Abstract: In a display system, a HUD displays a virtual marker D indicating a vehicle shape which guides a traveling direction of a user's vehicle. The display system measures an inter-vehicle distance between the user's vehicle and a forward vehicle and determines a display position and a display size of the virtual marker in accordance with the inter-vehicle distance. The virtual marker is shifted to a near side of the user's vehicle when the inter-vehicle distance is small, whereas the virtual marker is shifted to a far side of the user's vehicle when the inter-vehicle distance is large. A portion of the virtual marker is brought into a non-display state as if the portion is absorbed into the user's vehicle when the inter-vehicle distance is reduced, and the virtual marker is not displayed when the distance is further reduced.

Abstract: A 3D object detecting device includes a driving-lane detecting unit that detects a driving lane of a vehicle; a 3D-object detecting unit that detects, by using pattern recognition technology, a type of 3D object with respect to images captured by side cameras; and a recognition-priority setting unit that varies and sets a recognition priority for the detected type of 3D object, based on the detected driving lane. In accordance with the driving lane of the vehicle, the recognition-priority setting unit sets the priority for pattern recognition lower for a type of 3D object that is less likely to exist in rear left and right sides of the vehicle, to thereby reduce the possibility that a 3D object that should not be regarded as a warning target is erroneously detected from the images as a warning subject.
