Abstract
The image processing apparatus includes a lamp, fly eye lenses, an R reflective dichroic mirror, an R liquid-crystal light valve, a G reflective dichroic mirror, a G liquid-crystal light valve, a B dichroic light valve, a dichroic prism, and a projection lens for projecting a synthesized color image. In addition, a color-impurity correcting filter is provided typically between the R reflective dichroic mirror and the mirror to form an inclination angle of 10 degrees with a normal axis Y perpendicular to the incident-light axis X in the clockwise rotational direction around a normal axis Z. As a result, the color purity of the image displayed on the screen is improved and the luminance distribution of the displayed image can also be made uniform as well.
