DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information display device suitable for use in a vehicle navigation device having a function of inputting points such as a destination and a passing point.

[0002]

2. Description of the Related Art In a vehicular navigation apparatus mounted on an automobile or the like, when an arbitrary point is input and a destination or a passing point is set, an input by a code number, an input by a map coordinate, and the like can be performed. An entry of a registration point by a genre search, an entry by a telephone number, and the like are used. For example, addresses, stations, government offices, intersections, airports,
In the entry of registered points by genre search such as port, police station, parking lot, hospital, etc., first, when a genre is selected, the names belonging to that genre are displayed in a tree structure in order from broad division and displayed according to each selection I do. In this case, the names to be selected are displayed in a list of a plurality of lines in the order of the Japanese syllabary, and the names are selected using a predetermined position in the list as a selection frame.

FIG. 11 is a diagram showing a conventional display example of scrolling a list in a selection frame. A navigation device having a point registration function has been proposed in Japanese Patent Application Laid-Open No. Hei 5-313573. When a destination such as a destination or a passing point is input, the input point is registered in the system. The input operation is facilitated by using the registered point from the next time. The example shown in FIG.
An example in which such point registration is performed by inputting, for example, an address is shown. Although this screen is not shown, when an address is selected on the place name index screen of the point registration, the prefecture and the main city are displayed in a selection frame in the order of the Japanese syllabary, and when the 23 wards of Tokyo are selected there, furthermore, Sumida-ku is moved to the selection frame position and displayed. "S", "S",
“Se” and “ta” are initials, the arrow on the left is an initial scroll button, the arrow on the right is a one-row scroll button, and when the initial scroll button is touched, the initial is “Shinjuku .., "Suginami-ku",... In order, for example, to the top line, and when the one-row scroll button is touched, the list is moved line by line.

[0004]

On the screen where names and the like are displayed in the selection frame in the order of the Japanese syllabary as described above, when moving (scrolling) one line at a time to search for a desired name,
Although it is relatively easy to set a target name within a predetermined frame by predicting from continuous movement of the name, when moving the list with the initials of the Japanese syllabary, Since the movement of the lower target name is discrete, the movement may not be able to be stopped in a timely manner when the target initial is included in a predetermined frame. In other words, the lower names of initials are different from those with many or few, so when moving the list with the initials, after the target initial is entered in the predetermined frame, the scroll button is pressed. Even if it is released, it may move to the next initial letter due to the time lag of the control system. For this reason, it is necessary to return by a scroll button in the reverse direction, and there is a problem that operability is poor.

If the movement of the initials as described above is not discrete but continuous with respect to the list of names, the same operability as the movement of one line can be obtained, but up to the target name. Takes time to move.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide an information display device capable of eliminating over-scrolling during head scrolling.

Draw in the memory not currently displayed (step S1
5) If there is no next initial character, the data before the first data of the current initial character is drawn at the head in a memory that is not currently displayed (step S16), and the display screen is displayed in that memory. The top of the switched and drawn name list is superimposed and displayed on the top frame (step S17), and further scrolled up one line (step S18).

If the feed direction is downward feed, the previous initial is searched from the registered point data (step S19), and it is checked whether or not there is the previous initial (step S20). If there is, the data before the first data of the previous initial character will be the first,
Draw in the memory not currently displayed (step S2
1) If there is no previous initial, the data is drawn in a memory not currently displayed, starting with the data immediately before the head data of the current initial (step S22), and the display screen is displayed in that memory. The second line of the switched and drawn name list is superimposed on the top frame (step S23) and further scrolled down one line (step S24). Here, the processing of steps S15 and S16 and steps S21 and S22 represent scroll control by the first scroll control means, and the processing of steps S18 and S24 represent scroll control by the second scroll control means.

The basic configuration of image data display when displaying spot data names by genre in setting destinations, etc., is to draw a frame in the window image memory (first image memory) as shown in FIG. Then, the initials of the Japanese syllabary and the point data name are drawn in the base image memory (second image memory), and these are superimposed by the image processor and displayed on the display. The image memory 44 is used as the window image memory. On the other hand, when performing the heading display according to the present invention, as shown in FIG. 6, the base image memory is composed of the first memory and the second memory. When the window image memory and the first memory of the base image memory are superimposed by the image processor and displayed on the display, for example, 5
When the zero sound is touched, the next initial character is searched from the registered point data, and a point name list is drawn in the second memory of the base image memory from the data immediately before the next initial character. Upon completion of the drawing, the base image memory is switched from the first memory to the second memory, and the images are superimposed by the image processor, displayed on the display, and then scrolled by one line.
By doing so, as shown in FIG. 6, when starting the next “i” from the initial “a”, first the “i”
Is displayed one line below and then scrolled to the top.

Next, the flow of the operation of registering a memory point will be described with reference to a specific configuration example of a screen. 7 is a diagram showing an example of the overall configuration of the operation unit and the display unit, FIG. 8 is a diagram showing an example of the configuration of a destination setting screen and a menu screen, and FIGS. 9 and 10 are diagrams for explaining an example of a change in head scrolling. FIG.

In FIG. 7, a display 61 is constituted by a color CRT or a color liquid crystal display, and is provided in an instrument panel near a driver's seat by combining a screen with a touch panel. Then, all screens necessary for navigation, such as the current location, a guide screen, a destination setting screen, and a menu screen based on the map data and the guide data processed by the central processing unit 4 are output in color display, and selection and operation of the screen are performed. Buttons for giving instructions are displayed, and a touch panel is provided on the screen to detect selection and operation of these buttons. In addition, the passing intersection information such as the passing intersection name is displayed in color in a pop-up on the section map screen as needed.

Also, the cruising distance calculated based on the remaining gasoline, fuel consumption, and the like is displayed in the cruising range area. "Phonebook" is used to register and provide telephone numbers of facilities such as JAF, road traffic information centers, tourist information centers, emergency medical information centers, restaurants and hotels that often check their telephone numbers, such as destinations. Is what you do.
"CD CRAFT" is selected when a CD-ROM is mounted and its software is used on this display input screen. "Memory point registration" is for registering points that the driver prefers to use, such as golf courses, acquaintances' homes, and various facilities, and includes telephone numbers and addresses, around the current location, around destinations, golf courses, etc. Using the facility name of the facility, etc.
You can register. “Erase memory point” is to delete a point registered by “memory point registration”.
The "change" of the route is for changing to a route passing through a new destination, a passing point, or a detour, and the "deletion" is for deleting a route that has already been searched. And volume adjustment,
This is selected when adjusting the volume of the speaker 16, and “OFF” stops sound output, “Small”,
“Medium” and “high” are operated when decreasing or increasing the volume. “Correction” is for correcting a geomagnetic sensor or the like provided as a means for detecting the current position when it is affected by noise.

On the destination setting screen shown in FIG. 8A, for example, when the "golf course" button of the facility name is touched,
An index screen for the facility name as shown in FIG. 9A is displayed. The index screen includes a data display unit 101 for displaying index data for a golf course, and "previous" and "next" buttons for scrolling when the information displayed on the display unit is not the desired information. It comprises a scroll button 102 for moving forward one line and a scroll button 103 for heading "50 sounds" which is a movement instruction means in the present invention. The information displayed on the display unit is arranged in the order of the Japanese syllabary.
The initial of the sound is attached. When the touch of the scroll button 103 for the heading of the "50 sounds" is detected, the "before" of the first letter currently displayed on the display section is displayed.
Alternatively, a search is made for the initial letter of the Japanese syllabary with the initial letter corresponding to “next”, and the scrolling is performed so that the initial letter becomes the top of the display section. That is, for example, FIG.
In the state of (a), when the scroll button 103 for the heading of "50 sounds" is touched once, the head of the "i" line is displayed at the head position of the display unit as shown in FIG. Scroll control. Furthermore, in the case where the scroll button 103 for the heading of "50 sounds" is kept pressed,
While the button is kept pressed, the beginning of each line is repeated in the order of the Japanese syllabary (or in the opposite direction), that is, the beginning of each line is stopped at the head position of the display unit for a predetermined time and then the head of the next line is displayed at the head position. Scroll button 10 for "50 sounds"
If it is detected that the line has been released from the position 3, if the scrolling process is being performed at that point, the head of the next line to be displayed is displayed at the head position of the display unit. When the head of the line is stopped at the head position of the display unit for a predetermined time, "50
When the sound is released from the scroll button 103 for the heading of the sound, the display at that time remains as it is. Here, when the "next" key in the "next" direction is pressed, the "50" key in the forward direction is pressed. The head scroll is executed.

In order to display the first letter of the Japanese syllabary at the head position of the display unit, scroll control is performed so that the initial letter of the Japanese syllabary moves to a position one line before the head position of the display unit. Is controlled to scroll from the position to the top position of the display unit. In other words, the description will be made with reference to the drawing. In the state of FIG.
As shown in FIG. 10B, the head of the “i” line is moved one line before (the second position) from the head position of the display frame displayed on the display unit, and thereafter, as shown in FIG. Scroll to the beginning of. Also, when the scroll button 103 for the heading of "50 sounds" is kept pressed, such processing is repeated to perform display control.

In this case, data is read from the window image memory shown in FIG. 6, ie, the first image memory in which data representing the display frame is stored, and the display frame displayed on the display unit as shown in FIG. Performs drawing control in a state where it is fixed, and draws data read from the base image memory, that is, the second image memory in which information data is stored, by rewriting the information displayed on the display unit according to scrolling and drawing. . Then, as shown in FIG. 10 (b), it moves so as to dive under the frame. For this reason, it is possible to make it easy to see the moving direction of the character at the time of scrolling, and it is possible to make head scrolling easy to use. In particular, in the case where the line to be displayed is moved to the head position of the list by pressing and holding the scroll button to select the line, the above-mentioned configuration is adopted, and the head of each line is headed in the order of the Japanese syllabary.
In addition to being able to select quickly, the moving direction of the scroll is easy to recognize. In particular, when used for vehicles, a display device with excellent visual effects is required, and in the conventional device, the display is moved instantaneously when heading, and the scroll direction cannot be understood during scrolling. However, the configuration as in the present embodiment makes it easy to recognize the direction in which scrolling flows, to easily predict the next line to be displayed, and to prevent over-scrolling.

It should be noted that the present invention is not limited to the above embodiment, and various modifications are possible. For example, in the above embodiment, the original position is the top row, but the center position may be the original position. Further, an example in which the genre of the golf course is specified in the destination setting has been described. However, it is needless to say that the present invention can be similarly applied to other facilities and addresses, and can be similarly applied to memory point registration. Further, in the present embodiment, the genre-based point data is arranged in the order of the Japanese syllabary. However, the genre-based point data may be arranged in the order of the Japanese syllabary. The display may be rearranged when displaying. This makes it easy to add or change data. Further, in the above embodiment, the touch switch is used as the input unit for performing the scroll instruction and the selection instruction. However, the input unit is not particularly limited, and an input unit using a remote controller or a keyboard may be used.

As is apparent from the above description, according to the present invention, the initials in the order of the Japanese syllabary and the point data names thereunder are displayed side by side in a frame extending over a plurality of lines, and displayed on the display unit. When the head scroll and the one-row scroll button are used to perform the respective movements for performing the change setting, and when the head scroll is performed by the instruction of the movement instructing means, the original position (first predetermined position) is set. First, the initial line is displayed one line before (the second predetermined position) with respect to the scroll feed direction, and then one line is scrolled to the original position, so that prediction is easy and over-scrolling can be prevented. . Further, since the initials and the point data names are moved so as to pass under the frame with the frame fixed, it is possible to easily see the moving direction of the character at the time of scrolling.
