ABSTRACT:
A front projection type multi-projection display includes a plurality of projector units to modulate and project light from a light source based on image information, an image-capturing device disposed in a housing to capture predetermined regions of the projection images projected onto the screen, a unit image information generating unit to generate image information to be input to each of the plurality of projector units, and a unit image information correcting unit to correct the unit image information based on a result captured by the image-capturing device. Therefore, it is possible to perform the adjustment process and to further reduce the adjustment time.
