According to the present invention, the scroll speed and the scroll direction are changed according to the existing POI, so that the map scroll operation can be simplified and the POI can be reached quickly.

Embodiments of the present invention will be described below.
FIG. 1 is a block diagram showing an example of a map display device according to this embodiment. The control device 1 is composed of a personal computer or the like, and includes a drawing processing means 1a comprising a drawing processing application that develops map data into drawing data (bitmap data), and a detection for detecting a scroll operation by a touch panel touch operation or a remote control operation. Means 1b, control means 1c for controlling each means, control for scrolling the map, and the like are provided. The drawing processing means 1a reads the map data stored in the map data storage device 4 for storing the map data including the POI data, develops the map data on a VRAM (not shown) built in the control device, and performs control. The drawing data is scrolled by a method such as moving the reading area of the bitmap data under the control of the means 1c or redrawing so that each dot position of the bitmap data is shifted. The detection unit 1b detects a scroll operation by the scroll operation device 2 including a touch panel and a remote controller, and the detection result is taken into the control unit 1c and becomes data for determining the scroll direction.

  The control means 1c outputs the drawing data including the current position information detected by the current position detection device 3 to the display device 5 to display the map, and when the scrolling operation is detected by the detection means 1b, the scrolled drawing data is displayed. Is output to the display device 5 and displayed on a map. Control is performed so that automatic scrolling and a certain length of scrolling are performed according to the operation mode of the scroll operation device. For example, when a touch panel is used as the scroll operation device, the touch time is automatically set to a predetermined time, for example, 1 second or more. Scrolling for a fixed length is performed in less than 1 second. In order to stop scrolling in the case of automatic scrolling, an arbitrary method may be selected, such as scrolling again during scrolling, or providing a scroll stop button and operating it. Further, the control unit 1c retrieves the POI from the drawing data to be displayed, and changes the scroll speed and the scroll direction according to the existing POI.

  Further, when the POI is set as the destination, the control unit 1c counts the set number for each genre of the POI and stores the count value in the storage device 4. The POI set as the destination may include a POI that is highly likely to be determined as a destination, such as a POI searched by a user or a POI registered as a point, in addition to a POI actually determined as a destination. Good. When a plurality of POIs exist nearby when scrolling, the count value is read to determine whether the POI is a genre that is often set as a destination, and a genre that is often set as a destination. In the case of the POI, scrolling is performed so as to be drawn toward the POI. Also, the control means 1c vibrates the display screen when the user approaches the POI of the genre that is often set as the destination during scrolling, and informs that the user has approached the POI of the genre that is often set as the destination. The current position detection device 3 obtains the current position from sensor outputs of a GPS (Global Positioning System) receiver, an acceleration sensor, a speed sensor, a rudder angle sensor, and the like. The display device 5 has a structure in which, for example, the touch panel 2 is disposed on the front surface of the liquid crystal display panel. In this case, the touch panel and the display device 5 are integrated.

FIG. 2 is a diagram illustrating an example of a screen for determining the scroll direction.
In the present embodiment, the screen is divided into eight areas a to h with the center O of the display screen as a base point, and the scroll direction is determined depending on which area is selected by the scroll operation device. For example, when the areas a and e are selected, the screen is scrolled up and down, when the areas c and g are selected, the screen is scrolled left and right, and the areas b, f, d, and h are selected. Scrolls diagonally. Of course, the method of dividing the screen area is not limited to this example, and the screen area may be divided more finely or coarsely.

Next, an example of screen scrolling will be described with reference to FIGS. Below, in order to make it easy to understand the relative movement between the map and the screen by scrolling, the description will be given as an expression in which the map is fixed for convenience and moved on the screen.
FIG. 3 is a diagram for explaining automatic scrolling.
The reference numeral 10 on the screen A1 is the current position or the vehicle position mark, and the point P on the right end of the screen A1 is selected by the scroll operation device. For example, in the case of a touch panel, the point P is touched for a certain time (for example, When the finger is released after 1 second), a linear automatic scroll is performed in the right direction, and the screen is scrolled as shown in screen B1 after t1 seconds by scroll S1 (arrow), and then screen C1 is displayed after t2 seconds by scroll S2 (arrow). Scrolled.

FIG. 4 is a diagram illustrating an example in which the automatic scrolling is terminated when the POI reaches the center area of the screen.
When the right end P point of the screen A2 is touched with a scroll operation device, for example, a touch panel and the finger is released after a predetermined time, the linear automatic scrolling is performed in the right direction, and the screen scrolls to the screen B2 after t3 seconds by the scroll S3 (arrow). Since the POI “GS” (gas station mark) exists slightly above the right end of the screen B2, the scroll direction of the next scroll S4 (arrow) is changed diagonally upward, and the POI is t4 seconds later. Scrolling ends at the timing of screen C2 when “GS” reaches the center of the screen.

FIG. 5 is a diagram illustrating an example in which the scroll speed is increased in a place where the POI is small and the scroll speed is decreased in a place where the POI is large.
When the right end P of the screen A3 is touched with a scroll operation device, for example, a touch panel, and the finger is released after a predetermined time, the linear automatic scrolling is performed in the right direction. Is scrolled to the screen B3 after t5 seconds. There is a POI “GS” slightly above the right edge of this screen B3, and in the next scroll S6 there are many POIs such as post offices, gas stations, banks, etc., so the scroll speed is slowed down like the scroll S6 (arrow). , Sucrose to screen C3 after t6 seconds. Note that the scrolling speed may be changed depending on the presence of the POI according to the number of POIs entering the display area, the degree of congestion, the type of POI, the degree of POI recognition, the degree of popularity, and the like.

FIG. 6 is a diagram for explaining an example of changing the scroll direction so that the POI is drawn in that direction when there is a POI.
When a finger touches the upper right P point of the right end of the screen A4 with a scroll operation device, for example, a touch panel, and then releases the finger after a certain time, a linear automatic scroll S7 (arrow) in the upper right direction occurs, and the screen B4 is scrolled after t7 seconds. Is done. The POI “GS” exists slightly below the right edge of the screen B4. In the next scroll S8 (arrow), POIs such as post offices, gas stations, and banks exist at the bottom of the screen, so that the POI enters the display area. The scroll direction is changed and scrolling to the lower right is performed, and the screen C4 is displayed after t8 seconds. In the illustrated case, the scroll speed of the scroll S8 is larger than that of the scroll S7, but the scroll speed may be changed without changing the scroll speed. Further, the scrolling may be terminated when the area where the POIs are concentrated reaches the center of the screen.

FIG. 7 is a diagram for explaining an example of scrolling so that a user is attracted to a genre POI often set as a destination when a plurality of POIs exist nearby.
When the right end P point of the screen A5 is touched with a scroll operation device, for example, a touch panel, and the finger is released after a predetermined time, a linear automatic scroll S9 (arrow) in the right direction is generated, and the screen B5 is scrolled after t9 seconds. The If the POI “GS” exists on the right end side of the screen B5 and there are a plurality of POIs such as a post office and a Japanese restaurant nearby, and the “Japanese restaurant” is a POI of a genre that is often set as a destination, Scroll S10 (arrow) is performed so as to be drawn to the “Japanese restaurant”, and screen C5 appears after t10 seconds. Whether or not the genre is often set as the destination, every time the POI is set as the destination, the set number of counts is counted for each genre and held in the storage device, and the count value is read by the control means. It is determined whether or not the genre is set as the destination. Specifically, a genre set as a destination more than a predetermined number of times is determined as a genre that is often set as a destination. The predetermined number of times may be fixed, or may vary at a ratio to the total number of times the destination is set. When there are a plurality of POIs of genres that are often set as destinations, for example, scrolling so that the nearer POI is given priority or the POI on the side where the vehicle is traveling is given priority is drawn. . Further, in the illustrated case, the scroll speed of the scroll S10 is larger than that of the scroll S9. However, the scroll speed may be changed without changing the scroll speed, and the “Japanese restaurant” store is located at the center of the screen. Scrolling may end when it reaches.

FIG. 8 is a diagram illustrating an example in which the screen is vibrated and notified when the user approaches a POI of a genre that is often set as a destination during scrolling.
When the right end P point of the screen A6 is touched with a scroll operation device, for example, a touch panel, and the finger is released after a predetermined time, a linear automatic scroll S11 (arrow) in the right direction is generated, and the screen B6 is scrolled after t11 seconds. The Assume that there is a POI “GS” on the right end side of the screen B6, and a post office and a bank that are POIs of a genre that is often set as a destination. When approaching this POI during scrolling (S11 or S12 (arrow)), the control means vibrates the screen and notifies that the POI of the genre to be set as the destination is approaching. In this case, scrolling may be performed so as to be drawn to the post office or bank, and scrolling may be terminated when the post office or bank reaches the center of the screen.
