The present application provides a method for storing an image frame in a memory, including: receiving the image frame; dividing the image frame into M rows of data block rows along a first direction; dividing each of the M rows of data block rows into N data blocks along a second direction perpendicular to the first direction; performing a compression operation upon each of the M*N data blocks individually to generate M*N compressed data blocks; and storing N compressed data blocks corresponding to the 1st data block row of the M data block rows and N compressed data blocks corresponding to the (P+1)th data block row of the M data block rows in a continuous storage space in the memory, wherein M, N, and P are integers, and M>1, N>0 and P
