    摘要： There is provided an on-vehicle stereoscopic display device wherein the same graphics having different brightness levels are superimposed on display devices to represent the depth of a graphic. The device has a configuration such that information indicating a cross-sectional shape of a graphic to be stereoscopically displayed is generated, and based on the generated information indicating the cross-sectional shape, the graphic having the depth is transparently displayed from the front to the rear of the screen. It is, therefore, possible to provide the on-vehicle stereoscopic display device wherein levels of the depth of a graphic to be stereoscopically displayed do not depend on the number of display devices, there are fewer limitations over a position of an operator to watch the display, and the superior visibility is provided.
