1. An image processing apparatus comprising:
an input frame buffer configured to store an input original frame;
an encoding processor configured to encode the stored original frame;
an output stream buffer configured to output the encoded original frame as an output stream for multiplexing;
a multiplexing processor configured to control the output stream to be multiplexed and transmitted;
a local decoding processor configured to output a restored stream by receiving the output stream from the output stream buffer and decoding the output stream;
a restored frame buffer configured to store the output restored stream; and
a machine learning processor configured to collect the input original frame and the restored frame decoded at the local decoding processor and stored at the restored frame buffer, output a parameter based on machine learning of the collected original frame and the collected restored frame, and control the multiplexing processor to transmit the output parameter to a decoding side.
