Introduction

Mayumi Okumura is a notable inventor based in Osaka, Japan. She has made significant contributions to the field of image processing technology. Her innovative work has led to the development of a patented method that enhances image quality through optimized bit allocation.

Latest Patents

Okumura holds a patent for a transcoder and coded image conversion method. This invention involves a quantization step determination part that inputs an evaluation value indicating the dispersion in a macroblock and its average value. A subtracter calculates the difference between these values, while a multiplier derives a weighting value. An adder then combines this weighting value with an average quantization step value of the source data. Finally, a multiplier adjusts the sum by a step value adjustment factor to produce a converted quantization step value. This process optimizes bit allocation according to the activity value of the macroblock, thereby improving image quality. She has 1 patent to her name.
