image

Picture or appearance of a real object, formed by light that passes through a lens or is reflected from a mirror. If rays of light actually pass through an image, it is called a real image. Real images, such as those produced by a camera or projector lens, can be projected onto a screen. An image that cannot be projected onto a screen, such as that seen in a flat mirror, is known as a virtual image.

In a pinhole camera, rays of light travelling from the object through the pinhole of the camera form a real image on the screen of the camera. The image is upside down, or inverted.

In mathematics, a point or number that is produced as the result of a transformation or mapping.
