Title: Innovations by Kouji Shibuno: Enhancing Camera Technology
Introduction: Kouji Shibuno, an accomplished inventor located in Osaka, Japan, has made significant contributions to the field of camera systems. With five patents to his name, Shibuno's innovations focus on improving autofocus mechanisms and image pickup technologies. His work has been instrumental in advancing the functionality and performance of modern cameras.
Latest Patents: Among Shibuno's latest inventions are two notable patents. The first patent presents a camera system where a lens controller retrieves an exposure synchronizing signal from the camera body. This system utilizes a configuration consisting of a first encoder, a second encoder, and a counter to accurately determine the position of a focus lens based on the received signal. By associating the focus lens position with an autofocus (AF) evaluation value, the camera controller can enhance the autofocus operation's precision using a contrast system.
The second patent introduces an image pickup device incorporating a moving focusing lens. In this invention, when a mode switch selects the finder mode, the focusing lens is driven at a high speed during focus operations. Conversely, when the live view mode is activated, the driving speed is adjusted to a lower range based on the detected brightness of the object. This innovative approach allows for a versatile lens driving control method that adapts to different autofocus systems, ensuring high-speed focusing operations.
