Title: Ikuo Okuma: Innovator in Image Recording Technology
Introduction
Ikuo Okuma is a notable inventor based in Nagaokakyo, Japan. He has made significant contributions to the field of image recording technology, holding a total of 3 patents. His work focuses on improving error detection and correction in digital image data, which is crucial for enhancing the quality and reliability of image recordings.
Latest Patents
Okuma's latest patents include an innovative image recording system that performs error correction repeatedly. According to the first aspect of this invention, digital image data are recorded in the form of compressed codewords with check information and flags. The flags indicate codewords containing uncorrected errors. Each time the data are copied, error detection and correction are performed, and the flags are updated to indicate any new uncorrectable errors that are detected. The flags can be utilized for error concealment, to avoid error miscorrection, and to permit the check information to be regenerated each time the data are copied. The second aspect of the invention involves using the same check information to perform error detection and correction twice when image data are copied. Flags identifying uncorrected errors can be transferred from the first error-detecting-and-correcting process to the second.
Career Highlights
Ikuo Okuma is currently employed at Mitsubishi Electric Corporation, where he continues to innovate in the field of image technology. His work has been instrumental in advancing the capabilities of digital imaging systems, making them more efficient and reliable.
