摘要： A display apparatus includes a color image projection unit and a screen. The color image projection unit includes a converter which receives image signals of three primary colors, and converts the received image signals of three primary colors into image signals of four or more primary colors, and a color image projector which includes a plurality of image projection devices having respective primary colors, and which receives the image signals of four or more primary colors, and projects the received image signals of four or more primary colors onto the screen. The color image projector is capable of physically adjusting positions of the image signals of four or more primary colors, which are projected onto the screen such that the positions of the image signals are coincident with each other.

摘要： A color reproduction system includes a color conversion unit for displaying a color image on a multi-primary-color display. The color conversion unit includes a maximum brightness signal calculating unit for calculating signals corresponding to three color reproduction area corners as the corners of a plane that constitute a color reproduction area surface of the display. The three color reproduction area corners surround the vectors of input tristimulus values. The maximum brightness signal calculating unit also calculates a weighting factor obtained when the input tristimulus values are expressed as a linear sum of the tristimulus values of the color reproduction area corner vectors. The color conversion unit further includes a color image signal calculating unit for calculating a color image signal used to display the input tristimulus values, on the basis of the signals corresponding to the color reproduction area corners and the weighting factor. The color reproduction system can realize colorimetrically accurate reproduction, provide continuity between XYZ data and signal values, and use the color reproduction area to the maximum extent.
