Title:
MULTI-PROJECTOR SYSTEM, PROJECTOR DEVICE, ADJUSTMENT DEVICE AND ADJUSTMENT METHOD, AND ADJUSTMENT PROGRAM
Document Type and Number:
WIPO Patent Application WO/2015/008765
Kind Code:
A1
Abstract:
A first adjustment-use projection image (301) projected by a first projector device has formed therein an adjustment region (331) which includes a first and second region the luminance inclination directions of which are mutually orthogonal. A second adjustment-use projection image (302) projected by a second projector device has formed therein an adjustment region (332) which includes a third region the luminance inclination direction of which is the reverse of that of the first region but the position of which corresponds to the first region, and a fourth region the luminance inclination direction of which is the reverse of that of the second region but the position of which corresponds to the second region. A projection image, which is the first and second adjustment-use projection images that are projected so as to have an overlapping region (33') corresponding to the adjustment regions, is captured and the captured image is analyzed. A first luminance of a region which is included in the overlapping region (33') and in which the first and third regions overlap, a second luminance of a region in which the second and the fourth regions overlap, and a third luminance of regions other than the overlapping region are obtained, and in order that the first and second luminance each match the third luminance, the projection position of the projection image of the first projector device is adjusted.
