Document Type and Number:
Japanese Patent JP2000115603
Kind Code:
A
Abstract:
To automatically correct vertical inversion of projected video images in the case of switching the image pickup direction of a video camera part.
A detection switch 31 detects that the image-pickup direction of the video camera part 14 is switched and supplies the detection signal c1 of the detected result to a liquid crystal panel drive circuit 34. The liquid crystal panel drive circuit 34 vertically inverts the scanning direction of a liquid crystal panel 33 in response to the detection signal c1. Thus, video light projected by a video projector part 21 is directed in the correct direction.
