- encoding means for encoding the multi-level image and the created image by using different coding schemes; and
- transmitting means for transmitting encoded data encoded by said encoding means.
- 15. An image transmitting apparatus according to claim 14, wherein said encoding means encodes the multi-level portion by using an orthogonal transformation.
