Abstract: An image encoding method using a Binary Partition Tree (BPT) includes performing the BPT on a reference frame, detecting blocks, each having a difference in a pixel value exceeding a threshold value in a current frame, based on a result of the BPT of the reference frame, and performing the BPT of the current frame on the detected blocks. In accordance with the present invention, block partition is not applied to all frames, but a partial partition method based on a difference between the pixel values of a reference frame and a current frame to be encoded is provided. Accordingly, the encoding speed within the P frame or the B frame can be improved. Furthermore, the PSNR of a corresponding frame can be maintained within a specific range of the PSNR of a reference frame, and a compression effect can be improved.
