えた車両用映像重畳表示装置。a first video signal generating means for generating a first video signal;
a second video signal generating means for generating a video signal; and a second video signal generating means for generating a video signal;
The first of the video signal generation means or the second video signal generation means
- a video signal mixing means connected to the first and second video signal generating means for passing or mixing the second video signal; and a video signal mixing means for receiving the output signal of the video signal mixing means. In a video display device comprising a display means connected to an output section, a first synchronization signal generated by the first video signal generation means causes the output to perform a first inversion, and a second video signal generation means generates the output. A latch circuit configured to cause the output to undergo a second inversion effect in response to a second periodic signal having a period longer than the first synchronization signal by a predetermined period; and a latch circuit that generates the first periodic signal between the first inversion effect and the second inversion effect. 1. A video superimposition display device for a vehicle, comprising a synchronous mixing means whose output part is connected to the first video signal generation means to temporarily stop the operation of the synchronization circuit of the first video signal generation means.
