A system and method for performing color correction based on physical measurements (or estimations) of color component spectra (e.g. red, green, blue color component spectra). A color correction system may comprise a spectrum sensing device, a color calibration processor, and a calculation unit. The spectrum sensing device may be configured to measure color component power spectra for pixels generated by one or more display devices on a display surface. The color calibration processor may receive power spectra for a given pixel from the spectrum sensing device and compute a set of transformation parameters in response to the power spectra. The transformation parameters characterize a color correction transformation for the given pixel. The color calibration processor may compute such a transformation parameter set for selected pixels in the pixel array. The calculation unit may be configured to (a) compute initial color values for an arbitrary pixel in the pixel array, (b) compute modified color values in response to the initial color values and one or more of the transformation parameter sets corresponding to one or more of the selected pixels, and (d) transmit the modified color values to the display device.

The invention relates to light emitting devices (2) with variable output color. More specifically, the inventions provides a color conversion cell (10) which can be positioned in front of a light source (4) in order to generate other color or color temperatures. Typically the light source is a light emitting diode (LED) which is power efficient but emits in a narrow and fixed spectra. The new colors are generated by photoluminescence in fluorescent dyes contained in the cell. The color converting of the cell is electrically controllable, preferably by controlling the orientation, density or distribution of the fluorescent dyes, or by controlling a pathlength of the light in the cell.

A projection display device includes a condensing unit and a shading unit. The condensing unit condenses light emitted from a light source to form a condensed spot on a color wheel. The shading unit, when a size of the condensed spot on the color wheel has increased due to an increase in light emission of the light source, shades a portion of the light passing through the color wheel corresponding to the increased size.

An image display apparatus operates in field sequence mode which effectively reduces the generation of color break. A color break strength calculating unit determines a color break strength that indicates the noticeability of the generation of the color break. A light-source signal generating unit controls each light source so that as the color break strength of a color mixed component having the highest color break strength is higher, the color mixed component is contained more in light output from a light-source unit during the extension subframe period. If there is present a first pixel region as an area including one or more pixel formation regions where an image containing the component of interest is displayed, the color break strength of the component of interest increases more as a magnitude of the component of interest is larger in the first pixel region.

The present invention provides a method and apparatus for color adjustment of a display screen which can provide an interactive user interface which allows a user to perform color adjustment efficiently and effectively.The color adjustment of the display screen in a color display device, such as LCD, CRT or the like, is performed by displaying a color image without any color adjustment at a certain portion of the display screen, displaying a color image with a color adjustment at another portion of the display screen, and referring to the color image without any color adjustment. And to implement this method for color adjustment, the apparatus is configured so that the color images which have passed the color adjustment block and have their colors adjusted, and the color images which have not passed the color adjustment block and are not subject to the color adjustment can be both displayed on the same display screen.

A color determination device sections a hue plane, in which unit data constituting determining image data is mapped, into partial regions by a color determination boundary, and carries out a color determination according to a number of unit data belonging to each partial region. A gradient of a hue boundary line is a rational number. For example, an affine conversion or the like is executed on the hue plane, and the color determination boundary line is matched with an axis of the hue plane. Accordingly, a calculation amount is reduced in a determination processing for determining in which partial region the unit data belongs.

At least one OLED is used to reflect light from at least one other light source such that light from the OLED and the additional light source are combined. Light from the additional light source is reflected from a surface in the OLED provided by e.g., the cathode of the OLED. By carefully selecting the individual light colors of the OLED and the additional light source, their combined light can provide a light color different from either the OLED or the additional light source alone.

Methods and apparatus for combining or separating spectral components by means of a polychromat. A polychromat is employed to combine a plurality of beams, each derived from a separate source, into a single output beam, thereby providing for definition of one or more of the intensity, color, color uniformity, divergence angle, degree of collimation, polarization, focus, or beam waist of the output beam. The combination of sources and polychromat may serve as an enhanced-privacy display and to multiplex signals of multiple spectral components. In other embodiments of the invention, a polychromat serves to disperse spectral components for spectroscopic or de-multiplexing applications.
