Abstract: A device to produce a color image, the device including a color filtering arrangement to sequentially produce at least four colors by transmission through respective color filters, each color filter having a spectral range of transmission, wherein the spectral range of at least one of the color filters includes substantially the entire spectral range of at least one additional color filter. A method of producing a color image, the method including sequentially transmitting light of at least four colors through at least four color filters respectively, each color filter having a spectral range of transmission, wherein the spectral range of at least one of the color filters includes substantially the entire spectral range of at least one additional color filter.

Abstract: A method and system for converting color image data (data outputting from element 202) from a, for example, three-dimensional color space format to a format usable by an n-primary display (206), wherein n is greater than or equal to 3. The system (converter 204) may define a two-dimensional sub-space having a plurality of two-dimensional positions, each position representing a set of n primary color values and a third, scaleable coordinate value for generating an n-primary display input signal (signal inputting toi display 206). Furthermore, the system may receive a three-dimensional color space input signal including out-of range pixel data not reproducible by a three-primary additive display, and may convert the data to side gamut color image pixel data suitable for driving the wide gamut color display.

Abstract: A device (300) to produce a color image using four or more primary colors. The device may include four or more transmissive spatial light modulators (309, 310, 311, 312) to modulate four or more, respective, light beams in accordance with four or more, respective, primary color image components of the color image to produce four or more, respective, modulated light beams. The device may also include a beam combining arrangement (320) to combine the four or more modulated light beams into a combined light beam carrying the color image.

Abstract: A device, system and a method for soft proofing of an image before it is printed onto printed material, such that the colors of the image substantially reproduce, to the human eye, the colors as they should appear on the printed material.

Abstract: A color Liquid Crystal Display (LCD) device for displaying a color image using at least four different primary colors, the device including an array of Liquid Crystal (LC) elements (214), driving circuitry (218) adapted to receive an input corresponding to the color image and to selectively activate the LC elements (214) of the LC array to produce an attenuation pattern corresponding to a gray-level representation of the color image, and an array of color sub-pixel filter elements (216) juxtaposed and in registry with the array of LC elements (214) such that each color sub-pixel filter element is in registry with one of the LC elements, wherein the array of color sub-pixel filter elements comprises at least four types of color sub-pixel filter elements, which transmit light of the at least four primary colors, respectively.

Abstract: A device, system and a method for displaying image data of a plurality of colors, the device comprising a light source (50) for producing light having at least four primary colors, a controller (56, 58) for determining a combination of at least four primary colors according to the image data (72) for production by the light source and a viewing screen (60) for displaying the image data the combination from the controller. The present invention is not limited to combinations of colors which are produced from only three primary colors, such as red, green and blue.
