How does a convex lens typically affect images?

A convex lens can indeed produce both upright and inverted images depending on the position of the object relative to the focal point of the lens. When an object is placed outside the focal length of the lens, the image formed is inverted and real. Conversely, when the object is within the focal length, the image produced is upright and virtual.

This dual capability allows for various applications of convex lenses in devices such as cameras, projectors, and magnifying glasses, where the orientation of the image is crucial for the functionality of the device. Thus, the most accurate characterization of how a convex lens typically affects images is that it can produce both upright and inverted images depending on the object's distance from the lens.
