More specifically, the map scroll direction is determined in the direction in which the joystick 100 is operated (the direction in which the stick is tilted), and the map is continuously scrolled by continuing to operate the joystick 100 (in the stick tilted).

FIG. 2A shows that the joystick 100 is
FIG. 2B shows a state in which the map 111 has been scrolled upward on the scroll screen 110a. In this figure, 1
Reference numeral 12 indicates a cross cursor.

[0005] The map scrolling operation is stopped by ending the joystick operation (the state in FIG. 1 in which the stick is in the neutral position).

[0006]

However, when the map is scrolled with the joystick 100 to determine the up, down, left, and right diagonal directions in the conventional method, the ambiguity in the up, down, left, right diagonal directions in the structure of the device may cause a problem in determining the direction. Can be difficult.

For example, in the case of the eight-way joystick 100 shown in FIG. 1A, from point A to point B shown in FIG.
When scrolling the map along the road 133, the upper right (operation 131), the upper right (operation 132), the upper right, the upper right,.
Operation must be repeated. Such a complicated operation is caused by a structural limitation of the joystick 1.

For example, in the case of an eight-way joystick 100 as shown in FIG. 1A, even if the user tilts the joystick 100 in a direction that makes a road,
Since the selectable scroll direction of the joystick 100 is finite (eight directions in this example),
It may be right or up.

That is, the direction desired by the user to select may not match the scroll direction determined on the joystick device side.

[0010] By increasing the selectable scroll direction with the joystick 100, it is possible to select a direction more suitable for the user to some extent. However, due to the structure and operability of a joystick device, the selectable scroll direction is increased. There is a limit to the number of directions. The actual number of scroll directions in a conventional joystick is considered to be about eight directions at the maximum.

An object of the present invention is to provide a scrolling method capable of performing scrolling in a target direction with higher precision.

Another object of the present invention is to provide a navigation device that realizes map scrolling that can perform map scrolling in a target direction with higher accuracy.

[0013]

In order to achieve the above object, the present invention relates to a scrolling method for receiving a user's operation input and changing a display image area to be displayed on a display device. Operation input, and an operation input for the input moving amount in the scroll direction, which is performed independently of the input of the scroll direction, is received, and according to the received scroll direction and the moving amount, It is characterized in that the display image area is changed.

According to another aspect of the present invention, there is provided a navigation apparatus for displaying a map on a display device to perform a navigation operation of a vehicle. And input means for receiving an operation input for the input movement amount in the scroll direction, which is performed independently of the input of the scroll direction. Scroll processing means for changing a map area to be displayed on the display device.

Here, the input means is constituted by a turn knob, and the scroll processing means sets the scroll direction in accordance with a rotation operation performed on the turn knob, and controls a pressing operation performed on the turn knob. It is preferable that the moving amount is set according to the duration.

The scroll processing means may set a plurality of selectable scroll directions in advance, and select one of the plurality of scroll directions according to the amount of rotation of the turn knob.

Further, in the navigation apparatus according to the present invention, there is further provided a scale input means for receiving the setting of the scale of the display map, wherein the scroll processing means is adapted to select a preset setting in accordance with the scale of the received display map. It is good also as a structure which determines the number of possible scroll directions.

The configuration of the present embodiment is basically the same as the configuration of the above-described embodiment, and only different points from the above-described embodiment will be described below.

FIG. 1 shows the map scrolling process of this embodiment.
1 will be described.

In this processing, the scale of the map currently displayed (to be scrolled) is detected (step 1001).
The number of map scroll directions that can be selected is set according to the detected map scale (step 1002).

For example, as shown in FIG. 12 (b), when the map scale is wide, it is not necessary to scroll in a fine direction, so that an 8-direction scroll is displayed, and as shown in FIG. 13 (b), the map scale is detailed. In the case of, fine scrolling is necessary, so that the display in 16 directions or stepless scrolling is performed.

In order to set the number of scroll directions corresponding to the map scale, correspondence table data in which the scale 1401 and the number of scroll directions 1402 are made to correspond to each other as shown in FIG. The number of scroll directions is set based on the scale of the selected map by referring to the correspondence table data as needed.

The correspondence table data shown in FIG. 14 is an example, and the number of selectable scroll directions may be set using another method. Further, it is sufficient that a smaller number of scroll directions is set at a larger scale (larger scale), and the specific number of scrolls is not limited to the number in this example.

In the scroll processing of the present embodiment, the scroll processing as shown in FIG. 7 is further executed (step 1003), and the above-described steps are performed only when the scale of the map is changed (step 1004). 10
Returning to 01, the number of selectable scroll directions is reset.

In the scroll processing of step 1003,
For example, when the scroll direction of the map is selected by the left / right operation of the turn knob, while the turn knob PUSH is operated,
The map is scrolled in the selected map scroll direction. Further, when the push operation of the turn knob is stopped, the map scrolling is stopped, and the screen is changed to a screen in which the scroll direction of the map can be selected again.

According to the present embodiment, by making the scroll direction variable according to the scale, a wide area map can be roughly searched for by scrolling, and the operation is easy because the number of scroll direction selections is small. .

That is, in a detailed map, since a map is often searched by following a fine alley and searching for a point, the number of directions of scrolling is larger than that in a wide area map, and scrolling is performed in a direction more suited to the user's consciousness. Can do things.

Further, according to the present embodiment, the number of scroll directions that can be selected is set according to the map scale, so that an optimum number of map scroll directions can be provided for each map scale.

In the above two embodiments, the map scroll in the navigation device has been described.
The invention is not limited to scrolling the map,
Various display means for scrolling in a target direction can be applied in the same manner as in the above embodiment.

[0054]

According to the present invention, in the scroll method and the navigation apparatus, the map scroll direction is reliably determined by performing the map scroll by operating the turn knob, and the scroll in the target direction is performed with higher precision. It becomes possible.

Further, according to the present invention, since the operation of determining the scroll direction and the operation of starting the scroll operation are independent, the scroll direction can be confirmed and selected on the screen in advance, and the user can meet the user's wishes. Thus, there is an effect that a finer direction can be selected. Therefore, it is possible to provide a navigation device that easily realizes a map scroll operation in multiple directions and realizes a map scroll that enables a map scroll in a target direction with higher accuracy.
