Techniques for compressing decompressing image data are disclosed. An image compression / decompression apparatus according to an international standard comprises a control unit (2), a pixel processing unit (3) for discrete cosine transformation and quantization, an interval buffer memory. image (51), a motion prediction unit (41), a pixel data bus (PB) and a code bus (CB). An assembly control processor which is incorporated in the control unit performs pipeline control for image compression / decompression, thereby achieving high operation. Application to the transmission of television images. |
