Title:
MOVING-IMAGE DECODER, MOVING-IMAGE DECODING METHOD, MOVING-IMAGE ENCODER, MOVING-IMAGE ENCODING METHOD, AND COMPUTER READABLE RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/055910
Kind Code:
A1
Abstract:
A moving-image decoder provided with a decoding means for decoding a bit stream that represents a moving-image including a block that is encoded using intra prediction, an inverse processing means for inverse-quantizing and inverse-transforming the level value of the block obtained as a result of the decoding and generating a differential pixel value of the block, an intra prediction means for generating the predicted pixel value of the block by intra prediction based on the pixel values of reconstructed blocks around the block, and a reconstruction means for reconstructing the block on the basis of the generated differential value and the generated predicted value. The intra prediction means synthesizes a plurality of lines of reconstructed blocks around the block and thereby generates a reference line used in the intra prediction.
