An apparatus and method are provided for processing image data using error diffusion. The apparatus and method decode image data compressed in a joint photographic experts group (JPEG) format, convert the image data into color coordinates without storing the image data in a memory, and perform a binarization by calculating error values in accordance with the image data in the unit of block to generate a final output data which is 1 bit long. Since the apparatus and method for processing image data using error diffusion do not require an operation of transmitting and storing the image data to a system memory through a DMA controller, the performance of a system is improved. Also, since the memory does not require a large storage space to store the decoded image data, its utility is improved.
