Description

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 vehicular navigation device having a function of inputting a destination such as a destination or a passing point.

[0002]

2. Description of the Related Art In a vehicular navigation device mounted on an automobile or the like, when inputting an arbitrary point and setting a destination or a passing point, an input form of the point is input by a code number or input by map coordinates, Inputting registration points by searching by genre, inputting by telephone number, etc. are used. Among them, for example, addresses, stations, government offices, intersections, airports,
When inputting registration points by searching by genre such as port, police station, parking lot, hospital, etc., when a genre is first selected, the names belonging to that genre are displayed in a tree structure in descending order according to each selection. To do. In this case, names to be selected are displayed in a list in the order of Japanese syllabary over a plurality of lines, and the names are selected with a predetermined position in the list as a selection frame.

FIG. 11 is a diagram showing a display example of scrolling a list in a conventional selection frame. A navigation device having a point registration function has been proposed in Japanese Patent Laid-Open No. 5-313573. This is because when a point such as a destination or a passing point is input, the input point is registered in the system. The next time, the registration point will be used to facilitate the input operation. The example shown in FIG.
This is an example of a case where such point registration is performed by inputting, for example, an address. Although not shown in the figure, when an address is selected on the place name index screen for point registration, prefectures and major cities are displayed in the selection frame in the order of Japanese syllabary, and when the 23 wards of Tokyo are selected, Sumida Ward is moved to the position of the selection frame and displayed. "Shi", "su",
The letters “se” and “ta” are initials, the arrow on the left side is the heading scroll button, and the arrow on the right side is the line feed scroll button. When the heading scroll button is touched, the initials are “Shinjuku Ward”. , “Suginami Ward”, ..., And so on, the list is moved to the top row, for example, and when the line feed scroll button is touched, the list is moved line by line.

[0004]

In the screen in which names and the like are displayed in the selection frame in the order of the Japanese syllabary as described above, when moving (scrolling) line by line 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 names, when moving a list by the initials of the Japanese syllabary, the Since the movement of the target name of the lower order becomes discrete, it may not be possible to stop the movement in good timing when the initial letter of the target is included in the predetermined frame. In other words, the names of the subordinates of the initial letters are different from those with more and less, so if you move the list with the initials, the scroll button is pressed after the target initials are entered in the specified frame. Even if they are separated, the next initial may be moved due to the time lag of the control system. Therefore, it is necessary to return the scroll button in the opposite direction, which causes a problem of poor operability.

If the movement of the initial letters as described above is continuous rather than discrete with respect to the list of names, the operability equivalent to moving one line at a time can be obtained. It takes time to move.

The present invention has been made to solve the above problem, and an object of the present invention is to provide an information display device capable of eliminating overscrolling in the head scroll.

[0007]

To this end, the present invention provides a storage device for storing various information, a display unit for displaying various information stored in the storage device, and information displayed on the display unit.

In addition, the travelable distance calculated based on the remaining amount of gasoline, fuel consumption, etc. is displayed in the range of cruising distance. The "phone book" is provided by registering the telephone numbers of facilities such as JAF, road traffic information center, tourist information center, emergency medical information center, restaurant / hotel, etc. where the telephone number is often checked such as destination. To do.
"CD CRAFT" is selected when the CD-ROM is mounted and the software is used on this display input screen. "Memory location registration" is for registering locations that the driver prefers to use, such as golf courses, acquaintances' homes, various facilities, etc., such as telephone numbers, addresses, present locations, destinations, golf courses, etc. Select using the facility name such as
You can register. "Memory location deletion" is to erase the location registered in "memory location registration".
The "change" of the route is to change to a route passing through a new destination, a passing point, or a detour, and the "delete" is to delete the route that has already been searched. And volume adjustment,
This is selected when the volume of the speaker 16 is adjusted, and “OFF” stops the audio output, “small”, and
"Middle" and "high" are operated to reduce or increase the volume. The “correction” is for correcting the geomagnetic sensor or the like equipped as a means for detecting the current position when the influence of noise.

In the destination setting screen of FIG. 8A, for example, when the "golf course" button of the facility name is touched,
An index screen of facility names as shown in FIG. 9A is displayed. This index screen includes a data display unit 101 that displays index data for the golf course, and "Previous" and "Next" buttons for scrolling when the information displayed on the display unit is not the desired information. It is composed of a scroll button 102 for line feed and a scroll button 103 for cueing "50 sounds" which is a movement instructing means in the present invention. The information displayed on this display unit is arranged in the order of Japanese syllabary, with 50 at the beginning of each Japanese syllabary.
The initials of the sound are attached. When the touch of the scrolling button 103 for heading the "Japanese syllabary" is detected, "front" of the first initial letter currently displayed on the display unit is detected.
Alternatively, an initial letter corresponding to "next" is searched for with the attached initial letter of the Japanese syllabary, and the scrolling control is performed so that the initial letter becomes the head of the display unit. That is, for example, in FIG.
In the state of (a), when the "50s" cueing scroll button 103 is touched once, the beginning of the "i" line is displayed at the beginning position of the display section as shown in FIG. 10 (b). The scroll is controlled. In addition, if you continue to press the scroll button 103 for heading the "Japanese syllabary",
While the button is held down, the head scrolling of each line is repeated in the order of the Japanese syllabary (or in the reverse direction), that is, the head of each line is displayed at the head position of the display unit and after the predetermined time is stopped, the head of the next line is displayed at the head position. "50 syllabary" scroll buttons for heading 10
When it is detected that the line is separated from 3, if the scroll processing is being performed at the time of the separation, the head of the line to be displayed next is displayed at the head position of the display unit. Also, when the head of the line is stopped at the head position of the display for a predetermined time, "50
If it is released from the “sound” heading scroll button 103, the display at that point remains. If the "50" key in the "next" direction is pressed, it will be in the forward direction of the 50 sounds, while if the "50 sounds" key in the "forward" direction is pressed, it will be in the reverse direction of the 50 sounds. Head scrolling is executed.

In order to display the initials of the Japanese syllabary at the start position of the display unit, first, scroll control is performed so that the initials of the Japanese syllabary moves to the position one line before the start position of the display unit. It is controlled to scroll from that position to the top position of the display unit. That is, to explain with reference to the drawing, when the upper feed button of the “50 syllabary” head start scroll button 103 is pressed once in the state of FIG.
As shown in (b), the head of the "i" line is moved to the position one line before (the second position) from the head position of the display frame displayed on the display unit, and then the display frame is displayed as shown in FIG. 10 (b). Scroll to the beginning position of. Further, even when the scroll button 103 for "heading" of the "50" is kept pressed, such a process is repeated to perform the display control.

In this case, the data is read from the window image memory shown in FIG. 6, that is, the first image memory in which the data representing the display frame is stored, and the display frame displayed on the display section as shown in FIG. Performs drawing control in a fixed state, and rewrites the data read from the base image memory, that is, the second image memory in which the information data is stored, by rewriting the information displayed on the display unit according to the scroll. . Then, as shown in FIG. 10B, 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 when scrolling, and it is possible to make head scrolling easy to use. In particular, when the line to be displayed is moved to the beginning position of the list to be selected by continuously pressing the scroll button, the above-mentioned configuration is adopted. Therefore, by beginning the beginning of each line in the order of the Japanese syllabary,
In addition to being able to select quickly, the moving direction of the scroll can be easily recognized. Especially when used for vehicles, a display device with excellent visual effect is required, and in the conventional device, the display is momentarily moved when the head is crammed, and the scroll direction cannot be understood during scrolling. However, by configuring as in the present embodiment, the direction in which the scroll flows can be easily recognized, the line to be displayed next can be easily predicted, and overscroll can be prevented.

The present invention is not limited to the above embodiment, but various modifications can be made. For example, in the above embodiment, the original position is the top row, but the central position may be the original position. Further, although an example in which the genre of the golf course is designated in the destination setting is shown, it is needless to say that the same can be applied to other facilities and addresses, and the same can be applied to memory point registration. Further, in the present embodiment, the genre-specific spot data is arranged in the order of Japanese syllabary. However, the genre-specific spot data may be arranged in advance in the order of Japanese syllabary and stored. You may make it rearrange when displaying from. This makes it easy to add or change data. Further, in the above-described embodiment, the touch switch is used as the input unit for issuing the scroll instruction or the selection instruction, but the input unit is not particularly limited, and an input unit such as 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 below the initials are displayed side by side in a frame extending over a plurality of lines, and the displayed information is displayed. When the head scrolling scroll button and the line feed scrolling button are used to perform the change setting, when the head scrolling is performed by the instruction of the movement instructing unit when the respective movements are performed, the original position (first predetermined position) is set. The first letter 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, which facilitates prediction and prevents overscrolling. . Since the frame is fixed and the initial letter and the point data name are moved so as to pass under the frame, it is possible to easily see the moving direction of the character when scrolling.
