IMAGE-DATA BINARY ARITHMETIC DECODING DEVICE AND IMAGE DECODING DEVICE |
| 摘要 |
An image-data binary arithmetic decoding device binary arithmetic decodes a binary string in which continuous 1s and a terminating 0 constitute a prefix. The image-data binary arithmetic decoding device includes continuous-one number determination means for comparing a range of binary arithmetic decoding and a binary arithmetic decoding offset obtained through looking ahead N bits from a bitstream where N is a natural number, and determining the number of continuous 1s in a binary string of the N bits. |

1. An image-data binary arithmetic decoding device for binary arithmetic decoding a binary string in which continuous 1s terminated by 0 constitute a prefix, the image-data binary arithmetic decoding device comprising:
a continuous-one number determination unit which compares a range of binary arithmetic decoding and a binary arithmetic decoding offset obtained through looking ahead N bits from a bitstream where N is a natural number, and determining the number of continuous 1s in a binary string of the N bits. |
