Embodiment Construction

[0031] Hereinafter, an embodiment of the present invention will be described in accordance with Figure 1 to Figure 6 Be explained. figure 1 It is a front view of a navigation device (hereinafter, simply referred to as a navigation device) as a display device of the present embodiment.

[0032] Such as figure 1As shown, the navigation device 1 includes a display 3 as a display means fixed to the housing 2 . Furthermore, the navigation device 1 is provided with each switch 4 and the operation part 5 which is arrange|positioned rotatably with respect to the housing|casing 2 as an input means. Each switch 4 is an input unit for selecting each mode, inputting current location / destination, volume adjustment, etc., and the operation unit 5 is an input unit for scrolling the map screen 100 displayed on the display 3 .

[0033] For example, if figure 1 As shown, when wanting to display the right side of the map screen 100 as an image on the display 3, to figure 1 Rotate the opera...

Abstract

Provided are a navigation device, a display switching method, and a display device capable of improving operability when performing continuous scrolling display. A navigation device (1) includes a display (3), an operation unit (5) for rotating the operation unit (5), and a control unit (10) for detecting the rotation amount and the rotation direction of the operation unit (5). The control unit (10) calculates the displacement of the map drawing data corresponding to the rotation amount and rotation direction of the operation unit (5), determines a display area of ​​the map drawing data based on the displacement, and outputs the display area to the display. In addition, when the control unit (10) detects that the operation unit (5) has rotated more than a first rotation amount in one direction within a predetermined period of time, it continuously shifts the display area of ​​the map drawing data and displays it on the display (3). Scrolls the display continuously.

Description

technical field [0001] The invention relates to a navigation device, a display switching method and a display device. Background technique [0002] In conventional navigation devices, a map screen can be scrolled and displayed on a display by operating an input unit such as a switch or a rotatable dial. For example, the navigation device described in Patent Document 1 performs switching between the scroll display mode and the normal mode, determination of the scroll direction, and the like based on the pressing operation of the rotary switch, the rotation direction, and the like. [0003] However, in the navigation device as described above, when scrolling the screen, it is necessary to continuously operate the input unit until reaching a desired position. For example, in the case of a navigation device equipped with a dial, it is necessary to continuously rotate the operating dial until the user's desired position is displayed on the display, so there is a problem in opera...
