SMALL PROJECTION APPARATUS AND ITS INSTALLATION LOCATION ADJUSTING METHOD, AND PARAMETER ADJUSTING METHOD FOR SMALL PROJECTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a small projection apparatus whose light volume to be projected is adjustable when the apparatus is moved to a new installation location, and which is quickly and easily re-installed when it is returned to the original installation location.;SOLUTION: The small projection apparatus comprises sensors for detecting changes in tension and angle of an attached string (strap) and detecting changes in movement. After a setting position is determined from changes of tension and angle of the sensors, projected light is decreased or turned off, or a video signal mute (black) is sent, according to a change in the setting position of the small projection apparatus. The small projection apparatus once established in a suitable position, is moved to a new installation location because of reception problem, and again the apparatus can be established quickly and easily on the suitable original installation location.;COPYRIGHT: (C)2008,JPO&INPIT
