<p>A projector device, which is simple and small and able to display images brighter and also able to improve the usefulness considerably. The effective reflecting lights of the mirror deflection type light modulators are focused into images at the position right in front of the projection lens, and the effective reflection lights are partly turned and focused on the two-dimensional position detector means for detecting the vertical and horizontal positions of the formed images. Then, based on the detected information from the two-dimensional position detector means, the mirror deflection type light modulators are finely displaced in the vertical and horizontal directions, or the mirror deflection type light modulators are finely displaced in the vertical direction and the synthesizing mirror means is finely displaced in the direction of focal length, so that the positions of the effective reflection lights of at least two mirror deflection type light modulators are adjusted, therefore the discrepancy of the positions among the colors can be effectively corrected and the image quality can be considerably improved.</p> |
