An object is to provide an image projection system in which a size and weight of a head-mounted portion are reduced and binocular vision is enabled.The present technology provides an image projection system including an image projection apparatus and an image display light diffraction optical element separated from the image projection apparatus and arranged in front of each of the two eyes, and the image projection apparatus includes: a positional information acquisition unit that acquires three-dimensional positional information of the image display light diffraction optical element provided in front of each of two eyes; an image display light adjustment unit that adjusts projected image display light on the basis of the three-dimensional positional information acquired by the positional information acquisition unit; and one projection optical system that can project the image display light to a region covering the two eyes and projects, toward the image display light diffraction optical elements, the image display light adjusted by the image display light adjustment unit.
