Katsuhisa Ashizawa is a notable inventor based in Yamanashi, Japan. He has made significant contributions to the field of color image processing, showcasing his innovative spirit through his patented technology.

Latest Patents

Ashizawa holds a patent for a color image processing device. This device utilizes a dither pattern of blocks, each containing multiple dots that represent the gradations of each pixel within a designated print region. The dots within a block are arranged in a growth sequence according to the ascending order of gradation. Print data is sequentially written at the dots corresponding to the gradation associated with the block. An extracting unit is responsible for extracting a data region that holds the color components from the print data. Additionally, a dither processing unit generates dither patterns for the extracted color components. This unit also detects if any dots, which include pixels forming the image, are outside the data region and moves them to a corresponding dot within the data region.
