Modifying wavelet division level before transmitting data stream
First Claim
1. An image processing apparatus, comprising:
- a memory which stores a code stream having a wavelet division level;
an interface unit which transmits the code stream to another apparatus; and
a processing unit which changes the wavelet division level of the code stream before the transmission of the code stream to said another apparatus by acquiring a target division level that is a wavelet division level of said another apparatus, checking a difference between the target division level and the wavelet division level of the code stream, generating data that compensates for the difference, and embedding the generated data into the code stream.

Abstract
An image processing apparatus includes a memory which stores a code stream having a wavelet division level, an interface unit which transmits the code stream to another apparatus, and a processing unit which changes the wavelet division level of the code stream before the transmission of the code stream to such another apparatus by acquiring a target division level that is a wavelet division level of such another apparatus, checking a difference between the target division level and the wavelet division level of the code stream, generating data that compensates for the difference, and embedding the generated data into the code stream.

6. A computer-readable record medium having a program embodied therein for causing a computer to transmit a code stream having a wavelet division level to another apparatus, said program comprising the steps of:
-
acquiring a target division level that is a wavelet division level of said another apparatus;
checking a difference between the target division level and the wavelet division level of the code stream;
generating data that compensates for the difference; and
embedding the generated data into the code stream so as to change the wavelet division level of the code stream before the transmission of the code stream to said another apparatus. - View Dependent Claims (7, 8, 9, 10)
