METHOD FOR ADJUSTING LIGHT QUANTITY OF PROJECTION SYSTEM, PROJECTION SYSTEM AND PROJECTOR

摘要

PROBLEM TO BE SOLVED: To provide a method for adjusting a light quantity of a projection system, a projection system and a projector.;SOLUTION: In the method for adjusting the light quantity of the projection system in which a light quantity in an overlapping area is adjusted: a first procedure S2 for setting a plurality of light quantity decay curves from an inside end to an outside end in the overlapping area in a projection image by the projector; a second procedure S3 for simultaneously displaying a display image in accordance with each of the light quantity decay curves in the overlapping area; a third procedure S5 for selecting the display image that is most excellently displayed from a plurality of display images displayed simultaneously; and a fourth procedure S2 for setting a plurality of different light quantity decay curves again on the basis of the light quantity decay curve related to the selected display image are performed. By recursively repeating the first to fourth procedure S2, S3 and S5, the optimum light quantity decay curve is selected.;COPYRIGHT: (C)2010,JPO&INPIT
