An on-vehicle system mountable in a vehicle, the system comprising: a head-up display configured to display a picture as a virtual image at a position ahead of a front window of the vehicle; and a control unit that is configured to display a route guide image on the head-up display during a period in which the vehicle is stopping in response to a stop command signal from a traffic light; characterized in that the control unit has an image creating and displaying unit that is configured to create an image of a scene viewed from a virtual point of view in a virtual line-of-sight direction and to display the created image on the head-up display as the route guide image, and a to-be-viewed target changing unit that is configured to gradually change a combination of the virtual point of view and the virtual line-of-sight direction for an image to be created by the image creating and displaying unit by using a point at which the vehicle is predicted to arrive as a guide point, from a first combination in which the same position as the point of view of the user of the vehicle is used as the virtual point of view and a forward direction of the vehicle is used as the virtual line-of-sight direction to a second combination for taking a bird's eye view of a geographic range that includes at least part of a geographic range between a current position of the vehicle and the guide point and then from the second combination to a third combination for taking a bird's eye view of a geographic range that includes the guide point, wherein a position of the virtual point of view in the second combination is closer to the current position than a position of the virtual point of view in the third combination is, and the position of the virtual point of view in the third combination is closer to the guide point than the position of the virtual point of view in the second combination is. a head-up display configured to display a picture as a virtual image at a position ahead of a front window of the vehicle; and a control unit that is configured to display a route guide image on the head-up display during a period in which the vehicle is stopping in response to a stop command signal from a traffic light; characterized in that the control unit has an image creating and displaying unit that is configured to create an image of a scene viewed from a virtual point of view in a virtual line-of-sight direction and to display the created image on the head-up display as the route guide image, and a to-be-viewed target changing unit that is configured to gradually change a combination of the virtual point of view and the virtual line-of-sight direction for an image to be created by the image creating and displaying unit by using a point at which the vehicle is predicted to arrive as a guide point, from a first combination in which the same position as the point of view of the user of the vehicle is used as the virtual point of view and a forward direction of the vehicle is used as the virtual line-of-sight direction to a second combination for taking a bird's eye view of a geographic range that includes at least part of a geographic range between a current position of the vehicle and the guide point and then from the second combination to a third combination for taking a bird's eye view of a geographic range that includes the guide point, wherein a position of the virtual point of view in the second combination is closer to the current position than a position of the virtual point of view in the third combination is, and the position of the virtual point of view in the third combination is closer to the guide point than the position of the virtual point of view in the second combination is.
