ABSTRACT:
Image qualities of a full color image can be changed as needed by arranging two flat round color filter plates so as to overlap each other in part and so as to be selectively rotationally driven. Further, these color filter plates and are set so that the color characteristics thereof are mutually different from each other. White light from a lamp is injected into an overlapping portion A of these color filter plates, but this white light is converted into light of each single color as the color filter plate is rotationally driven, and this light irradiates an image display element. At the image display element, an image is switched or changed in synchronization with the irradiation of the light in single colors; therefore, the image is recognized as a color image and the colors of a plurality of color images are mixed to be seen and recognized as full color image. The image qualities of this image are switched or changed by means of changing the driven color filter plates.
