ABSTRACT:
A method, medium, and system encoding and/or decoding image data by dividing image data into block units, and generating a bitstream by entropy encoding the image data in order of the divided blocks. The decoding method may include receiving an input of a bitstream, and restoring image data by entropy decoding the block units of the bitstream. According to the method, medium, and system, when image data is encoded and/or decoded by using a residue color transform, a bitstream can be generated and encoded in block units of the image, and when the bitstream is decoded, an image can be restored from the bitstream. By doing so, the conventional delay of image processing can be prevented.
