An image projection system for projecting an image obtained on an image field onto a screen through a projection lens comprises a plurality of spacers overlaid with each other and arranged between the image field and the lens, each of the spacers having first and second surfaces through which the image is projected and an angle defined by the first and second surfaces being a predetermined value, an adjusting device for each of the spacers for adjusting a rotational angle of the spacers on a rotational axis substantially parallel to an image projection direction, and a fixing device for fixing the plurality of spacers relative to the image field and the lens. <IMAGE> |
