Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-vehicle navigation device for operating and selecting a desired destination and a point to be referred to at a high speed in a car navigation map screen displayed three-dimensionally.

[0002]

2. Description of the Related Art Hitherto, a bird's-eye view map is known in a car navigation system in which map data is three-dimensionally processed, viewed from a certain viewpoint, and a map expressing a sense of depth in the map is three-dimensionally displayed. Such a bird's-eye view map is shown in FIG.
7 is generally used. The bird's-eye view map shown in FIG. 27 is indicated by a cursor E1, an object E2 drawn on the map, and a road E3. When a user wants to select a desired point by using this bird's-eye view map, a method of selecting a certain point in the map is as follows. With the cursor fixed at the center of the display screen, the map is scrolled to move the cursor to the desired point. In general, a method of moving to the center and selecting a destination from the screen is used.

[0003] Next, the operation of the vehicle-mounted navigation device shown in FIG. 27 will be described with reference to FIG. FIG. 28 shows a scroll operation when the cursor E1 is arranged at the center of the screen. In FIG. 28, since the screen is scrolled in the depth direction, the object E2 and the road E3, which are the contents of the screen, are displayed in chronological order. (A), (B),
They move toward you in the order of (C).

When the viewpoint position of the bird's-eye map is changed, such as altitude, the elevation angle and altitude data based on the viewpoint origin position of the bird's-eye map are changed, three-dimensional processing is performed again, and redrawing is performed. Things are common. If you want to rotate the entire map around the viewpoint,
Similarly, three-dimensional processing is performed again to execute redrawing. Here, an operation example of the three-dimensional processing of the bird's-eye view map will be described with reference to FIG. FIG. 29A shows a display screen of a reference bird's-eye view map, FIG. 29B shows a display example in which the viewpoint height is raised, and FIG. 29C shows a display example in which the viewpoint height is lowered.
(D) shows a display example in which the map is rotated leftward about the viewpoint position, and (E) shows a display example in which the map is rotated rightward about the viewpoint position.

However, in the above-described bird's-eye map processing method, it is necessary to continuously perform complicated three-dimensional arithmetic processing when scrolling the screen as compared with the arithmetic processing for drawing a planar map. In the case where a desired point is selected while scrolling the map, there is a problem that the scrolling speed is reduced due to the processing time required for redrawing, and the operation may be inconvenient.

In order to solve such a problem, conventionally, in scroll drawing of a bird's-eye map, when scrolling the map, the time interval of redrawing is extended, the number of times of redrawing is reduced, or scrolling is performed. A method of increasing the speed of scroll drawing of a bird's eye map by taking measures such as reducing the number of drawing objects has been generally used. However, as disclosed in JP-A-9-229706, the cursor itself arranged on the map plane is moved to a desired point on the map plane, and the moved cursor position corresponds to the origin of the map display. By redrawing the three-dimensional map in such a manner, a means for reducing the number of calculation processes for each scroll of the three-dimensional map by moving the cursor and increasing the speed of redrawing the scroll to a desired destination in the three-dimensional map has been proposed. I have.

Referring to FIG. 30, the above-mentioned conventional navigation device is disclosed in Japanese Patent Laid-Open No. 9-22970.
The scroll redrawing method disclosed in Japanese Patent Publication No. 6 will be described. In FIG. 30, (A) of FIG. 30 shows a state before the cursor is moved, and (B) of FIG.
(C) of 0 schematically shows the navigation display screen after the cursor is moved. Further, FIG. 30 shows a bird's-eye view map E4 drawn from a viewpoint viewed from above by performing a three-dimensional drawing process on the electronic map data, a ruled line E5 for easily grasping a scale, a straight line E6 indicating a road, and an intersection E7.
And an object E8 indicating a landmark or a building, a cursor E9 for selecting a display origin, a cursor E10 moved to a point selected as the next display origin, and a moved cursor position to the origin of the bird's-eye map drawing. A cursor E11 is shown.

With this configuration, while scrolling from the cursor position E9 in FIG. 30A to the cursor position E10 in FIG. 30B, the cursor is moved without performing the redrawing process in the middle. By redrawing the later position E11 as the center of the next bird's-eye map,
It is possible to reduce the number of times of redrawing due to scrolling.

[0009]

However, in the above-described conventional on-vehicle navigation device, the operation of scrolling the map or moving the cursor is different from the operation of changing the viewpoint position of the bird's-eye map. Therefore, since these operations cannot be performed at the same time, there is a problem that redrawing takes time.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problem. The operation of moving the cursor position on a bird's-eye view map and the operation of moving the cursor in the line of sight are performed simultaneously to move the cursor and change the line of sight. The present invention provides an excellent in-vehicle navigation device capable of increasing the speed of a vehicle.

[0011]

According to the present invention, there is provided an on-vehicle navigation apparatus which displays a bird's-eye view map obtained by three-dimensionally processing map data to be drawn extracted from a map information storage means so as to be viewed from an upper viewpoint by a signal processing means.
