Abstract
Provided is a multi-projector system including: projectors; an image outputting apparatus; and an adjusting apparatus to adjust images. Each of the projectors includes: a light-emitting unit to emit the modulated light; and a color adjusting unit to adjust colors of the projected image. The image outputting apparatus includes an outputting unit to output the first adjustment image and the second adjustment image as the input images of the projectors. The adjusting apparatus includes: an imaging unit to take a projected image and to output a captured image; an analyzing unit to analyze an image of the overlapping area from the captured image so as to determine a color component; and a controller for controlling the color adjusting unit of the first projector so that the color of the overlapping area is an achromatic color in accordance with the color component determined as a result of the analysis.
