If one - half of the convex lens is covered with a black paper then also will produce a complete image because a image is formed by many  rays of light and for formation of image only two rays of lights are sufficient. But the intensity of light of light will get decreased due to which the image will look less brighter .

As the image is formed by a large number of rays from the object, so if any part of the lens is covered, the image will form. The brightness of image will be less compared to the image formed without wrapping the lens.
