Electronic device and method for splitting image

摘要

In a method for splitting an image for encoding purposes, a largest coding unit (LCU) of the image is obtained, the LCU is divided into a plurality of coding unit (CU) blocks (S10), the CU blocks examined sequentially (S11), and a determination made as to whether or not a current CU block needs to be split according to a pixel variance of the current CU block (S12). The current CU block is split into four sub-blocks if the current CU block needs to be split (S13).
