Abstract: A deposition mask package according to the present embodiment includes a receiving portion, a lid portion that faces the receiving portion, a deposition mask that is arranged between the receiving portion and the lid portion and has an effective region in which a plurality of through-holes is formed. The receiving portion has a first opposing surface facing the lid portion and a concave portion provided on the first opposing surface. The concave portion is covered by a first flexible film. The effective region of the deposition mask is arranged on the concave portion with the first flexible film interposed therebetween.

Abstract: A target color is set on the basis of a first captured image obtained by capturing, with an imaging section, at least a part of a first image projected by a projection optical system of a projector. First correction data for correcting a color of a projected image of another projector to the target color is calculated on the basis of a second captured image obtained by capturing, with the imaging section, at least a part of a second image projected by the projection optical system of the other projector.

Abstract: An image projection system includes a first projector and a second projector. The first projector includes a first projection section that projects a first image and a first imaging section that captures an image of an area including the first image. The second projector includes a second projection section that projects a second image and a second imaging section that captures an image of an area including the second image. The image projection system further includes a computation section that determines first luminance adjustment information used to adjust the luminance of the first image and second luminance adjustment information used to adjust the luminance of the second image based on the luminance distribution of the first image determined from the image captured by the first imaging section and the luminance distribution of the second image determined from the image captured by the second imaging section.

Abstract: Projectors include a first projector that projects a first image and a second projector that projects a second image. The first projector includes a first control section that corrects the first image based on a first captured image produced by capturing an image of the range containing at least part of the first image and part of the second image and with reference to a target area contained in the range over which the first captured image is captured, and the second projector includes a second control section that corrects the second image based on a second captured image produced by capturing an image of the range containing part of the first image and at least part of the second image and with reference to the target area contained in the range over which the second captured image is captured.
