<P>PROBLEM TO BE SOLVED: To provide a display position adjusting method and the like for highly accurately adjusting a display position of a projection image without being affected by the distortion of the projection image caused by a projector. <P>SOLUTION: A display position adjusting method for adjusting a display position of at least one of a first projection image and a second projection image displayed on a projection screen includes a pixel deviation detecting step for detecting pixel deviation that is in a position of each pixel constituting the second projection image with respect to a position of each pixel constituting the first projection image, a pixel deviation correcting step for correcting the pixel deviation using a pixel position correction value corresponding to an error amount with respect to a reference pixel position in each projection image, an adjusting amount calculating step for calculating an adjusting amount of the display position of at least one of the first projection image and the second projection image based on the corrected pixel deviation, and a display position adjusting step for controlling to adjust the display position of at least one of the first projection image and the second projection image based on the adjusting amount. <P>COPYRIGHT: (C)2011,JPO&INPIT |
