Title: Photographic recording from a video monitor
Inventor: CESCHIN RANIERI
IPC: B41J2/44
Filed: 1983-09-21
Abstract: The recording apparatus comprises a video signal input (5a), a video monitor (2,5 to 12) connected thereto for converting the received video signals into images displayed on a screen of the monitor, support means for a photographic medium (4) to be exposed to the images displayed by the monitor (2,5 to 12), and an optical system (3), such as a wide angle lens, operatively interposed between the screen of the video monitor (2,5 to 12) and the photographic medium (4). A compensation circuit (13) is connected to the monitor (2,5 to 12) to modify the brightness of the image displayed in such a way that it complements the illumination characteristics of the optical system (3) whereby the image recorded on the photographic medium (4) exhibits negligible or zero vignetting. The intensity of light transmitted through a wide angle lens varies as COS<4> gamma where gamma  is the angle of illumination with respect to the lens axis. Double integration circuits (14,15) generate parabolic signals at line and field rate which are combined and used to control the bias of the control grid (7c). <IMAGE>
