動画像符号化装置及び動画像符号化方法

Title:

動画像符号化装置及び動画像符号化方法

Document Type and Number:

Japanese Patent JP4922138

Kind Code:

B2

Abstract:

A first prediction unit (101) performs intra-prediction of an original image corresponding to an inter-frame coded frame to produce a first prediction residual and a prediction parameter. A second prediction unit (102) performs intra-prediction of local decode data corresponding to the inter-frame coded data with the prediction parameter to produce a second prediction residual. A subtractor (15) calculates difference data between the first prediction residual and the second prediction residual. A third prediction unit (201) performs intra-prediction of data corresponding to a decoded frame with the prediction parameter to produce a third prediction residual, when the inter-frame coded data is decoded and transformed into the intra-frame coded data. An adder (23) calculates addition data of the third prediction residual and the differential data. An intra-frame coding unit (202) performs intra-frame coding to the addition data.
