Claim Text:
1. An intra frame prediction scanning method for video coding, comprising steps of: providing a two-dimensional residual coefficient array of a pixel block; dividing the two-dimensional residual coefficient array into a plurality of sub-arrays; converting, in a predetermined order, residual coefficients in the respective sub-array into a one-dimensional individual-sub-array residual coefficient series; connecting the one-dimensional individual-sub-array residual coefficient series of all the sub-arrays as a one-dimensional all-sub-array residual coefficient series of the pixel block; and performing an entropy coding on the one-dimensional all-sub-array residual coefficient series; wherein the sub-arrays corporately form a N×N matrix, each sub-array has a series number (r−1)*N+c, wherein r is a row number of the sub-array in the matrix, c is a column number of the sub-array in the matrix, r and c both are an integer selected between 1 and N, wherein the one-dimensional all-sub-array residual coefficient series is obtained by sequentially connecting the one-dimensional individual-sub-array residual coefficient series of the respective sub-arrays in a head-to-tail manner according to the series numbers of the sub-arrays from small to large.
