(uncountable, film) The method or practice of adjusting widescreen film images, especially 2.35:1 or 2.39:1 aspect ratio, so that they can be shown within the proportions of a 1.33:1 or 1.78:1 aspect ratio television screen, by cropping off sides of the original widescreen image, as opposed to letterboxing.

(computer graphics) To compose a digital image from multiple assets, such as photos and 3D models, with artistic interpretation to modify and blend them together seamlessly.
n
The displaying of a narrow format video or image with blank stripes on each side on a wider screen.
n
A technique to prevent screenburn by periodically moving the entire video frame by an imperceptible amount.
n
(computer graphics, video games) A performance issue in three-dimensional graphics, causing objects or textures to "pop" suddenly into view as they are loaded, rather than smoothly moving into view.
n
(photography) A circular vignette-like defect where the image fades at the borders.
n
A form of beamforming that supports multi-layer radio transmissions
n
(electronics) A counting circuit used to reduce a high-frequency electrical signal to a lower frequency by integer division.
n
(signal processing) The conversion of video footage to a higher frame rate by duplicating certain frames.
n
An electronic device that samples a varying quantity (e.g. a waveform) and generates a digital response
n
(electronics) A receiver used in conjunction with an interrogator to receive and interpret signals from a transponder.
v
(computing, medicine, transitive) To create an image of something with the use of a scanner.
n
An event at which people digitize a large amount of archival material.
n
The path followed by the viewer's eyes when reading a document or observing a scene.
n
(education) The prepared forms used in such devices.
n
When the image on a screen appears to horizontally "tear" in two due to lack of synchronization between the video feed and the display's refresh rate.
