Explanation:

We know that  when an object is closer to a convex lens than one focal length, the image is a virtual, erect and enlarged image is formed at the same side of lens, when an object is placed between principal focus and optical center of a convex lens.

Hence, If an object is closer to a convex lens than one focal length, the image is enlarged.
