Image projection system that enables almost complete superposition without any image shift in superposition projection of original images a plurality of image projection apparatuses

摘要

For providing the image projecting system capable of substantially superimposing images without image blur which are provided from a plurality of image projecting apparatus when the original images are superimposed using the plurality of image projecting apparatus, distortion value of distortion aberration of images from projecting optical system comprised in the image projecting system is made substantially coincided in a region of using image height.
