PROBLEM TO BE SOLVED: To provide a video adjustment system by which relative positioning of video images projected from a plurality of projectors is allowed using a test video image output from a single video output terminal. SOLUTION: A video generator has: generation means for generating a single test video image including a plurality of patterns Pa, Pb for adjustment associated with each projector, respectively; and a video output terminal which projects the patterns Pa, Pb for adjustment from each projector by outputting a video signal of the test video image to each projector. Each of the patterns Pa, Pb for adjustment is composed of a graphic constituting the cross shape by a vertical side and a horizontal side. Here, attributes different from each other are given to each of the patterns Pa, Pb for adjustment by setting the pattern Pa for adjustment corresponding to a first projector so that its horizontal side is longer on the left side rather than on the right side of its vertical side, and setting the pattern Pb for adjustment corresponding to a second projector so that its horizontal side is longer on the right side rather than on the left side of the vertical side.
