A device for projecting a color image upon a screen, including color image recording and color image reproduction with an enhanced color reproduction trueness in comparison to conventional processes. In the device two images are recorded in parallel, which separately detect the shorter and the longer wavelength parts of the individual principle color spectral regions. In image reproduction six primary valences are produced, which respectively comprise the image information of the shorter and the longer wavelength parts of each of the individual principle color spectral regions. In an alternative embodiment the device produces a full color, stereoscopic image reproduction, in which the three primary valences of the respective shorter wave part encode a stereoscopic half image and the three primary valences of the respective longer wavelength part encode the other stereoscopic half image.
Device for projecting a color image upon a screen (S) including a projection lamp (PL) for emission of a radiation spectrum, a beam splitter (ST2) for separation of the radiation spectrum into a first partial light bundle (B1, G1, R1) and a second partial light bundle (B2, G2, R2) complimentary to the first part light bundle (B1, G1, R1), two color image modulators (FM1, FM2) for recording and reproducing the partial light bundles (B1, G1, R1, B2, G2, R2) wherein after the color image modulators (FM1, FM2) a beam integrator (SV) is provided for reuniting the first partial light bundle (B1, G1, R1) with the second partial light bundle (B2, G2, R2) as well as a lens system (Ob) for output of the therefrom resulting color image.
