According to the Physics Classroom, "When the object is located at the focal point, no image is formed."

Yes, but it doesn't just float there in thin air. You need something there to make the image show up, such as smoke, tissue paper, fog, steam, ground (frosted) glass, etc. If you don't have any of those, you can take a short-focus eyepiece and look at the focal point with it. In the eyepiece, you'll see the image at the focal point. (It won't look like an image. It'll look like the object.)

When an object is seen moving in relation to a stationary object is called the frame of reference
The image seen through a convex lens will appear upright and enlarged when the object being viewed is within the focal length of the lens.
This is usually called a reference point. Frame of reference is not an incorrect term, but it is used less frequently.
An object is seen less in the lens as a whole because it magnifies a specific part of the object.

A single lens reflex (SLR) is a camera that uses the same set of lenses to both focus the image on the CCD (digital) and enable the photographer to frame the picture. That is to say, when you look through the viewfinder of a DSLR you are looking directly at the object through the main lens. You are not looking at the digitally re-created picture of the object or through some other lens that is off-center of the main lens. A point-and-shoot camera will have some other mechanism for framing the picture.

prevent its disappearance due to the decrease in the field of viewTo do just that... center the object, because when the magnification is increased, the lens zooms in on the center, cutting out the perifery.
