Title: The Innovative Contributions of Takamasa Sakamoto
Introduction
Takamasa Sakamoto is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of optical technology, particularly in the development of advanced zoom lenses and digital cameras. With a total of 12 patents to his name, Sakamoto's work has had a lasting impact on the industry.
Latest Patents
One of Sakamoto's latest inventions is a zoom lens that includes a plurality of lens groups. This innovative design allows the lens groups to align on a common optic axis during operation, forming a first and second plane conjugated with the first plane. To achieve miniaturization, at least one lens group can be rotated around an axis perpendicular to the common optical axis, while others are moved along the optical axis. This results in a shortened overall length when the zoom lens is retracted.
Another notable patent is for a digital camera featuring a collapsible lens barrel. This design retains optical performance while maintaining a slim profile when closed. The camera includes two lens groups installed in a collapsible barrel, a focus lens, and a CCD for image generation. An evading mechanism allows the lens groups to rotate and position themselves beside the image sensor, preventing offset and resulting in a thin digital camera.
