Abstract
A liquid crystal display projector combined with a video printer is capable of copying a desired picture being displayed on a screen as a photograph. The combination of a liquid crystal display projector and a video printer has a projection optical system including a concave mirror, an LCD panel, a projection lens, and a partial reflective mirror provided between the LCD panel and the projection lens. A copier optical system is also included which has a total reflective mirror, a copier lens, an LCD shutter, and photographic film on which an image signal passing through the partial reflective mirror is formed. A control circuit supplies a video drive signal to the LCD panel and a shutter output control signal to the LCD shutter when a copy selection signal is applied to the control circuit. Still picture data are outputted and applied through the LCD driver to the LCD panel so that the image passing through the copier lens is formed on the photographic film.
