METHOD AND APPARATUS FOR ARRANGING PIXELS OF PICTURE IN STORAGE UNITS EACH HAVING STORAGE SIZE NOT DIVISIBLE BY PIXEL SIZE

摘要

A data arrangement method includes following steps: obtaining pixel data of a plurality of first N-bit pixels of a picture;and storing the obtained pixel data of the first N-bit pixels in a plurality of M-bit storage units of a first buffer according to a block-based scan order of the picture. The picture includes a plurality of data blocks,and the block-based scan order includes a raster-scan order for the data blocks. At least one of the M-bit storage units is filled with part of the obtained pixel data of the first N-bit pixels,M and N are positive integers,M is not divisible by N,and the first N-bit pixels include at least one pixel divided into a first part stored in one of the M-bit storage units in the first buffer and a second part stored in another of the M- bit storage units in the first buffer.
