The projection display device projects a guide display image suggesting an adjustment of the installation position of the projection display device, projects a correction image in a prescribed shape in the projection of the guide display image, measures a projection distance based on the captured image obtained by capturing the correction image, and performs a focus adjustment to a projected image, thus projecting a focused guide display image. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
