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 monitor calibrator housing and mounting bracket for storing the housing in either the horizontal or vertical positions. The housing includes opposing, side, contoured, finger receptacles, and a suction cup at one end. The mounting bracket includes first and second parts. The first part includes a flat portion and a perpendicular U-shaped portion. The second, separate part is a curved member having a first recess for receiving a curved free end of the flat portion, and a portion of the suction cup, and a second recess for supporting a portion of the housing. When the calibrator is removed from a monitor, it can be placed in the first part, which rests horizontally on e.g., a desk top. In this position, the suction cup rests on the flat portion of the first part. The calibrator and the first mounting bracket can also be placed in the second mounting bracket part, which is removably connected to a vertical surface, such as a CRT side panel.

Abstract: A method for achieving a target white chromaticity value and a target white light output value on a display device includes measuring a chromaticity value of a first primary color, a chromaticity value of a first secondary color, and a chromaticity value of a second secondary color on the display device using a photometer. The method also includes measuring a current white chromaticity value and a current white light output value on the display device using the photometer. The method also includes generating a plot of a color gamut triangle based at least partially upon the measured chromaticity value of the first primary color, the measured chromaticity value of the first secondary color, the measured chromaticity value of the second secondary color, and the measured current white chromaticity value.

Abstract: Color calibration of color image rendering devices, such as large color displays, which operate by either projection or emission of images, utilize internal color measurement instrument or external color measurement modules locatable on a wall or speaker. A dual use camera is provided for a portable or laptop computer, or a cellular phone, handset, personal digital assistant or other handheld device with a digital camera, in which one of the camera or a display 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.
