Title: The Innovative Contributions of Shinji Asada
Introduction
Shinji Asada is a notable inventor based in Kyoto, Japan. He has made significant contributions to the field of image processing, holding a total of six patents. His work has had a profound impact on how image signals are converted and processed in various applications.
Latest Patents
One of Shinji Asada's latest patents involves a method and apparatus for converting image signals that represent an image. In this innovative approach, an original image is divided into multiple pixel blocks, each containing several pixels. A density histogram is generated for each pixel block, represented by an electric signal. The pixel blocks are then analyzed to identify adjacent blocks that are uniform and continuous in density. If these blocks are found to be continuous with reference pixel blocks located at the corners of the original image, they are classified as representing the background portion of the image. The density histogram is corrected for each background pixel block, and highlight and shadow points are determined to establish a gradation curve. This gradation curve is then utilized in a signal converter to effectively convert the image signal representative of the original image.
