In [[3D computer graphics]], the '''image plane''' is that [[Plane (mathematics)|plane]] in the world which is identified with the plane of the display monitor used to view the image that is being rendered. It is also referred to as [[screen space]]. If one makes the analogy of taking a [[photograph]] to rendering a 3D image, the surface of the film is the image plane. In this case, the [[viewing transformation]] is a [[3D projection|projection]] that maps the world onto the image plane. A rectangular region of this plane, called the viewing window or [[viewport]], maps to the monitor. This establishes the mapping between [[pixels]] on the monitor and points (or rather, rays) in the 3D world. The plane is not usually an actual [[geometric object]] in a [[3D scene]], but instead is usually a collection of target coordinates or dimensions that are used during the [[rasterization]] process so the final output can be displayed as intended on the physical screen.

In [[optics]], the image plane is the plane that contains the object's projected image, and lies beyond the back [[focal plane]].<ref name=PHIP1>{{cite web|url=http://www.photokonnexion.com/definition-focal-plane-film-plane/|title=Definition: Focal Plane; Image Plane; Film Plane; Sensor plane|access-date=18 November 2017}}</ref>
