Title: Masami Aragaki: Innovator in Image Data Compression
Introduction
Masami Aragaki is a prominent inventor based in Kyoto, Japan, known for his significant contributions to the field of image data compression. With a total of five patents to his name, Aragaki has developed innovative methods that enhance the efficiency of image processing.
Latest Patents
Aragaki's latest patents include a method of an apparatus for compressing image data. This invention involves conceptually dividing an image into pixel blocks, each containing multiple pixels. The RGB image data is converted into luminance and color difference data in the NTSC format. Standard deviation values of these data are calculated for each pixel block and compared with threshold values, allowing for the classification of pixel blocks into two types. The image data in these blocks are then compressed at different rates to achieve optimal compression. Another notable patent is a method of and apparatus for compressing image data, where image data is transformed using a 2-D Discrete Cosine Transformation into transformation coefficients. Only a portion of these coefficients is used to create compressed image data, with the selection process guided by code tables. This innovative approach ensures that the compressed data can be effectively restored by storing identification data that specifies the selected group used during compression.
