Abstract
In a method for splitting an image for encoding purposes, a largest coding unit (LCU) of the image is obtained, the LCU divided into a plurality of 2N×2N blocks, the 2N×2N blocks examined sequentially, and a determination made as to whether or not the current 2N×2N block needs to be split according to a pixel variance of the current 2N×2N block. The method further determines whether a block merging operation needs to be executed for the LCUs according to an average value of pixels of each of the 2N×2N blocks if the current 2N×2N block does not need to be split.
