動体が目的地に到達したと 判断すると (ステップ S208 : Yes)、そのまま一連の処理を終了する。
[0038] 以上説明したように、本発明の実施の形態に力かる経路誘導装置 100は、分岐点 における進行すべき方向を認識させるために特ィ匕した誘導画像を生成することがで きる。また、誘導画像の表示を生成した誘導画像を、地図画像と同一の表示画面 11 0に表示させるとともに指定した表示領域 (たとえば、表示領域の下方)に重要な情報 が集中して表示されるように制御する。したがって、経路誘導をおこなうために重要な 情報のみを効果的に表示させることにより、利用者にとって認識しやすい表示画面 1 10を提供することができる。 [0037] Thereafter, it is determined whether or not the moving body has reached the destination (step S208), and the process returns to step S205 until the destination is reached, and the display and deletion of the guidance image are repeated (step S208). : No loop). If it is determined in step S208 that the moving body has reached the destination (step S208: Yes), the series of processing ends. [0038] As described above, the route guidance device 100 according to the embodiment of the present invention can generate a guidance image specialized for recognizing a direction to travel at a branch point. In addition, the guide image that generated the display of the guide image is displayed on the same display screen 110 as the map image, and important information is displayed in a concentrated manner in the specified display area (for example, below the display area). To control. Therefore, it is possible to provide a display screen 110 that is easy for the user to recognize by effectively displaying only important information for route guidance.
[0039] また、上述のように経路誘導装置 100は、重要な情報のみを効果的に表示させるこ とができる。したがって一般のナビゲーシヨン装置と比較して表示画面の小さな、携帯 端末装置などであっても、一瞥しただけで必要な情報が認識できるような誘導画像を 実現することができる。 [0039] Further, as described above, the route guidance device 100 can effectively display only important information. Therefore, even a portable terminal device having a display screen smaller than that of a general navigation device can realize a guidance image that can recognize necessary information with a glance.

Since the guidance points are arranged according to the distance between the branch points, the number displayed at one time changes appropriately according to the traveling position.
[0061] ·右左折距離 421 :走行位置力 直近の分岐点までの距離をあらわす [0061] · Left / Right turn distance 421: Running position force Indicates the distance to the nearest branch point
'誘導ポイント 422〜425:分岐点における右左折方向をあらわす 'Guiding points 422 to 425: Represents the direction of turning left or right at the junction.
[0062] また、携帯端末装置 300により走行位置の変化が検出されると、走行状態となり、 走行速度に応じて表示領域 410、 420ともに表示内容を変化させる。 [0062] In addition, when a change in the travel position is detected by mobile terminal device 300, a travel state is entered, and the display contents of display areas 410 and 420 are changed according to the travel speed.
[0063] 具体的には、表示領域 410では、走行に応じて走行位置ポイント 411が、ルート 41[0063] Specifically, in the display area 410, the travel position point 411 is displayed in accordance with the travel.
2を走行するように移動する。実際には、走行位置ポイント 411は、表示領域 410の 所定の位置に固定して表示されるため、ルート 412が表示領域 410の下方ヘスクロ ールして ヽくように表示される。 Move to drive 2. Actually, since the traveling position point 411 is fixedly displayed at a predetermined position in the display area 410, the route 412 is displayed so as to scroll down the display area 410.
[0064] また、表示領域 420では、走行に応じて右左折距離 421の数値が変化する。また、 誘導ポイント 422〜425は、通過済みの誘導ポイントは消去され、つぎに配置されて いる誘導ポイントが、 Omの位置に表示される。
[0065] 具体的に説明すると、走行位置ポイント 411が、直近分岐点 413を通過すると、誘 導ポイント 422は消去され、誘導ポイント 423が Omの位置に配置される。また、誘導 ポイント 425の後方に配置された誘導ポイントが、誘導ポイント 423との距離に応じて 適宜表示される。このように、走行に応じて誘導ポイント 422〜425は、表示領域 420 の上方から下方へ落下するように表示される。 [0064] In the display area 420, the numerical value of the left / right turn distance 421 changes according to the traveling. In addition, for the guidance points 422 to 425, the guidance points that have been passed are erased, and the guidance point that is arranged next is displayed at the position of Om. More specifically, when the traveling position point 411 passes through the latest branch point 413, the guidance point 422 is deleted, and the guidance point 423 is arranged at the position of Om. In addition, a guidance point arranged behind the guidance point 425 is appropriately displayed according to the distance from the guidance point 423. As described above, the guidance points 422 to 425 are displayed so as to fall from the upper side to the lower side of the display area 420 in accordance with traveling.
[0066] なお、上述した 2つの表示領域 410、 420と独立して目的地までの距離を表示する 表示領域 401と、到着予定時刻を表示する表示領域 402とがそれぞれ設定されてい る。このように、表示領域 400は、重要な情報が下方に集中して表示されるように設 定されている。 [0066] It should be noted that a display area 401 for displaying the distance to the destination independently of the two display areas 410 and 420 described above and a display area 402 for displaying the estimated arrival time are set. As described above, the display area 400 is set so that important information is concentrated and displayed downward.
[0067] (経路誘導画面の画像表示処理の内容) [0067] (Contents of image display processing of route guidance screen)
つぎに、携帯端末装置 300により図 4の表示領域 400に示したような経路誘導画面 を表示させるための具体的な処理の内容について詳細に説明する。図 5は、経路誘 導画面の画像表示処理の内容の一例を示すフローチャートである。図 5のフローチヤ ートにおいて、まず、携帯端末装置 300の現在地を測位し (ステップ S501)、現在地 の半径 50m以内に探索したルートがある力否かを判断する(ステップ S502)。 Next, details of specific processing for displaying the route guidance screen as shown in the display area 400 of FIG. 4 by the mobile terminal device 300 will be described in detail. FIG. 5 is a flowchart showing an example of the contents of the route guidance screen image display processing. In the flowchart of FIG. 5, first, the current location of the mobile terminal device 300 is measured (step S501), and it is determined whether or not there is a route searched within a radius of 50 m of the current location (step S502).
[0068] ステップ S502において、現在地の半径 50m以内に探索したルートがない場合に は (ステップ S502 :No)、ステップ 501に戻り、再度現在地を測位する処理に移行す る (ステップ S501)。一方、現在地の半径 50m以内に探索したルートがある場合には (ステップ S502 : Yes)、現在地とルートとのルートマッチングをおこなう(ステップ S50 [0068] In step S502, if there is no route searched for within the radius of 50 m of the current location (step S502: No), the process returns to step 501 and shifts to the process of positioning the current location again (step S501). On the other hand, if there is a searched route within the radius of 50m of the current location (Step S502: Yes), route matching between the current location and the route is performed (Step S50).
3)。 3).
[0069] つぎに、ルートマッチングにより特定したルートの進行方向を決定する(ステップ S5 [0069] Next, the traveling direction of the route specified by route matching is determined (step S5).
04)。さらに、現在地の地図を、決定した進行方向を基準にヘディングアップ表示さ せる (ステップ S505)。ヘディングアップ表示とは、基準とした方向が上を向くように表 示させる表示手法である。したがって、ステップ S505の処理〖こより、地図画像は、右 左折によって適宜回転して、常に進行方向が上を向くように表示される。 04). Further, a map of the current location is displayed with a heading up based on the determined traveling direction (step S505). Heading-up display is a display method that displays the reference direction upward. Therefore, the map image is displayed so that the direction of travel always faces upward by rotating right and left as appropriate from the processing in step S505.
[0070] その後、現在地から表示可能距離内(図 4の場合、約 lkm以内)の誘導ポイントの 情報を取得すると (ステップ S506)、取得した誘導ポイントを距離順に配列し (ステツ プ S507)、現在地からの距離に応じて誘導ポイントを表示させる(ステップ S508)。
[0071] 続いて、現在地の半径 100m以内に誘導ポイントがあるか否かを判断し (ステップ S 509)、半径 100m以内に誘導ポイントがある場合には (ステップ S509 : Yes)、半径 1 OOm以内に該当する誘導ポイントを拡大して表示させる (ステップ S 510)。 [0070] After that, when information on guidance points within the displayable distance from the current location (within approximately lkm in the case of Fig. 4) is obtained (step S506), the obtained guidance points are arranged in order of distance (step S507), and the current location is obtained. The guidance point is displayed according to the distance from (step S508). [0071] Next, it is determined whether there is a guidance point within a radius of 100 m of the current location (step S 509). If there is a guidance point within a radius of 100 m (step S 509: Yes), the radius is within 1 OOm. The guidance point corresponding to is enlarged and displayed (step S 510).
[0072] ステップ S510の処理が終了した、もしくは、半径 100m以内に誘導ポイントがなか つた場合には (ステップ S509 : No)、続いて、経路誘導が終了したか否かを判断する (ステップ S511)。ステップ S511の判断により経路誘導が継続中であると判断された 場合は (ステップ S511 :No)、ステップ S501の処理に戻り、再度、表示処理をおこな う。一方、経路誘導が終了した場合には (ステップ S511 : Yes)、そのまま一連の表示 処理を終了する。 [0072] When the process of step S510 is completed, or there is no guidance point within a radius of 100 m (step S509: No), it is subsequently determined whether or not the route guidance is completed (step S511). . If it is determined in step S511 that the route guidance is continuing (step S511: No), the process returns to step S501 and the display process is performed again. On the other hand, when the route guidance is finished (step S511: Yes), the series of display processing is finished as it is.
[0073] なお、図 5に示したステップ S502における現在地からの半径の値や、ステップ S50 9における現在地からの半径の値は、一例であって、利用者により適宜変更させ、認 識しゃす 、表示に近づけることができる。 [0073] The value of the radius from the current location in step S502 and the value of the radius from the current location in step S509 shown in FIG. 5 are examples, and may be changed as appropriate by the user, recognized, and displayed. Can be approached.
[0074] (各表示領域を連動させた表示処理) [0074] (Display processing that links each display area)
つぎに、各表示領域 (表示領域 410、 420)を連動させた表示処理について説明す る。図 4のような地図画像の表示領域 410と、誘導画像の表示領域 420とは双方の表 示内容を連動させた表示処理をおこなうこともできる。 Next, display processing in which the display areas (display areas 410 and 420) are linked will be described. The display area 410 of the map image as shown in FIG. 4 and the display area 420 of the guide image can also perform display processing in which the display contents of both are linked.
[0075] 具体的には、表示領域 420に表示したいずれかの誘導ポイントに対して利用者か らの指定を受け付けると、表示領域 410は、指定された誘導ポイントに対応する分岐 点の地図画像を表示させるような表示処理をおこなうことができる。 [0075] Specifically, when a designation from the user is received for any of the guidance points displayed in display area 420, display area 410 displays a map image of the branch point corresponding to the designated guidance point. Can be displayed.
[0076] 図 6は、各表示領域を連動させた表示処理の内容の一例を示すフローチャートで ある。図 6のフローチャートにおいて、まず、利用者から誘導ポイントの指定を受け付 けたか否かを判断する (ステップ S601)。ここで、指定を受け付けると (ステップ S601 : Yes)、指定された誘導ポイントの緯度経度情報を取得する (ステップ S602)。なお 、ステップ S601において、指定を受け付けなかった場合は(ステップ S601 :No)、表 示領域 410には通常通り現在地に対応した地図画像を表示させるため、ステップ S6 06の処理に移行する。 FIG. 6 is a flowchart showing an example of the contents of display processing in which the display areas are linked. In the flowchart of FIG. 6, it is first determined whether or not the designation of the guidance point has been received from the user (step S601). Here, when designation is accepted (step S601: Yes), the latitude / longitude information of the designated guidance point is acquired (step S602). If the designation is not accepted in step S601 (step S601: No), the display area 410 is displayed in the display area 410 as usual, so that the process proceeds to step S606.
[0077] つぎに、取得した緯度経度におけるルートの進行方向を決定し (ステップ S603)、 さらに、取得した緯度経度の地図情報を、ステップ S603において決定した進行方向
を基準にしてヘディングアップ表示する(ステップ S604)。 [0077] Next, the traveling direction of the route at the acquired latitude and longitude is determined (step S603). Further, the acquired latitude and longitude map information is determined as the traveling direction determined at step S603. The heading-up display is performed with reference to (Step S604).
[0078] そして、ステップ S604によるヘディングアップ表示がおこなわれてから所定時間経 過した力否かを判断する (ステップ S605)。ここで、所定時間経過するまで待ち (ステ ップ S605 :Noのループ)、経過すると(ステップ S605 :Yes)、現在地の地図画像を 、進行方向を基準にしてヘディングアップ表示して (ステップ S606)—連の処理を終 了する。以上説明したような処理をおこなうことにより、利用者は、指定した誘導ポイン トが実際にどのような道路であるかを確認することができる。 Then, it is determined whether or not the force has passed for a predetermined time since the heading-up display in step S604 was performed (step S605). Here, it waits until the predetermined time elapses (step S605: No loop), and when it elapses (step S605: Yes), the map image of the current location is displayed in a heading-up based on the traveling direction (step S606). —End the sequence. By performing the processing as described above, the user can confirm what kind of road the specified guidance point is actually.
[0079] (経路誘導画面の表示例) [0079] (Example of route guidance screen display)
つぎに、経路誘導画面の他の表示例について説明する。図 7は、経路誘導画面の 他の表示例を示す説明図である。図 7に表示例 710、 720、 730、 740として表示し たように様々な表示を設定することができる。 Next, another display example of the route guidance screen will be described.

A display example 710 is a route guidance screen that displays the guidance points 711 to 713 configured with kanji characters so that they fall one after another. Also, the display example 720 is a route guidance screen displayed so that the guidance points 721 to 723 constituted by English initials (L, R) representing left and right fall one after another.
[0081] 表示例 710、 720に示したような漢字やアルファベットを用いた誘導ポイント 422〜 425を表示させることにより、矢印を実際の方向をあらわす言葉に変換する処理を省 くことができる。本実施例のように、運転者に対して携帯端末装置 300の利用者であ る他の搭乗者が右左折方向を指示する作業が必要となる場合、搭乗者による右左折 方向の言い間違いを防ぐことができる。 [0081] Displaying guidance points 422 to 425 using kanji and alphabets as shown in display examples 710 and 720 makes it possible to omit the process of converting the arrow into a word indicating the actual direction. As in this example, when the other passenger who is the user of the mobile terminal device 300 needs to instruct the driver to turn right or left, the passenger may mistakenly say the right or left turn. Can be prevented.
[0082] また、図 7の表示例 730、 740は、あらたな付加情報を加えた経路誘導画面である 。表示例 730は、誘導ポイント 731〜733のうち、特定の情報を含んだ誘導ポイント 7 32は、色彩を変化させて表示させる。特定の情報とは、ルートの中間地付近をあらわ す情報や、所定の距離ごとに設定された休憩箇所をあらわす情報、一般道路と有料 道路との切り替え地点のあらわす情報などが挙げられる。またこれらの情報の他にも 、利用者によって任意に設定した情報を付加することもできる。 In addition, display examples 730 and 740 in FIG. 7 are route guidance screens to which new additional information is added. In the display example 730, among the guidance points 731 to 733, the guidance point 732 including specific information is displayed by changing the color. Specific information includes information that represents the vicinity of the route midway, information that represents a break point set for each predetermined distance, and information that represents a switching point between a general road and a toll road. In addition to these information, information arbitrarily set by the user can be added.
[0083] また、表示例 740は、道路の通行状況を表示する機能を備えた表示をあらわして!/、
る。携帯端末装置 300が、通信 IZF313を用いて渋滞情報を取得した場合に、ルー ト 412に渋滞箇所をあらわす警告ポイント 741を追加して表示させるとともに、警告ポ イント 741に該当する区域 742も、渋滞をあらわすために、他の区間と異なる色で表 示させる。 [0083] In addition, display example 740 represents a display having a function of displaying road traffic conditions! /, The When the mobile terminal device 300 acquires traffic jam information using the communication IZF313, a warning point 741 indicating the traffic jam location is added to the route 412 and displayed, and the area 742 corresponding to the warning point 741 is also jammed. In order to display, it is displayed in a different color from other sections.
[0084] また、図 7に示した表示例の他にも、 1キロより先の誘導ポイントは、画面上に表示さ れている最も遠い誘導ポイント (たとえば図 4に示した誘導ポイント 425)に、まとめて 重ねて表示させてもよい。さらに、この際に、どの位の数の誘導ポイントが重ねられて いるかを把握できるように表示させてもよい。このような表示をおこなうことにより、利用 者は、あと何回右左折をおこなえば目的地に到達するかを視覚的に確認することが できる。 [0084] In addition to the display example shown in FIG. 7, the guide point beyond 1 kilometer is the farthest guide point displayed on the screen (for example, guide point 425 shown in FIG. 4). , You may display them all together. Furthermore, at this time, it may be displayed so that it is possible to grasp how many guidance points are overlapped. By performing such a display, the user can visually confirm how many more left and right turns to reach the destination.
[0085] 以上説明したように、本実施例によれば、携帯端末装置 300のディスプレイ 311で あっても、経路誘導に必要な情報を利用者が容易に認識できるように表示させること ができる。 As described above, according to the present embodiment, even the display 311 of the mobile terminal device 300 can display information necessary for route guidance so that the user can easily recognize it.
[0086] なお、本実施の形態で説明した経路誘導方法は、あら力じめ用意されたプログラム をパーソナル 'コンピュータやワークステーションなどのコンピュータで実行することに より実現することができる。このプログラムは、ハードディスク、フレキシブルディスク、 CD-ROM, MO、 DVDなどのコンピュータで読み取り可能な記録媒体に記録され 、コンピュータによって記録媒体力も読み出されることによって実行される。またこの プログラムは、インターネットなどのネットワークを介して配布することが可能な伝送媒 体であってもよい。
