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.

The invention relates to a method and apparatus for color matching of slightly colored objects which are transparent, diffusing an absorbent, by acuminating a small error of the objects with a first bunch of optical fibers. A second bunch of optical fibers is used to pick up the light back scattered from the area of the objects. The second fibers are located inside of the illuminating fibers. The light is measured at 3 wavelengths that correspond to blue, green and red colors and the pigmentation of the object is calculated as a difference between the red and blue spectrum components. Presentation of the brightness is calculated to be proportional to the green spectrum component. The pigmentation and brightness is then compared with the same perimeters of a standard shape pallet. The invention is particularly suitable for color matching the teeth in the mouth with dental prosthesis and dental restorative materials.

Spectrally coordinated pattern search-imaging system and method
InactiveUS6122391AChoose simpleDigital data information retrievalTexturing/coloringColor imageCD-ROM
A system for selecting decorative materials is based on large numbers of high-resolution, full color images of decorative materials stored in a compressed format on an inexpensive medium such as a CD-ROM. In creating the ROM, each image is coordinated with additional information such as style of pattern, type of material, and other auxiliary information. Before final compression and storage of the image data color information is added by spectrophotometrically analyzing the decorative material. Color values for a background color and up to four foreground colors are determined. Individual colors are then referenced to a comprehensive color standard system containing a large number of standardized color swatches. Spectrophotometric color referencing allows the data records to be rapidly searched on the basis of color, as well as the other information in the record. Wallpaper patterns, drapery material, floor covering, or paint can then be rapidly selected on the basis of matching color. Various patterns and paints can be compared side by side on a high-resolution computer monitor that has been calibrated to produce an accurate color image. Finally, the chosen paints and other decorating materials can be rendered onto a room image so that the consumer can view an accurate simulation of the chosen materials.
