Provided are a navigation device, a control method for the navigation device, and a control program for the navigation device, the navigation device having a configuration in which a guide image is displayed at a location corresponding to a guide point of a displayable region and the size of the guide image can be changed in accordance with the distance to the guide point, the situation that a guide image can be displayed or cannot be displayed at a far guide place is effectively avoided, and the guide place and the guide image can be correctly recognized. A navigation device (1) that executes navigation processing in a vehicle is provided with: an image display unit (2) that displays a processed image to be provided for navigation in a space ahead of a driver so that the driver can see a scene ahead; and a display control unit (3) that controls the display of the image display unit (2). When the distance to the guide point (P) is equal to or less than the first display switching determination distance, the guide image (G) is displayed at a predetermined magnification at a location corresponding to a predetermined distance in front of the vehicle while the distance to the guide point (P) exceeds the second display switching determination distance, and when the distance to the guide point (P) is equal to or less than the second display switching determination distance, the guide image (G) is displayed at a predetermined magnification at a location corresponding to a predetermined distance in front of the vehicle. The guide image (G) is gradually enlarged at a magnification corresponding to the distance to the guide point (P), and is displayed at a location corresponding to the guide point (P).
本发明提供一种导航装置、导航装置的控制方法、导航装置的控制程序,所述导航装置,在与可显示区域的引导地点对应的部位显示引导图像,并根据到引导地点的距离而能够改变引导图像的大小的结构中,有效地避免在远处的引导地点能够显示引导图像或不能够显示引导图像的状况,能够正确地识别引导地点、引导图像。在车辆中执行导航的处理的导航装置(1)中,具备:图像显示部(2),所述图像显示部(2)在驾驶员的前方空间显示提供给导航的处理的图像,使得驾驶员能够视觉辨认前方风景;以及显示控制部(3),所述显示控制部(3)控制图像显示部(2)的显示。在到引导地点(P)的距离为第一显示切换判定距离以下时,在到引导地点(P)的距离超过第二显示切换判定距离的期间,在与车辆的前方的一定距离对应的部位以一定的倍率显示引导图像(G),在到引导地点(P)的距离为第二显示切换判定距离以下时,以与到引导地点(P)的距离对应的倍率逐渐扩大引导图像(G),在与引导地点(P)对应的部位进行显示。
