Title: Makoto Saitoh: Innovator in Image Coding Technology

Introduction

Makoto Saitoh is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of image coding technology, holding a total of 4 patents. His work focuses on enhancing the efficiency and quality of image encoding processes.

Latest Patents

One of his latest patents is an image coding apparatus designed for correcting coarseness and encoding uncompressed data. This innovative apparatus obtains a quantization parameter for a macroblock to be encoded and corrects it by adding a specific correction value. The encoding part then encodes the macroblock using this corrected quantization parameter. After encoding, a quantization parameter correction part calculates the cumulative target amount of codes and adjusts the correction value if necessary. This ensures that new macroblocks are quantized more coarsely than previously encoded ones.

Another notable patent is the image coding apparatus and image conversion apparatus. This invention includes a statistical value calculation part that specifies macroblocks around an object macroblock and calculates a minimum average value of their activities. If the images of these macroblocks are flat and the minimum average value is lower than the activity of the object macroblock, it sets this value as an adjustment. A correction factor determination part then determines a correction factor based on this adjustment value, allowing for a more accurate quantization step value that reflects the distribution of macroblock activities.
