摘要： Provided is an image projection apparatus including: one or more light sources; one or more illumination optical systems; a first reflection-type light valve group including three light valves and being configured to modulate incident light based on first image information; a second reflection-type light valve group including three light valves and being configured to modulate incident light based on second image information; a first prism-type photosynthesizing member having a function of synthesizing, on one optical axis, light that is reflected by the first reflection-type light valve group; a second prism-type photosynthesizing member having a function of synthesizing, on one optical axis, light that is reflected by the second reflection-type light valve group; and a prism-type beam splitter configured to synthesize, on one optical axis, light that has been reflected by the first reflection-type light valve group and light that has been reflected by the second reflection-type light valve group.
