Erect image
From Wikipedia, the free encyclopedia
An erect image, in optics, is one that appears right-side up. Some telescopes and other devices, such as the camera obscura present an inverted image on the viewing surface. Various means are used to achieve an erect image. A common example of an erect image is the image of a person in a standard plane mirror.
