    Abstract: Color calibration of color image rendering devices, such as large color displays (1500, 1600), which operate by either projection or emission of images, utilize internal color measurement instrument (1508) or external color measurement modules (1608) locatable on a wall or speaker. A dual use camera (1910, 1943) is provided for a portable or laptop computer (1900), or a cellular phone, handset, personal digital assistant or other handheld device (1930) with a digital camera (1943), in which one of the camera or a display (1904, 1931) is movable with respect to the other to enable the camera in a first mode to capture images of the display for enabling calibration of the display, and in a second mode for capturing image other than of the display. The displays may represent rendering devices for enabling virtual proofing in a network, or may be part of stand-alone systems and apparatuses for color calibration. Improved calibration is also provided for sensing and correcting for non-uniformities of rendering devices, such as color displays, printer, presses, or other color image rendering device.

    Abstract: The present invention transforms a device-dependent color value in a device-dependent color space of a display device to a device-independent color value in a device-independent color space. A first color value is determined in a perceptually linear color space by applying a matrix model to the device-dependent color value, the matrix model applying a tone curve correction and a tristimulus matrix to the device-dependent color value. A difference value is then determined in the perceptually linear color space, wherein the difference value is determined by applying a difference model to the device-dependent color value, and wherein the difference model models deviation of the matrix model from actual measurements of the display device. Next, the difference value and the first color value are added and the sum is transformed to the device-independent color space. Because the first value based on the matrix model is added to a difference value which accounts for deviation of the matrix model, the present invention can account for the channel interdependency prevalent in DLP display devices.

    Abstract: A color uniformity system for correcting color uniformity problems that exist with today's display devices. The inventive device includes a device to measure the color uniformity of the display device and software that uses the information from the measuring system to correct the color uniformity problem on the display device. Probe assembly has so many probes on it that is placed on the display and captures the color information on the display. Measuring assembly measures the color of the signal that comes from the probe assembly. Processor uses the color information from the measuring assembly and also communicates with the host system where the display device is driven from. Software resides on the host system and uses the stored color information to correct the color data that is applied to display device. Hardware unit that resides in the display device and performs color calculations if they are not done in the software.

    Abstract: The invention relates to a method for two-dimensional, spatially resolved measurement of tristimulus values of light emitted from a plurality of positions on a sample. It is an object of the invention to provide an improved method and system for spatially resolved chromaticity and luminance measurement in a standardized color space for display testing. The method of the invention comprises the steps of: - directing a first portion of the light to an RGB camera which produces a two-dimensional map of RGB color values; - transforming the RGB color values into first tristimulus values to produce a map of tristimulus values; - directing a second portion of the light to a colorimeter which produces second tristimulus values; - deriving a tristimulus correction by comparing the second tristimulus values with at least a subset of the first tristimulus values; and - applying the tristimulus correction to the first tristimulus values to produce a corrected map of tristimulus values. Moreover, the invention relates to an imaging colorimeter system capable of two-dimensional, spatially resolved measurement of tristimulus values of light emitted from a plurality of positions on a sample.
