发明名称 Process for extracting a particular color image of an object and a color processing device therefor
摘要 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.
