We have developed a low power MPEG1 (Moving Picture Expert Group)/JPEG (Joint Photographic Expert Group) encode/decode single chip IC (codec). Using compact ME (motion estimation) process and a power management function we realize a low power consumption. Total power consumption of the codec is 500 mW. Using this chip, we have also developed a compact digital camera for the MPEG1 stream.
