Abstract: A color signal emphasizing/de-emphasizing method and apparatus are for outputting image data scanned from the target image in every pixel on a color print or a color display by means of three principle color signals. This method and apparatus are intended to obtain a desired hue variation or color saturation by emphasizing/de-emphasizing one of the three principle color signals. The three principle colors are classified into a primary color portion signal, a secondary color portion signal and tertiary color portion signal. These designated signals of color portions are respectively multiplied by color coefficients predetermined for each designated signal. Finally, a corrected color signal is obtained by summing up these multiplied signals in every principle color.

Abstract: This invention teaches a computerized method for use in data acquisition and manipulation of two-dimensional patterns in the fields of medicine, astronomy, chemistry, biology and biotechnology. The invention teaches an interactive computerized method for matching visual patterns of polypeptide spots in two-dimensional (2-D) gel electrophoretogram solubilized into polypeptide constituents that are separated by electrophoresis. The computerized method manipulates spot pixel coordinates using staged coordinate transformation techniques on spot markers and unknown study spots to reduce gel preparation distortions and allows a user to produce matching results in a manner that compares the transformed spot data using either a single reference gel or multiple reference gels approach for producing the matching results. The method also includes a spot matching verification step and a step to extract potentially mis-matched spots from reported matching results.
