Hereinafter, an embodiment of the electronic map device of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration diagram of the present invention. In this figure, 1 is an antenna, 2 is a GPS receiver, 3 is a gyro compass, 4 is a camera, 5 is a microphone, 6 is a memory, 7 is a central processing unit, 8 is a map information database, 9 is a display, and 10 is a touch panel. The screen 11 is a speaker. Here, the GPS receiver 2 calculates the longitude and latitude of the current location from the signal from the GPS satellite received by the antenna 1 and outputs the calculated longitude and latitude to the central processing unit 8. The gyro compass 3 is attached to the camera 4, detects the direction of the subject from the camera 4, and outputs the direction to the central processing unit 7. However, when both the gyro compass 3 and the camera 4 are fixed to the vehicle body as in the case of a vehicle, it is not necessary that the gyro compass 3 and the camera 4 are fixed in contact with each other, and they are installed so that they face in the same direction. Just fine. When the operator takes a picture of the surrounding scenery using the camera 4, the photographed image information is sent to the central processing unit 7. At this time, the central processing unit 7 sends the longitude and current position of the current location from the GPS receiver 2. The latitude and the direction of the subject are obtained from the gyro compass 3 and recorded in the memory 6 as a set with the image information. Similarly, when voice is recorded using the microphone 5, the recorded voice information is sent to the central processing unit 7, and at this time, the central processing unit 7 obtains the longitude and latitude of the current location from the GPS receiver and And recorded in the memory 6 as a set with the audio information.

FIG. 2 shows an example of a method for storing image information and audio information in the memory 6. Here, the longitude and the latitude are represented by seven-digit integers as follows. For example, a method of expressing a point at 139 degrees 48 minutes 45.0 seconds east longitude and 35 degrees 42 minutes 30.0 seconds north latitude is shown in (Equation 1).

　図３はディスプレイ９の画面上における地図表示の例を示したものであり、画面の表面にはタッチスクリーン１０が組み込まれており、画面上には地図情報データベース９に従って地図を表示するが、ＧＰＳ受信機２より得られた現在地の経度・緯度を中心として表示し、現在地が移動すると共に地図の表示範囲も移動する。この時、地図の中心には現在地を表す円に囲まれた矢印の記号を表示しているが、この矢印の方向はジャイロコンパス３により検出されたカメラの方向を示している。この実施例では、ある位置において画像情報が記録されていることを示す記号として矢印使用しており、この記号の表示される向
きにより撮影されたときの方位、すなわちカメラから被写体への方角がわかるようになっている。また、音声情報が記録されていることを示す記号として白丸を使用している。そして、操作者がタッチスクリーン１０に触れるなどして画面上に示された矢印や丸の記号を選択（後に詳しく説明する）したときは、触れられたタッチスクリーン１０上の座標から、地図上の実際の経度と緯度とをそれぞれ求め、その位置で採集された画像情報や音声情報を再生する（選択された記号が表している情報を再生する）。

FIG. 3 shows an example of a map display on the screen of the display 9. A touch screen 10 is incorporated on the surface of the screen, and a map is displayed on the screen according to the map information database 9. The longitude and latitude of the current position obtained from the receiver 2 are displayed as the center, and the display position of the map moves as the current position moves. At this time, an arrow symbol surrounded by a circle representing the current location is displayed at the center of the map, and the direction of the arrow indicates the direction of the camera detected by the gyrocompass 3. In this embodiment, an arrow is used as a symbol indicating that image information is recorded at a certain position, and the azimuth at the time of shooting, that is, the direction from the camera to the subject, can be known according to the displayed direction of the symbol. It has become. A white circle is used as a symbol indicating that audio information is recorded. Then, when the operator touches the touch screen 10 or the like to select an arrow or a circle symbol shown on the screen (to be described in detail later), the coordinates on the touch screen 10 that are touched indicate The actual longitude and latitude are obtained, and the image information and audio information collected at that position are reproduced (the information represented by the selected symbol is reproduced).

FIG. 4 is an example of the output of image information when the arrow at the lower left of the screen in FIG. 3 is selected. The map information is zoomed up from the position of the selected symbol by using the overlap window. The image information is displayed above.

FIG. 5 also shows an example of image information output when the arrow at the lower left of the screen in FIG. 3 is selected. In this example, a window for image information is constantly displayed separately from the map, and the arrow on the map is displayed. The output image information is switched each time a symbol is selected.

Now, a method of selecting a symbol using the touch screen 10 is as follows. The position when the operator's finger starts touching the touch screen 10 installed on the display 9 or the position when the touched finger separates is described. It is assumed that a distance is detected from this position to a symbol displayed at a position closest to the detected position on the touch screen 10, and a symbol is selected when this distance is smaller than a certain value.

時 に は Also, when a plurality of symbols are displayed in a concentrated manner as indicated by the arrow at the lower right of FIG. 3, it is difficult to select using the above method. In such a case, the user slides the finger on the touch screen 10 while touching it as described below, inputs not only coordinate information but also angle information, and selects a symbol having different angle information to be held. Here, n symbols are concentrated, and their positions on the screen are represented by (x1, y1), (x2, y2),. . . , (Xn, yn) and the angle information of those symbols are D1, D2,. . . , Dn (the direction of the arrow on the map corresponds to this angle information). First, the position (x1, y1) when the user starts touching the touch screen 10 and the position (x2, y2) of the finger after a predetermined time are detected, and the moving direction d of the finger is obtained by the following (Equation 2).

　そして求められたｄとＤ１，Ｄ２，．．．，Ｄｎとを比較し、最も差の小さいものがＤｉであったならば、ｉ番目の記号が選択されたとする。

Then, the obtained d and D1, D2,. . . , Dn, and if the one with the smallest difference is Di, it is assumed that the i-th symbol has been selected.

FIG. 6 is a configuration diagram of the embodiment shown in FIG. 1 in which the map information database 8, the display 9, the touch screen 10, the speaker 11, and other parts necessary for map display, image information, and audio information output have been removed. In this figure, 701 is an antenna, 702 is a GPS receiver, 703 is a gyro compass, 704 is a camera, 705 is a microphone, 706 is a memory, and 707 is a central processing unit. When only information is collected using the camera 704 and the microphone 705, such a minimal configuration is suitable for carrying.

As described in detail above, according to the present embodiment, the following effects can be obtained.

(1) Since the position information is recorded at the same time that the operator inputs the image information of the surrounding scenery and the voice information to be read out, the recorded image information and voice information are displayed on the map as symbols. be able to.

(2) By designating these symbols on the map, images and sounds recorded at the place can be reproduced, so that the memory at the time of visiting the place can be recalled.

(3) When the recording person and the reproducing person are different, the reproducing person can preliminarily image the atmosphere of the place from the reproduced information even though he / she has never visited the place, and thus visits an unknown land. It can remove the feeling of anxiety at the time.

 As described above, according to the present invention, when video information is input, the location information of the point is detected and recorded, so that the recorded video information can be used.
