Abstract
Image processing method and apparatus for converting between data encoded in different formats includes structure and steps for converting motion image data into first digital coded motion image data having a first encoding format and capable of being transmitted to a medium. The first digital coded motion image data is then converted into second digital coded motion image data without decoding entirely the first digital coded motion image data. The second digital coded motion image data has a second encoding format different from the first encoding format. Preferably, the second digital coded motion image data has a digital data amount which is less than that of the first digital coded motion image data.
