<p>A color video printer having a color viewer for viewing a color video image before printing to permit evaluation of the image and if necessary, preprinting adjustments to the characteristics of the image. The color video printer includes a monochrome display device (CRT) (32) for displaying an image of a color video signal to be copied and an exposure station (36) which is located along a first optical path from the display device and at which is positioned a self-processing photographic element (38). An optical assembly (53) is movable between a position out of the first optical path and a position intercepting the first optical path to establish a second optical path between the display device and a color image viewing station (45). First and second rotatable filters (39, 46) have respective red, green and blue filters which are sequentially moved into the first and second optical paths in synchronism with the field frequency of the video signal. A selectively actuatable coupling (56) moves the optical assembly (1) to the position out of the first optical path to permit exposure of a self-processing photographic element located at the exposure station to a sequence of color field images produced by the CRT and the first filter, and (2) to the position establishing the second optical path to permit viewing at the viewing station of color images produced by the CRT and the second filter.</p> |
