PROBLEM TO BE SOLVED: To suppress occurrence of unnatural variation in luminance and marked reduction in luminance and contrast which are conventionally caused by luminance correction in the superimposed area of a multi-projection system.SOLUTION: The multi-projection system is composed of plural projectors so arranged as to form a combined projection area by superimposing at least portions of the projection areas of the respective projectors on each other, and corrects image data to be projected, such that luminance distribution between two points in a horizontal or vertical line in the combined projection area becomes luminance distribution regulated by a concave function, on the basis of the luminance properties of the plural projectors. |
