Abstract: Implementations of an in-vehicle display system may include: a first display device configured to irradiate a first area of a windshield of a vehicle with a first light constituting a first image and to display the first image as a virtual image of the first image in front of the first area; a second display device configured to display a second image as a real image in a second area of the windshield that is wider than the first area; and a control device configured to control the first display device and the second display device based on a travel state of the vehicle.

Abstract: A guidance system includes an SNS server that distributes guidance information, e.g., to a smartphone. The SNS server includes a post information DB, a map DB, and a guidance information DB. Pieces of post information and selected guidance information are transmitted to the smartphone via a communication unit. The smartphone displays the pieces of post information, and includes a setting unit that sets, as a destination, a location contained in a piece of post information among the displayed pieces of post information, and a guidance unit that provides, by using the guidance information, guidance on a guidance route to the destination.

Abstract: A vehicle travel amount estimation device includes a camera, a taken image storing unit, a compensated image storing unit, a travel amount calculation unit, a vehicle speed and gyro sensor, and a travel amount determination unit. The taken image storing unit and the compensated image storing unit store images taken by the camera. The travel amount calculation unit calculates the amount of travel based on two stored images. The sensors detect the amount of travel of the vehicle. The travel amount determination unit is configured to compare a first amount of travel calculated by the travel amount calculation unit with a second amount of travel detected by the vehicle speed sensor or the like in order to determine the first amount of travel to be the amount of travel of the vehicle when the difference between the first amount and the second amount is smaller than a predetermined value.
