An intraprediction encoding and decoding apparatus and method, and a recording medium having recorded thereon a program for performing the methods are provided. The image encoding method includes dividing an input image into at least two sub-planes; performing transformation and quantization on the sub-planes; performing intraprediction encoding on at least one of the transformed and quantized sub-planes; and performing interprediction encoding on at least one remaining transformed and quantized sub-plane that has not been intraprediction encoded by using the at least one intraprediction encoded sub-plane as a reference sub-plane. The decoding method includes receiving an encoded bitstream; entropy decoding the received bitstream; performing intraprediction decoding on at least one intraprediction encoded sub-plane included in the entropy decoded image data; performing interprediction decoding on at least one remaining sub-plane included in the entropy encoded image data using the intraprediction decoded sub-plane as a reference sub-plane; and performing inverse quantization and inverse transformation on the decoded sub-planes. |
