Title: The Innovations of Ryuzo Motoori
Introduction
Ryuzo Motoori is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of image processing and scanning technology. With a total of 13 patents to his name, Motoori's work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is an image scanning signal generating apparatus with pre-scan for exposure. This innovative apparatus includes an optical system that focuses the image of a photographic film onto a predetermined plane. A scanning device scans the image with a photoreceptor positioned at the predetermined plane, generating output signals that represent the light intensity distribution of the film. The scanning device performs a first scan to detect the maximum and minimum density levels of the film, followed by a second scan where the exposure of the photoreceptor is controlled based on the detected levels. Additionally, during the second scan, the output signals are clamped to a calculated clamp level based on the detected maximum and minimum density levels from the first scan.
Another significant patent is the image processing apparatus in film image phototelegraphy. This apparatus is designed for a phototelegraphic system that transmits film images. It features a frame for holding the film, a line sensor consisting of an array of CCDs for reading the film image, and a main scanning direction frame signal elimination circuit. This circuit eliminates signal components corresponding to the frame from the maximum and minimum densities detected by a peak hold circuit. A microcomputer is also included to detect signal components from subscanning image signals, effectively eliminating noise components in the image signals due to frame presence or film soiling.
