Looming

Looming, in reference to vision and perception, refers to rapid size expansion of a visual image. As an image suddenly appears larger (looms) on the retina of the viewer it causes the viewer to perceive that the image is coming closer or retreating. For instance, if a person is exposed to visual images of a moving car or train and that image is manipulated to appear larger or smaller it will give the impression of forward or backward movement.
