Abstract
A vehicle display system recognizes, from within a color image of a forward scenery of a subject vehicle, an object such as left and right brake lights of a leading vehicle or a halt sign, each of which includes a red light element. Of the recognized object, a given position on a display area in a windshield of the subject vehicle is extracted. The extracted given position is then highlighted on the display area so that a user of the subject vehicle can properly recognize the object including the red light element.
