Title:
PROJECTION SYSTEM, PROJECTOR, AND IMAGE ADJUSTMENT METHOD
Document Type and Number:
Japanese Patent JP2017129707
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To correctly perform measurement of an adjustment image.SOLUTION: A projection system includes a plurality of projectors projecting images arranged side-by-side on a projection surface, a control device, and an imaging unit. The projectors are classified into N (N is equal to 2 or more) projector groups. The control device causes adjustment images to be projected on the projection surface at different timing for each projector group, and causes the projection surface projected with the adjustment images to be sequentially imaged by the imaging unit. At least one projector group of the N projector groups includes two or more projectors. The two or more projectors project the adjustment images at positions not adjacent to each other on the projection surface.SELECTED DRAWING: Figure 3
