<P>PROBLEM TO BE SOLVED: To provide a projection video display device that allows imaging in a desired direction by a camera built in a projection video display device, regardless of the installation state of the projection video display device. <P>SOLUTION: An imaging means is composed of a first camera for imaging the direction almost the same as the projection direction and a second camera for imaging the direction almost orthogonal to the projection direction. The imaging means is provided with a posture detection means for detecting the installation state of a projection video display device, and a selection means for operating either of the first and second cameras by alternatively selecting either of the first and second cameras on the basis of the detection result of the posture detection means. <P>COPYRIGHT: (C)2009,JPO&INPIT |
