Title: Hidenori Aotake: Innovator in Picture Processing Technology
Introduction
Hidenori Aotake is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of picture processing technology, holding a total of 6 patents. His work primarily focuses on enhancing the efficiency and effectiveness of image encoding and processing systems.
Latest Patents
Aotake's latest patents include a picture processing apparatus that utilizes screen change parameters to represent a high degree of screen change. This invention involves an MPEG1 real-time encoder board that generates index data as an evaluation value representing the complexity of a picture. A scene change parameter is calculated from this index data, which indicates the degree of a scene change occurring in the picture. This parameter is associated with a scene change pointer, providing position information on where the scene change occurs. Both the scene change parameter and pointer are recorded as an index in an index file, while the MPEG system stream output by the encoder board is stored separately in an MPEG file.
Another significant patent involves a recording apparatus, method, and medium. In this invention, a recording period for a program and the bit rate of an MPEG system stream produced by the encoder board are set. A microprocessor computes the recording capacity based on these parameters, allocating a free area in the hard disk equal to the computed capacity. This area is then used for storing the MPEG system stream received by a TV tuner employed in the encoder board.
