Claim 2:
3. The adjustment method according to claim 2, further comprising:
causing the projector to sequentially project as the second image a first monochromatic image and a second monochromatic image, brightness of the first monochromatic image is uniform in the image, brightness of the second monochromatic image is uniform in the image, and the brightness of the first monochromatic image and the brightness of the second monochromatic image are different;
estimating the range of the first brightness based on the brightness of the first area and the brightness of the third area, the first area detected when the first monochromatic image is projected, the brightness of the first area detected when the second monochromatic image is projected; and
estimating the range of the second brightness based on the brightness of the second area detected when the first monochromatic image is projected, the brightness of the second area detected when the second monochromatic image is projected, and the brightness of the fourth area.
