IMAGE PROJECTION APPARATUS

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.

1. An image projection apparatus comprising:
one or more light sources configured to emit light including one or more of three primary colors of light; one or more illumination optical systems configured to illuminate light from the light sources; a first reflection-type light valve group including three light valves corresponding to the three primary colors of light, the first reflection-type light valve group being configured to modulate incident light from the illumination optical systems based on first image information; a second reflection-type light valve group including three light valves corresponding to the three primary colors of light, the second reflection-type light valve group being configured to modulate incident light from the illumination optical systems 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, the light having been separated into the three primary colors; 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, the light having been separated into the three primary colors; 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 modulated based on the first image information and light that has been reflected by the second reflection-type light valve group and modulated based on the second image information.
