An image projection apparatus includes an image processing device, an illuminating device, a light valve, and a projection optical system; wherein the projection optical system is formed in such a way that at least one of a first deviation corresponding to an amount of the magnification chromatic aberration of a light having a central wavelength of the red light relative to the green light and a second deviation corresponding to an amount of the magnification chromatic aberration of the blue light relative to the green light is larger than a fixed-pixel pitch, and a third deviation corresponding to an amount of the magnification chromatic aberration of a light having a maximum wavelength of the red light relative to a light having a minimum wavelength of the red light is not larger than the fixed-pixel pitch; wherein the first deviation and/or the second deviation is eliminated by supplying the compensated video signal to the light valve. |
