ABSTRACT:
A video projecting apparatus for projecting a compound image onto a projection screen includes a single cathode ray tube having a face plate with red, green and blue color phosphor screens sequentially arranged thereon, for example, in the horizontal line scanning direction, and an electron gun for generating an electron beam to sequentially scan the color phosphor screens as the beam is modulated by respective red, green and blue color components of a video signal; a source of a video signal; a memory device for simultaneously storing at least the red, green and blue color components of the video signal at a first rate during each horizontal line scan period; and a transmitting device for sequentially transmitting from the memory device, at a second, faster rate during the next horizontal line scan period, the red, green and blue color components earlier stored in the memory device for modulating the electron beam in the cathode ray tube as the beam sequentially scans the respective color phosphor screens, and in which the red, green and blue color components are sequentially transmitted within the time required to store each color component in the memory device.
