METHOD FOR ENCODING/DECODING HIGH-RESOLUTION IMAGE AND DEVICE FOR PERFORMING SAME

摘要

A method for encoding/decoding a high-resolution image and a device for performing same set the size of an expansion macro-block as the size of a prediction unit to be encoded, according to a temporal frequency feature or a spacial frequency feature found therebetween at least one picture to be encoded, perform motion prediction and motion compensation using the set prediction unit size unit, and perform the conversion thereof. Also, a macro-block having 32x32 pixel or 64x64 pixel size is divided into at least one partition based on an edge, and encoding is performed on each of the divided partitions afterwards. Therefore, encoding efficiency for high definition (HD) or higher resolution images is enhanced.
