Apparatus for superimposing a display of detected data for a vehicle
First Claim
1. A vehicle display apparatus comprising :
- an image pickup means for converting an object picked up into an output of video signals;
a diaphragm control circuit for controlling the diaphragm of the image pickup means corresponding to the video output state of the image pickup means;
diaphragm drive circuit and a diaphragm opening setting means for adjusting the diaphragm opening corresponding to the output of the diaphragm control circuit;
a non-linear amplifier circuit for performing gamma correction of the output of the image pickup means after amplifying and wave shaping;
an image memory circuit for providing an output of video signals of a superimposed object stored in a memory;
a control signal generating circuit for generating scanning signals of the image pickup means, scanning signals of the image memory circuit, and synchronizing signals superposed on the outputs of the non-linear amplifier circuit and the image memory circuit;
a mixing circuit for superposing the outputs of the image memory circuit and synchronizing signals of the control signal generating circuit on the outputs of the non-linear amplifier circuit into composite video signals; and
a display means for displaying the composite video signals transmitted from the mixing circuit.

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.
