Title: Hiroyuki Matsumoto: A Visionary in Optical Innovations
Introduction: Hiroyuki Matsumoto, located in Kishiwada, Japan, is a renowned inventor with an impressive portfolio of 34 patents. His contributions to the field of optical systems and image capturing technologies have significantly advanced modern imaging devices.
Latest Patents: Among Matsumoto's latest inventions are two noteworthy patents. The first is a "Large aperture zoom optical system and image pickup apparatus," which features a five-lens-group arrangement characterized by positive-negative-positive-negative-positive refractive powers. During the zooming process, the fifth lens group remains fixed while the second, third, and fourth lens groups are actively moved. Notably, the third lens group, which is crucial for focusing, consists of a single lens element.
The second patent, titled "Zoom lens system, imaging optical device, and digital appliance," describes a zoom lens system made up of negative, positive, negative, and positive lens groups. In this system, at least the first to third lens groups shift during zooming. As the zoom transitions from the wide-angle to the telephoto end, the distances between these lens groups change according to specific conditions, ensuring optimal performance.
Career Highlights: Matsumoto’s career includes significant contributions while working with notable companies such as Minolta Company, Ltd. and Konica Minolta Photo Imaging, Inc. Throughout his tenure, he has played a critical role in the development of advanced optical systems that cater to both consumer and professional markets.
Collaborations: His innovative journey is also marked by collaboration with skilled professionals, including coworkers Atsuo Masui and Tetsuo Kohno. Together, they have explored various avenues of optical technology, pushing the boundaries of what is possible in imaging systems.
Conclusion: Hiroyuki Matsumoto stands as a pivotal figure in the realm of optical innovations. His patents reflect a deep understanding of optical mechanics and a commitment to advancing imaging technologies. His work continues to inspire future generations of inventors and innovators in the field.
