Title: Innovations by Lee A Cass
Introduction
Lee A Cass is a notable inventor based in Rochester, NY (US), recognized for his contributions to color image processing technology. With a total of 2 patents, Cass has made significant advancements in the field, particularly while working at Xerox Corporation.
Latest Patents
One of his latest patents is the "Operator Adjustable Color Image Processing." This invention features an operator-controllable apparatus that adjusts the color of a copy being reproduced from a multi-colored original document. The original document is scanned, and a set of primary color densities is measured. These measured densities are then converted into a set of colorimetric coordinates, which the operator can adjust to achieve the desired hue, saturation, and darkness. The adjusted coordinates are transformed into a set of subtractive primary color densities, which control the marking engine to produce a copy that meets the operator's specifications.
Another significant patent is the "Color Image Processing Apparatus." This apparatus records a latent image corresponding to one of the color components of an original document on an image receiving member. The original document is scanned, and multiple color components are detected. Color signals representing each detected component are generated. As the latent image is recorded, regions of the image where the color signals have a preselected relationship are erased, enhancing the quality of the final output.
