摘要 |
<p>Images are coded with higher efficiency while maintaining the same image quality. An image coding method of coding an image on a block basis, including: transforming (S1201) a two-dimensional array of pixel values of a current block to be encoded, into a two-dimensional array of transform coefficients; determining (S1202), depending on the two-dimensional array of the transform coefficients, a scan order for scanning the transform coefficients of the two-dimensional array; scanning (S1203) the transform coefficients of the two-dimensional array sequentially according to the scan order, to generate a one-dimensional array of the transform coefficients; and coding (S1204) the transform coefficients of the one-dimensional array.</p> |
