ABSTRACT:
An apparatus for superimposing a display image of vehicle data or position data of the vehicle on video signals of the surroundings of the vehicle. An object picked up is converted into video signals by an image pick-up camera having an image pick-up drive circuit, an amplifier circuit, a wave shaping circuit, a non-linear amplifier circuit, and a diaphragm control circuit. The video signals are gamma corrected in the non-linear amplifier circuit. Superimposed video signals are read from a memory of stored characters, figures or the like and synchronizing signals are mixed into composite video signals. The composite video signals are superimposed with pattern signals, graphic signals, character signals or the like and displayed by using a liquid crystal or a CRT.
