film recorder
A film recorder is a graphical output device for transferring images to photographic film from a digital source. In a typical film recorder, an image is passed from a host computer to a mechanism to expose film through a variety of methods, hi ...
produced by CCG Digital Image Technology, designed for motion pictures. It succeeded
Agfa-Gevaert's film recorder division and was launched in
Las Vegas at
NAB in 2004.
Overview
Definity uses a
monochrome high resolution
Image resolution is the detail an image holds. The term applies to digital images, film images, and other types of images. "Higher resolution" means more image detail.
Image resolution can be measured in various ways. Resolution quantifies how cl ...

A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly but in ...
panel to record digital sequences onto motion picture film, rather than the analog technologies previously used. Prior to Definity's release, LCD technology was thought to be unsuitable for film recording due to its limitations in
bit depth, temporary image retention (TIR), and less

In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device.

CinemaScope
CinemaScope is an anamorphic lens series used, from 1953 to 1967, and less often later, for shooting widescreen films that, crucially, could be screened in theatres using existing equipment, albeit with a lens adapter. Its creation in 1953 by ...
" material without sacrificing horizontal image information. By using its anamorphic pixels (with an
aspect ratio of 3:1) instead of the standard square pixels, flat
widescreen material with an aspect ratio of 2.36:1 can be horizontally compressed on the LCD, resulting in a 1.18:1 image that can be transferred onto film without sacrificing image information.

The contrast ratio (CR) is a property of a display system, defined as the ratio of the luminance of the brightest shade (white) to that of the darkest shade (black) that the system is capable of producing. A high contrast ratio is a desired aspec ...
