ABSTRACT:
A display device of the present invention is mounted on an automotive vehicle. An obstacle located in front of the vehicle is detected by a camera, and its features including speed, distance, size, etc. are analyzed by electronic circuits. An image showing the features of the front object is outputted from a liquid crystal panel. The outputted image is reflected on the windshield, displaying a virtual image to a driver. The virtual image is displayed in a form of a spot encircling the front obstacle seen through the windshield. The ways of displaying the encircling spot are variously changed according to a degree of collision danger that is determined according to a period in which the vehicle reaches the obstacle. For example, if the degree of collision danger is high, the spot is shown in red-orange color and/or with a high brightness. Thus, the driver easily recognizes the front obstacle in a high degree of collision danger.
