<P>PROBLEM TO BE SOLVED: To provide an image projection apparatus capable of properly correcting a temperature drift and correcting a trapezoid, even when the apparatus is set at a tilt in any direction. <P>SOLUTION: The apparatus 1 includes: an acceleration sensor 2 for measuring acceleration in three directions of measuring axes, which are each perpendicular; a correcting angle calculation section 10 for calculating a setting angle of the apparatus from results measured by the acceleration sensor 2; an image processing means 4 for correcting the trapezoid of an image based on the setting angle calculated by the correcting angle calculation section 10; and an image projection means 6 for displaying the image whose trapezoid is corrected on a screen. <P>COPYRIGHT: (C)2011,JPO&INPIT |
