ALEXANDRIA, Va., May 19 -- United States Patent no. 12,634,500, issued on May 19, was assigned to KDDI Corp. (Tokyo).

"Moving picture decoding device, moving picture decoding method, and program obtaining chrominance values from corresponding luminance values" was invented by Kei Kawamura (Fujimino, Japan) and Sei Naito (Fujimino, Japan).

According to the abstract* released by the U.S. Patent & Trademark Office: "A decoding device includes a transformer sets a decoded luminance component of a prediction target block to the same number of samples as that of the chrominance component corresponding to the decoded luminance component of the prediction target block and generates a luminance reference signal. A specificator specifies luminance ...
