PROBLEM TO BE SOLVED: To provide a technology for easily adapting a driver to a field of view in a displayed picked-up image when displaying the image imaged by a roadside camera on an on-vehicle device. SOLUTION: A display start point P1, a field angle change point P2, a viewpoint/line of sight direction change point P3 and a relative camera viewpoint position are calculated on the basis of imaging specification information received from a roadside device. When one's own vehicle arrives at the P3, viewpoint position/line of sight direction of the currently displayed navigation image is changed to a viewpoint position of the relative camera and a line of sight direction same as that of the roadside camera. When the own vehicle arrives at the P2, the field angle of the currently displayed navigation image is changed to a field angle same as that of the roadside camera. When the own vehicle arrives at the P1, a navigation image obtained by changing the currently displayed viewpoint/line of sight direction/field angle is switched to a roadside camera image based on the image data received from the roadside device to support driving.
