Abstract: A method for creating a uniformity compensation look-up table is revealed. The method includes the following steps. First measure a plurality of areas on a plane users intend to make uniform to get a measured value of the respective area. Then get a central uniform estimate of a center of the plane. Also get a linear skeleton according to the position of one of the measured values and the position of the central uniform estimate. Next get a plurality of skeletal uniform estimates on the linear skeletons respectively by interpolation or extrapolation of the measured values, the central uniform estimate, and the distance between the position of the measured values and the center of the plane. At last get a plurality of planar uniform estimates on the plane in turn according to the skeletal uniform estimates of the two adjacent linear skeletons to establish the look-up table.

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.

Abstract: A color processing device includes the following elements. An image data obtaining unit obtains image data which is obtained by imaging a white member illuminated by a light source and a display device on which a white image is displayed. A color component extracting unit extracts color components of red, green, and blue from image data concerning the white member and image data concerning the white image. A relation determining unit determines a relation between a color temperature and/or a brightness level of the light source and a color temperature and/or a brightness level of the white image, on the basis of a magnitude relation of the extracted color components.
