Title: Kazuhiko Katakura: Innovator in Image Reading Technology
Introduction
Kazuhiko Katakura is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of image reading technology, holding a total of 12 patents. His work focuses on enhancing the efficiency and effectiveness of image reading apparatuses, particularly in relation to photographic materials.
Latest Patents
One of his latest patents is an image reading apparatus and method that simplifies the control process while allowing for suitable adjustments of color balance based on the type of photographic material. This innovation involves acquiring the type of photographic film to be read. If the film is a negative or sepia-tone film, a filter for negative film is set on the optical axis of illumination light. Conversely, if the film is a positive or black-and-white film, a filter for positive film is utilized. In both scenarios, the film image is effectively read.
Another notable patent is a device designed to prevent the degeneration of photographic photosensitive materials and an image reading apparatus. This invention employs a flow sensor to detect the cooling air flow rate from a compressor. It determines whether the detected flow rate is abnormal. Additionally, a diaphragm position sensor assesses if the diaphragm is in a critical position that could lead to excessive light exposure on the photographic film. If the diaphragm is in this critical position and the cooling air flow rate is abnormal, the lamp is turned off to protect the film.
