Abstract:
1. An image display system for use of a driver in a subject vehicle comprising: a look area detector for detecting a look area of the driver who watches a real leading vehicle through a transparent glass in front of the driver; a control unit for controlling a display of a transparent image on the transparent glass in front of the driver for representing a virtual leading vehicle; a position detector for detecting a current position of the subject vehicle; and a hot spot storage unit for storing information on a hot spot which the driver of the subject vehicle pays attention to; wherein when the look area detected by the look area detector overlaps at least a portion of the transparent image of the virtual leading vehicle displayed on the transparent glass, the control unit increases a degree of transparency of at least an overlapping portion of the transparent image of the virtual leading vehicle relative to a non-overlapping portion of the transparent image of the virtual leading vehicle; and the control unit begins control of the display of the transparent image of the virtual leading vehicle when a distance between the current position of the subject vehicle detected by the position detector and the hot spot stored in the hot spot storage unit becomes smaller than a first preset value; wherein an intensity of the real leading vehicle is not varied.
