<P>PROBLEM TO BE SOLVED: To provide a projector device that permits ready and fast changing of the optical axis direction of its camera even if the state of installation, including the place and conditions of installation, is different. <P>SOLUTION: A projector device that projects images in a projecting direction is provided with a camera whose view angle of the shooting field is reverse to the projecting direction of a mirror; a gravity sensor that detects the state of installation of the projector device; an image processing unit that processes images shot by the camera; and a CPU that controls the projector device. The CPU exercises control according to the state of installation detected by the gravity sensor, causing the image processing unit to give an output at a 0° rotation angle of the output image of the camera when the projector device is in a stationary state of installation or at a 180° rotation angle of the output image of the camera when the projector device is in a suspended state of installation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
