Abstract: A color information file is produced in a processor for the communication of colors, which file can include all possible information data assigned to one or several color samples and identifying, characterizing or supplementing them. The information data are stored as data objects in the data information file in an open and expandable hierarchically organized object structure on XML basis in text format. By embedding the data objects in an XML container, it is possible to characterize color samples by way of arbitrary and different combination of information data and to selectively add complementary image or text information. The color information file is produced with the help of a text editor or a composer software, for example with graphic user interface. A viewer software is provided for the reading of the color information file and for interpretation of the information data stored therein.

Abstract: The invention relates to a method for determining a patient's tooth shade that includes the steps of electronically imaging a patient's tooth to obtain an image which includes color information representative of tooth color; determining the patient's tooth color from the color information of the image; and displaying the determined tooth color to identify one or more tooth shades having a combined color corresponding to the determined tooth color. Preferably, the displayed data includes RGB chromaticities of the color image, and the patient's tooth color is determined by averaging the color information at selected locations of the image which correspond to different spatial locations of the patient's tooth. If desired, the color information of the patient's tooth can be electronically stored for use at a later time.

Abstract: An intraoral camera connects to a shade analyzer subsystem, e.g., a digital video processor, and a color display monitor. The camera captures a digital color image of the patient's tooth and the subsystem compares that image to a stored plurality of tooth shades. Each tooth shade is represented in a block of data, including color image data, a tooth shade digital word, and a manufacturer type. The patient's tooth image includes an RGB chromaticity representation that is scanned and compared with the several tooth shades stored in memory, and a match is determined and communicated to a user of the system. The methodology includes the specification of fractional tooth shades, if needed, corresponding to a plurality of porcelain films for manufacturing a reconstructed tooth.

Abstract: A pattern extracting apparatus extracts a pattern of a desired color from an object containing a plurality of color patterns. In the apparatus, the object is irradiated by light to provide data relating to color components and the data relating to color components are converted into Munsell color data H (Hue), V (Value) and C (Chroma). After that, a pattern of a specific color is extracted from the object based on the Munsell color data.

Abstract: A color image processing system includes a color television camera monitoring an object to provide a video signal comprising three primary color components, and a color determination section which defines particular hue, chroma, and brightness regions. The video signal from the camera is analyzed at the color determination section in such a manner as to determine the video signal denotes the particular hue, chroma, and brightness when the three primary color components are found to fall within the particular hue, chroma, and brightness regions, respectively. Thus determined video signal is extracted as forming individual color signals indicating filtered images of the object with regard to the particular hue, chroma, and the brightness, respectively. A logic circuit is included in the system to perform a suitable logical function with regard to thus extracted color signals and to generate an output indicating an image of the object reflecting the result of the logical function, which is processed in an image deriving section to obtain geometrical characteristics including a location, area, and profile of the object with regard to a suitable combination of the filtered images.
