Combining multiple pictures into a single image is called a montage or composite. In retinal imaging, this means stitching together several fundus photographs to create one wide-field view that shows more of the retina than any single image could. The process aligns frames using recognizable landmarks like blood vessels and optic disc features, then merges them into a seamless panorama. This is essential for documenting peripheral areas, tracking disease spread, and making consistent comparisons across the retina.

The other terms describe different things: noise is random grain in an image that degrades quality, brightening refers to increasing overall exposure, and blooming is the overflow of charge from bright areas into adjacent pixels, creating halos. None of these involve stitching multiple pictures into one image.
