Title: Innovations of Donald C Bellis, Jr.
Introduction
Donald C Bellis, Jr. is a notable inventor based in Rochester, NY (US). He has made significant contributions to the field of imaging technology, holding a total of 3 patents. His work primarily focuses on improving color reproduction and image data metrics.
Latest Patents
One of his latest patents is titled "Method and apparatus for forming a source-independent image data metric." This invention presents a technique for enhancing the tone and color reproduction of print and slide images that are photographed onto color negative film, scanned by a Photo CD negative scanner, and transferred onto Photo CD discs. The technique includes a calibration method that produces color negatives using normal scanner calibration targets, controlled prints from the negatives, and re-photographing the prints onto a second color negative film. This calibration step ensures that the image data recorded on the Photo CD disc closely resembles the data that would be produced if the original scene had been photographed directly.
Another significant patent is "Method and apparatus for improving the color rendition of hardcopy." This invention involves processing a three-color signal produced by an electronic color image sensor, such as the Kodak KAF-1400 sensor. The process includes additive-type color correction in a linear domain and subtractive-type color correction, ultimately converting the signals into a format suitable for color printing. The invention also addresses noise enhancement problems and enhances the sharpness of the color print.
