1. An image projection apparatus comprising:
at least three light sources configured to respectively emit laser lights of colors different from each other;
at least one display element configured to modulate each of the laser lights emitted from the at least three light sources, on the basis of a video signal;
an illumination optical system configured to guide the laser lights emitted from the at least three light sources, to the display element; and
a projection lens configured to project the laser lights modulated by the display element, wherein
the illumination optical system separately includes
an optical element of a first system configured to uniformize an intensity distribution of one of the laser lights emitted from one of the at least three light sources and guide resultant laser light to the display element,
an optical element of a second system, being different from the optical element of the first system, configured to uniformize an intensity distribution of another of the laser lights emitted from two other of the at least three light sources and guide resultant laser light to the display element,
the laser lights emitted from the at least two other of the light sources are guided to the optical element of the second system, and
beam profiles of the laser lights incident on the optical element of the second system are similar to each other compared with the beam profiles of the laser lights incident on the optical element of the first system.
