うにしてもよい。Note that in the embodiment described above, the synchronization signal is separated from the composite video signal a output from the imaging device 5 and is provided to the video projector 2, but the present invention is not limited to this.
Projection video signal C input to video projector 2
It is also possible to separate the synchronization signal and give it to the imaging device 5.

２とに分配する方式を用いることもできる。Further, in the above method, the synchronization signal is separated from the video signal and taken out. For example, as shown in the second leap, the synchronization signal generator f6 generates the synchronization signal d, and the distribution amplifier IF7 generates the synchronization signal d, which is then sent to the imaging device 5. It is also possible to use a method of distributing the information to the video projector 2 and the video projector 2.

C
Since the synchronization is based on d or d, a faithful image can be obtained without stripes occurring in the captured image.
