Title: Innovations in Color Imaging by Said Zandian
Introduction
Said Zandian is an accomplished inventor based in Agoura, CA, known for his significant contributions to the field of color imaging. With a total of 3 patents to his name, Zandian has developed innovative techniques that enhance the quality of printed images. His work focuses on improving image clarity, sharpness, and tone continuity through advanced error diffusion processes.
Latest Patents
Zandian's latest patents include groundbreaking methods for multi-level and bi-level printers. In his multi-level printer patent, he describes a process where each pixel, or pel, is selectively enhanced based on an error diffusion technique. Each color channel, such as RGB or Lab, is processed individually using a suitable kernel, allowing for a multi-color image output. The printer can provide various levels of enhancement for each pel, with correlation bins defined for associating desired and actual levels of enhancement. This innovative approach significantly improves image quality by diffusing error values to neighboring pels.
In his bi-level printer patent, Zandian employs a similar error diffusion process, but with an individual threshold level calculated for each color channel. This method also enhances the clarity and sharpness of the printed images. The reversal of processing order and error diffusion matrix for each subsequent line of pels further contributes to the overall improvement in image quality.
Career Highlights
Throughout his career, Zandian has worked with notable companies in the imaging industry. He has been associated with Data Products Corporation and Hitachi Koki Imaging Solutions, Inc., where he applied his expertise in color imaging technologies. His innovative approaches have made a lasting impact on the field.
