  According to this technique, the menus of all layers up to the upper layer can be displayed, but the menu display width of the upper layer may be changed by the menu of the lower layer. Further, when the menu hierarchy is deep, the menu is displayed over the entire width of the screen. For this reason, it results in forcing the operator to move the line of sight irregularly, and is hidden in the menu.

  Therefore, an object of the present invention is to provide an image display method that enables menu display with improved visibility for an operator in a navigation apparatus that displays a map screen for guidance.

To solve the above problems, an image display method according to the present invention, the map screen to be displayed in perspective projection, a plurality of hierarchies, the image display method of the hierarchical navigation device that displays a menu consisting of the group of icons The navigation device displays a higher-level icon group in response to an operator input or system input request, and the navigation device corresponds to a lower-level icon in response to an operator icon selection from the icon group. A hierarchy icon group is displayed, and the navigation device moves the display position of the upper hierarchy icon group to the vanishing point position of the map screen displayed accordingly.

In this way, when the navigation device moves the display position of the upper-level icon group, it may be moved so that the selected icon is positioned at the vanishing point position.

In addition, the navigation device may display the lower-level icon group at the approximate center of the display screen.

It is preferable that the navigation device displays the icons of the lower hierarchy icon group with an accent display different from the upper hierarchy icons.

  According to the present invention, at the stage of displaying the menu of the lower hierarchy, the menu of the upper hierarchy is moved to the vanishing point position of the map screen displayed by the perspective projection, so that the operator's viewpoint when moving the menu hierarchy Movement is reduced. In addition, since the menu can be displayed at the top of the map display, the visibility of the map display is not impaired even during the menu display.

  By moving the selected icon to the vanishing point position, it can be seen at a glance which icon has been selected, and thus the visibility is further improved. By displaying the lower-level icon group at the approximate center of the display screen, the menu to be selected can be easily viewed.

  Visibility is further improved by displaying the lower-level and upper-level icon groups with different accent displays.

It is a block diagram which shows the structure of the display apparatus which implement | achieves the image display method which concerns on this invention. It is a flowchart explaining the image display method which concerns on this invention. It is a figure which shows the state which is displaying the 1st hierarchy of a menu. It is a figure which shows the state which displays the 2nd hierarchy of a menu.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings. In order to facilitate the understanding of the description, the same reference numerals are given to the same components in the drawings as much as possible, and duplicate descriptions are omitted.

  FIG. 1 is a block diagram showing a configuration of a display device for realizing an image display method according to the present invention. This display device is a navigation device mounted on a vehicle, and is configured around a navigation ECU 10 that is a control device. The navigation ECU 10 includes a CPU, a ROM, a RAM, and the like, and a GPS receiver 13 that receives data from a GPS (Global Positioning System) satellite by an antenna 14 and a map database (DB) 11 that is a storage device that stores map information. In addition to the gyro device 12, which is an autonomous navigation device, various vehicle state quantity sensors 18 for detecting vehicle speed, acceleration, steering angle, etc., an input means 17 for setting menus, a display 15 for displaying, and a voice output A speaker 16 is connected.

  Here, by using a touch panel display, the input unit 17 and the display 15 may be used together. In the following embodiment, a case of using this type of touch panel display will be described as an example. The present invention is suitable when the input means 17 different from the display 15 is used.

  This navigation device estimates the current position of the host vehicle from information from GPS satellites received by the GPS receiver 13, the vehicle state quantity acquired by the vehicle state quantity sensor 18, and the output of the gyro device 12, and from the map DB 11 It has a function of reading out map information at a corresponding position and displaying it on the display 15. Further, a route to the destination is obtained based on the traffic information read from the map DB 11 and the surrounding area information according to the destination information set by the input means 17, and the route information to the destination is obtained according to the current position. It has a function of displaying on the display 15. At this time, voice guidance may be performed by the speaker 16.

  FIG. 2 is an example of a map screen displayed on the display 15 by the navigation device. The map display is displayed in a perspective view or a bird's eye view format, and the vehicle position is displayed with an icon 100 in which a triangle is arranged in a circle, and one of the vertices of the triangle is the traveling direction of the vehicle Represents.

A predetermined menu 100 is displayed on the display screen of the display 15 when the operation of the operator or the navigation device requests input by the operator (see FIG. 3). Here, the map screen itself is displayed. menu 110 is arranged not as screen upward icon ₁₁₀ a to 110 _E be blocking the display of a surrounding of a vehicle icon 100 in the form of side-by-side. In Figure 3, although written in all the icon 110 _A to 110 _E circle, in fact, each visually its features intuitive icon display is used.

In this state, when the operator selects the icon 110 _B menu 120 in the lower hierarchy is associated, the screen is changed as shown in FIG. Specifically, the menu 110 of the upper layer, are both selected icon 110 _B moves in the upper portion of the screen to match the vanishing point 130 the position of the displayed map, a menu 120 of the new lower layer menu 110 before movement is Displayed at the displayed position. This menu 120 is comprised of an icon ₁₂₀ A to 120 _D.

In this case, menu 110 has a narrow height from the menu 120 while moving, or when the size of each icon ₁₁₀ A to 110 _E is animated to be smaller than the size of the icon ₁₂₀ A to 120 _D. Further, the constituent elements of the menu 110 (including icons 110 _{A to} 110 _E ) are displayed lighter than the constituent elements of the menu 120, and only the selected icon 110 _B is displayed from 110 _A and 110 _{C to} 110 _E from the other icons. It should be highlighted. Furthermore, it is preferable to return to the display state shown in FIG. 3 by touching any one of the upper level menus 110.

By performing the display in this way, the operator feels that the menu 120 of the upper hierarchy is moved to the back of the screen by the selection of the icon 110 _B and the menu 120 is displayed in the foreground. The line of sight movement can be suppressed and the relationship between the menu 110 and the menu 120 can be easily understood. Furthermore, since the menus 110 and 120 do not block the main part of the map display (particularly, the display around the vehicle icon 100), both operability and visibility can be achieved.

  In this menu display, display is performed without screen transition by superimposing the display on these displays as a layer separate from the map display screen and other information displays. For this reason, there is an advantage that the flow of the operation of the operator is not interrupted and that the operator can intuitively understand that the operator can easily return to the previous use screen.

The display of the higher-level menu 110 displayed on the back side is not limited to the above display state, but an accent display different from the lower-level menu 120 displayed on the front side may be performed. At this time, as the context of the icons 110 _B and menu 120 selected understandable visually, to associate a display of both display icon 110 _B (e.g. color) may associate a display of the menu 110.

  Here, a two-level menu has been described as an example. However, when the number of hierarchies extends to three or more levels, the same method may be used for display. In the case of three or more layers, when a lower layer is displayed by selecting an item in the lower layer menu, the layer menu previously displayed at the vanishing point position is the back of the screen, that is, It is good to move it further above the vanishing point position. Alternatively, the hierarchical menu may be deleted from the screen.
