An apparatus for projecting video image comprises a CPU for producing all kinds of controll signals, a signal converting circuit, a Firstin First-out memory unit for converting the digital video signal streams into the video signal streams with time character, a serial/parallel converting unit and a playing unit for playing video image of color visible light. The apparatus also comprises three primary colors emitting diode lines for producing color visible light, convergent lens lines for converging color visible light, lumen emitting diode element, light beam lens, light beam slit, mirror surface triple prism or mirror surface multiprism for receiving and reflecting the mixed color visible light and negative lens for receiving single direction diffuseness of mixed color visible light and projecting on the screen, so that the received analog singal streams can product sequential dynamic color visible picture. The apparatus for projecting video image of the present invention is portable and has low power loss and low cost. The definition of projection and the lumen illumination are improved and the electromagnetic noise is reduced by utilizing the present invention. The present invention also relates to the method for projecting video image.
