<p>PURPOSE:To prevent a color slurring without making necessary a synthesizing adjustment by successively outputting primary-colored or black colored color- separated pictures to a picture output device, synchronizing a primary colors filter with respective color pictures in a projection optical path, successively inserting and synthesizing the color picture on a projection surface. CONSTITUTION:A lamp 8 is turned on by pressing a switch 5b and its light is transmitted through a liquid crystal displaying device 6. The displayed picture of the device 6 passes through a filter holding plate 11 and a projection lens 10, is reflected by a reflection mirror 16 and projected on a screen 16. Pictures separated into R, G and B primary colors or black color are successively displayed on the device 6, the filter holding plate 11 is rotated in accordance with this order and the R, G and B filters are successively inserted into the optical path. The respective pictures are colored by the filters R, G and B corresponding to the colors of the pictures, projected on the screen 16 by the projection lens 10 and the color picture can be synthesized on the screen 16 by using the afterimage effect of eyes.</p> |
