PROBLEM TO BE SOLVED: To secure easiness in viewing a specific image even when the specific image is displayed in an overlap region in partial overlap projection.SOLUTION: Respective partial regions of a first image projected from a first image projection device 210 and a second image projected from second image projection devices 211-213 are displayed while superposed on one another. The first image projection device has correction means 26, 36 of making both the image projection devices perform superposition correction processing on the superposition regions of the first and second images, and at lest one of the first and second image projection device is made to display a specific image included in a part of a composite image. When the specific image is displayed including the superposition regions, the correction means does not make the first and second image projection devices perform the superposition correction processing on a part, where the specific image is displayed, of a partial region of one of the first and second images, and makes a part, where the specific image is displayed of the other low in illuminance.SELECTED DRAWING: Figure 2 |
