IMAGE ENCODING METHOD, IMAGE DECODING METHOD, IMAGE ENCODING APPARATUS, IMAGE DECODING APPARATUS, AND IMAGE ENCODING/DECODING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2013/011640
Kind Code:
A1
Abstract:
An image encoding method comprises an encoding step (S801) for encoding first binarized data, which indicates a first intra prediction mode, and second binarized data, which indicates a second intra prediction mode. The encoding step (S801) uses a context adaptive arithmetic encoding to encode a first context adaptive portion, which is a portion of the first binarized data, and a second context adaptive portion, which is a portion of the second binarized data, and further uses a bypass encoding to encode a first bypass portion, which is another portion of the first binarized data, and a second bypass portion, which is another portion of the second binarized data, thereby generating encoded data that includes the first and second context adaptive portions and that also includes the first and second bypass portions following the first and second context adaptive portions.
