Title: Masahiro Tamegai: Innovator in Imaging Technology
Introduction
Masahiro Tamegai is a prominent inventor based in Tochigi, Japan. He has made significant contributions to the field of imaging technology, holding a total of 7 patents. His work focuses on developing advanced methods for image processing and radiation dosimetry.
Latest Patents
Tamegai's latest patents include an image photographing apparatus and method. This innovative image processing method generates a small number of still images from a plurality of projected time-series images obtained in time series. The method involves storing the time-series images and performing subtraction between pixel values of different time-series images. It also detects motion by comparing the difference value obtained from the subtraction with a threshold value. The stored images are then synthesized to generate a predetermined number of synthesized images.
Another notable patent is related to area exposure dosimetry and area absorbed dosimetry. This patent calculates the area of an irradiation region and the areas of object and non-object regions in a radiation image. It acquires the effective dose of radiation from a radiation generator and calculates the area exposure dose based on the irradiation region and effective dose.
