Latest Patents

Among Toshiaki Endoh's notable inventions is a high efficiency coding method for still natural images. This method processes an original grayscale or color image through a bi-level image mingled still image coding system to yield a differential image. The patented technique intelligently compares the original image and this differential image for each pixel block. It selectively encodes pixel blocks using either the bi-level system or a natural image coding system, based on efficiency, particularly in areas with abrupt pixel value changes, such as edges of text or intricate multi-colored images. This results in a high-quality coded image with minimal deterioration.

Another patent demonstrates an innovative image reduction system for binary level images. This system utilizes a filtering operation that references multiple surrounding pixels, including those that have already been reduced. The process includes an exception mechanism to correct binary level results when a specific pattern is present among the referenced pixels, ensuring improved accuracy during image reduction.
