DYNAMIC IMAGE ENCODING METHOD, DYNAMIC IMAGE DECODING METHOD, AND DEVICE THEREOF |
摘要 |
The moving picture encoding method of the present invention is for orthogonally transforming pixels which constitute a block into coefficients indicating frequencies, quantizing the coefficients, and encoding the quantized coefficients. The method includes: selecting quantized coefficients belonging to a subset of a block, from the block of frequency coefficients which are either the coefficients prior to quantization or the quantized coefficients; and altering the arrangement of the subset in the block. Here, the arrangement of the subset is altered in relation to at least one of the following (i) to (v): (i) the completion of encoding a picture; (ii) the completion of encoding a predetermined number of blocks; (iii) content of a current picture to be encoded; (iv) the position of a block in a picture; and (v) a comparison between each frequency coefficient and a threshold. |
