Title: Irwin Sobel: Innovator in Imaging Technology
Introduction
Irwin Sobel is a notable inventor based in Menlo Park, CA (US), recognized for his contributions to imaging technology. He holds a total of 3 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
One of Sobel's latest patents is an inking system that includes reusable paper and water-humectant ink. This special ink consists of water and a humectant, allowing for prints on reusable paper that are visible for a limited time. The reusable paper features a surface darkened by a water-insoluble material, and the coating scatters light when dry, becoming translucent when wet. The ink can be applied using an inkjet printer, making it a practical solution for temporary printing needs.
Another significant patent is related to color halftone error-diffusion with local brightness variation reduction. This algorithm enhances the quality of color images by incorporating a design rule based on human color perception. By adding the Minimum Brightness Variation Criterion (MBVC) to the error-diffusion paradigm, Sobel's method achieves superior output quality without requiring additional memory or significantly increasing run-time.
