Definity
DEFINITY is a digital film recorder based on LCD technology , which is primarily used in the film industry . The system is manufactured and distributed by CCG Digital Image Technology, the successor to the Agfa-Gaevert film recorder branch .
When it was launched on the market in 2004, Definity marked a departure from the solutions previously used in film recording with its LCD imager, which were primarily based on analog technologies such as B. used cathode ray tubes .
Until then, LCD technology, despite its great potential, was largely unsuitable for digital film recording . a. failed due to insufficient color depth (8 bit instead of the 10 and 12 bit required in the film industry), insufficient color saturation or insufficient exposure speed on intermediate material. The monochrome LCD imager that is built into Definity avoids these problems. a. in that it combines sharp-edged dichroic filters and is partially fed with light in the near-infrared range . The necessary bit depth is achieved through multiple exposure of 8-bit individual images.
In the course of the digital intermediate , Definity is often used together with color management systems such as B. Baselight used by FilmLight.
At the NAB 2010 in Las Vegas, CCG introduced a new light source based on LED technology for Definity. Until then, CCG had been using a version of the Planon gas discharge lamp specially manufactured by Osram .
