Problems solved by technology

[0009] However, the configuration of Patent Document 2 does not require manual change of the scale when the own ship deviates from the course, but for example, when referring to a detailed chart near the own ship, it is necessary to manually enlarge the scale
In addition, when the scale is enlarged, it is not possible to refer to the route that has been set, or to refer to a port that is far from the own ship, etc.
Therefore, even with the configuration of Patent Document 2, there are cases where the scale must be frequently changed.

Embodiment Construction

[0052] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a block diagram of the radar apparatus 1 for ships which concerns on one Embodiment of this invention. Figure 2A and Figure 2B It is a diagram showing an example of a screen displayed on the display unit 35 .

[0053] Such as figure 1 As shown, the marine radar device 1 of this embodiment includes a radar antenna 11 and a radar indicator (information display device) 12 .

[0054] The marine radar device 1 is configured as a pulse radar device, and the radar antenna 11 is configured to transmit highly directional pulsed radio waves and receive reflected waves (echoes) of the pulsed radio waves reflected by objects. In addition, the radar antenna 11 is configured to repeatedly transmit and receive radio waves while rotating in the horizontal plane. With the configuration described above, it is possible to perform scanning (scan) in all directions (360°)...

Abstract

An information display device (12) includes a display unit (35) for displaying, on a display screen, a first range (71) and a second range (72) having a display reference position same as that of the first range (71) and being adjacent to the first range (71) in a display area (70). The device also includes a controller (34) for setting different scales for the first range (71) and the second range (72) and for performing a control to display perimeter information of the device in the display area (70) having the first and second ranges (71, 72) to correspond to a position of the perimeter information.

Description

technical field [0001] The invention mainly relates to an information display device with two display areas. Background technique [0002] Conventionally, a radar device for ships as disclosed in Patent Document 1 has been known to display images (radar images) showing objects around the ship and to change the scale of the radar images. If the scale is enlarged, only a narrow range of radar images near the own ship can be displayed, but the detailed position and shape of the echo representing the object can be grasped. On the other hand, if the scale is reduced, a wide-range radar image can be displayed, but it is difficult to judge the position and shape of the echo in detail. [0003] Therefore, in the marine radar device configured as described above, it is necessary to change the scale according to the situation. This is not limited to radar devices for ships, and the same applies to radar devices installed on the ground, navigation devices for vehicles, and the like. ...
