In an apparatus for controllably supplying visual information for a viewer, an optical system including ocular glasses corresponding to right and left eyes of the driver (viewer) is provided so that images on a pair of liquid crystal televisions are introduced to the pair of ocular glasses to provide a three-dimensional solid image. Two television cameras are installed on a vehicle so as to be faced in the rearward direction with their bodies juxtaposed to each other. When the vehicle is reversed, a reflectivity of a half mirror is maximized so that a rearward scenery can be viewed via the ocular glasses in the form of a solid image. During the forwarding of the vehicle, a forward field of view is produced for a half mirror with a transmissivity of the half mirror maximized.
