Hirohiko Ina

Title: The Innovative Mind of Hirohiko Ina

Introduction

Hirohiko Ina is an accomplished inventor based in Nishinomiya, Japan, known for his contributions to camera technology. With a total of four patents to his name, his work focuses on enhancing photographic methods and camera functionalities.

Latest Patents

Among Hirohiko Ina's latest inventions are the motion verifying camera and the motion verifying photography method. In this unique photography method, a latent image is captured during a specific film exposure time interval that consists of an initial portion, a middle portion, and a final portion. The first digital image is recorded during the initial segment, while the second digital image is captured at the close of the exposure interval. These two electronic images are then visualized together, offering a dynamic representation of motion.

The motion verifying camera itself is engineered with an exposure frame and an electronic array imager, strategically spaced apart. The design includes an optical system that directs light along dual paths to both the exposure frame and the imager. Equipped with shutters on both paths, the system utilizes an actuator that momentarily opens the film and imager shutters at defined intervals during the exposure time.

Additionally, Hirohiko Ina has developed an electric zoom camera that maintains consistent zooming speed, unaffected by fluctuations in power source voltage. This innovative camera achieves this by driving the zooming electric motor using an electric pulse current, which divides each zoom period into off and duty portions. The first portion, where motor current is off, is calibrated to adapt according to the current zooming speed indicated by the lens position signal generated by the lens position detector.
