With a total of 2 patents to his name, Yanagihara's work has had a substantial impact on how images are encoded and transmitted.

Latest Patents

Yanagihara's latest patents include a video image compression/decompression device and an image encoding apparatus. The video image compression/decompression device enhances memory bandwidth utilization during compression and decompression operations while minimizing adverse effects on image quality. This device features a data conversion unit that reduces the data access rate for original and reference images stored in memory. By accessing memory in a different order for data writing and reading, it increases memory bandwidth efficiency and reduces buffer memory capacity.

The image encoding apparatus, on the other hand, enables high bit rate encoding without compromising image quality at the boundaries of a picture. This apparatus includes multiple entropy encoding sections that generate bit streams by entropy-encoding intermediate data derived from image data syntax elements. An encoding control section determines which entropy encoding section will perform the encoding process based on the processing status of each section.
