Abstract
A new method is proposed for the compensation of color distortion between the right and left sides of a projected image in an LCD projection system. The deviation of the incident beam angle causes the difference in spectral transmittance between the sides of a dichroic mirror, and the color distortion resulting from this difference is analyzed by the colorimetric method. In the compensation method, the variation of the transformation matrix between the Commission Internationale de I’Eclairge (CIE) XYZ tristimulus values and RGB primary values is linearly approximated under reasonable assumptions based on typical LCD projection systems. The proposed method can be simply implemented with an on-line scheme to be practically applicable to projection TV systems and its effectiveness is shown via experimental image examples.
